8TEN Mower Spindle for Toro 50 inch Deck Timecutter Z4200 Z4202 Z4220 Z4235 Z5020 110-6866 117-1192 3 Pack

What It Is

This is a 3-pack of replacement spindle assemblies for the 50-inch cutting deck on Toro Timecutter zero-turn mowers. The spindles house the bearings that spin the blades; if your deck vibrates, cuts unevenly, or makes grinding noises, these are likely the culprit.

Fitment & Compatibility

• Exact Fit: Toro Timecutter Z4200, Z4202, Z4220, Z4235, Z5020 (all with 50-inch deck). Also fits Z Master Commercial 5000/6000 series with 50-inch deck.
• OEM Cross-Reference: Replaces Toro 110-6866 and 117-1192. Measure your existing spindle housing height (center of mounting flange to bottom of shaft) – should be 4.25 inches.
• What to Verify: Confirm your deck is truly 50 inches (measured blade tip to blade tip). Measure the spindle bolt pattern: 3 bolts on a 3.25-inch circle. If your deck uses a different bolt spacing or shaft length, this won’t work.
• Deck ID: Check the underside of your deck for a stamped model number (e.g., 50-xxxx) or look up your mower’s serial number on Toro’s site.

Key Things to Know

• Quality: These are aftermarket units with double-sealed bearings. Most users report they match OEM durability for a fraction of the price, but expect slightly tighter tolerances than Toro factory parts.
• Installation Difficulty: Moderate. You’ll need a socket set, a torque wrench (specs: 35-40 ft-lbs for spindle bolts), and a puller to remove the old spindle from the blade adapter. Plan 1-2 hours for all three.
• Common Gotcha: The included bolts may be metric (M10x1.5) while your deck uses SAE – check your old bolts before tossing them. Also, the blade adapter (the square hub) is not included; reuse yours unless damaged.
• Tip: Replace all three spindles at once even if only one is bad – the others are likely close to failure. While you’re in there, replace blades and check belt tension.

Should You Buy It

If you own a Toro Timecutter with a 50-inch deck and need to stop vibration or uneven cutting on a budget, this 3-pack saves you money over buying singles. It’s a solid value for DIY owners comfortable with basic wrenching. Skip it if you have a different deck size or want OEM-only parts for a commercial fleet.
