Probably wouldn't be a good idea to tow any significant distance with the rear wheel on the ground due to wear and tear on the belt and right-angle drive. I'm considering an A-frame tow arm if I can figure out how to mount tow-points to the front of the Slingshot to attach to the A-frame towbar, but to tow any distance the belt should probably be removed.
Polaris insists a trailer should be used for towing.
