46 inch Mower Mulching Blade Replacement for MTD Cub Cadet XT1-46 XT2 LT46 LTX1045 LTX1046, 46'' Deck Mower Replace for 942-04290 942-04290-X 942-04244 742-04244 742-04290 (2 Pack)

What It Is

This is a 2-pack of 46-inch mulching blades designed for MTD and Cub Cadet lawn tractors with a 46-inch deck. They replace OEM part numbers 942-04290, 942-04290-X, 942-04244, 742-04244, and 742-04290. Mulching blades have a curved, high-lift design to recut grass clippings into fine particles that decompose quickly, eliminating the need for bagging.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: Your mower must have a 46-inch cutting deck—measure from blade tip to blade tip across the deck if unsure.
• Model compatibility: Confirmed fit for Cub Cadet XT1-46, XT2, LT46, LTX1045, and LTX1046. Also fits MTD, Troy-Bilt, and other brands using the same OEM numbers. Check your owner’s manual or current blade part number against the list above.
• Measurements: Each blade is approximately 16.5 inches long, with a 1-inch center hole and a 7-point star center drive. Measure your existing blade’s length, hole diameter, and center pattern before ordering. These are not universal—do not assume they fit other 46-inch decks.

Key Things to Know

• Quality: Aftermarket blades at a budget price. Users report they are slightly thinner than OEM, but cut well and hold an edge for a season of normal use.
• Installation: Simple bolt-on replacement. Use a torque wrench to tighten to 40-50 ft-lbs. A common gotcha: the center hole and star pattern must align perfectly—if your spindle uses a different pattern, these won’t fit.
• Mulching vs. bagging: These blades are optimized for mulching. If you frequently bag or side-discharge, consider standard lift blades instead.
• Check deck clearance: After installing, manually spin the blade to ensure it doesn’t contact the deck. Bent or warped blades can hit the shell.

Should You Buy It

Buy these if you own a compatible 46-inch Cub Cadet or MTD tractor, need a cost-effective mulching blade set, and don’t mind an aftermarket alternative to OEM. They’re a solid value for the price, but if you need OEM thickness or run a high-hour commercial operation, stick with genuine Cub Cadet blades.
