Abstract:
PROBLEM TO BE SOLVED: To provide a configuration capable of adjusting a deceleration in response to an operator's intention in a work vehicle including a hydraulic continuously variable transmission.SOLUTION: A tractor (work vehicle) comprises: an engine; a hydraulic continuously variable transmission; a travel unit; a depression amount detector; and a control unit. The hydraulic continuously variable transmission changes gears to transmit an output of the engine. The travel unit travels a vehicle body by an output from the continuously variable transmission. The depression amount detector detects a depression amount of a brake pedal. The control unit reduces a vehicle velocity by controlling an HMT at a deceleration calculated to become higher as the depression amount is larger on the basis of the depression amount detected by the depression amount detector.
