What It Is

This is a 3-pack of spindle assemblies for 42-inch and 50-inch mower decks, designed to replace worn bearings and housings that cause blade wobble, vibration, or uneven cutting. It fits select Exmark and Toro TimeCutter zero-turn mowers.

Fitment & Compatibility

Before buying, confirm your deck size is 42" or 50". This 3-pack fits Toro TimeCutter models: 4200, 4216, 4235, 4260, 5000, 5060, SS5000, SS4225, SS4200, SS4235, and compatible Exmark decks. These are aftermarket replacements for OEM part numbers 117-7268, 117-7267, 117-0751, 117-7439, 121-0751, 139-3214, and 285-923. Measure your spindle bolt pattern (typically 3-bolt, 3.5-inch center-to-center) and shaft diameter (commonly 5/8" or 7/8"). Check your deck’s spindle spacing—some 50" decks use three spindles, others two. Verify blade mounting hole size matches your blades.

Key Things to Know

• Quality: Aftermarket spindles at this price point are generally reliable, but may have slightly shorter bearing life than OEM. Inspect for smooth rotation and proper grease seals before installation.
• Installation: Moderate difficulty—requires removing the deck, flipping it, unbolting old spindles, and transferring pulleys. A torque wrench is recommended (tighten pulley bolts to 40-50 ft-lbs). Expect 1-2 hours for all three.
• Gotchas: Pulleys often have a keyway or locking collar—don’t lose those parts. Some decks need a spindle puller if seized. Check blade spindle shaft for wear or bending before installing new ones.
• Deck variation: Not all 42" or 50" decks are identical—measure your existing spindle height and bolt pattern to avoid mismatch.

Should You Buy It

If you have a Toro TimeCutter or compatible Exmark with a 42" or 50" deck and need to replace all three spindles at once, this 3-pack saves money over buying singles. It’s a solid budget-friendly alternative to OEM, especially for DIY maintenance. If you need exact OEM fitment or have a different deck size, look elsewhere.
