Abstract
A transmission is provided for selectively redirecting motive power for operating material handling equipment and, in particular, agricultural implements such as manure spreaders or the like. An operator may selectively redirect power from a single input to one or both of two driven outputs. The transmission is contained in a compact, substantially sealed housing or gearbox containing a power train for each of the two output shafts and includes at least a pair of clutches, the axis of rotation of the clutches being substantially coaxial about the input shaft. The output of one of the clutches is transferred through a two speed gear to a transfer output shaft that is spaced apart from and parallel to the input shaft. A single shift linkage or operating control is provided whereby the operator may selectively redirect the input power.
