A control for limiting the torque output of an engine when operating in a PTO mode is provided. The control includes a microprocessor connected to a PTO on/off switch, a set/resume switch and a torque limit on/off switch. When the torque limit switch is in an on position, the microprocessor limits the maximum torque output to an operator programmed value. The operator can reprogram the torque limit value with a programming tool.
