Abstract
An outdoor power equipment unit having a frame including at least one laterally-extending structural member and at least a pair of opposite, longitudinally-extending side structural members, a first front wheel assembly, and a second front wheel assembly. The unit also includes a first pair of substantially parallel, laterally-extending suspension arms pivotally coupled to the first front wheel assembly to form a first 4-bar linkage arrangement, and a second pair of substantially parallel, laterally-extending suspension arms pivotally coupled to the second front wheel assembly to form a second 4-bar linkage arrangement. The unit further includes at least one longitudinally-extending first side suspension arm coupled to the first front wheel assembly and to a first one of the longitudinally-extending side structural members, and at least one longitudinally-extending second side suspension arm coupled to the second front wheel assembly and to a second one of the longitudinally-extending side structural members.
