Japanese Patent Laid-Open No. 10-23820

  By the way, at the time of actual farm work, the function of each operating unit is often adjusted in accordance with the phenomenon / situation occurring in the farm machine. When performing such function adjustment work, it is necessary for the operator to understand the structure of the agricultural machine to some extent and to become familiar with the adjustment method. And until you get used to it, you have to do the function adjustment work while looking at the instruction manual of the agricultural machine.

  However, since it is extremely rare to bring instruction manuals to the field during farm work, in many cases the operator does not know which part should be adjusted and how to adjust the function of each operating part. There was a problem that it was virtually impossible. Even if an instruction manual is brought, there is a problem that the function adjustment work while looking at the instruction manual is very troublesome and the work efficiency is not good.

  In addition, when performing the above-described function adjustment work, from the viewpoint of safety, the farm work machine is held in the traveling stop state, and the clutch operating means for switching off the power transmission from the engine to each operating part is switched off. It is necessary to operate. However, there is often a possibility that the operator performs the function adjustment work without forgetting to turn off the clutch operating means. If the function adjustment work is performed in such a state of forgetting to cut, there is a risk that the operator may be caught in the operation part to be adjusted and get injured, which is very dangerous.

  This invention is made | formed in order to eliminate the above problem, and makes it a technical subject to provide the agricultural machine which can perform the function adjustment of each action | operation part safely.

  In order to solve this technical problem, the invention of claim 1 is directed to display means for displaying information on various modes in a farm machine, control means for executing control for displaying the information on the display means, and traveling. A farm working machine having a clutch operating means for intermittently operating power transmission from the engine mounted on the airframe to each of the operating parts, wherein the control means operates the clutch operating means In other words, the mode is shifted from another mode being executed to an adjustment mode in which the function of each operating unit is adjusted, and information on the adjustment mode is displayed on the display means.

  According to a second aspect of the present invention, in the agricultural machine according to the first aspect, when the control means enters and operates the clutch operating means during the execution of the adjustment mode, the original before the transition from the adjustment mode. Returning to the mode, the screen display of the display means is changed from the information of the adjustment mode to the information of the original mode.

  According to a third aspect of the present invention, in the agricultural machine according to the second aspect, when shifting to the adjustment mode, the engine speed is reduced to an idling state, and when returning to the original mode before the transition. The engine speed is returned to the rated speed.

  According to the present invention, when the clutch operating means for switching off the power transmission from the engine to each operating part is operated, the adjustment for adjusting the function of each operating part from the other modes being executed is performed. Since the mode is shifted to display the information on the adjustment mode on the display means, the function adjustment work is performed in accordance with the screen display of the display means after the power transmission to the operating parts is interrupted. That is, since the disengagement operation of the clutch operating means is a trigger for shifting to the adjustment mode, there is an effect that safety in performing the function adjustment work can be reliably ensured.

  According to the invention of claim 2, when the clutch operating means is entered and operated during execution of the adjustment mode, the adjustment mode returns to the original mode before the transition, and the screen display of the display means is Since the transition from the information of the adjustment mode to the information of the original mode, it is possible to smoothly return to normal work (running on the road or various farming work) only by the operation of entering the clutch operation means, and the operation load of the operator can be reduced. Play.

  According to the invention of claim 3, when shifting to the adjustment mode, the rotational speed of the engine is reduced to an idling state, and when returning to the original mode before the transition, the rotational speed of the engine is set to the rated speed. The engine speed can be changed to an appropriate state (rated state, idling state, etc.) along with the on / off operation of the clutch that interrupts power transmission to each operating part. This has the effect of preventing waste of fuel and saving energy consumption.

After being cut short by the waste cutter 56, it is discharged out of the machine.

(2). Structure for Adjusting Grain Selection Performance Next, a structure for adjusting the grain selection performance by the chaff sheave 41 and the red pepper fan 33 of the swing sorter 32 will be described with reference to FIGS. 3 and 4. To do.

  The chaff sheave 41 manually adjusts the inclination angle of the first horizontal beam 61a, which will be described later, and the movable chaff part 61 configured to be automatically changeable in accordance with the amount of harvested cereal and the second horizontal beam 62a, which will be described later. A manual chaff portion 62 configured to be changeable in two stages by an operation and a fixed chaff portion 63 including a plurality of third horizontal bars 63a are provided. The movable chaff portion 61 is located above the grain sheave 42 (first flange 45). The manual chaff portion 62 is located above the second basket 46. The fixed chaff portion 63 is located behind the manual chaff portion 62.

  The movable chaff 61 is a chaff supported by a plurality of first horizontal bars 61a that are inclined to the front and downward and obliquely upward (backward and obliquely upward) as viewed from the side, and the left and right side plates of the swing sorter 32 so as to be movable back and forth. And an adjustment rod 61b. The upper end side of each first horizontal bar 61a is rotatably connected to the left and right side plates of the swing sorter 32, while the lower end side is rotatably connected to the chaff adjusting rod 61b. For this reason, the inclination angle of each first crosspiece 61a is changed all at once by the back-and-forth movement of the chaff adjusting rod 61b. As a result, the leakage interval (opening / closing degree of the movable chaff portion 61) between the first horizontal bars 61a is widened or narrowed.

  The chaff adjusting rod 61b is configured to move back and forth by the action of an interlocking link mechanism 64 (see FIG. 4) arranged on the outer surface side of the left side plate in the threshing housing 30. The interlocking link mechanism 64 is interlocked and connected to the selection adjusting lever 17 disposed in the control unit 9 via the operation wire 65. As the sorting adjustment lever 17 is tilted upward, the chaff adjustment rod 61b moves rearward due to the action of the interlocking link mechanism 64 via the operation wire 65, and the leakage interval between the first horizontal bars 61a. The opening degree of the movable chaff portion 61 is configured to be widened. Here, the sorting adjustment lever 17 can be tilted in five stages from the bottom to the top. The opening / closing degree of the movable chaff part 61 is the smallest (narrow) in the first stage tilted to the bottom, and the opening / closing degree of the movable chaff part 61 is the largest (wide) in the fifth stage tilted to the top. .

  Although not shown in detail, the interlocking link mechanism 64 is also interlocked with a chain guide for holding the stocker of the waste together with the waste chain 55 via a linkage wire 66 different from the operation wire 65. It is connected. As the chain guide moves away from the waste chain 55 to increase the amount of waste, the chaff adjusting rod 61b moves rearward due to the action of the interlocking link mechanism 64 via the linkage wire 66, and each first horizontal rail is moved. The leakage interval between 61a (opening / closing degree of the movable chaff part 61) is configured to be widened.

  The manual chaff portion 62 basically has the same configuration as the movable chaff portion 61, and a plurality of second horizontal bars 62 a that are longitudinally inclined to the front obliquely downward (backward obliquely upward) in a side view, and the swing sorter 32. And a chaff changing rod 62b supported by the left and right side plates so as to be movable back and forth. The upper end side of each second horizontal bar 62a is rotatably connected to the left and right side plates of the swing sorter 32, while the lower end side is rotatably connected to the chaff changing rod 62b.

  The chaff changing rod 62b is provided with a chaff adjusting lever 67 for manually moving the chaff changing rod 62b to the front position and the rear position. By moving the chaff changing rod 62b to the front position or the rear position by manual operation of the chaff adjusting lever 67, the inclination angles of the second horizontal bars 62a are changed all at once, and the opening / closing degree of the manual chaff portion 62 is closed. The state is changed into three stages of a normal state, an open state, and an open state. The chaff adjusting lever 67 faces a viewing window hole 68 formed on the rear side of the left side plate in the threshing housing 30 (the rear portion of the manual chaff portion 62). It goes without saying that the viewing window hole 68 is closed by a door (not shown) so as to be opened and closed.

  As described above, the fixed chaff portion 63 is composed of a plurality of left and right third horizontal bars 63a that are inclined obliquely forward and downward (backward and obliquely upward) in a side view. Each of these third horizontal bars 63a is fixed to the left and right side plates of the swing sorter 32 so as not to move.

  On the other hand, an air intake 69 is formed on the front side of the left side plate in the threshing housing 30 (location of the Chinese fan 33). A fan shutter 70 for increasing or decreasing the opening area of the air intake port 69 is provided on the upper side of the air intake port 69. The fan shutter 70 is provided with an opening / closing lever 71 for manually opening / closing the fan shutter 70. In this case, when the fan shutter 70 is opened and closed by manual operation of the opening / closing lever 71, the amount of the selected air from the hot fan 33 is increased or decreased.

(3). Next, the power transmission system of the combine will be described with reference to FIG.

  One of the motive power from the engine 20 is branched and transmitted in two directions of the reaping device 3 and the threshing device 5. Other power from the engine 20 is transmitted toward the discharge auger 8. The branching power from the engine 20 toward the reaping device 3 is once transmitted to the HST input shaft 102 of the hydraulic pump hydraulic motor type (HST type) continuously variable transmission in the transmission case 21 via the reaping clutch 101 and is appropriately shifted. The The speed change output by the continuously variable transmission is transmitted from a cutting PTO shaft 103 projecting from the transmission case 21 through a pulley and a belt transmission system to a horizontal transmission input shaft 104 and a vertical transmission housed in the cutting frame 22. The power is transmitted to the shaft 105, and the power is transmitted from the cutting input shaft 104 and the vertical transmission shaft 105 to the devices 23 to 25 of the cutting device 3.

  On the other hand, the branching power from the engine 20 toward the threshing device 5 is transmitted to the threshing input shaft 107 via the threshing clutch 106. A part of the power transmitted to the threshing input shaft 107 is transmitted to the rotating shaft 110 of the processing cylinder 34, the rotating shaft 109 of the handling cylinder 31, and the waste chain 55 via the threshing drive mechanism 108. Further, from the threshing input shaft 107, the fan shaft 111 of the Kara fan 33, the first conveyor 43 and the cereal conveyor 51, the second conveyor 44, the reduction conveyor 53, and the second reduction processing cylinder via a pulley and a belt transmission system. 54, the rocking crankshaft 37 of the rocking sorter 32, the dust removing shaft 112 of the dust fan 35, and the waste cutter 56. The branching power via the dust removal shaft 112 is transmitted to the feed chain 6 via the FC (feed chain) clutch 113 and the FC (feed chain) shaft 114.

  The power from the threshing input shaft 107 can also be transmitted to the cutting input shaft 104 via the pouring clutch 115. That is, by directly transmitting the power from the engine 20 to the reaping device 3 without going through the mission case 21, the reaping device 3 can be forcibly driven at a constant high speed regardless of whether the vehicle speed is fast or slow. It has become.

  The power from the engine 20 toward the discharge auger 8 is transmitted through a glen input gear mechanism 116 and a power interrupting auger clutch 117 to a bottom conveyor 118 in the glen tank 7 and a vertical conveyor 119 in a vertical auger cylinder in the discharge auger 8. Then, the power is transmitted to the discharge conveyor 121 in the horizontal auger cylinder of the discharge auger 8 via the transfer screw 120.

(4). Details of Mode Switching Control Next, details of the mode switching control in the combine will be described with reference to FIGS.

  The controller 130 as the control means mounted on the traveling machine body 1 is for controlling the overall operation of the combine, and for executing the mode switching control and the display control of the liquid crystal display 75. As shown in FIG. 6, the controller 130 includes a CPU 131 that executes various arithmetic processes and controls, an EEPROM 132 as a storage unit that stores control programs and data, a RAM 133 that temporarily stores control programs and data, And an input / output interface (not shown).

  The EEPROM 132 serving as a storage means stores in advance various information such as characters, symbols, and images relating to the combine mode (operation state). Although details will be described later, this type of information includes, for example, normal mode information 140 (see FIG. 7), adjustment mode selection menu information 150 (see FIG. 8), and each operating part of the combine (threshing device 5 and traveling device 2). And the like, and guidance information 170 (see FIGS. 10 to 12) indicating an adjustment method for eliminating the inconvenient state. The EEPROM 132 also stores data related to the rated speed and idling speed of the engine 20 in advance.

  The input interface of the controller 130 includes a rack position sensor 134 for detecting the rack position of a fuel injection pump (not shown) with a governor for adjusting the fuel injection amount to the engine 20, and a cutting for detecting the operating state of the cutting clutch 101. A clutch sensor 135, a threshing clutch sensor 136 for detecting an operating state of the threshing clutch 106, a touch panel 76 as an input means, and the like are connected. The output interface of the controller 130 includes a rack actuator 137 for adjusting the rack position of the fuel injection pump so that the rotational speed of the engine 20 is set to a predetermined rotational speed, a reaping drive circuit 138 for driving the reaping actuator, and threshing A threshing drive circuit 139 for driving the actuator, a liquid crystal display 75 as a display means, and the like are connected.

  The combine mode (operation state) includes an initial mode, a normal mode for running on the road and various farming operations, an alarm display mode for notifying the abnormal state of each operating unit in the combine, and an error for notifying the contents of various errors. There are a display mode, an environment setting mode, and an adjustment mode in which guidance information 170 (details will be described later) indicating the adjustment method is displayed on the liquid crystal display 75 when adjusting the function of each operating unit.

  The normal mode is executed when running on the road or performing various farming operations. In this case, on the liquid crystal display 75, as the normal mode information 140, a speedometer 141 indicating the traveling speed (vehicle speed) of the traveling machine body 1, a substantially L-shaped load graph 142 indicating the engine load, and soot storage in the Glen tank 7 A tank monitor 143 that informs the amount, a fuel gauge 144 that informs the remaining amount of fuel, a sub-transmission monitor 145 that informs the setting state of the sub-transmission lever 14, a cutting shift monitor 146 that informs the setting state of the driving speed in the trimming device 3, and adjustment A “Help” button 147 for shifting to the mode is displayed (see FIG. 7).

  When the “Help” button 147 is pressed during execution of the normal mode, the mode is changed from the normal mode to the adjustment mode, and the screen display on the liquid crystal display 75 changes from the normal mode information 140 to the adjustment mode selection menu information 150 (see FIG. 8). Transition. On the screen of the selection menu information 150 shown in FIG. 8, there is character data 151 of “Is there a bad place?” And “reaping device”, “threshing device”, “traveling device” indicating the operation part to be adjusted. ”,“ Auger ”and“ Exclusion ”are displayed, and a“ Return ”button 157 for returning to the normal mode is displayed.

  In the first embodiment, when shifting from the normal mode to the adjustment mode by pressing the “help” button 147, the cutting clutch 101 and the threshing are driven by driving the cutting and threshing actuators based on a command from the controller 130. The clutch 106 is disengaged. Then, by driving the rack actuator 137, the rack of the fuel injection pump with a governor is moved to a position corresponding to the idling speed data, so that the speed of the engine 20 is lowered to an idling state.

  If control is performed in this way, and there is some malfunction in any operating part and it is desired to adjust the function, the chopping clutch 101 and the threshing clutch 106 can be switched off simply by pressing the “Help” button 147 and executing the adjustment mode. The power transmission to each operation part can be interrupted. Therefore, it is possible to save time and effort to turn off the clutch lever 15 when adjusting the function of each operating part, and even if the operator performs the function adjusting work without forgetting to turn off the clutch lever 15, the operating part to be adjusted is driven. No, function adjustment work can be performed very safely (safety for function adjustment work can be ensured).

  In particular, in the first embodiment, a hydraulic pump hydraulic motor type continuously variable transmission for driving the traveling crawler 2 is provided on the downstream side of the power transmission with respect to the cutting clutch 101, so if the adjustment mode is being executed, Even if the operator inadvertently hits the main transmission lever 13 or the like, the combine does not start to move.

Then, by driving the pump actuator 257, the throttle valve of the carburetor is rotated to an angle corresponding to the rated rotational speed data stored in the EEPROM 252, so that the rotational speed of the engine 205 returns to the rated state. .

  By controlling in this way, if there is some malfunction in any operating part and it is desired to adjust the function, the planting clutch is disengaged by operating the planting operation lever 218 in a neutral state and the adjustment mode is changed from the normal mode to the adjustment mode. Then, the adjustment mode information can be displayed on the liquid crystal display 215. For this reason, since the planting clutch is disengaged and the power transmission to the seedling planting device 224 is interrupted, the function adjustment work is performed according to the screen display of the liquid crystal display 215. Similarly, safety in performing the function adjustment work can be reliably ensured.

  In addition, since the rotational speed of the engine 205 is lowered to the idling state together with the disengagement operation of the planting clutch, there is an advantage that waste of fuel can be prevented and energy consumption can be saved.

  Further, by operating the planting operation lever 218 to a position other than the neutral position, the planting clutch is brought into the engaged state, and the normal mode before the transition is returned from the adjustment mode, and the screen display of the liquid crystal display 215 is displayed. In addition to returning to the original normal mode information 260, the engine 205 is returned to the rated speed so that only normal operations (running on the road and various farming operations) can be performed simply by operating the planting control lever 218 to a position other than neutral. Therefore, the operation burden on the operator can be reduced.

(10). Details of Mode Switching Control Next, details of mode switching control in the tractor will be described with reference to FIGS. 29 to 35.

  A controller 350 as a control means mounted on the traveling machine body 301 controls the overall operation of the tractor, and executes mode switching control and display control of the liquid crystal display 340. As shown in FIG. 29, the basic configuration of the controller 350 is the same as that of the first and second embodiments, and includes a CPU 351, an EEPROM 352 as a storage means, a RAM 353, an input / output interface (not shown), and the like. .

  In the EEPROM 352, various types of information such as characters, symbols, and images relating to the tractor mode (operation state) are stored in advance. Although details will be described later, this type of information includes, for example, normal mode information 360 (see FIG. 30), adjustment mode selection menu information 370 (see FIG. 31), each operating part of the tractor (cultivator 302, traveling device, etc.) ) (See FIG. 32), and guidance information 390 (see FIGS. 33 and 34) showing an adjustment method for eliminating the inconvenient state. The EEPROM 352 also stores data related to the rated rotational speed and idling rotational speed of the engine 305 in advance.

  The input interface of the controller 350 includes a rack position sensor 354 for detecting a rack position of a fuel injection pump (not shown) with a governor for adjusting the fuel injection amount to the engine 305, and an operation of a PTO clutch in the mission case 316. A PTO clutch sensor 355 for detecting a state, a touch panel 341, and the like are connected. The output interface of the controller 350 includes a rack actuator 357 for adjusting the rack position of the fuel injection pump to set the rotation speed of the engine 305 to a predetermined rotation speed, a PTO drive circuit 258 for the PTO actuator, a liquid crystal display 340, etc. Is connected.

  The tractor mode (operational state) includes an initial mode, a normal mode for running on the road and various farming operations, and guidance information 390 indicating the adjustment method when adjusting the function of each operating unit. There are adjustment modes and the like displayed on 340.

  The normal mode is executed when running on the road or performing various farming operations. In this case, on the liquid crystal display 340, as the normal mode information 360, a speedometer 361 indicating the traveling speed of the traveling machine body 301, a substantially L-shaped load graph 362 indicating the engine load, a fuel meter 364 notifying the remaining amount of fuel, Then, a “help” button 367 for shifting to the adjustment mode is displayed (see FIG. 30).

  When the “Help” button 367 is pressed during execution of the normal mode, the mode is changed from the normal mode to the adjustment mode, and the screen display of the liquid crystal display 340 changes from the normal mode information 360 to the adjustment mode selection menu information 370 (see FIG. 31). Transition. In the screen of the selection menu information 370 shown in FIG. 31, character data 371 “Is there a bad place?” And “traveling device”, “work machine”, and “others” indicating the operation unit to be adjusted are displayed. Are displayed, and a “Return” button 377 for returning to the normal mode.

  In the third embodiment, when the “Help” button 367 is pressed to shift from the normal mode to the adjustment mode, the PTO clutch is disengaged by driving the PTO actuator based on a command from the controller 350. Then, by driving the rack actuator 357, the rack of the fuel injection pump with governor is moved to a position corresponding to the data on the idling speed, so that the speed of the engine 305 is lowered to the idling state.

  As described above, in the case of the third embodiment as well, if there is some malfunction in any operating part and it is desired to adjust the function, simply press the “Help” button 367 to execute the adjustment mode and disconnect the PTO clutch. The power transmission to the cultivator 302 can be cut off by operating. Therefore, even if the operator performs the function adjustment work while leaving the PTO shift lever 348 neutral, the cultivator 302 is not driven, and the function adjustment work can be executed very safely (in the function adjustment work). To ensure safety). Moreover, since the rotational speed of the engine 305 is lowered to the idling state together with the PTO clutch disengagement operation, waste of fuel can be prevented and energy consumption can be saved.

  When the “return” button 377 is pressed while the selection menu information 370 is displayed on the liquid crystal display 340, the adjustment mode is changed to the original normal mode, and the screen display of the liquid crystal display 340 returns to the original normal mode information 360. At this time, by driving the rack actuator 357 based on a command from the controller 350, the speed of the engine 305 is set to the rated state by moving the rack of the fuel injection pump with the governor to a position corresponding to the rated speed data. Return to.

  In addition, when the selection menu information 370 is displayed on the liquid crystal display 340 after shifting to the adjustment mode and the touch panel 341 is not touched (not operated) for a predetermined time, the adjustment mode returns to the original normal mode before the transition. Then, the screen display of the liquid crystal display 340 returns to the original normal mode information 360. When the PTO clutch is disengaged in conjunction with the mode switching, it is desirable to automatically move the PTO speed change lever 348 to the neutral position by driving a lever actuator (not shown).

  For example, when there is some trouble in the cultivator 302 and the function adjustment is desired, the selection button 373 of “work machine” is pressed while the selection menu information 370 of FIG. 31 is displayed on the liquid crystal display 340. Then, the work implement (the cultivator 302 in the third embodiment) is selected (determined), and the screen display of the liquid crystal display 340 changes from the selection menu information 370 to the work implement inconvenient state information 380 (see FIG. 32). ). On the screen of the inconvenient state information 380 shown in FIG. 32, question data 381 (character data such as “work machine is tilted?”) Indicating a specific inconvenient state, a “Yes” button 382, and “No” "Button 383 and a" return "button 384 for returning the screen display of the liquid crystal display 340 to the selection menu information 370.

  When the “Yes” button 382 is pressed while the inconvenient state information 380 of FIG. 32 is displayed on the liquid crystal display 340, the selected inconvenient state information 380 (question data 381 of “work machine is tilted?”) Is canceled. Guidance information 390 indicating the adjustment method is switched and displayed on the liquid crystal display 340 (see FIGS. 33 and 34). The inconvenient state information 390 screen shown in FIGS. 33 and 34 includes answer data 391 that represents a specific adjustment method, caution data 392 that indicates precautions for function adjustment, an “OK” button 393, and “ Next "button 394 is displayed.

  Settings related to the guidance information 390 and the “next” button 394 are basically the same as those in the first and second embodiments. There are two pieces of guidance information 390 (answer data 391) for the inconvenience state information 380 (question data 381) of “work machine is tilted?”. In the following description and FIGS. 33 and 34, for convenience, the symbols a and b are assigned to the guidance information 390 (each answer data 391) for the question data 381 of “Is the work machine tilted?” In descending order of priority. May be attached.

  For example, when the “Yes” button 382 in FIG. 32 is pressed, the screen display of the liquid crystal display 340 transitions from the inconvenience state information 380 of the work implement to the guidance information 390a of the first priority (see FIG. 33). The answer data 391a of the first priority is character data “Adjust by turning the tilt setting dial one scale to the left or right”.

  Next, when the “Next” button 394 in FIG. 33 is pressed, the screen display of the liquid crystal display 340 transitions from the first priority guidance information 390a to the second priority guidance information 390b (see FIG. 34). . The answer data 391b with the second highest priority is character data “Please check whether the sensor wire attached to the hydraulic cylinder for rolling is caught”.

  By controlling in this way, if there is some malfunction in an arbitrary operation part and it is desired to adjust the function, the adjustment mode is executed by pressing the “Help” button 367 to display information on the adjustment mode on the liquid crystal display 340. Because it is possible to display guidance information 390 indicating the adjustment method according to the inconvenience, the operator can easily check the adjustment method without an instruction manual, and easily perform the function adjustment work according to the screen display of the liquid crystal display 340. it can.

  In addition, since the guidance information 390 having the highest priority is switched and displayed on the liquid crystal display 340 in order, the operator can confirm from the adjustment method having the highest priority (for example, the one having a high possibility of eliminating the inconvenient state) first. This makes it possible to improve the efficiency of the function adjustment work (can contribute to reducing the time loss that the inconvenience cannot be solved).

  When the guidance information 390 of FIGS. 33 and 34 is displayed on the liquid crystal display 340, as in the first and second embodiments, a part of the liquid crystal display 340 (below the guidance information 390) is subjected to function adjustment. Attention data 392 indicating the precautions is also displayed. The caution data 392 shown in FIG. 33 and FIG. 34 is the same regardless of the priority of the guidance information 390, as in the first and second embodiments. Please receive "character data. In this case as well, it is possible to notify the operator in advance of the conditions and the like that are the preconditions for the function adjustment work, so that confirmation can be promoted, so that the function adjustment work can be performed in an appropriate state.

  When the “OK” button 393 is pressed while the guidance information 390 of FIGS. 33 and 34 is displayed on the liquid crystal display 340, the screen display of the liquid crystal display 340 returns to the selection menu information 370 of FIG.

  When the “next” button 394 is pressed while the second priority (lowest) guidance information 390b in FIG. 34 is displayed on the liquid crystal display 340, the screen display of the liquid crystal display 340 is the second priority guidance information. Transition from 390b to final treatment information 395 (see FIG. 35). The final treatment information 395 indicates a coping method when the malfunction state is not resolved even if the function adjustment is performed according to the two guidance information 390a and 390b, and the content is notified to a store or a service center. It encourages you to have a professional diagnosis. The final treatment information 395 screen shown in FIG. 35 displays character data 396 of “Please contact the store where you purchased the product if it is not resolved by the above operation” and an “OK” button 397. The

  Even with such control, it is easy to determine how much the current inconvenience is, that is, whether the operator can make adjustments on his own, or whether he / she has to ask an expert diagnosis. I can grasp. For this reason, depending on the current inconvenience, the operator himself can adjust the function without having to call an expert from the dealer or service center, and the farming work can be avoided.

  When the “OK” button 397 is pressed while the final treatment information 395 of FIG. 35 is displayed on the liquid crystal display 340, the screen display of the liquid crystal display 340 returns to the selection menu information 370 of FIG. In addition, it cannot be overemphasized that the above display control can be similarly performed regarding other operation parts other than a working machine (cultivator 302).

Another Example of Mode Switching Control In the third embodiment, when the PTO clutch lever 348 as the clutch operating means is operated to the neutral position and the PTO clutch is disengaged (power cutoff state) during execution of the normal mode. In response to a command from the controller 350, the normal mode is changed to the adjustment mode, and the screen display of the liquid crystal display 340 changes from the normal mode information 360 to the adjustment mode selection menu information 370 (see FIG. 31). Then, by driving the rack actuator 357, the rack of the fuel injection pump with governor is moved to a position corresponding to the data on the idling speed, so that the speed of the engine 305 is lowered to the idling state.

  On the other hand, if the PTO shift lever 348 is operated to a position other than neutral while the adjustment mode is being executed to bring the PTO clutch into the engaged state (power connection state), the command from the controller 350 before the transition from the adjustment mode is made. And the screen display of the liquid crystal display 340 returns to the original normal mode information 360. Then, by driving the rack actuator 357, the speed of the engine 305 is returned to the rated state by moving the rack of the fuel injection pump with a governor to a position corresponding to the data of the rated speed.

  By controlling in this way, if there is any malfunction in any operating part and it is desired to adjust the function, the PTO clutch is disengaged by moving the PTO shift lever 348 to neutral and the normal mode is switched to the adjustment mode. Thus, the adjustment mode information can be displayed on the liquid crystal display 340. For this reason, the function adjustment work is performed according to the screen display of the liquid crystal display 340 after the power transmission to the working machine (cultivator 302) is cut off with the PTO clutch disengaged, so the first and second implementations As in the case of the example, safety in performing the function adjustment work can be reliably ensured.

  In addition, since the rotational speed of the engine 305 is lowered to the idling state together with the PTO clutch disengagement operation, there is an advantage that waste of fuel can be prevented and energy consumption can be saved.

  Further, by operating the PTO shift lever 348 to a position other than the neutral position, the PTO clutch is brought into the engaged state, and the normal mode before the transition is restored from the adjustment mode, and the screen display of the liquid crystal display 340 is restored to the original state. In addition to returning to the normal mode information 360, the engine 305 speed is returned to the rated speed so that the operation can be smoothly shifted to normal work (road driving and various farm work) only by the operation other than neutral of the PTO shift lever 348. Therefore, the operation burden on the operator can be reduced.
