Abstract

A compact transmission is provided which includes a leading two speed forward and one speed reverse countershaft transmission, and a trailing five speed planetary transmission to give ten forward and two reverse speeds particularly adaptable to an agricultural vehicle. Very desirable speed steps are achieved between gears in the greatest working range, and the transmission provides an elevated PTO function and auxiliary pump drives within the envelope.
