SPEED CONTROL FOR WORKING VEHICLE

摘要

A speed control device in a traveling work vehicle (1) changes a speed of rotational drive power from an engine to drive vehicle wheels and includes: a target speed calculator (62) determining a target speed, based on operation deflection of a speed change device (6B). A vehicle speed controller (67) adjusting a speed change ratio based on the target speed. A vehicle speed obtainer (6C) obtaining an actual vehicle speed. A forcible target speed modifier (63) forcibly modifying the target speed to a lower speed based on operation of a braking device (BD). A release (64) can treat an operation of the speed change device (6B) as a trigger to cancel the target speed forcibly modified by the forcible target speed modifier (63), and conforming the target speed to the actual vehicle speed.
