ABSTRACT:
An assembly for receiving input power and delivering that power to a range pack transmission in either a forward or a reverse mode. One or more first gears are drivingly connected to the source of input power. One or more second planet gears are also drivingly connected to the source of input power. The first and second planet gears are meshingly interconnected. The first planet gears meshingly engage a ring gear that may be selectively grounded to effect reverse rotation of the sun gear with respect to the carrier. The second planet gear meshingly engages the sun gear which serves as an output to deliver power from the reversing assembly to a range pack transmission.
