shiosheng 11-inch Drive Wheels for Toro 2-Pack — 11" Dia, 2-1/8" Tread, 1/2" Bore

Two 11-inch replacement drive wheels by shiosheng engineered to restore traction and smooth rear-wheel operation on compatible Toro mower models.

If your Toro lawn tractor is slipping, tracking poorly, or showing excessive rear-wheel wear, replacing the worn drive wheels can bring back dependable traction and alignment. This shiosheng two-wheel set fits several common Toro replacement part numbers and matches the original dimensions: 11-inch diameter, 2-1/8" tread width, 1/2" bore, and a 2-1/2" hub length. These wheels are supplied as a pair to replace both sides at once for even wear and consistent handling.

Which Toro machines will these shiosheng wheels fit?

These wheels are manufactured to be compatible with specific Toro models that use the listed OEM part numbers. Confirm fit by matching your mower’s model number and the original wheel measurements before ordering.

• Compatible models: Toro 20339, 20378, 20959, 21329
• Replaces OEM part numbers: Toro 137-4837, 115-2885, 119-0313
• Match dimensions: 11" diameter, 2-1/8" width, 1/2" bore, 2-1/2" hub length

How easy is it to install the replacement drive wheels?

Installation is straightforward for most home mechanics and usually requires only basic hand tools. The wheels bolt on to the axle hub and can be swapped in minutes once the mower is safely supported and secured.

• Tools needed: standard wrench or socket set
• No specialized press or bearings required for most installs
• Replace both wheels together for consistent tracking and wear

What are the exact dimensions and why they matter?

Keeping the same size and bore ensures proper engagement with the drive shaft and prevents misalignment or undue stress on the gearbox. Using wheels that match the original specs preserves handling and prolongs the drivetrain life.

• Diameter: 11" ensures correct ground clearance and gearing
• Width: 2-1/8" provides the intended contact patch for traction
• Bore: 1/2" and hub length: 2-1/2" secure proper fit on the axle

What performance improvements can I expect after replacing old wheels?

New drive wheels restore consistent traction, reduce side-to-side play, and can make steering feel firmer. Replacing both rear wheels at the same time helps the mower pull straight and reduces uneven wear on belts and gearbox components.

• Smoother acceleration and reduced wheel slip on slopes
• More predictable steering and tracking down rows
• Even wear pattern helps extend related drivetrain parts

Who is this for: This 2-pack of shiosheng 11" drive wheels is intended for homeowners and small-property maintenance technicians who own compatible Toro models and want an economical, OEM-dimension replacement. It suits anyone comfortable doing basic outdoor equipment repairs with a wrench, and for users who prefer replacing rear-drive wheels in matched pairs to maintain balanced handling and long-term component life.
