42 Inch Deck Rebuild Kit Replace for MTD/Cub Cadet/Troy Bilt CC30 Mini Rider LTX1040 LTX1042 RZT-42, with 2 Spindles 918-04822 918-04950, 2 Blades 742-04308, 2 Idlers 756-04129, 1 Belt 754-04060

What It Is

This 42-inch deck rebuild kit provides all the wear components needed to refresh the cutting deck on select MTD, Cub Cadet, and Troy-Bilt lawn tractors—specifically the CC30 Mini Rider, LTX1040, LTX1042, and RZT-42 models. It’s designed for a complete one-and-done overhaul: new spindles, blades, idlers, and belt.

Fitment & Compatibility

Before buying, confirm three things:

• Deck size must be exactly 42 inches – this kit will not work on 46-inch or 54-inch decks.
• Check your model numbers – fits Cub Cadet CC30, LTX1040, LTX1042, RZT-42, and Troy-Bilt/MTD equivalents with 42-inch fabricated or stamped decks. Verify your tractor’s model number on the frame tag.
• OEM cross-reference – spindles replace 918-04822 and 918-04950; blades replace 742-04308; idlers replace 756-04129; belt replaces 754-04060. If your deck uses different spindle or blade part numbers, this kit won’t fit.

Key Things to Know

• Installation is intermediate – replacing spindles requires removing the deck, accessing spindle housings, and torquing bolts properly. Plan 2–3 hours if you have basic mechanical skills.
• Blades are standard 42-inch replacements – 742-04308 blades are 18-1/2 inches long with a 1-inch center hole. They’re not high-lift or mulching; fine for standard cutting.
• Inspect existing pulleys and bearings – the kit includes idlers, but worn spindle bearings are the main failure point. If your old spindles are seized or wobbling, this kit solves it.
• Belt is a single, continuous V-belt – route it exactly as shown in your deck diagram. Wrong routing causes slippage or deck damage.

Should You Buy It

If your 42-inch MTD/Cub Cadet/Troy-Bilt deck has noisy spindles, dull blades, or a slipping belt, this kit is a cost-effective, complete refresh. It’s right for DIY owners who want to avoid buying parts individually and don’t want OEM markup. Skip it if you only need blades or a belt alone—those are cheaper separately.
