Abstract

A multi ratio reversing powershiftable transmission having an input shaft, an output shaft, a plurality of countershafts, a drive wheel set, a distribution wheel set and a driven wheel set. The set of drive wheels includes a driven idler gear on each countershaft which can be optionally non-rotatably connected with the contershaft to cause a change of gear and direction of the transmission. The set of distribution wheels consist of at least one fixed gear on each countershaft for commutating rotation between communicating countershafts and the fixed gears of the set of driven wheels which in turn drive the output shaft.
