Abstract

PURPOSE: To attempt to secure the shrinkage of the turning radius and secure the stable traveling of the subject tractor by utilizing a simple lever operation consisting only of a working machine lifting operation at the time of turning to make it possible to interrupt a front wheel drive hydraulic clutch through a limit switch.
CONSTITUTION: In the agricultural tractor, the motive power of an engine is transmitted to front and rear gears through a suitable speed change device. At the lower part of a mission case 4, there is provided a drive shaft 6 connected to a gear group of a front gear case (not shown). At the base portion of the shaft 6, there is provided a hydraulic clutch 8 for front-wheel drive. At the time of turning on the side of a ridge, when a lever 18 for lifting and lowering operations is rotated to "a lifting position" (chain-line position), the constantly opened contact of a limit switch 15 is closed, and a current is caused to flow through a solenoid 14. By these procedures, an electromagnetic valve 9 is changed over, and compressed oil within a hydraulic tank 11 is supplied to a hydraulic clutch 8, and interrupts the clutch 8 to cut off the transmission of the motive power to the front wheel.
