Pack of 2 Spindle Assembly for Toro 110-6866 117-1192 42 inch Deck Mower TimeCutter Z4200 Z4202 Z4220 Z4235

What It Is

This is a pack of two replacement spindle assemblies for select Toro 42-inch deck TimeCutter zero-turn mowers. The spindles house the bearings and shaft that spin the mower blades; if your deck vibrates excessively, makes grinding noises, or won’t cut evenly, these are likely the culprit.

Fitment & Compatibility

What to check before buying:

• Deck size: Fits Toro 42-inch fabricated decks only—not 44”, 50”, or 54” decks.
• Model compatibility: Confirmed for TimeCutter Z4200, Z4202, Z4220, and Z4235 models. Also fits some older 42” Toro zero-turn and lawn tractors, but verify your deck’s spindle hole pattern.
• OEM cross-reference: Replaces Toro OEM parts 110-6866 and 117-1192. If your original spindle has a different part number, measure the bolt pattern (usually 3 bolts on a 3-inch center) and shaft diameter (0.625” or 0.75”).
• What to measure: Center-to-center distance between mounting bolts, shaft length, and pulley bore size. This pack uses a 3-bolt pattern with a 5/8” shaft; confirm yours matches.
• Includes: Two complete spindle assemblies with bearings, housing, and shaft. You’ll need to reuse your existing pulleys, blade adapters, and bolts.

Key Things to Know

• Quality: Aftermarket spindles at this price point are adequate for residential use but may have shorter bearing life than OEM Toro spindles. Expect 1-3 seasons under normal mowing.
• Installation difficulty: Moderate. Requires removing the deck, swapping the spindle, and torquing bolts to spec (typically 35-45 ft-lbs). Have a socket set, breaker bar, and penetrating oil for rusted bolts.
• Common gotcha: The spindle shaft may be slightly shorter or longer than OEM—check that your blade adapter and pulley sit flush. If the shaft is too short, the blade won’t engage properly.
• Bearing preload: Some aftermarket spindles come with loose bearings; spin the shaft by hand before installing. If it feels gritty or rough, return them.

Should You Buy It

If you have a Toro 42” TimeCutter with a wobbling or noisy spindle and want a quick, budget-friendly fix for a residential lawn, this two-pack is a solid value. But if you mow commercially or need maximum durability, spend more on genuine Toro spindles—these are a temporary patch, not a permanent upgrade.
