What It Is

This is a set of two heavy-duty mulching blades designed for 46-inch cutting decks on Cub Cadet, MTD, Troy-Bilt, and Craftsman lawn tractors. They chop grass clippings finely for better nutrient recycling, reducing the need for bagging.

Fitment & Compatibility

Before buying, confirm your deck is exactly 46 inches (measured blade tip to tip). These blades are direct replacements for OEM part numbers 942-04290-X, 942-04290, 942-04290A, 942-04244A, 742-04244, and 742-04290. They fit most Cub Cadet, MTD, Troy-Bilt, and Craftsman models with a 46-inch stamped or fabricated deck, but always check your mower’s model number against the brand’s compatibility chart. Measure the blade length (20.5 inches) and center hole (1 inch) to verify. These are aftermarket, not OEM, so they meet or exceed OEM specs but may differ slightly in finish.

Key Things to Know

• Installation difficulty: Easy – requires a socket wrench and blade removal tool. Torque to 70-85 ft-lbs. Always disconnect the spark plug first.
• Quality: Heavy-duty steel with a Gator-style mulching wing design. Edge retention is good for residential use, but may dull faster on sandy or rocky lawns.
• Common gotcha: These blades are for mulching only – they won’t side-discharge or bag well. If you switch between modes, consider a universal blade set.
• Balance check: After installation, visually check blade balance on a nail or balancer. Uneven blades cause vibration and spindle wear.

Should You Buy It

If you own a 46-inch deck Cub Cadet, MTD, Troy-Bilt, or Craftsman tractor and want a reliable, affordable mulching upgrade for regular grass cutting, this 2-pack delivers solid performance. It’s a smart buy for homeowners who prefer fine mulching over bagging, but not ideal for rough terrain or heavy commercial use.
