PROPEL MACHINERY

The propel machinery consists of two motors, a gear package, a power transfer assembly, and a walking eccentric, arm and shoe. There is a similar setup on each side of the machine. To move, the walking dragline physically lifts the back of the base frame (tub) and machinery house off the ground, and drags the entire machine backwards.
