Abstract
A control system for a vehicle having a hydraulic drive device such as a hydrostatic transmission or integrated hydrostatic transaxle with a return to neutral feature and a brake mechanism. The system includes a pair of linkages connected to the vehicle brake pedal; one is engaged to the return to neutral arm and the other is engaged to the brake of the drive device, so that actuation of the vehicle brake pedal first causes the return to neutral feature of the drive device to engage to reduce vehicle speed and eventually to return the device to the neutral position. As the vehicle brake pedal is further actuated, the brake mechanism of the drive device is also engaged.
