942-05052A Medium Lift Lawn Mower Blades, 742-05052A 2-in-1 Blades Compatible with MTD/Cub Ca det/Troy-Bilt 50" Cut, Fit for S50 XT1 GT50 LT50 XT2 Mowers, Replace 330-052/15454, 3 Pack

What It Is

This is a 3-pack of medium-lift lawn mower blades for 50-inch cutting decks, designed for mulching, bagging, and side-discharge use. They fit MTD, Cub Cadet, and Troy-Bilt tractors like the S50, XT1, GT50, LT50, and XT2 series.

Fitment & Compatibility

Before buying, confirm your mower deck measures exactly 50 inches (not 46" or 54"). These blades replace OEM part numbers 330-052, 15454, 942-05052A, and 742-05052A. They are aftermarket, not genuine MTD/Cub Cadet, but match the same length and hole pattern. Check your current blade’s length (should be ~20.5 inches) and center hole diameter (typically 1 inch). Not compatible with zero-turn or 42"/46" decks.

Key Things to Know

• Medium lift balances cutting performance and engine load—good for typical grass, not heavy weeds or tall wet grass.
• Installation: Use a torque wrench (40-50 ft-lbs) and thread locker on the blade bolt. Sharpening is possible but these are inexpensive enough to replace as a set.
• Common gotcha: The 3-pack includes only blades, no hardware. Reuse your existing washers and bolts, or buy new ones if worn.
• Quality: Rated 4.7 stars from 26 reviews—users note they cut well out of the box and balance decently, but a few report needing minor balancing.

Should You Buy It

If you own a 50-inch MTD/Cub Cadet/Troy-Bilt tractor and want a budget-friendly 3-pack for regular seasonal replacement, these are a solid value. Not for heavy-duty commercial use or non-standard deck sizes.
