Abstract
An outdoor power equipment unit includes a front wheel independent suspension system. The front wheel independent suspension system includes a frame, a first front wheel assembly, a second front wheel assembly, a first laterally-extending suspension arm pair, and a second laterally-extending suspension arm pair. The first laterally-extending suspension arm pair includes a first suspension arm and a second suspension arm, both coupled to the frame and the first front wheel assembly. The second laterally-extending suspension arm pair includes a third suspension arm and a fourth suspension arm, both coupled to the frame and the second front wheel assembly. Both the first suspension arm pair and the second suspension arm pair are configured to independently pivot about the frame such that each of the first front wheel assembly and the second front wheel assembly are vertically displaceable relative to the frame.
