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. Please see the mount guide below to make sure this bar will fit on your mower. Note: If your Z turn has a hitch receiver already, you can get the 2” hitch (10441) or 9” drop 2” hitch (10778) instead.
