TENGMUJX 50-inch mower deck rebuild kit — 3 spindles, 3 blades & belt, fits Cub Cadet/MTD/Troy-Bilt

TENGMUJX 50-inch mower deck rebuild kit delivers a ready-to-install set of three spindles, three blades and one drive belt designed to restore cutting performance on compatible Cub Cadet, MTD and Troy-Bilt models.

This comprehensive kit replaces worn deck components so your zero-turn or garden tractor can cut evenly and run reliably without searching for multiple parts. It bundles the most commonly replaced items for a 50-inch deck: three spindle assemblies that carry the blades, three sharp blades, and the primary deck belt. Each part corresponds to popular OEM numbers, making it straightforward to match your mower model and reduce downtime in one purchase.

Will these parts fit my mower model?

Compatibility covers many common 50" decks from Cub Cadet, MTD and select Troy-Bilt machines. The kit replaces OEM spindle numbers like 618-06980 and blade number 942-05052A, plus belt 954-04077A, so you can verify fit by comparing part numbers or deck specifications.

• Fits Cub Cadet XT1-GT50, XT2-ST54 and related models
• Compatible with MTD G8200/G8300 carriage models listed by OEM numbers
• Works with Troy-Bilt Mustang/Super Bronco 50 on matching decks
• Check your mower’s manual or existing part numbers before ordering

How does the kit restore deck performance?

Replacing worn spindles, dull blades and a stretched belt restores blade speed, deck stability and cutting quality. New spindles ensure proper blade alignment; fresh blades renew cutting edges; a new belt transfers engine power efficiently to the pulleys.

• New spindle assemblies reduce wobble and vibration for cleaner cuts
• Sharp blades minimize tearing and produce an even grass finish
• Replacement belt restores correct tension to prevent slipping
• Combined replacement reduces noise and wear on other deck components

What comes in the box and what OEM numbers do they replace?

The kit contains three complete spindle assemblies, three replacement blades and one deck drive belt. Each item is intended as a direct substitute for commonly used OEM parts, simplifying maintenance and helping you avoid sourcing individual components.

• 3 spindles replacing Cub Cadet/MTD 618-06980 / 918-06980
• 3 blades replacing MTD/Cub Cadet 942-05052A
• 1 belt replacing MTD/Cub Cadet 954-04077A
• All hardware packaged for straightforward deck installation

How easy is installation and what should I know before starting?

Installation requires basic mechanical skills and standard tools such as a jack or stands, socket set and torque wrench. Expect to remove the deck, unbolt old spindles and blades, and fit the new components following manufacturer torque specs for safe operation.

• Lift and secure mower before working under the deck
• Replace blades one at a time to maintain correct orientation
• Use recommended torque values for spindle nuts and hardware
• Inspect pulleys and deck shell for damage while parts are off

Who is this kit for? This rebuild kit suits homeowners, small property managers and repair shops who own or service 50-inch deck zero-turns and riding mowers from Cub Cadet, MTD or Troy-Bilt and want a single-package solution to restore cutting performance. It’s ideal when you’re replacing worn rotating parts together to save time and ensure matched components. If you prefer factory OEM components for dependable fit and reduced fiddling, this kit gives the essential replacements and a practical warranty-backed option to get your deck back to cutting condition.
