Abstract:
1. A work vehicle comprising: a braking device including a rotating member that rotates together with an output shaft, a fixed member fixed to a vehicle body, and a brake piston, the braking device being configured and arranged to apply hydraulic pressure to the brake piston to control a pressing state between the rotating member and the fixed member such that a braking force is generated when the rotating member is pressed against the fixed member; a lubricant feeding section configured and arranged to feed a lubricant around the rotating member of the braking device so that the rotating member is cooled by the lubricant; and a controlling section configured to execute a first control in which an amount of the lubricant fed to the braking device is controlled based on a temperature of the rotating member, the controlling section being further configured to set the amount of the lubricant to a predetermined first feed amount when the braking device is in a braking state in which the rotating member and the fixed member are pressed against each other, and in the first control to calculate the temperature of the rotating member and to make a decision based on the calculated temperature of the rotating member to change the amount of the lubricant from the first feed amount to a second feed amount that is smaller than the first feed amount when the braking device is switched from the braking state to a non-braking state.
