634-0190A Front Drive Wheels Replacement for MTD 734-04581, 634-0190(A), Compatible with MTD, Yard Man, Craftsman, Huskee, Yard Machines Self Propelled Walk-Behind Mowers, 2 Pack

What It Is

This is a 2-pack of front drive wheels (part 634-0190A) for self-propelled walk-behind mowers from MTD, Yard Man, Craftsman, Huskee, and Yard Machines. They replace worn or broken front wheels that drive the mower forward.

Fitment & Compatibility

• OEM reference: Replaces MTD 734-04581 and 634-0190(A). Check your mower’s model number against these part numbers.
• Measurements: Wheel diameter is 8 inches; axle hole diameter is 5/8 inch. Measure your old wheel before buying.
• Fitment: Fits most MTD-branded self-propelled mowers (Craftsman, Yard Man, Huskee, Yard Machines) with front-wheel drive systems. Does not fit rear-wheel drive or zero-turn mowers.
• What to check: Verify your mower uses a 5/8-inch axle and that the wheel hub matches the drive pin configuration. Some models have a keyway or D-shaped hole—this wheel uses a round hole with a drive pin.

Key Things to Know

• Quality: Solid aftermarket replacement. Users report good durability for the price, but the plastic hub may wear faster than OEM on heavy-duty use.
• Installation: Simple—remove the old wheel’s cotter pin or retaining clip, slide off, and slide on the new one. No special tools needed.
• Gotcha: The drive pin slot on the wheel must align with your mower’s pin. If your mower uses a keyed shaft, this wheel won’t fit.
• Pack: Includes two wheels, but no hardware (axle pins, clips). Reuse your old hardware or buy separately.

Should You Buy It

If your MTD, Craftsman, or Yard Machines self-propelled mower has a worn or broken front drive wheel and your axle is 5/8 inch with a drive pin, this is a reliable, affordable fix. It’s not for heavy commercial use, but for typical residential mowing, it’s a solid choice.
