42 Inch Mower Deck Spindle Assembly Fit for Troy Bilt Pony TB42 Craftsman T100 T110 T130 T1000 T1200 T1400 T1800 Huskee LT4200 Lawn Mower Replaces OEM 918-06991 618-06991 2 Pack

What It Is

This is a 42-inch mower deck spindle assembly (2-pack) that drives the cutting blades on your mower deck. It’s designed for Troy-Bilt Pony TB42, Craftsman T-series, and Huskee LT4200 lawn tractors, replacing worn or damaged spindles to restore blade rotation and cutting performance.

Fitment & Compatibility

Before buying, confirm your mower has a 42-inch deck and matches one of these models: Troy-Bilt Pony TB42, Craftsman T100, T110, T130, T1000, T1200, T1400, T1800, or Huskee LT4200. This set replaces OEM numbers 918-06991 and 618-06991. Measure your existing spindle: shaft diameter is typically 5/8-inch, with a 3-inch pulley and 1-inch bearing height. Check that your deck uses a square or hex spindle shaft (this one is square). If your deck has a different shaft shape or pulley size, it won’t fit. Also verify you need two spindles—some decks use three.

Key Things to Know

• Quality: Aftermarket part with solid reviews (5.0/5 from 4 ratings), but it’s not OEM. Expect comparable durability for residential use.
• Installation difficulty: Moderate. You’ll need basic tools (wrenches, socket set) and may need to remove the deck and belt. Watch for a retaining clip or bolt on the pulley.
• Common gotcha: The spindle may come without grease fittings—check the product description or photos. If not, you’ll need to add grease manually. Also, ensure the bearing housing is sealed to prevent debris ingress.
• Pack size: Two spindles per pack. If your deck has a third spindle (common on 42-inch decks), you’ll need a separate single unit or another pack.

Should You Buy It

If you need to replace two spindles on a compatible 42-inch Troy-Bilt, Craftsman, or Huskee lawn tractor and want a budget-friendly option with solid early reviews, this is a good pick. It’s not OEM but should handle typical residential mowing. Avoid if you need a third spindle or have a different deck size.
