CUB CADET 634Z07284-0637 Caster Wheel Assembly Powder Black 13X6.50-6

What It Is

This is a genuine OEM Cub Cadet caster wheel assembly (part #634Z07284-0637) designed for zero-turn mowers and select lawn tractors. It replaces a worn or damaged front caster wheel, providing a 13x6.50-6 tire on a powder-coated black rim with integrated bearings and axle hardware.

Fitment & Compatibility

Before buying, confirm your machine uses a 13x6.50-6 tire size (6" rim diameter, 13" overall height, 6.50" width). This assembly fits many Cub Cadet zero-turn models including the Z-Force, ZTX, and Z-series, as well as some RZT and commercial units. Check your model number against Cub Cadet’s OEM parts diagram—this is a direct replacement, not a universal wheel. Measure the bolt pattern (typically a single 1/2" or 5/8" axle bolt) and verify the caster fork width (usually 3-4 inches). It will not fit older Cub Cadet tractors with smaller 11x4.00-5 or 15x6.00-6 tires.

Key Things to Know

• Genuine OEM part – Powder-coated black finish resists rust better than painted alternatives. Expect longer life than aftermarket wheels on rough terrain.
• Pre-assembled – Comes with bearings and axle hardware installed. No pressing or extra parts needed—bolt-on replacement in 15-30 minutes.
• Tire pressure – Run 15-20 psi for most zero-turn mowers. Underinflating can cause premature sidewall wear or rim damage.
• Check caster fork condition – If the fork is bent or the bushings are worn, replacing just the wheel won’t fix wobble. Inspect the fork pivot before buying.

Should You Buy It

Buy this if you need a direct OEM replacement for a Cub Cadet zero-turn mower with a 13x6.50-6 tire. It’s the right choice for owners who want a bolt-on fit with no modifications and prefer factory durability over cheaper universal wheels. Skip it if your machine uses a different tire size or if the caster fork itself is damaged—you’ll need to replace that separately.
