Abstract
PURPOSE: To prevent the breakdown of an engine by obstructing speed change operation to low speed from high speed of an auxiliary transmission when the speed of revolution of the engine is not less than a fixed value.
CONSTITUTION: A driving device is formed to ensure that a speed change signal generating circuit 274 does not generate speed change signals when the signals of a revolution speed detecting circuit 260 is not less than a fixed value and the signals of a speed change location by a speed change location detecting circuit 254 of the auxiliary transmission are high speed. Thus, when the speed of revolution of an engine is not less than a fixed value, the speed of revolution does not exceed the allowable speed of revolution of the engine even by the increase of the speed of revolution of the engine generated by speed change operation to low speed from high speed of the auxiliary transmission because the speed change operation of low speed from high speed of the auxiliary transmission is obstructed, and the breakdown of the engine can be prevented effectively.
