SPEED CONTROL MECHANISM FOR WORK VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide safety in traveling when a brake pedal is disconnected. SOLUTION: In a work vehicle, the brake pedal 17 is composed of a left pedal 17L and a right pedal 17L, and these pedals are composed to be connectable by a connection plate 88. A brake disconnection switch 50 to detect disconnection of the brake pedal 17 is connected to a controller 110 to control an HST 23. By controlling a rotation range of a trunnion shaft 61, traveling speed when the brake pedal 17 is disconnected is regulated.
