50" Rotary 15454 Lawn Mower Blade Set Cub Cadet 942-05052A LZ50 Massey MF50-22ZT

What It Is

This is a set of three 50-inch rotary mower blades designed for zero-turn and commercial lawn tractors. They replace worn or damaged blades to restore a clean, even cut on medium-to-large turf areas.

Fitment & Compatibility

Before buying, confirm three things:

1. Deck size: This set fits 50-inch cutting decks only. Measure your deck if unsure.
2. Model cross-reference: Compatible with Cub Cadet 942-05052A (OEM), LZ50, Massey Ferguson MF50-22ZT, and several other 50-inch zero-turn models. Check your owner’s manual or existing blade part number.
3. Measurements: Each blade is roughly 20.5 inches long, with a 1-inch center hole and 0.5-inch offset. Measure your old blade’s length, hole diameter, and thickness to confirm match. Aftermarket sets may vary slightly from OEM specs.

Key Things to Know

• Quality: High-carbon steel with a protective coating resists rust and holds an edge longer than basic steel blades. Good for residential and light commercial use.
• Installation: Straightforward bolt-on replacement. Use a torque wrench to tighten bolts to 70–90 ft-lbs. Mark blade orientation (cutting edge forward) before removing old ones.
• Gotchas: Always sharpen or replace blades in sets to avoid vibration. Check spindle bearings and belt tension while the deck is off.
• Lift: These are low-lift blades, best for bagging or side-discharge. Not ideal for heavy mulching—consider high-lift blades if mulching is your primary need.

Should You Buy It

If you own a 50-inch Cub Cadet, Massey Ferguson, or compatible zero-turn mower and need a reliable, affordable blade set for standard cutting, this is a solid choice. It delivers good durability and performance for the price, especially for homeowners and light commercial users who mow regularly.
