PetMigo 46" Deck Spindle Rebuild Kit for MTD/Craftsman/Troy-Bilt — 23-1/4" Blade & 103-1/4" Belt, Fits 618-06989/918-06989

Complete 46-inch deck spindle rebuild kit by PetMigo that includes a replacement spindle, a 23-1/4" cutting blade, and a 103-1/4" drive belt engineered to fit many MTD, Cub Cadet, Craftsman and Troy-Bilt models.

When a mower deck starts vibrating, cutting unevenly, or the blade belt shows wear, replacing the spindle assembly, blade and belt together restores deck performance faster than piecing parts together. This PetMigo kit bundles the spindle (replacement for MTD 618-06989 / 918-06989), a heavy-duty 23-1/4" blade compatible with common Cub Cadet/MTD part numbers, and a 103-1/4", 1/2" wide belt that matches factory routing. The kit is sized for 46-inch decks and lists compatibility across numerous model families so you can repair the deck and get back to mowing with fewer trips to the parts counter.

Which machines will this rebuild kit work on?

The kit is intended for 46" lawn mower decks built by MTD, Cub Cadet, Troy-Bilt and related brands. It replaces common spindle and blade part numbers used across many models, and fits a range of tractors and zero-turns with a 46-inch cutting deck.

• Spindle replaces MTD numbers 618-06989 and 918-06989 (spindle height 6 7/8", pulley OD 6 1/4").
• Blade fits multiple Cub Cadet/MTD blades; dimensions: 23 1/4" length by 3 1/8" width.
• Belt length 103 1/4" with 1/2" width, compatible with listed 754-/954-04219 part numbers.
• Examples include MTD CLT46CVT, T1500/T1600/T1900 families, Troy-Bilt Bronco and Horse 46 models, Craftsman T-series and select Cub Cadet LTX models.

How does replacing the spindle, blade and belt together help?

Changing these three items at once eliminates common mismatch issues and reduces downtime. A fresh spindle ensures correct blade alignment, a new blade restores cutting quality, and a new belt reliably transfers power.

• Prevents premature belt wear caused by a worn spindle pulley.
• Restores even blade tip speed for a uniform cut.
• Simplifies maintenance — one install covers the most frequent deck failures.

What are the key specifications I should check before ordering?

Confirm deck diameter, spindle height and pulley dimensions plus blade length and belt route before purchase. Matching those numbers to your tractor’s service manual or existing parts prevents fitment issues.

• Spindle height: 6 7/8"; pulley outer diameter: 6 1/4".
• Blade size: 23 1/4" long × 3 1/8" wide with center hole pattern for listed models.
• Belt: 103 1/4" length, 1/2" width — for typical 46" deck routing.
• Cross-reference your machine’s parts list with the included replacement numbers.

What should I expect during installation and maintenance?

Installation typically requires standard hand tools and safe deck support. Remove the deck, replace the spindle, mount the blade and route the new belt following the deck diagram; torque spindle hardware to factory specs and check blade balance.

• Use jack stands or blocks to securely support the deck before working underneath.
• Inspect spindle bearings and housing surfaces; replace mounting bolts if damaged.
• After installation, test at low throttle then full speed to confirm quiet operation and level cut.

Who is this kit for: This PetMigo rebuild kit suits homeowners, landscapers and repair shops who maintain 46-inch decks on MTD-, Cub Cadet-, Troy-Bilt- or Craftsman-built tractors and zero-turn machines. It’s aimed at anyone wanting a single, compatible parts package to correct common deck issues — from worn spindle pulleys to dull blades and tired drive belts — without hunting multiple part numbers.
