8TEN Mower Spindle for Toro 42 50 inch Deck Timecutter Z4200 Z4202 Z4220 Z4235 Z5020 110-6866 117-1192

What It Is

This is a replacement spindle assembly for Toro Timecutter zero-turn mowers with 42-inch or 50-inch fabricated decks. It mounts the mower blade and houses the bearings that allow the blade to spin freely.

Fitment & Compatibility

• Fits Toro Timecutter models: Z4200, Z4202, Z4220, Z4235, Z5020.
• Deck sizes: 42-inch and 50-inch fabricated decks only (not stamped steel).
• Replaces OEM part numbers: 110-6866 and 117-1192.
• Physical check: Measure spindle shaft diameter (must be 1-inch) and overall height (approx. 5.75 inches). Verify bolt pattern matches your deck’s mounting holes (three bolts on ~3-inch center).
• Not compatible with Toro Z4000/Z5000 series zero-turns that use different spindle designs.

Key Things to Know

• Build quality: Aftermarket unit with sealed bearings. Many users report it matches OEM Toro performance at half the cost.
• Installation difficulty: Moderate. Requires removing the deck, belt, blade, and pulley. A puller may be needed if the old spindle is seized.
• Common gotcha: The included bolts may be slightly different thread pitch than original—test fit before tightening. Use thread locker.
• Bearing life: Expect 1-2 seasons of residential use. Commercial operations should stick with OEM for longer lifespan.

Should You Buy It

If you own a Toro Timecutter with a 42 or 50-inch fabricated deck and need a budget-friendly spindle replacement for residential mowing, this is a solid choice. For commercial use or if you prefer zero risk on fitment, buy the OEM part.
