Abstract: It is connected to a lawn tractor or vehicle for towing any foldable sheet type material such as a tarp, (construction) plastic, or cloth across the ground to move large debris or material. This assembly contains multiple tubing, stabilizers, and hardware that allow a direct connection to a lawn tractor or a vehicle/ATV using a standard receiver type hitch. The sheet material is folded and then rolled onto the tarp connection tube and then attached to the tarp support tube. When towing, the clamping point gets tighter the harder you pull on it, making it a strong connection. Now the material is tightly gripped between these two tubes, which allow the use of any type of foldable sheet material for towing. This design eliminates the need to use any type of grommet load connection points within the sheet material that could be easily pulled out during heavy loads or use.
