What It Is

This is a 3-pack of aftermarket mulching blades designed for 50-inch cutting decks on select Cub Cadet and Troy-Bilt lawn tractors. They replace OEM part numbers 742-04053A, 942-04053A, 742-04056, and 942-04056, and include the necessary hardware (bolts, washers, lock washers) for installation.

Fitment & Compatibility

Before buying, measure your deck size—these only fit 50-inch decks. Confirm your model is on the list: Cub Cadet LT1050, LT1550, LTX1050, SLT1550, or Troy-Bilt RZT50. Check the original blade’s part number on the blade itself (stamped into the metal) to verify it matches one of the OEM numbers above. These are aftermarket blades, not genuine Cub Cadet parts, so the coating or steel thickness may differ slightly. Always ensure the blade center hole diameter and overall length match your old blade.

Key Things to Know

• Mulching vs. bagging/discharge: These are mulching blades (more curve, higher lift) designed to chop clippings finer. They work poorly for bagging or side-discharge—use OEM high-lift blades for those tasks.
• Installation difficulty: Easy—remove old blade, install new one with included hardware. Torque bolts to 70–90 ft-lbs. Use a thread-locker if not pre-applied.
• Common gotcha: The included hardware may be slightly different thread pitch or length than OEM. Test-fit before tightening. If bolts don’t seat flush, reuse your original hardware.
• Performance: Expect decent mulching in dry grass. Wet or tall grass may clog more than OEM blades.

Should You Buy It

Buy this if you have a compatible 50-inch Cub Cadet or Troy-Bilt mower, want a budget-friendly mulching blade set, and don’t need to bag or discharge clippings. Skip it if you require genuine OEM parts, need high-lift blades for bagging, or have a different deck size.
