    Abstract: A utility cart for lawn and garden applications and adapted for mounting on a lawnmower for catching vegetation clippings from the lawnmower. The cart includes at least one wheel that is in a stowed position when the cart is mounted on a lawnmower such that the at least one wheel bears no weight of the cart. The cart has substantially rigid walls and a handle movable between stowed and deployed positions. The handle pivots with respect to the cart by way of pins in a pivot slot and a guide slot.
