SPEED CHANGE MECHANISM FOR WORK VEHICLE

摘要

A working vehicle provided with a hydraulic continuously variable transmission, has a plurality of wheels; a vehicle body supported by the plurality of wheels; a hydraulic continuously variable transmission that is supported by the vehicle body, and that has a speed change actuation shaft; a speed change pedal operatively linked to the speed change actuation shaft for controlling the speed change actuation shaft; and a neutral bias mechanism for biasing the speed change actuation shaft toward a neutral position. The bias mechanism includes a cam portion that pivots together with the speed change actuation shaft; an operation member that abuts against the cam portion; and a biasing means for biasing the operation member toward the cam portion. The biasing means is disposed above a step surface of a riding step.
