What It Is

This is a replacement spindle assembly for 38-inch cutting decks on select Toro, MTD, and Cub Cadet lawn tractors. It houses the bearings and pulley that drive a single mower blade, and it’s intended for residential or light commercial use.

Fitment & Compatibility

Before you buy, confirm these three things:

• Deck size: This spindle fits 38-inch decks only. It will not work on 42-inch or larger decks.
• Model cross-reference: Verified fit for Toro LX425, LX426, LT3812, LT542H, LT3800; MTD CTL38G, M135-38; and Cub Cadet LT3800. Also replaces OEM numbers 918-04474, 618-04474, 918-04474A/B, 618-04474A, 618-04495, and Toro 112-6083.
• Measure your spindle: The overall height is approximately 4.5 inches, the mounting bolt pattern is 2.75 inches center-to-center, and the shaft diameter is 5/8 inch. Verify these match your old spindle before ordering. This is an aftermarket part, not genuine Toro/MTD.

Key Things to Know

• Quality: 4.2 stars from 4 reviews is a thin sample. Some users report the bearings are adequate for residential use but may wear faster than OEM under heavy or frequent mowing.
• Installation difficulty: Moderate. You’ll need a socket set, a jack to lift the deck, and possibly a puller to remove the old spindle. Expect 30–60 minutes per spindle.
• Common gotcha: The pulley may not be pre-installed; you’ll need to reuse your old pulley or buy a separate one. Also, the mounting bolts are not included—reuse your originals or buy grade 8 hardware.
• No grease fitting: This spindle is sealed and non-serviceable. When the bearings fail, you replace the whole assembly.

Should You Buy It

If you need a budget-friendly replacement for a 38-inch deck on a Toro, MTD, or Cub Cadet tractor and are comfortable with moderate DIY work, this spindle is a reasonable choice. It’s not built for heavy commercial use, but for a residential lawn with standard conditions, it should get the job done. If you prefer guaranteed longevity or have a larger deck, stick with OEM.
