Durable construction

Durability comes from a robust build that combines a metal bearing, metal sleeve, and a rubber tread. This trio supports smooth gliding and long-lasting performance, even when mowing on uneven terrain across your yard.

  • Metal bearing for smooth rotation
  • Metal sleeve strengthens axle connection
  • Rubber tread delivers reliable traction

Precise sizing helps ensure a seamless replacement: 10.83 inches in diameter, 2-1/8 inches wide, 1/2 inch bore, and a hub length of 9.03 inches. These measurements align with common Toro axles for a near- factory feel.

Easy installation

Attaching the wheel is straightforward with a socket wrench. For best results, clean and grease the axle and bolt before you install, and tighten securely to reduce wobble during use.

  • Quick swap with a socket wrench
  • Grease the axle and bolt prior to install

Packaging options

Choose a convenient packaging format based on your needs: 1-pack for a single replacement or 2-pack for a ready spare. Either option keeps downtime to a minimum and your mower ready for ongoing yard work.

  • Available as 1-pack
  • Also available as 2-pack

Bottom line

This UPOW rear wheel is a practical, no-nonsense replacement that aligns with your mower’s geometry and working environment. While not a guarantee of performance, it offers a solid path to renewed mobility and dependable mowing sessions.
