Abstract

An emergency stop brake operation assembly necessary for a work vehicle when travelling autonomously in an unmanned state is provided in this brake system without introducing problems to manual driving of the work vehicle by an occupant. This brake system for work vehicles comprises: a brake pedal that is disposed in a driving section; a brake that brakes left and right rear wheels; a linkage mechanism that links the brake pedal and the brake in such a manner as to allow the brake pedal and the brake to operate in conjunction with each other; and an electric brake operating device that actuates the brake in response to an emergency stop command. The brake operating device has: an operation-receiving body that is coupled to the brake pedal; an electric actuator that operates the operation-receiving body; and a clearance-provided section which is located between the brake pedal and the electric actuator and allows displacement of the brake pedal and the linkage mechanism with respect to the electric actuator when the brake pedal is depressed.
