11 Inch Drive Wheels for Toro 137-4837, 115-2885, 119-0313 Lawn Mower Rear Wheel Tire Fits for Toro 20339 20378 20959 21329, 1 Pack

What It Is

This is a genuine OEM 11-inch rear drive wheel for select Toro walk-behind lawn mowers. It replaces worn or damaged tires that provide traction and propulsion, specifically designed for residential and commercial Toro models with 11-inch rear wheel requirements.

Fitment & Compatibility

Before buying, verify your mower’s model number (stamped under the seat or on the frame). This wheel fits Toro models 20339, 20378, 20959, and 21329 among others. It replaces OEM part numbers 137-4837, 115-2885, and 119-0313. The wheel diameter is exactly 11 inches; measure your existing rear wheel to confirm. This is a rear wheel only—do not use on front positions. It fits standard 5/8-inch axle diameters common on Toro. Check that your mower uses a single-bolt wheel retention system (not a pin or clip). Not compatible with non-Toro brands or universal wheels.

Key Things to Know

• Quality: OEM Toro part, not aftermarket. Expect durable rubber and proper tread pattern for consistent traction on grass and light slopes.
• Installation: Moderate difficulty. Requires removing the old wheel’s center bolt, sliding off the old wheel, and reversing. No special tools beyond a socket wrench (usually 7/16” or 1/2” bolt). Torque to ~20 ft-lbs.
• Common Gotcha: The wheel may be tight on the axle due to corrosion. Use penetrating oil (e.g., WD-40) and a mallet to gently tap it off. Do not force—risk damaging axle or wheel hub.
• Single Pack: This is a 1-pack, so buy two if replacing both rear wheels. Check if your mower uses the same wheel on both sides (most do).

Should You Buy It

If you own a compatible Toro mower with a worn, cracked, or bald rear wheel, this is a direct, hassle-free replacement. It’s a genuine OEM part at a fair price, with high user satisfaction. Avoid if you need a front wheel, a different brand, or a budget aftermarket option—stick with this for guaranteed fit and longevity.
