摘要： A rotating rate control apparatus for adjusting rotation of an engine of a working vehicle between a minimum rate and a maximum rate. The control apparatus has a first, a second and a third rotating rate adjusting devices. The first rotating rate adjusting device adjusts a basic rotating rate of the engine between the minimum rate and maximum rate. The second rotating rate adjusting device is shiftable between an ON position and an OFF position. The second rotating rate adjusting device is operable, when in the ON position, to set the engine to a predetermined rotating rate between the minimum rate and the maximum rate inclusive. The third rotating rate adjusting device is operable, when the second rotating rate adjusting device is in the OFF position, to adjust the rotating rate of the engine between the basic rotating rate adjusted by the first rotating rate adjusting device and the maximum rate.

摘要： An interlock circuit for a working vehicle having a vehicle body, a working implement attached to the vehicle body, a clutch mechanism for connecting and disconnecting power to the working implement, and a shifting device for determining a traveling direction of the vehicle body. The interlock circuit has a check function to check a backward operational run in which the vehicle body travels backward with the clutch mechanism engaged, and a release function to permit a backward operational run by canceling the check function. The check function checks the backward operational run based on a signal indicating an on/off state of the clutch mechanism and a signal indicating a traveling direction of the vehicle body determined by the shifting device. The release function maintains the check function off continuously by operating a release switch when the clutch mechanism is engaged, and the signal indicating a traveling direction of the vehicle body indicates forward or neutral.
