What It Is

This 46" deck rebuild kit provides all the wear components needed to refresh the cutting deck on select Cub Cadet, MTD, Craftsman, and Troy-Bilt lawn tractors. It includes two spindle assemblies, two blades, two idler pulleys, and one drive belt—everything required for a complete deck overhaul in one package.

Fitment & Compatibility

Before buying, confirm these three things:

1. Deck size – Only fits 46-inch stamped steel decks, not fabricated or 42/50-inch decks.
2. Model series – Direct fit for Cub Cadet XT1-LT46, XT2-LX46; Craftsman T225, T240; Troy-Bilt Super Bronco 46, TB2246; and many MTD tractors with 46" decks (e.g., 13AL78, 13AL79, 13AL80). Check your mower’s model number plate under the seat or on the frame.
3. OEM part numbers – Kit uses OEM equivalents: spindles (918-06977), blades (742-04244), idlers (756-05034), belt (954-05022). If your mower uses different spindle or belt part numbers (e.g., 918-06977A or 954-05022A), this kit may not fit.

Measurement check: Deck belt should be 1/2" x 96.5". Measure your old belt length end-to-end before ordering.

Key Things to Know

• All-in-one convenience – Buying the kit saves 15–20% vs. purchasing each part separately, and ensures matched components.
• Installation difficulty – Moderate. Requires basic socket set, jack stands, and 1–2 hours. Spindle bolts are often torqued high (40–50 ft-lbs) and may need a breaker bar.
• Quality note – Aftermarket spindles and blades are generally reliable, but OEM parts may last longer in heavy-use or commercial mowing. Check that blade bolts and spindle bearings are greased before install.
• Common gotcha – The idler pulleys use a 5/8" bore; verify your existing idler arm bolt size matches. Some older decks use a 1/2" bore idler.

Should You Buy It

If your 46" Cub Cadet, Craftsman, or Troy-Bilt deck is vibrating, cutting unevenly, or shedding belts, this kit is a cost-effective way to restore performance. It’s ideal for DIY homeowners who want a single purchase to fix worn spindles, dull blades, and a stretched belt. Skip it if you need only one spindle or blade—buy individual parts instead.
