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.

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.
