Abstract: A rotary lawn mower has one or more grass cutting blades that are rotatable in opposite directions about a vertical axis or axes. Each blade is double edged having front and rear cutting edges on each end of the blade. Each blade end has a front sloped face inboard of the front cutting edge and a rear sloped face inboard of the rear cutting edge. These faces create air flow within the cutting chamber when cutting grass regardless of the direction of rotation of the blade. The direction of rotation of each blade is reversed to switch between discharge and mulching modes of operation. A flow director has a curved vertical guide wall that guides the grass clippings through a discharge opening in the discharge mode and that guides the flow of grass clippings away from the discharge opening in the mulching mode.

Abstract: A walk power mower comprises a housing having an upwardly and rearwardly extending handle that is gripped by an operator. A load cell is responsive to the force applied by the operator to the handle during a grass mowing operation. Input from the load cell is used by a control system to vary the ground speed of the mower in accordance with the sensed operator applied force through control of an electric traction drive motor.

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 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: 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.
