Disclosed are horsepower management systems and methods for use on power machines with an engine that powers a drive system. An engine speed control device controls the engine speed. A variable displacement drive pump controlled by a displacement control member provides pressurized fluid to a drive motor. A control system communicates with the engine speed control device and the pump displacement control member. The control system includes a user input device and a command lever rotatably coupled to the displacement control member and capable of receiving the user input. The command lever provides a signal to the engine speed control device in response to the user input. The command lever also commands a given displacement via the displacement control member subject to load forces on the hydrostatic pump transmitted to a limiting mechanism coupled to the command lever and the displacement control member. |
