Abstract
A hauling device for leaves, litter, and other materials such as stone, earth, mulch, manure and tree stumps comprises a tarpaulin with flexible support members and a rope including a unique assembly whereby the operator may secure and haul the collected material by pulling a loop of the rope. The tarpaulin is fitted with flexible support members within hems along the rear side edge and along a portion of each side edge. The rope ends are attached to the tarpaulin at both sides and threaded through the apertures of hardware located at both front and rear corners, thus providing a loop along the front side to be grasped either by the operator or a mechanical device such as a tractor. Once material is collected on the surface of the tarpaulin, the operator pulls the loop and thereby harnesses the rear and side edges, flexes the support members, and in unison confines the collected material. As the operator continues to pull the loop, obstructions on the rope arrest the confining action to provide a towline for the operator to haul the device along the ground to another location. To unload the material, the operator releases the loop and grasps the device along the rear side and rolls…
