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 has a deck with an upwardly and rearwardly extending handle behind which a use 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.
