What It Is

This MAXPRO 3-pack of mulching blades is designed for 50-inch cutting decks on Cub Cadet RZT 50 and LTX 1050 zero-turn and lawn tractors, as well as compatible Troy-Bilt and MTD models. They replace OEM part numbers 942-04053A, 742-04053C, 742-04053A, 742-04053, 942-04053, and 942-04053C.

Fitment & Compatibility

Before buying, confirm your deck is exactly 50 inches (not 46" or 54"). Measure blade length: OEM is 20.5 inches with a 1-inch center hole and 0.5-inch offset. Check your model number on the tractor’s data tag—this set fits Cub Cadet RZT 50 (2010+), LTX 1050, and some Troy-Bilt Super Bronco 50 and MTD 50-inch decks. It does not fit older Craftsman, Husqvarna, or John Deere models. Always verify your existing blade’s part number against the list: 942-04053A, 742-04053C, 742-04053A, 742-04053, 942-04053, 942-04053C.

Key Things to Know

• Quality vs. OEM: Made from heat-treated steel with a painted finish. They’re slightly thinner than factory Cub Cadet blades—expect faster wear under heavy use, but fine for residential mowing.
• Installation: Remove the center bolt with a 15/16" socket (impact wrench helps). Torque to 70-90 ft-lbs when reinstalling. Use thread locker if bolts are reused.
• Mulching vs. Bagging: These are dedicated mulching blades with a higher lift curve—they’ll chop clippings finer but won’t bag well. Switching to bagging? Keep OEM blades.
• Balance Check: Unbox and check each blade’s balance on a balancer before mounting. A few users report slight imbalance; file the heavy side if needed.

Should You Buy It

Buy this set if you have a 50-inch Cub Cadet RZT 50 or LTX 1050 and want affordable mulching blades for a season or two of residential mowing on standard grass. Avoid if you need OEM-grade durability for commercial use, bagging performance, or if your deck isn’t exactly 50 inches. At $32.99 for three blades, it’s a solid value for the price.
