Abstract
A controllable mechanical brake release system for controllably releasing a mechanical brake included in a hydrostatic machine is disclosed. In the preferred embodiment the hydrostatic machine is located on an incline. The mechanical brake is included in a mechanical braking system. The hydrostatic machine has the braking system, a hydrostatic propulsion system and a controller. A determined hydraulic pressure associated with the hydrostatic propulsion system is compared with an established trip indicator. A release mechanical brake signal is produced in response to the comparison.
