Means of adjusting ground speed of a vehicle based on load on blade assembly

A system for operating a hydromechanical transmission having a movable input member that transmits a signal to a control unit that uses predefined logic to determine if a hydrostatic transmission should be in a first low speed mode that uses displacement control or if it should be in a second high speed mode that uses a power, torque, or speed control scheme.
