What It Is

This is a 3-pack of spindle assemblies (including pulleys) designed for Toro TimeCutter zero-turn mowers. Each spindle is the rotating hub that drives the mower blade—critical for cutting performance and deck balance.

Fitment & Compatibility

Check before buying:

• Deck size: Fits 42-inch decks (SS4200, SS4225, SS4260) and 50-inch decks (MX4200, MX5000, MX5050). Verify your deck width and model number (e.g., “TimeCutter SS4225”).
• OEM cross-reference: Replaces Toro OEM #117-7268, 117-7439, 121-0751, 117-0751, 117-7267. The included pulley (125-5575) is the correct one for these spindles—no separate pulley needed.
• Measurements: Each spindle has a 1-inch diameter shaft and uses a 5/8-inch hex spindle nut (standard for Toro). If your deck uses a different nut size or shaft diameter, this won’t fit.
• Brand note: This is an aftermarket part—not genuine Toro. Quality is generally good, but check reviews for any batch defects (e.g., loose bearings or misaligned pulleys).

Key Things to Know

• Installation difficulty: Moderate—requires removing the deck, unbolting the old spindle (3 bolts per spindle), and swapping the pulley (single bolt). A socket set and torque wrench are recommended.
• Common gotcha: The pulley bolt is reverse-threaded on some Toro spindles—check your old spindle before forcing it. Also, ensure the spindle housing is fully seated in the deck hole to avoid wobble.
• Quality: Aftermarket spindles often use sealed bearings (good for longevity), but some users report slightly shorter lifespan than OEM. The 3-pack saves ~30% vs. buying singles.
• Deck balance: Replace all three spindles at once to maintain even blade height and vibration-free cutting—mixing old and new can cause uneven wear.

Should You Buy It

This is a solid value for DIYers who need to replace all three spindles on a 42- or 50-inch Toro TimeCutter. If you’re on a budget and comfortable with basic mower repair, the 3-pack beats buying singles. Avoid if you need exact OEM fitment or have a different deck size (e.g., 46-inch or 54-inch).
