DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawings show an embodiment of the present invention. A tractor is used as a traveling vehicle body a, and a frame 2 having a hydraulic system for mowing and cultivating work is attached to the rear side of the traveling vehicle body a. In the case where a working machine body b having a height lower than that of the traveling vehicle body a and having four free wheels 3 hung vertically is attached via a protrusion adjusting mechanism 1 capable of adjusting the lateral protrusion degree. Is illustrated.

A mast 5 is provided on the frame 2, and a swivel holding cylinder 6 which can be horizontally rotated about the mast 5 is fitted and fixed to the mast 5, and the right side of the swivel holding cylinder 6 (FIG. 3) is fixed. The base end of the outer corner cylinder 7 of the protrusion adjusting mechanism 1 is pivotally attached to the bearing portion 6a, and the rotating link 9 of the rotating mechanism 8 for rotating the working machine body b in the vertical direction is attached to the bearing portion 6b on the left side (FIG. 3). Pivot the base end,
The base of a rotary cylinder 10 is pivotally attached to the other end 9'of the rotary link 9, and the tip of a piston rod 10 'of the rotary cylinder 10 is attached to the upper end of the outer corner cylinder 7 of the protrusion adjusting mechanism 1. It is pivotally attached to the locking piece 7 '.

Inside the outer corner tube 7 of the protrusion adjusting mechanism 1, an inner corner tube 11 having a connecting arm rod 12 for suspending and holding the working machine body b connected at the other end is slidably inserted into the inner corner tube 11. A protrusion adjusting cylinder 13 is attached to the inside of the bearing, and the base end of the protrusion adjusting cylinder 13 is attached to the bearing 6a.
This adjustment cylinder is pivotally attached to the inside of the closing wall of the outer square cylinder 7 on the side of
The end of the piston rod 13 'of 13 is pivotally attached to the inside of the closing wall on the right side (FIG. 3) of the inner rectangular tube 11.

In the figure, reference numeral 14 is a lift operation lever for operating the rotary cylinder 10 of the rotary mechanism 8, 15 is an offset operation lever for operating the protrusion adjusting cylinder 13 of the protrusion adjusting mechanism 1, and 16 is a working machine body. The working machine control lever 17 for operating the rotary b is an oil tank.

When the hydraulic pump 18 is operated by the power input from the power take-out port (PTO) of the traveling vehicle body a via the power transmission shaft 4 and the lift operation lever 14 is tilted backward to operate the hydraulic pressure, the rotary cylinder is rotated. The piston rod 10 ′ of 10 extends and the tip of the outer square cylinder 7 rotates downward by the link mechanism with the bearing portion 6 a of the swivel holding cylinder 6 as a fulcrum, and the inner square cylinder 11 and the inner square cylinder 11 fitted in the outer square cylinder 7 are inserted. Similarly, since the connecting arm rod 12 continuously connected to the lower arm rotates downward and the free wheel 3 of the working machine body b abuts on the ground, when the hand is lifted from the lift operation lever 14 at that position, the lever is in the neutral position. It automatically returns to and the working machine b is installed on the ground.

The working machine operating lever 16 is tilted backward to operate the rotary of the working machine for mowing and tilling work, and the traveling vehicle body a
To move forward, and perform work such as mowing and plowing in fields under the crown of orchards.

When it is discovered that the working machine body b may come into contact with or abut on a tree trunk or an obstacle during traveling, if the offset operating lever 15 is tilted rearward at an appropriate position immediately before the obstacle, the protrusion adjusting mechanism 1 can be operated. The piston rod 13 ′ of the protrusion adjusting cylinder 13 provided inside the inner corner cylinder 11 contracts, the lateral protrusion of the connecting arm body 12 connected to this contracts, and the working machine body b travels. It is possible to prevent the working machine body b from coming into contact with the tree trunk and obstacles because the working machine body b comes close to.

At this time, since the working machine body b is provided with four freely movable wheels 3 which can easily turn around in the traveling direction, the degree of lateral projection of the working machine body b is adjusted. The working machine body b can be laterally moved by freely following the movement of the protrusion adjusting cylinder 13. Further, at this time, the outer square cylinder 7 in which the inner square cylinder 11 is fitted is slightly rotated upward with the bearing portion 6a of the swivel holding cylinder 6 as a fulcrum as the protrusion degree is adjusted. The tip 9'of the moving link 9 is absorbed by rotating around the bearing portion 6a of the swivel holding cylinder 6 as a fulcrum.

When the working machine body b has passed the trunk or obstacle, the offset operating lever 15 is tilted forward again to extend the piston rod 13 'of the protrusion adjusting cylinder 13 of the protrusion adjusting mechanism 1,
By the operation opposite to the above, the degree of protrusion of the actuator body b with respect to the traveling vehicle body a is restored to continue mowing and plow work.

Reference numeral 19 in the figure is an oil motor for operating the actuator.
