Abstract
For tractors or like machines which can be provided, upon assembly, with either a hydrostatic transmission or a mechanical stepped-speed transmission, a transmission housing having a removable cover is provided. The machine has a drive shaft and a driven shaft and, according to the invention, a hydrostatic transmission is mounted intact upon the cover for introduction into and removal from the housing with this cover. The hydrostatic transmission comprises an inclined-disk variable-displacement pump whose input shaft is connected to the drive shaft and a hydraulic pump of the drive-flange type hydraulically connected to the pump and having an output shaft which is, in turn, connected to the driven shaft.
