KOOTANS Lawn Mower Spindle Replace for Toro Exmark Oz-line, Toro SS4235 SS5000 SS4200 and Timecutter 5060, Part Numbers 117-7267, 117-7439, Replacement Mower Deck 34" 42" 50" 60" Spindle Assembly

What It Is

This is a replacement spindle assembly for zero-turn and riding mower decks, specifically designed for Toro and Exmark models with 34", 42", 50", or 60" cutting decks. It drives the blade and houses the bearings that keep it spinning smoothly.

Fitment & Compatibility

Check these before buying:

• Deck size: Fits 34", 42", 50", and 60" Toro/Exmark decks, but verify your specific deck model (e.g., TimeCutter 5060, SS4235). Not all deck sizes within that range use the same spindle.
• OEM numbers: Replaces Toro 117-7267 and 117-7439. If your spindle has a different OEM number, measure mounting hole spacing and shaft diameter.
• Bolt pattern: Measure center-to-center distance of the three mounting bolts (typically 3.25" or 3.5" on these models). Also check shaft diameter (usually 1" or 1-1/8").
• Bearing housing height: Match the overall height of your old spindle to ensure blade clearance under the deck.

Key Things to Know

• Construction quality: This is an aftermarket (not OEM) part. Most users report it’s as good as OEM for the price, but a few note bearings may wear faster than Toro originals in heavy commercial use.
• Installation: Moderate difficulty—requires removing the deck, belt, blade, and old spindle bolts. A torque wrench is needed for blade bolts (typically 70–90 ft-lbs).
• Common gotcha: The spindle shaft may have a different keyway size than your blade adapter. Check your blade’s center hole diameter and keyway width before installing.
• Warranty: Usually 1-year limited. If you mow commercially or have a large property, consider OEM for longer life.

Should You Buy It

If you have a compatible Toro or Exmark residential zero-turn and want a reliable, budget-friendly spindle replacement, this is a solid choice. It’s less than half the price of OEM and works well for most homeowners. Skip it if you need commercial-grade durability or have a less common deck size—stick with OEM to avoid fitment headaches.
