Abstract: An outdoor power equipment unit, such as a lawn mower, includes a frame movable over the ground. A handle assembly is provided on the frame to allow an operator to walk on the ground behind the handle assembly while operating the unit. A traction drive and a ground grooming or working implement are carried on the frame. A traction control hand grip and an implement control bail are carried on the handle assembly. Both the hand grip and the bail are movable relative to the handle assembly by flexure provided by first and send compliant mechanisms.

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 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: 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.
