Abstract

PURPOSE: To prevent abnormal travelling such as quick pitching of the machine body in the shifting of manual to automatic operation by means of a mechanism adapted to automatically detect and memorize the speed of the change gear as the upper limit speed for controlling the automatic operation mechanism.
CONSTITUTION: A manual operation mechanism A is composed of an output rotational frequency control lever 7a and a speed control lever 9 connected by means of a link mechanism 10. On the other hand, the automatic operation mechanism B is so arranged that the detection signal from a mechanism 15 for detecting the position of the lever 9 and the running speed and a hulling load detection mechanism 19 is applied on a controller 17 for motor 12 to properly control the speed. Here, mechanism 21 is provided to automatically detect and memorize as the upper limit speed of the operation mechanism the speed immediately when a switching is made from the manual to automatic operation of the change gear 7. Thus, work including reaping is doen with the speed detected as the upper limit.
