Abstract
A compact countershaft transmission includes three shafts, a plurality of gears, and low, high and reverse clutch assemblies to provide either one or two forward speeds and one reverse speed. The low and high clutch assemblies are arranged along the second shaft and the reverse clutch assembly is located along the third shaft. The countershaft transmission provides a moderate drop height between the first and third shafts, and is coupled to a trailing planetary transmission that provides a plurality of speeds for each range of the countershaft transmission. The countershaft transmission is compatible with a PTO section and provides positive drive to a plurality of pumps.
