Will this kit fit my tractor or zero-turn mower?

How will this kit affect cutting quality and deck balance?

Replacing both the spindle and blade renews the core rotating assembly, which restores straight, even cuts and reduces vibration. A balanced blade and properly seated spindle help maintain deck stability and extend the life of belts and bearings.

• Precision-cut blade reduces scalping and feathering for cleaner stripes.
• Spindle designed to meet OEM tolerances for correct pulley and blade alignment.
• Lower vibration protects deck components and improves operator comfort.
• Correct center hole pattern ensures secure mounting and even rotation.

What are the key dimensions and replacement part numbers I should verify?

Before purchase, confirm your mower’s existing part numbers and compare spindle and blade measurements to guarantee compatibility. The kit replaces common OEM numbers used by Cub Cadet and MTD for 46" applications.

• Spindle replacement for Cub Cadet/MTD: 918-06977, 918-06977A.
• Blade replacements include numbers: 742-04244, 742-04244A, 742-04290, 942-04244 variants.
• Blade length: 23 2/9"; width: 3"; center: 6-point star hole.
• Spindle height: 6 1/2"; pulley outer diameter: 6 1/4" for belt fitment checks.

How difficult is installation and what tools are recommended?

Installation is moderate: someone comfortable with basic mechanical tasks can replace the spindle and blade with common tools, but a second person or lift makes alignment easier. Follow safety steps like disconnecting the spark plug and supporting the deck before starting.

• Recommended tools: socket set, torque wrench, pry bar, blade removal tool, jack or deck hoist.
• Typical steps: remove deck, unbolt old spindle, press out bearings if needed, install new spindle, mount blade and re-torque bolts.
• Expect 1–2 hours for an experienced DIYer; allow more time for bearing servicing or unexpected rust.

Who is this for: This PetMigo 46" deck rebuild kit is aimed at owners and service technicians of Cub Cadet and MTD 46-inch mower decks who need a direct-fit spindle and blade replacement that restores OEM-style performance. It's well suited for homeowners maintaining a single machine, lawn care pros keeping a fleet running, and shops that prefer a complete rebuild part set instead of sourcing components separately.
