ABSTRACT:
A transaxle especially for use with small tractors, power equipment and the like wherein a range transmission is incorporated within a speed transmission to provide a unique drive that provides three forward and one reverse normal speed drives and two or three forward creep speed drives of extreme reduction ratio. Also shown, in variation, is a planetary epicyclic gear train that replaces the reverting gear trains currently employed in these transaxles to provide for more compact and economical construction. In one variation a friction drive clutch is contained within the transaxle receiving an input from a primary reduction gear and providing an input to the speed transmission mainshaft.
