What It Is

This 42" deck rebuild kit provides the main wear components to restore cutting performance on an MTD/Craftsman Z6000 zero-turn mower: two spindles, two blades, and two idler pulleys. It’s designed for a single service session to replace all high-friction parts on the deck at once.

Fitment & Compatibility

• Deck size: 42-inch cutting deck only. Measure deck width to confirm.
• Mower models: MTD and Craftsman Z6000 zero-turn mowers. Also fits many MTD-built 42" decks from brands like Yard Machines, Troy-Bilt, and Cub Cadet with the same spindle/pulley pattern.
• OEM cross-references: Spindles replace 918-05137 / 618-05137; blades replace 490-110-M108; idler pulleys replace 756-05042 / 756-04511B.
• What to check: Measure spindle bolt pattern (typically 3-bolt, 3.25" center-to-center) and pulley diameter (4" for idlers). Verify blade length is 18" with a 1" center hole and 0.5" offset. If your deck uses different spindles or a 5/8" blade hole, this kit won’t fit.

Key Things to Know

• Quality: Aftermarket parts; spindles are typically cast iron with sealed bearings—adequate for residential use but may not match OEM durability under heavy commercial use.
• Installation difficulty: Moderate. Requires basic tools (socket set, wrenches, possibly a puller for stuck spindles). Budget 1–2 hours if replacing all components.
• Common gotchas: Idler pulleys may need different belt routing—snap a photo before removal. Blades are pre-balanced, but check for wobble after install. Spindle bolts may be reverse-threaded on some decks; verify before tightening.
• No grease fittings: Spindles are sealed—replace entire unit when bearings fail, not serviceable.

Should You Buy It

Buy this kit if you own a Z6000 or compatible 42" MTD deck and want a single, cost-effective order to refresh worn spindles, blades, and pulleys. It’s ideal for homeowners who prefer a complete swap over piecemeal repairs. Skip it if you need OEM-grade spindles for heavy commercial use or if your deck uses non-standard spindle patterns.
