Abstract:
PROBLEM TO BE SOLVED: To solve a problem that a vehicle speed immediately before start of rotation operation in work tends to become unstable in a conventional work vehicle.SOLUTION: An agricultural tractor includes: a left brake pedal 510L; a right brake pedal 510R; a brake pedal coupling cancellation mechanism 700 cancelling coupling of the left brake pedal and right brake pedal; and a brake pedal coupling sensor 320 detecting a coupling state of the brake pedals. In tillage work machine lifting/lowering control, a tillage work machine 11 is not lifted/lowered when a detection value of a tillage depth sensor 310 is in a dead zone and a width of the dead zone in the tillage work machine lifting/lowering control is increased when cancelling of brake pedal coupling is detected by the brake pedal coupling sensor 320.SELECTED DRAWING: Figure 5
