ABSTRACT:
A transaxle or gear drive unit with an improved shift mechanism and gear drive is set forth. The shift mechanism is of the shift key type and certain gears have recesses to receive a lug of the shift key with the recesses having ramps which depress the lug when the key is shifted. One of the gears has a smooth bore adjacent the recesses to serve as a neutral position for the shift key. A wide gear having teeth or splines around its periphery extending the length thereof is rotatably mounted on one shaft of the gear drive unit. The wide gear has a plurality of additional gears affixed thereto for simultaneous rotation. The wide gear extends beyond the additional gears and connects with a forward speed gear and a reverse gear on another shaft. The wide gear thus functions as a mechanical connection for the additional gears as well as serving as a gear itself.
