Abstract
Outdoor equipment, such as a lawn mower, includes a frame, a riding area, front wheels, and a wheel assembly. One wheel assembly includes an outer plate, a rotating bracket pivotally connected to the outer plate, a primary wheel supported by the rotating bracket, and a secondary wheel supported by the rotating bracket. The rotating bracket is rotatable about a pivot axis, the primary wheel is axially offset from the pivot axis, and the secondary wheel is axially offset from the primary wheel and from the pivot axis. In use, the rotating bracket consistently provides two points of contact (one by the primary wheel and another through the secondary wheel) by rotating automatically about the pivot axis due to gravity and forces transferred through the wheels. This enhanced distribution of forces may provide a more comfortable, cushioned riding experience.
