(3 Pack) 942-04053C Lawn Mower High Lift Blades Replacement for MTD/Cub Cadet/Troy-Bilt 942-04053B 742-04053 942-04056C Toro 112-0316, Fits Cub Cadet LT1050, LTX1050, RZT50 for 50'' Deck Mower

What It Is

This is a 3-pack of high-lift replacement blades designed to increase airflow and suction under the deck for better grass clipping discharge and bagging performance. They are intended for 50-inch cutting decks on select MTD, Cub Cadet, Troy-Bilt, and Toro lawn tractors.

Fitment & Compatibility

Before buying, confirm your mower has a 50-inch deck and that the OEM blade part number is one of these: 942-04053B, 742-04053, 942-04056C, or Toro 112-0316. This set replaces those numbers. Measure your existing blade—these are 20.5 inches long, with a 1-inch center hole and a 0.25-inch thickness. They fit models like the Cub Cadet LT1050, LTX1050, and RZT50, but also many Troy-Bilt and MTD 50-inch deck tractors. Check your owner’s manual or current blade part number to be sure; cross-referencing with a brand-specific parts diagram is recommended.

Key Things to Know

• High-lift design: These blades create strong upward airflow. This improves bagging and side discharge but increases engine load and can cause more wear on the deck and belt if used on thick, wet grass.
• Installation difficulty: Moderate. You’ll need a socket wrench and a torque wrench (tighten to 45-55 ft-lbs). Always lift the mower safely, disconnect the spark plug, and wear gloves—blade edges are sharp.
• Balance check: Even though they come as a set, it’s smart to balance each blade before installing. An unbalanced blade causes vibration, cuts unevenly, and can damage the spindle.
• Common gotcha: These are not for mulching. If you want to leave clippings on the lawn, you need a mulching blade or a separate mulching kit. High-lift blades are best for bagging or in dry conditions.

Should You Buy It

Buy this set if you own a 50-inch deck Cub Cadet, Troy-Bilt, or MTD tractor that uses the listed OEM blade numbers and you primarily bag or side-discharge grass. At $24.99 for three blades (a good value compared to OEM singles), they’re a solid choice for replacing worn or dull blades. Skip them if you need mulching blades or if your deck size is different.
