Abstract
An improved hydrostatic transmission for use in a transaxle comprising a means for mechanically diverting hydraulic fluid from the hydraulic transmission to a sump to enable the vehicle to be moved with minimal resistance from the hydraulic fluid by unseating at least one of the hydraulic displacement units from its running surface to allow the fluid to drain quickly from the transmission to the sump, and an improved check valve mechanism on the center section of the transmission.
