This mount attaches to zero turn and stand-on mowers by setting the bar on the caster arms (35″-46.5″ arm spacing width) and strapping it with the provided 3/8” thick steel plates and hardware. A 10778 (9” drop) receiver needs to be purchased with this mount on almost all commercial mowers. Note: If your Z turn has a hitch receiver already, you can get the 2” hitch (10441) or 9” drop 2” hitch (10778) instead.
