PURPOSE:To make it possible to control a load lever while an accelerator pedal is left to be depressed upon gear shifting etc., by providing a lever control device comprising a cylinder and a piston between the load lever for controlling the supply amount of fuel for the engine and the accelerator pedal. CONSTITUTION:A load lever control device 18 comprising a stationary cylinder 26, a movable cylinder 28 and a piston 30 is disposed between a link 16A connected to an accelerator pedal and a link 16B connected to a load lever for controlling the supply amount of fuel for an engine. Fluid normally flows in a fluid chamber 29 in the movable cylinder 28 from a first fluid valve 34, resulting in that the accelerator and a lever are associated together. However, when a shift instruction is issued upon gear shifting, etc. so that first and second fluid valves 23, 36 are turned to its discharge side and its intake side, respectively, the coupling between the piston 30 and the movable cylinder 28 are disengaged, and therefore, the load lever may be controlled irrespective of the position of the accelerator in such a way that the supply amount of fuel is decreased to lower the rotational speed upon, for example, gear shifting. |
