Abstract

A shift assisted brake control system for a power machine or vehicle is disclosed. In illustrated embodiments, the shift assisted brake control system employs a shift assisted brake sequence. In illustrated embodiments, the shift assisted brake sequence shifts an operating speed of a hydrostatic transmission or motor from a high speed to a low speed upon activation of a brake switch or device. This reduces impact or wear to the brake mechanism. In illustrated embodiments, the transmission or motor remains at the low speed for a pause period and following the pause period, the transmission or motor is shifted to the high speed.
