Abstract: A control system for controlling engagement of a first and second transmission of an all-wheel drive (AWD) walk-behind power equipment unit such as a lawn mower. The control system may include a mechanical load balancer to split an input drive force vector into two output force vectors. These two forces act upon associated first and second connection elements coupled to the first and second transmissions, respectively. One transmission may include a resistance element selected to sequence engagement of the first and second transmissions so that both transmissions begin driving their respective wheels at or near the same time even when the wheels associated with one transmission are more heavily-loaded than the wheels associated with the other transmission.

Abstract: A grounds maintenance apparatus such as a lawn mower adapted for movement from a horizontal operating orientation to a vertical storage orientation. Embodiments of the apparatus provide supplemental storage wheels adapted to permit rolling of the apparatus over a ground surface while in the vertical storage orientation.

Abstract: A grounds maintenance apparatus adapted for movement from a horizontal operating orientation to a vertical storage orientation. An operator handle of the apparatus may be moved from an operating position during operation, to a folded position for storage. A passive retainer may hold the handle in the folded position. Embodiments of such grounds maintenance apparatus further provide an auxiliary lift handle adapted for gripping by an operator when moving the apparatus between the horizontal operating orientation and the vertical storage orientation.
