Youxmoto RZT 42 Deck Rebuild Kit for 42" Cub Cadet & Troy-Bilt — 2 Spindles, 2 Blades, 96" Belt

The Youxmoto RZT 42 Deck Rebuild Kit is a complete replacement package that renews a 42" mower deck with two spindles, two blades, an idler pulley, and a 96" belt for compatible Cub Cadet and Troy-Bilt models.

This rebuild kit groups the most commonly worn deck parts into one purchase so you can restore cutting performance and reduce downtime. All components are manufactured to match fitment for many RZT-42, LTX1040/LTX1042 and model-equivalent riding mowers from Cub Cadet, Troy-Bilt and other compatible machines. The kit replaces multiple OEM part numbers for spindles, blades, pulleys and belts so you can be confident about compatibility with model years and serial ranges listed in the fitment details.

Which mower models and years will this kit work with?

The Youxmoto RZT 42 Deck Rebuild Kit is designed for a wide set of 42" decks including RZT-42, RZT-L42, RZT-S42 and multiple LTX1040/1042 variants spanning roughly 2010–2014 model years. The product replaces many common spindle and blade part numbers used across Cub Cadet and Troy-Bilt lineups, so it fits when your deck uses the listed OEM numbers.

• Compatible with Cub Cadet LTX1040, LTX1042 and RZT-42 series models.
• Fits Troy-Bilt Bronco, Super Bronco, Pony, Mustang 42 and related models.
• Replaces spindles 618-04822/918-04950 and blades 742-04126/942-04126 among others.

What exactly is included and how does each part help?

The kit assembles the core deck components: two spindle assemblies, two cutting blades, an idler pulley, and a 96" deck belt. Replacing worn spindles corrects wobble and blade misalignment, fresh blades restore a clean cut, and a new belt and pulley ensure consistent power transfer from the engine to the blades.

• Two spindle assemblies (match OEM replacement numbers listed for fitment).
• Two mower blades sized for 42" decks to restore cutting edge and balance.
• One idler pulley to maintain proper belt tension and routing.
• One 96" deck belt for reliable power delivery to spindles.

How difficult is installation and what tools are needed?

Installation requires basic mechanical skills and standard yard equipment tools. You will need wrenches, a socket set, a torque wrench for spindle mounting, and safety equipment; follow manufacturer torque specs and blade-balance checks for safe operation.

• Common tools: ratchet/sockets, wrenches, torque wrench, blade holder or block.
• Allow 1–2 hours per spindle for removal and installation if working carefully.
• Always disconnect spark plug and stabilize mower before starting service.

Will these parts match my OEM numbers and serial ranges?

The kit is engineered to replace numerous OEM part numbers listed in the fitment notes, including multiple spindle and blade references. Check your mower’s stamped part numbers or service manual against the list to confirm compatibility before ordering.

• Spindle replacements include 618-04822, 918-04822B and equivalents.
• Blades replace part numbers such as 742-04126 and 942-04126.
• Idler pulley and belt numbers correspond to common OEM replacements cited in fitment details.
