GICOOL 942-0610A Mower Mulching Blades (2 Pack) for 38" Deck MTD, Cub Cadet, Troy-Bilt, Bolens - Replaces 742-0610, 742-0610A, 942-0610 - Fits Huskee LT3800 & Murray

What It Is

This is a two-pack of mulching blades designed for 38-inch cutting decks on select MTD, Cub Cadet, Troy-Bilt, and Bolens lawn tractors. They replace OEM part numbers 742-0610, 742-0610A, and 942-0610, and are intended for mulching grass clippings into fine particles that decompose quickly.

Fitment & Compatibility

Before buying, confirm your deck is exactly 38 inches wide (measured blade tip to blade tip). These blades fit specific models including MTD 13A-326-190, Cub Cadet LTX1040, Troy-Bilt TB30R, and Huskee LT3800. They also fit Murray 38-inch decks using the same spindle pattern.

Key measurements to verify:

• Center hole: 7/8 inch diameter (round, no star or D-shape)
• Blade length: 19 inches overall
• Offset: 0.5 inch
• Thickness: 0.24 inch

This is an aftermarket replacement, not OEM. It matches the OEM profile but may have slightly different steel composition or coating. Check your current blade’s part number (stamped on the blade) — if it’s 742-0610, 742-0610A, or 942-0610, this set will fit.

Key Things to Know

• Installation note: These blades are not pre-balanced. You should balance them on a blade balancer before mounting to avoid vibration and spindle wear.
• Mulching vs. side-discharge: These are dedicated mulching blades with a curved, serrated design. They will not work well for bagging or side-discharge — you’ll get clumping.
• Torque matters: Tighten the center bolt to 70–90 ft-lbs. Under-tightening can cause the blade to slip and damage the spindle.
• Sharpness: They come sharp but dull faster on sandy or rocky soil. Expect to sharpen after 8–10 hours of mowing in normal conditions.

Should You Buy It

If you own a 38-inch MTD-family tractor (Cub Cadet, Troy-Bilt, Bolens, Huskee, or Murray) and primarily mulch your lawn, this is a solid, cost-effective replacement. The price is competitive with OEM, and the two-pack gives you a spare. Skip it if you need bagging or side-discharge blades, or if your deck uses a different center hole shape (star or D-hole).
