What It Is

This is a complete 46-inch mower deck rebuild kit designed to restore cutting performance on select Cub Cadet, Craftsman, and other MTD-built lawn tractors. It includes two spindle assemblies, two blades, one drive belt, and two idler pulleys—everything needed to replace worn or damaged deck components in one purchase.

Fitment & Compatibility

Before buying, confirm these three things:

• Deck size: This kit is for a 46-inch stamped deck only. Measure your deck width edge-to-edge. It will not fit 42-inch, 48-inch, or 54-inch decks.
• Model verification: Fits Cub Cadet LTX1045, LTX1046KW, Craftsman LT2000, and TB2246. Also compatible with many MTD, Troy-Bilt, and Yard Machines tractors using the same 46-inch deck. Check your owner’s manual or look up your model number.
• OEM vs aftermarket: The spindles (618-04636), blades (742-04244), belt (754-04219), and idlers (756-04129) are direct OEM replacement numbers. Measure your existing belt length (should be roughly 96–98 inches) and compare blade hole pattern (usually a 5-point star center) before installing.

Key Things to Know

• Installation difficulty: Moderate. Expect 1–2 hours if you’re mechanically handy. You’ll need a socket set, torque wrench, and possibly a puller for stubborn spindles.
• Quality: All components are aftermarket but meet OEM specs. The spindles include pre-installed bearings and grease fittings—grease them before first use for longer life.
• Common gotchas: Spindle bolts often seize. Soak them in penetrating oil overnight. Also, the blade bolt torque is critical—tighten to 70–90 ft-lbs to avoid blade throw.
• Belt routing: Take a photo of the old belt path before removing. The new belt may be slightly tighter; check your deck’s tensioner spring is in good shape.

Should You Buy It

This kit is a smart buy if your deck has vibration, uneven cut, or visible spindle wobble. It’s cost-effective compared to buying parts individually and includes everything for a full refresh. Best for DIY owners with a 46-inch Cub Cadet or Craftsman who want to avoid a shop visit. Skip it if your deck is rusted through or you only need a single blade replacement.
