42 inch Deck Spindle Assembly 110-6866 117-1192 Fits for Toro Timecutter Z4200 Z4202 Z4220 Z4235 Z5020, for Toro 74330-74399 and 74820

What It Is

This 42-inch deck spindle assembly (OEM numbers 110-6866 and 117-1192) is the rotating hub that drives the mower blade on Toro Timecutter zero-turn mowers. It replaces a worn or failed spindle to restore cutting performance.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: This assembly is for 42-inch decks only. Check your mower’s deck measurement (cutting width).
• Model numbers: Confirmed fit for Toro Timecutter Z4200, Z4202, Z4220, Z4235, Z5020, plus Toro models in the 74330-74399 and 74820 range. If your model isn’t listed, compare your OEM part number (stamped on the old spindle) to 110-6866 or 117-1192.
• Physical check: Measure the spindle shaft diameter (likely 1 inch), bolt pattern, and overall height. This is a non-OEM replacement—dimensions match original, but verify pulley and blade mounting holes align.

Key Things to Know

• Quality: Aftermarket part with solid reviews (4.4/5). Most users report it’s comparable to OEM, but a few note slightly looser tolerances on bearings—grease it well before install.
• Installation difficulty: Moderate. You’ll need a socket set, torque wrench, and possibly a puller to remove the old spindle. Expect 30-60 minutes per spindle.
• Common gotchas: The pulley nut may be reverse-threaded on some Toro models—check your service manual. Also, this is a single assembly; if you have a 3-spindle deck, buy three for even wear.
• Warranty: Not specified—likely none, so inspect for damage on arrival.

Should You Buy It

If you own a compatible Toro Timecutter with a 42-inch deck and need a cost-effective replacement (about 40% less than OEM), this is a solid pick. It’s best for DIYers comfortable with basic mower repair who want to avoid dealer markup. Skip it if you prefer OEM parts for warranty or exact fit.
