ILONPA 942-04308-X 942-04308 42" Mulching Blades for Troy-Bilt Pony Super Bronco Mustang Cub Cadet XT1 XT2 42 ZT1 RZT-42 LT42 LTX1040 Craftsman T110 T1200 42 inch Lawn Tractor Zero-Turn Mower, Black

What It Is

This is a set of three 42-inch mulching blades, designed to replace OEM part 942-04308 on select Troy-Bilt, Cub Cadet, Craftsman, and MTD-brand lawn tractors and zero-turn mowers. They are intended for cutting grass and finely chopping clippings to return nutrients to the lawn.

Fitment & Compatibility

Before buying, measure your existing blade length—these are exactly 42 inches total (tip to tip) and use a 5-point star center hole. Confirm your deck size is 42 inches and your mower model appears in the list above (e.g., Troy-Bilt Pony, Super Bronco; Cub Cadet XT1, XT2, ZT1, RZT-42, LT42, LTX1040; Craftsman T110, T1200). This is an aftermarket blade, not OEM Cub Cadet, so check that your spindle pattern matches a 5-point star (not a 6-point or oval). Also verify your blade bolt size (typically 5/8” or 3/4”)—these blades do not include hardware.

Key Things to Know

• Quality: Made from heat-treated steel; reviews note they hold an edge well for regular residential use but may dull faster than OEM on heavy or sandy soil.
• Installation: Moderate difficulty—requires lifting the mower, removing the deck, and using a torque wrench. Always disconnect the spark plug first.
• Common gotcha: These are mulching blades, not standard lift blades. They have a curved, wing-like design that keeps clippings circulating. If you bag or side-discharge, you may need a different blade type.
• Balance: Some users report needing to rebalance the blades out of the box; check with a blade balancer before installing.

Should You Buy It

Yes, if you own one of the listed 42-inch deck tractors or zero-turns, want an affordable mulching upgrade, and are comfortable with basic mower maintenance. Skip if you primarily bag or discharge, or if you need OEM-specific fitment for warranty or vibration-free operation.
