Abstract: A cart pulling system for pulling a line of nested carts including a reelable retaining cord mechanism and a hitch to engage the line of nested carts. The reelable retaining cord mechanism is a dual spindle system which is attached to a motorized cart-puller. Attached to the spindles is a retaining cord which extends around and engages the line of nested carts. The retaining cord is preferably slidable with respect to the nested carts to prevent the line of nested carts from binding when they turn. A hitch is also attached to the motorized cart-puller and has a set of stationary jaws and set of movable jaws which slidably engage the line of nested carts.

Abstract: A powered grocery cart mover moves a line of grocery carts. The grocery cart mover includes a drive mechanism and a mechanism for engaging the line of grocery carts. The engaging mechanism is configured and arranged so that upon activation of the drive mechanism, the engaging mechanism lifts an end of the line of carts off the ground and moves the carts horizontally in a desired direction. The drive mechanism is pivotally connected to the cart engaging mechanism to facilitate steering of the cart engaging mechanism and the line of carts. The grocery cart mover can further include a harnessing mechanism releasably attachable to the cart engager and the line of carts for securing the line of carts relative to the cart engager.
