<p>PURPOSE:To stop transmitting motive power to a working machine during its movement on the road, by using a single lever to change the speed of the movement and operate the clutch of the machine. CONSTITUTION:The moving transmission mechanism 7, forward/backward changeover mechanism 8 and clutch 9 of a working machine are operated by a lever 10. A guide 11 for the lever 10 comprises a rapid moving part H, a slow moving part L and a backward moving part R. Only the slow moving part L is located at the right side of the guide. For that reason an engaging member 17 is operated only when the lever 10 is located in the slow moving part L. Only at that time, motive power is transmitted to the working machine. According to this constitution, the machine does not work during its road movement or the like. Safety is thus heightened.</p> |
