2 Pack 11" Drive Wheels for Toro 137-4837 115-2885 119-0313 Fits for Toro Models: 20339 20378 20959 21329

What It Is

This is a 2-pack of 11-inch diameter rear drive wheels designed to replace worn or damaged wheels on Toro self-propelled walk-behind mowers. They’re intended for residential and light commercial use, providing traction and support for models that use these specific OEM-style wheels.

Fitment & Compatibility

Before buying, confirm your mower model matches one of the listed Toro models: 20339, 20378, 20959, 21329. These wheels also replace OEM part numbers 137-4837, 115-2885, and 119-0313. Measure your existing wheel’s diameter (11 inches), axle hole size (typically 5/8-inch), and tire tread width (about 2 inches). They are a direct OEM-style replacement—not universal—so they won’t fit other brands or Toro models outside the list. Check your mower’s deck size (usually 21-22 inches for these models) as a secondary cross-reference.

Key Things to Know

• Quality: Solid rubber tires on plastic hubs—durable for typical mowing, but not intended for heavy commercial use or rough terrain.
• Installation: Simple swap—remove the axle bolt or clip, pull off the old wheel, slide on the new one, and re-secure. No special tools needed.
• Common gotcha: The wheels fit only on the rear axle; front wheels are smaller and use different part numbers. Double-check you’re replacing rear wheels.
• Note: These are sold as a 2-pack, so you get both rear wheels—no need to buy separately.

Should You Buy It

If you own one of the listed Toro models and your rear wheels are cracked, worn smooth, or no longer gripping, this is a direct, cost-effective fix. It’s a simple DIY replacement that restores traction and stability. Not for universal mowers or non-Toro machines.
