Abstract: A walk power mower having a cutting deck supported upon the ground by a front and rear wheel(s). The mower includes a traction drive system incorporating a bidirectional transmission adapted to propel the mower alternatively in both forward and reverse directions. In some embodiments, the mower may include a single bidirectional transmission (e.g., powering only rear wheel(s) or only front wheel(s) of the mower), while in other embodiments, two bidirectional transmissions may be provided to power both the front and the rear wheel(s). In other embodiments, the mower may include a bidirectional transmission powering the rear wheel(s), while the front wheel(s) may be attached to the deck via a caster assembly.

Abstract: A walk power mower has a deck with an upwardly and rearwardly extending handle behind which a user walks when operating the mower. The mower is self-propelled by a variable speed traction drive. The handle includes a slidable handle grip for engaging and selecting a speed of the traction drive to control the ground speed of the mower. Forward ground speed is set by pushing the handle grip forwardly on the handle from a neutral position. Reverse ground speed if available is by pulling the handle grip rearwardly from its neutral position. The handle grip follows a curved path as it moves forwardly or rearwardly to flatten the path of travel of the handle grip from the travel that would have occurred absent the curved path.

Abstract: A walk power mower has a traction drive system that includes a front transmission powering a pair of front wheels and a rear transmission powering a pair of rear wheels. A first one of the transmissions provides forward motion of the mower when it is active and a second one of the transmissions provides rearward motion of the mower when it is active. A slidable handle grip on the handle having a cross bar long enough to be gripped by both hands of the user activates the first one of the transmission when it is slid downwardly on a handle out of a neutral position thereof. The slidable handle grip activates the second one of the transmissions when it is slid upwardly on the handle out of the neutral position.

Abstract: An assist handle for assisting an operator with climbing on to, or off of, a ground maintenance vehicle such as a mower, and a ground maintenance vehicle incorporating the same. The assist handle includes, in one embodiment, a grip portion movable between a deployed position, wherein the grip portion is positioned at a deployed elevation configured to assist the operator with ingress to, or egress from, a platform such as a seat; and a stowed position, wherein the grip portion is positioned at a stowed elevation lower than the deployed elevation.

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.

Abstract: A walk power mower has a deck that provides a cutting chamber for enclosing a rotary grass cutting blade. An assembly is provided for adding ambient air to the cutting chamber during a grass mowing operation to improve performance. The assembly comprises an air vent placed in a top wall of the cutting chamber. An external cover outside of the cutting chamber and above the top wall of the cutting chamber has an air permeable section located forwardly of the air vent to admit air into the cover to thereby feed that air to the air vent. An internal cover inside the cutting chamber and below the top wall of the cutting chamber receives the air passing inwardly through the air vent and discharges such air into the cutting chamber at a location that is spaced from the air vent.
