TENGMUJX 50-Inch Mower Deck Rebuild Kit for MTD/Cub Cadet — 3 Spindles & 3 Blades

This TENGMUJX kit bundles the core wear parts you need to restore cutting performance on 50-inch decks: three spindle assemblies, three high-strength blades, and the mounting hardware to get the deck back in service. The components are made to match common OEM part numbers so they fit a wide range of models from Cub Cadet, MTD, Troy-Bilt and other makes produced in similar chassis and deck layouts.

Which machines will this rebuild kit work with?

The kit targets 50-inch decks used on many Cub Cadet, MTD and Troy-Bilt zero-turn and lawn tractor models from approximate model years shown by OEM references. It replaces common spindle and blade part numbers to simplify identification and ordering.

• Compatible with Cub Cadet models including i1050, LT1050, RZT50 series, SLT/SLTX and LGT series (various years).
• Fits MTD/Columbia and White Outdoor ZT-50 variants produced in listed years.
• Also suitable for Troy-Bilt Mustang XP and Craftsman ZTL7000 where spindle and blade specs match.

What parts are included and how do they match OEM numbers?

The package contains the essential components to replace worn spindles and blades across a three-pulley deck configuration. Each replacement item corresponds to widely used OEM references so you can confirm fitment before installation.

• Three mower spindles that replace OEM 618-04126, 618-04126A and similar 918/618 series references.
• Three blades compatible with 490-110-C123, 742-04053 and related blade part families.
• Hardware kit: three top nuts, three protective plastic caps, and twelve mounting bolts for secure installation.

How does installing this kit improve deck performance?

Replacing worn spindles and blades restores blade-to-deck geometry, reduces vibration and produces a more even cut pattern. Fresh bearings and balanced blades reduce load on the engine and prolong the life of belts and pulleys.

• New spindles bring correct blade height and alignment back to factory tolerances.
• Sharpened, balanced blades improve grass discharge and clipping size for tidy stripes.
• Complete hardware set avoids missing fasteners and speeds up the rebuild process.

What should I know about installation and durability?

Installation requires basic mechanic tools and moderate mechanical skill; torque specs and safety procedures should follow your mower’s service manual. The parts are manufactured under quality control processes to deliver reliable operation when installed correctly.

• Follow your mower manual for deck removal, blade removal torque and spindle bearing break-in guidance.
• Inspect pulleys, belts and deck shell while rebuilding; replace any worn items to maximize kit longevity.
• TENGMUJX provides customer support if you have fitment or installation questions.

Who is this for: This kit is aimed at homeowners, landscapers and small-property maintenance pros who need a cost-effective way to refresh a 50-inch mower deck when spindles and blades are worn. If you own a compatible Cub Cadet, MTD, Craftsman or Troy-Bilt model and want to restore cutting quality without buying a new deck, this TENGMUJX rebuild kit supplies the matched parts and hardware to complete the job efficiently.
