ACEBRI 918-06991 Spindle Assembly 42 Inch for Craftsman T1200 T1000 T1400 T100 T110 T130 T1800 for Huskee LT4200 for Troy Bilt Pony Bronco TB42 Mower Deck Replaces for MTD 618-06991 2PCS

What It Is

This is a replacement spindle assembly for 42-inch cutting decks on select Craftsman, Troy-Bilt, and Huskee lawn tractors. It drives the mower blade via the deck belt and supports the blade pulley; sold as a pair (2 spindles) for complete deck servicing.

Fitment & Compatibility

• Deck size: 42-inch only—measure your deck width or check the model tag.
• Supported models: Craftsman T1000, T1200, T1400, T100, T110, T130, T1800; Troy-Bilt Pony, Bronco, TB42; Huskee LT4200. Also fits many MTD-built decks with 42-inch cutting width.
• OEM cross-reference: Replaces MTD 618-06991 and OEM part 918-06991. Verify your old spindle’s part number before ordering.
• Physical check: Measure the spindle shaft diameter (typically 5/8-inch) and overall height. Confirm the pulley mounting pattern matches your deck’s belt routing.
• Bolt pattern: Usually 3-bolt flange mount; ensure your deck uses the same spacing (approx. 3.5-inch center-to-center).

Key Things to Know

• Build quality: Aftermarket steel housing with sealed bearings—solid for homeowner use, but may not match OEM durability under heavy commercial loads.
• Installation: Straightforward bolt-on job with basic hand tools (socket set, wrench). You’ll need to remove the deck, belt, and old spindle; reinstall with new lock washers.
• Common gotcha: The included spindle does not come with a pulley or blade. Reuse your existing pulley and blade, or buy separately if worn.
• Pair sold together: Buying two saves time and ensures matched wear on both spindles, but confirm your deck uses exactly two spindles (some 42-inch decks use three).

Should You Buy It

If you own a 42-inch Craftsman, Troy-Bilt, or Huskee lawn tractor with a worn or noisy spindle, this is a cost-effective, well-reviewed replacement. It’s ideal for DIY homeowners who want a quick, bolt-on fix without OEM pricing. Not recommended for commercial mowers or decks requiring OEM-specific spindle geometry.
