Grasscool 942-0610A Mulching Blades for Bolens Cub Cadet Troy Bilt Huskee LT3800 MTD Murray 38 inch Deck Lawn Mower Replace for 742-0610 742-0610A 942-0610 (2 Pack)

What It Is

This is a two-pack of mulching blades designed to replace OEM part numbers 742-0610, 742-0610A, and 942-0610 on 38-inch cutting decks. They’re made for mulching grass clippings into fine particles that decompose quickly, reducing bagging needs.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 38 inches wide—measure center to center of the blade mounting holes. These blades fit most MTD-built tractors with 38-inch decks, including Bolens, Cub Cadet (LTX1040, LTX1042, RZT50), Troy-Bilt (Pony, Bronco), Huskee (LT3800), and Murray. They also work with Craftsman and Yard Machines models using the same spindle pattern. Check your old blade’s part number—if it ends in 0610, 0610A, or 0610B, these are direct replacements. The center hole is 7/8-inch round, and the blade length is 18.25 inches. Aftermarket, not OEM, so expect slight finish differences but identical dimensions.

Key Things to Know

• Installation tip: Torque blade bolts to 70–90 ft-lbs. Use a blade removal tool to hold the spindle—don’t let it spin free.
• Mulching vs. side-discharge: These blades have a higher lift and more curved surface than standard blades. They work best with a mulching plug or cover installed. If you switch to bagging, performance drops.
• Sharpness out of box: Blades come with a dull edge for safety. You’ll need to sharpen them before first use—use a bench grinder or file, keeping the original angle.
• Balance check: Always balance blades after sharpening. An unbalanced blade vibrates, wears spindle bearings, and leaves uncut grass.

Should You Buy It

If you own a 38-inch MTD-based tractor and want to mulch without bagging, this is a solid, affordable option. It’s not for heavy-duty commercial use, but for residential lawns up to 2 acres, it delivers clean cuts and fine clippings. Avoid if you primarily side-discharge or bag—standard blades work better for those tasks.
