A powered lawn and yard implement for removing trash or like material from a lawn or yard and discharging the material into a wheeled pushcart. The implement includes a wheel supported housing to which the wheeled pushcart is releasably connected. A chute assembly directs trash from the housing into an upwardly open bin of the pushcart. The pushcart includes an elongated support roller and a pushbar assembly that facilitate independent movement of the pushcart assembly when detached from the housing. The housing includes a latching mechanism that may be operated from one side of the housing to secure or release the pushcart relative to the housing. Also associated with the latching mechanism is a deflector assembly that operates in response to operation of the latching assembly to open or close the discharge chute leading to the open bin. When the pushcart is detached from the housing, the deflector mechanism is located in position to prevent discharge of material through the chute. When the cart is attached to the housing, the latch mechanism and associated deflector mechanism are moved to positions wherein the latch mechanism releasably locks the pushcart to the housing and the deflector mechanism opens to become an integral part of the chute means, guiding discharged trash into the attached cart.

A powered machine for moving along the ground surface and producing a succession of holes therein to aerate the soil. The present aerator includes a pair of ground-penetrating members that are moved alternately to engage, penetrate, and disengage the ground's surface. They are moved both vertically and horizontally to "walk" the aerator in a forward path. Each ground-penetrating member is moved through an elliptical circuit in a vertical plane parallel with the forward path. The penetrating members are retained in substantially upright orientation throughout the complete circuit. They are tipped slightly as they engage and leave engagement with the ground to form a uniform upwardly open hole as the aerator is propelled forwardly.
