A 1:1 right angle gearbox is available for the DIFF 1, 7 and 20 HP units. The right angle box may be mounted to either or both sides of the Differential, including single or through-shaft configurations. The shaft rotation of the right angle gearbox may be specified in either direction.

The single-shaft right angle gearbox may be mounted to the Differential in any of four positions. The through-shaft option is available for mounting in two positions, vertical or horizontal. The preferred side for mounting is the left side of the Differential.
