Abstract
An engine control system includes an engine with an output shaft. A power take-off device interfaces with the output shaft and provides rotational power to an auxiliary device. A user input device includes a first engine speed control that commands an increase in engine speed by a first amount to increase the rotational power to the auxiliary device when a user selects the first engine speed control. A second engine speed control commands an increase in engine speed by a second amount that is greater than the first amount to increase the rotational power to the auxiliary device when the user selects the second engine speed control. The user input device includes a speed cancellation control that commands a reversal of a net increase in the speed of the engine that is commanded via the user input device when the user selects the speed cancellation control.
