634-05039 Wheel Drive Assembly, Fits Troy-Bilt MTD Craftsman Cub Cad et Lawn Mower - 8" Front Wheel Assembly, Compatible with TB200 TB210 TB220 TB230 TB270ES TB280ES Mower (2 Pack)

What It Is

This is a two-pack of 8-inch front wheel drive assemblies designed for Troy-Bilt, MTD, Craftsman, and Cub Cadet walk-behind lawn mowers. It replaces the OEM part 634-05039 and is intended for mowers with a front-wheel-drive system, common on models like the TB200, TB210, TB220, TB230, TB270ES, and TB280ES.

Fitment & Compatibility

Before buying, confirm your mower has an 8-inch front wheel and a drive system that uses a square axle (typically 7/16-inch). Check your model number against the list: TB200, TB210, TB220, TB230, TB270ES, TB280ES (and similar TB-series). Also verify your mower brand—Troy-Bilt, MTD, Craftsman, or Cub Cadet—and that the deck size is 21–22 inches (these are standard on those models). If your mower uses a different axle shape (e.g., hex or keyed), this won’t fit. Measure the wheel hub diameter and axle hole to be sure.

Key Things to Know

• Quality: This is a direct OEM replacement, not an aftermarket knockoff. It includes the wheel, tire, and drive gear—no separate hub or bearing to buy.
• Installation: Moderate difficulty. You’ll need to remove the old wheel, slide this on, and secure it with the existing clip or pin. No special tools required, but check for rust or debris on the axle.
• Common Gotcha: The drive gear inside the wheel can wear out over time, causing slipping. If your mower struggles to move forward, this assembly is likely the fix. Also, ensure the axle is clean and not bent—bent axles won’t work with this assembly.
• Durability: The rubber tire is solid and holds up well on grass and light gravel, but avoid heavy use on concrete or asphalt to prevent premature wear.

Should You Buy It

If you own a compatible TB-series Troy-Bilt, MTD, Craftsman, or Cub Cadet mower and your front wheel is worn, slipping, or damaged, this is a cost-effective, direct-fit replacement. It’s well-rated and comes as a pair, so you can replace both front wheels for even traction. Avoid it if your mower uses a different axle type or wheel size.
