8TEN Deck Blade Spindle Kit for Troy Bilt White Outdoor Bronco LTX1842 LT1742 LT1842 42-Inch 942-04308-X 918-0574C

What It Is

This is an aftermarket spindle assembly that holds and drives the blade on a lawn mower deck. It’s designed for Troy-Bilt, White Outdoor, and Bronco models with a 42-inch cutting deck, typically used on residential lawn tractors.

Fitment & Compatibility

Before buying, verify three things:

• Deck size – Must be 42-inch. Measure your deck or check the model number.
• Model compatibility – Fits Troy-Bilt Bronco LTX1842, LT1742, LT1842, and White Outdoor equivalents. Also replaces OEM parts 942-04308-X and 918-0574C.
• Physical dimensions – The spindle has a 1-inch diameter shaft and a 3-inch mounting flange bolt pattern (4 holes). Measure your old spindle’s bolt spacing and shaft length to confirm.
• OEM vs aftermarket – This is a non-OEM part. It should match the original, but minor differences in bearing quality or shaft finish can occur. If you have a different deck brand (e.g., MTD, Craftsman), cross-check the OEM part number first.

Key Things to Know

• Installation difficulty – Moderate. You’ll need a socket set, a jack to lift the mower, and possibly a puller if the old spindle is seized. Expect 30-60 minutes per spindle.
• Bearing quality – Some reviews note the bearings are adequate but not premium. They may wear faster than OEM under heavy use. Grease the spindle before install.
• Common gotcha – The bolt pattern can vary slightly between deck generations. Measure your old spindle’s bolt spacing (center-to-center) to avoid a mismatch.
• Included hardware – Kit usually comes with the spindle, bearings, and mounting bolts. Check that the bolts match your deck’s thread size (typically 5/16-18 or 1/4-20).

Should You Buy It

This is a good budget option if you need a direct replacement for a worn-out spindle on a 42-inch Troy-Bilt or White Outdoor tractor. It’s not the best choice for commercial use or if you want OEM-level longevity, but for occasional residential mowing, it gets the job done at a lower price.
