8TEN LawnRAZOR Mower Blade Set for MTD Cub Cadet LT1042 42 inch Decks 759-3830 742-3033 742-04101 759-04081 (Toothed)

What It Is

The 8TEN LawnRAZOR Mower Blade Set is a toothed (mulching) blade set designed for MTD and Cub Cadet LT1042 series lawn tractors with 42-inch cutting decks. It’s intended for mulching grass clippings into fine particles to return nutrients to the lawn.

Fitment & Compatibility

Before buying, check these three things:

• Deck size: Confirmed for 42-inch decks only. Measure your deck width if unsure.
• Model/brand fit: Fits Cub Cadet LT1042, LT1045, LT1050, LTX1040, and many MTD Huskee, Yard-Man, Troy-Bilt models using 42-inch decks. Cross-references OEM part numbers 759-3830, 742-3033, 742-04101, 759-04081.
• Measurements: Each blade is 20.5 inches long, 2.25 inches wide, with a 1-inch center hole and 7-point star drive. Confirm your blade’s length and center hole shape before ordering; star drive is less common than standard oval holes.

Key Things to Know

• Quality: 8TEN blades are heat-treated steel with a painted finish. They’re slightly thicker than OEM, which can improve durability but may require minor grinding to fit some decks.
• Installation: Moderate difficulty. You’ll need a socket wrench and blade removal tool (or wood block to lock blade). Torque bolts to 70–90 ft-lbs. The toothed edge is sharp—handle with gloves.
• Gotcha: The star drive pattern can be tricky if your spindle uses a standard oval hole. Verify your spindle’s drive shape before buying.
• Performance: Mulching quality is good, but they’re not designed for bagging or side-discharge. Expect finer clippings in dry grass; wet grass may clump.

Should You Buy It

If you own a Cub Cadet LT1042 or compatible MTD tractor with a 42-inch deck and want a budget-friendly mulching blade set that outperforms many OEM blades in durability, this is a solid choice. Skip it if you need bagging or side-discharge blades, or if your spindle uses a non-star drive.
