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

What It Is

This is a 2-pack of mulching blades designed for 38-inch cutting decks on select MTD and Troy-Bilt riding mowers. They are intended for mowers that mulch clippings back into the lawn rather than side-discharging or bagging.

Fitment & Compatibility

• Deck size: 38-inch cutting deck only. Verify your deck’s stamped model number (e.g., 38A, 38C) matches.
• Mower models: Fits MTD LT-400 series and Troy-Bilt Tuffy tractors with a 38” deck. Also compatible with other MTD-built brands (Cub Cadet, Yard Machines, Huskee) that use a 38” stamped deck.
• OEM cross-references: Replaces 742-0610A, 742-0610, 742-0610A, and 942-0610. These are aftermarket blades, not OEM Troy-Bilt.
• Measurements: Blade length is 18.5 inches, center hole diameter is 7/8 inch, and the blade is 0.25 inches thick. Measure your old blade to confirm these dimensions.
• What to check: Look at your current blade’s part number (stamped on the blade). Confirm deck width is exactly 38 inches—some 36” or 42” decks look similar but won’t fit.

Key Things to Know

• Mulching vs. standard: These are designed for mulching—they have a curved, high-lift shape and a closed wing to chop clippings finely. They will not discharge or bag well. If you switch between mulching and bagging, you’ll need separate blades.
• Installation: Simple bolt-on job. Use a torque wrench (40-50 ft-lbs). The blade must be oriented with the cutting edge facing the direction of rotation (usually stamped on the blade). Re-torque after the first mowing.
• Common gotchas: The blades are sharp out of the box—handle with gloves. Check the blade adapter/drive pulley for wear before installing. If the center hole is wallowed out, replace the adapter.
• Quality: Aftermarket steel, not heat-treated like OEM. Expect slightly shorter life (2-3 seasons vs. 3-4 for OEM). Balance is generally good out of the pack, but it’s wise to check with a blade balancer.

Should You Buy It

Buy these if you own a 38” MTD/Troy-Bilt riding mower, want to mulch clippings, and don’t mind aftermarket blades. They’re a solid budget choice for homeowners, but if you need OEM durability or plan to switch between mulching and bagging, spend more on genuine Troy-Bilt or Oregon blades.
