PetMigo 42" XT1 LT42 Deck Spindle Rebuild Kit — Fits MTD/Cub Cadet 618-06976, Includes Blade, Idler & 100" Belt

The PetMigo 42" XT1 LT42 deck spindle rebuild kit restores cutting performance by replacing worn spindles, blade, idler and belt with exact-fit components for many MTD, Cub Cadet and Craftsman models.

If your Cub Cadet or compatible lawn tractor is showing uneven cuts, vibration, or noisy deck operation, worn spindles, blades, idlers and belts are common causes. This complete kit addresses those wear points in one purchase: a spindle that replaces MTD/Cub Cadet 618-06976/918-06976, a sharp 21 1/4" blade, a 1/2" x 100" belt, and an idler compatible with John Deere and MTD part numbers. It’s built to fit specific XT1, XT2 and LX42 series models so you can repair the deck quickly and get back to consistent mowing without hunting for individual parts.

Which mower models will this kit work with?

This kit is made for 42" decks used on a range of Cub Cadet and MTD machines from recent model years. Confirm model and deck compatibility before ordering.

• Fits Cub Cadet XT1-LT42 variants including EFI, KH, and LT42 C series (model references like 13A8A1CS056 and 13AVA1CS009).
• Compatible with XT2-LX42 and XT2-LX42 EFI families (examples: 13AGA1CS010, 13WGA1CS010).
• Also suited to similar Craftsman and MTD machines that use spindles 618-06976 / 918-06976.

What exact parts are included and what do they replace?

The kit combines all deck wear items so you don’t need to track down multiple SKUs. Each replacement mirrors OEM shapes and mounting points for straightforward installation.

• Spindle: 6 1/2" height spindle replacing MTD/Cub Cadet numbers 618-06976, 618-06976A, 918-06976, 918-06976A.
• Blade: 21 1/4" cutting blade that substitutes for 742-04308 and related 742/942 series part numbers.
• Belt: 1/2" x 100" belt replacing 754-05021 or 954-05021 to restore deck drive tension.
• Idler pulley: OD 5-7/32" replacement compatible with MTD 756-05034A and John Deere GY20629/GY22082.

How will installing this kit change deck performance?

Replacing worn deck spindles and associated parts reduces vibration, improves blade speed consistency, and produces a more even grass cut. You’ll also lower the risk of further component damage by restoring proper belt tension and pulley alignment.

• Smoother operation with reduced wobble and noise from a new spindle assembly.
• Better cutting quality using a sharpened, correctly sized 21 1/4" blade.
• Reliable belt engagement and longer belt life after replacing the 1/2" x 100" drive belt.
• Proper idler alignment to prevent premature belt wear and skipping.

Before you begin installation, verify your tractor’s model and deck serial numbers, disconnect the spark plug, and follow safe lift and support practices for the deck. Basic mechanical tools are required: wrenches, sockets, torque wrench, and possibly a pulley puller depending on the existing setup. If you prefer, a professional small-engine shop can install the kit and torque parts to OEM specifications.

This PetMigo rebuild kit suits homeowners and repair shops who maintain Cub Cadet, MTD, or compatible Craftsman 42" decks. It’s ideal for owners wanting a single-order solution that replaces the most common deck wear parts with components matched to OEM references. If your machine is experiencing uneven cuts, deck vibration, burnt or glazed belts, or you see play in the spindle, this kit gives the essential hardware to return the deck to reliable mowing performance.
