8TEN Blade Spindle Deck Kit for MTD Hechinger 42-Inch 942-0537 717-0906 917-0906A Lawn Tractors

What It Is

This is a complete blade spindle deck kit that replaces the factory spindle assembly on MTD and Hechinger 42-inch lawn tractors. It includes the spindle housing, bearings, pulley, and hardware needed to restore blade rotation on the cutting deck.

Fitment & Compatibility

Before buying, verify three things:

• Deck size: Fits 42-inch cutting decks only (not 46-inch or 38-inch).
• OEM part numbers: Replaces MTD 942-0537, 717-0906, and 917-0906A. Cross-check your tractor’s model number against these.
• Physical measurements: The spindle shaft diameter is 5/8-inch, and the pulley diameter is 4.5 inches. Measure your existing spindle to confirm these match.
• Brand compatibility: Designed for MTD, Hechinger, and many Craftsman or Yard-Man tractors using the same deck. Not universal—avoid if your deck uses a different bolt pattern or belt width.

Key Things to Know

• Installation difficulty: Moderate. Requires removing the deck, unbolting the old spindle, and transferring the blade. Basic hand tools (wrench set, socket) and a jack or blocks to lift the mower.
• Bearing quality: The 8TEN kit uses sealed bearings—less prone to debris damage than open bearings. Still, check for smooth spin before installing.
• Common gotcha: The pulley may have a different offset than OEM. Test belt alignment after mounting; you might need a washer shim to center the belt.
• No blade included: This is the spindle assembly only. You’ll need a separate 42-inch blade set if replacing blades too.

Should You Buy It

Buy this if your MTD/Hechinger 42-inch deck has a worn or seized spindle (vibration, uneven cut, or blade won’t spin). It’s a solid aftermarket replacement at a fair price—just confirm your model number matches before ordering. Skip it if you have a different deck size, or if you just need a blade (buy a blade kit separately).
