Abstract
A tractor change speed apparatus includes a manual change speed device having a combination of gear trains mounted on first and second parallel shafts and driving a change speed output shaft at various speeds. A backward and forward drive switching device is cooperable with the main change speed device for producing forward and backward drives in an equal number of speeds, wherein the forward drive is transmitted through the first shaft and the backward drive is transmitted through the second shaft. A group of gears for returning reverse drive to a forward drive transmission shaft is thereby omitted. Consequently, the backward and forward drive switching device and the entire change speed apparatus has a reduced longitudinal length.
