Abstract

PURPOSE: To simplify the transmission operation by controlling oil flow of the transmission gear with an electric switch.
CONSTITUTION: This farm machine is equipped with a hydraulic circuit composed of a transmission gear PS including 5-port 3-position switching and 4-port 3-position switching electromagnetic direction valves VA and Vb and a hydraulic multiplate clutch and an electric circuit to control the oil flow of the transmission gear PS with a switching element. By the switching operation of the electric circuit, solenoids S1 to S3 and SR are excited to switch the oil flow supply circuit to the transmission gear. In this manner, when a transmission command is given to shift the position from the advance to retraction, the transmission can be made to retract via the neutral position. This transmission enables shift to the traction once after the machine is halted, thereby improving confortability eliminating impact on operators.
