A vehicle such as a tractor having a rear mounted backhoe is provided with a mechanism for adjusting the speed of the engine to control the flow of fluid in the hydraulic control system. In addition to a conventional hand throttle, the mechanism for adjusting the engine speed includes an electric solenoid that can be actuated by a switch to increase the speed of the engine beyond the speed at which the hand throttle is set, and preferably to full throttle. This enables the operator of the vehicle to use the backhoe at an intermediate engine speed to perform backhoe functions that do not require maximum engine speed. By actuating a switch, the operator can quickly and easily increase the engine speed to full throttle to perform backhoe functions that require maximum engine speed.
