Abstract
A preferred embodiment of the present invention includes a power take off ('PTO') controller used on a vehicle. The controller includes a PTO on/off switch, a brake/clutch ignore switch, and a PTO set/resume switch connected to an electronic controller. The controller sets the engine speed command to a PTO default speed in response to the PTO on/off switch being in an on position. By placing the brake/clutch ignore switch in an ignore position, the vehicle operator can use the brake or clutch without affecting the PTO engine speed.
