Bularie 8" Front Wheel Drive Assembly (2-Pack) for Troy-Bilt/MTD Mowers — S-wave Tread & Cogged Hub

The Bularie 634-05039 is a direct-fit 8" front wheel drive assembly replacement engineered to restore traction and smooth wheel engagement on compatible Troy-Bilt, MTD, Craftsman and Cub Cadet self-propelled mowers (sold as a 2-pack).

When a mower's front wheel becomes worn, cracked, or loses its cog engagement, steering and self-propelled drive performance suffer. This replacement set is designed to match common OEM part numbers and restore the intended front-wheel drive function without expensive dealer service. The assemblies feature an aggressive S-wave tread and cogged inner design to help re-establish traction and positive mesh with drive components.

How do I know this wheel fits my mower?

Verify compatibility by checking the OEM numbers and the mower model list. The Bularie 634-05039 corresponds to several original part numbers and fits many Troy-Bilt/MTD/Craftsman/Cub Cadet models; matching your mower’s part number ensures correct fitment.

• Replacement part numbers: 634-05039, 634-06986, 703386, 634-0244, 734-04475.
• Compatible with many Troy-Bilt models including TB200, TB210, TB220, TB230, TB270ES, TB280ES and listed model codes.
• Check your mower manual or the stamped OEM number on the old wheel for confirmation.

What makes the S-wave tread and cogged hub useful?

The S-wave tread pattern provides multidirectional contact with grass, soil and light debris for improved grip, while the cogged inner hub helps the wheel engage with the drive mechanism reliably. Together they help reduce slip and improve the responsiveness of self-propelled systems.

• S-wave tread improves traction on uneven or damp turf.
• Cogged hub aligns with drive gears for positive engagement.
• Durable molded rubber resists cracking under typical lawn use.

How difficult is installation and what tools do I need?

Installation is straightforward and designed for a homeowner with basic tools. You remove the existing wheel nut, swap the wheel assembly, and retighten the nut; a socket set is recommended and gloves protect your hands while working.

• Typical install time: a few minutes per wheel for most users.
• Tools: appropriate socket or wrench; optional penetrating oil if nut is corroded.
• Hardware and rear wheels are not included; this listing is for the front wheel assemblies only.

What are the package contents and key specifications?

The product ships as a two-pack of front wheel drive assemblies sized approximately 8" diameter by 2" width. These are sold as replacement front wheels only and do not include mounting bolts, nuts, or rear wheel components.

• Package: 2 x wheel drive assemblies (8" x 2").
• Intended use: front drive wheel replacement for compatible self-propelled mowers and some chore equipment.
