SPEED CHANGE OPERATION DEVICE FOR WORKING VEHICLE

摘要

PROBLEM TO BE SOLVED: To solve the problem on a tractor having a throttle lever and a hydromechanical transmission (HMT) which can maintain stable speed and loading work during low speed working travel that engine stop occurs due to lack of the revolving output of an engine or the need for troublesome work exists in resetting the throttle lever to a high revolution side when a speed change pedal is actuated for high speed operation.

SOLUTION: The output speed of the HMT is varied by the actuation of the speed change pedal 5. A thrust accelerating operation part 6 is provided on the lower face of the speed change pedal 5 for increasing/reducing the output speed of the engine set and held by the throttle lever 4 at the same time when the pedal is actuated.
