942-04308-X 42" Mulching Toothed Mower Blades for Cub Cadet MTD Troy-Bilt Bronco Pony Mustang for XT1 XT2 LT42 RZT 42 inch Deck Zero Turn Lawn Tractor for 942-04308 942-04126 6-Point Star Blades

What It Is

This is a set of three mulching toothed blades designed for 42-inch cutting decks on select Cub Cadet, MTD, and Troy-Bilt lawn tractors and zero-turn mowers. They replace OEM part numbers 942-04308 and 942-04126, and are intended for mulching grass clippings into fine particles rather than bagging or side-discharging.

Fitment & Compatibility

Before buying, verify your mower has a 42-inch deck and uses a 6-point star center hole pattern. This blade set fits many Cub Cadet XT1, XT2, LT42, RZT, and similar models from MTD, Troy-Bilt (Bronco, Pony, Mustang), and Yard Machines. Measure your existing blades: these are approximately 20.5 inches long, 2.5 inches wide, with a 0.25-inch thickness and a 7/8-inch diameter center hole. Cross-reference your mower’s model number with the 942-04308 or 942-04126 OEM numbers to confirm. Not all 42-inch decks share the same blade—check the star pattern and length.

Key Things to Know

• Quality: Made from hardened steel with a painted finish; reviews note they hold an edge well for residential use but may dull faster than premium brands on rocky or sandy soil.
• Installation: Moderate difficulty—requires lifting the mower safely (use ramps or jack stands), removing the three blades, and torquing to manufacturer specs (typically 70–90 ft-lbs). A torque wrench is recommended.
• Mulching performance: The toothed design lifts and recuts clippings, but works best with a mulching plug installed and dry grass; wet or tall grass may clump.
• Common gotcha: Blades may be slightly thicker than OEM, causing rubbing on some decks—test fit before tightening fully. Also, always replace all three blades as a set to maintain balance.

Should You Buy It

This is a solid budget-friendly option for homeowners with a compatible 42-inch Cub Cadet, MTD, or Troy-Bilt tractor who want effective mulching without paying OEM prices. If you mow large, rough areas or need maximum durability, consider a thicker premium blade. For typical residential lawns, this set delivers good value and performance.
