YiaChuii Replacement Spindle Assembly 2-Pack for 30" & 42" Mower Decks — Triple-Sealed Bearings, Pulley Included

If your lawn tractor or zero-turn mower is producing uneven cuts, vibrating, or the blades wobble, worn spindle assemblies are often the cause. This YiaChuii two-pack includes fully assembled spindles with pulleys, mounting screws, and blade nuts designed to match multiple MTD, Cub Cadet, Troy-Bilt and Craftsman OEM part numbers. Before ordering, verify the model and dimensions — overall height 6-7/8" (173 mm) and pulley outer diameter 6-1/5" (158 mm) — to ensure correct fit.

How will replacing the spindle assembly impact my mower’s cutting quality?

Swapping a damaged spindle restores blade stability and keeps the cutting deck level, improving cut consistency across the lawn. The triple-sealed bearings in these spindles are built to reduce play and resist debris, delivering smoother rotation during mowing.

• Restores blade alignment for even cutting
• Reduces vibration that causes uneven swaths
• Triple-sealed bearings lower contamination risk
• Includes pulley and hardware for direct replacement
