Convert a zero-turn to airless front and rear with one order. This complete set pairs two MICHELIN® X® TWEEL® Turf 24x12N12 rear assemblies with two 13" front casters in your choice of grooved or smooth tread, plus the 40653 spacers Michelin specifies for them, so every part for a full four-wheel swap comes in one order. Michelin's fitment guide matches this combination to 57 mower models from Bobcat, Country Clipper, Dixie Chopper, Exmark, Kubota and Toro.
The rear Tweels bolt to a 4x4" hub with a -0.75" offset and carry 750 lb each, while their poly-resin spokes flex to cushion the ride over bumps and uneven ground. Up front, the airless casters hold a consistent hub height for an even cut, and none of the four positions can go flat.
