John Deere TCA19309 Caster Wheel Assembly

This caster wheel assembly serves as a direct OEM replacement for John Deere part number TCA19309. The unit features a flat-free semi-pneumatic tire construction eliminating puncture downtime. The tire measures 13x6.50-6 with a rib tread pattern for traction on turf surfaces. The steel rim has a 6-inch diameter with a centered hub length of 5.726 inches and a 5/8-inch (0.625 inch) inner diameter bore equipped with heavy-duty ball bearings. The hub is powder-coated yellow for corrosion resistance. The assembly weighs approximately 7.39 kg (16.3 lbs). It is engineered for compatibility with John Deere ZTrak series zero-turn mowers and QuikTrak stand-on mowers powered by Kawasaki FX and Kohler Command Pro EFI vertical-shaft engines. Cross-reference interchange includes Rotary part number 16659, Stens AM-101589, and John Deere substitute AUC24723. The Carlisle Reliance tire brand is utilized for the flat-free tire component. Installation requires verification of axle bore size and hub length against the specific mower serial number break.
