Replacement 942-0610A Mower Blades Compatible with MTD LT-400 Riding Mowers, Mulching Blades Fit for Troy-Bilt Tuffy 38" Deck Tractors, Replace for 742-0610, 742-0610A, 942-0610, 2 Pack

What It Is

This is a two-pack of mulching blades (part 942-0610A) designed for MTD LT-400 riding mowers and Troy-Bilt Tuffy tractors with a 38-inch cutting deck. They cut grass into fine clippings for nutrient recycling, ideal for mulching without bagging.

Fitment & Compatibility

Before buying, check these three things:

• Deck size: Only fits 38-inch decks. Measure your deck width (blade tip to tip) to confirm.
• Model/brand: Directly compatible with MTD LT-400 series and Troy-Bilt Tuffy models. Also fits many Craftsman, Cub Cadet, and Yard Machines tractors with 38-inch decks using OEM part numbers 742-0610, 742-0610A, or 942-0610.
• Measurements: Blade length is 18.5 inches, center hole is 1 inch diameter, with a 5-point star center. Verify your existing blade matches these dimensions.

Key Things to Know

• Installation: Simple—remove blade bolt, swap blades, torque to 70-90 ft-lbs. No special tools beyond a socket wrench and blade removal tool.
• Mulching vs. standard: These are mulching blades (curved, with extra cutting edges), not high-lift blades. Use them with a mulching plug or cover; they won’t throw clippings far for bagging.
• Common gotcha: Ensure blade orientation—the curved edge should face upward toward the deck. Reversing them will cause poor cutting and vibration.
• Quality: A solid aftermarket option at half the price of OEM, but may not hold an edge as long. Check for balance before installing.

Should You Buy It

If you own an MTD LT-400 or Troy-Bilt Tuffy with a 38-inch deck and want a reliable, budget-friendly mulching blade replacement, this 2-pack delivers. It’s a straightforward swap for DIYers, though you’ll get slightly less durability than OEM. Skip it if you need high-lift blades for bagging or have a non-38-inch deck.
