Abstract
A change speed apparatus for a tractor includes a main change speed device ( ) having a combination of gear trains mounted on a first shaft and a second shaft extending parallel to each other, for driving a change speed output shaft ( ) at a plurality of speeds, and a backward and forward drive switching device ( ) cooperable with the main change speed device ( ) to produces forward drive and backward drive in an equal number of speeds. Between the main change speed device ( ) and the backward and forward drive switching device ( ), the forward drive is transmitted through the first shaft ( ) and the backward drive is transmitted through the second shaft ( ). With this construction, a group of gears for returning reversed drive to a forward drive transmission shaft is omitted from the backward and forward drive switching device ( ). Consequently, the backward and forward drive switching device has a reduced fore and aft length, and thus the entire change speed apparatus also has a reduced fore and aft length.
