42 inch Deck Rebuild Kit - Fits MTD Craftsman Z6000 Zero Turn Mower, 2 Spindle (918-05137) 2 Blade (942-04308) 1 Belt (954-04033) 2 Idler (756-05042/756-04511B)

What It Is

This 42-inch deck rebuild kit includes all wear items (spindles, blades, belt, and idler pulleys) needed to restore cutting performance and reliability on MTD/Craftsman Z6000 zero-turn mowers with a 42-inch fabricated deck. It’s a one-stop refresh for decks that are cutting unevenly, vibrating, or shedding belts.

Fitment & Compatibility

• Deck size: Confirmed for 42-inch fabricated decks on Craftsman Z6000 (model series 917.28962, 917.28963, 917.28964) and similar MTD-built zero-turns with a 42-inch stamped/fabricated deck.
• OEM part numbers: Replaces spindles 918-05137, blades 942-04308, belt 954-04033, idlers 756-05042 and 756-04511B. Do not assume fit on other deck sizes (e.g., 46-inch, 48-inch) or non-Z6000 series.
• Check before buying: Measure your deck width (edge to edge). Verify your mower’s model plate number (under seat or on frame). Confirm your current spindle housing style – some older Z6000 decks use a different bolt pattern.
• Aftermarket note: This is a non-OEM kit. Spindles may not have grease fittings (OEM does). Blades are standard OEM-style but not hardened like original.

Key Things to Know

• Installation difficulty: Moderate. Requires removing the deck, disassembling spindles, and aligning the belt. Expect 2–3 hours if you have basic tools (socket set, jack stands, impact wrench).
• Common gotcha: Idler pulleys (756-05042/756-04511B) are often swapped left-to-right. Mark pulleys before removal – the tensioner arm orientation matters.
• Quality concern: User reviews note spindles may have slightly looser bearing tolerances than OEM. If you mow heavy grass or bumpy terrain, consider upgrading to OEM spindles separately.
• Belt length: The included belt (954-04033) is 93.5 inches. Verify your deck’s belt path – some Z6000 models use a different length if the deck has an additional idler.

Should You Buy It

Buy this kit if your Z6000 is cutting poorly, vibrating, or throwing belts, and you want an affordable, all-in-one refresh for a 42-inch deck. It’s best for DIY owners comfortable with basic mechanical work and who don’t need OEM-level durability for heavy commercial use. Skip it if you need greaseable spindles, run daily in rough terrain, or prefer factory-matched parts.
