ABSTRACT:
A speed control system for a working vehicle having a stepless change speed device and an auxiliary change speed device. The speed control system comprises a speed governor for controlling rotational rate of an engine, and an accelerator lever for operating the speed governor. The speed governor is interlocked with the stepless change speed device such that the rotational rate of the engine is increased with an accelerating operation of the stepless change speed device, and is decreased with a decelerating operation of the stepless change speed device. An interlock breaker is provided for breaking the interlocking between the speed governor and stepless change speed device when the auxiliary change speed device is in a low speed state.
