ABSTRACT:
A change speed apparatus for a tractor comprising a combination of frictional stepless change speed means and planetary reduction means. A large diameter gear is used to drive the frictional stepless change speed means by means of engine output, and the frictional stepless change speed means includes a large diameter driven disc which engages an outer periphery of an internal gear of the planetary reduction means to be axially movable but not rotatable relative to the internal gear. The planetary reduction means is located in a space defined by the large diameter gear and the frictional stepless change speed means.
