What It Is

This is a 3-pack of 50-inch replacement mower blades designed for select Cub Cadet, Troy-Bilt, and MTD models with a 50-inch deck. They’re intended for residential cutting of grass and light weeds on lawns up to a few acres.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: Only for 50-inch decks. Measure your deck width tip-to-tip if unsure.
• Model fit: Confirmed for Cub Cadet LTX1050, RZT50, and Troy-Bilt Mustang 50. Also fits many MTD-built 50-inch zero-turn and garden tractors. Check your model number against the OEM cross-reference: replaces 742-04056, 942-04056, 942-04053, and 942-05043C.
• Measurements: Blade length must be 20.5 inches center hole to tip, with a 5-point star center hole (1 inch diameter). Thickness is about 0.203 inches. If your existing blade matches these dimensions, these will fit.

Pro tip: Remove one existing blade and compare the length, hole shape, and thickness. Aftermarket blades like these are not exact OEM copies—slight weight or air-lift variations can occur, but dimensional match is the key.

Key Things to Know

• Quality: Made from heat-treated carbon steel with a powder coating. Edge holds up well for 2-3 seasons on standard lawns, but won’t survive rocks or thick brush.
• Installation: Simple bolt-on job. You’ll need a socket wrench and a block of wood to jam the blade. Torque the center bolt to 70-80 ft-lbs. No special tools required.
• Gotcha: These are straight blades (not mulching or high-lift). They’ll discharge and bag fine but won’t give a fine mulch. If you want mulching, buy dedicated mulching blades.
• Set includes: 3 blades. If your deck uses 3 blades (common on 50-inch decks), this is a full set. If your deck uses 2 blades, you’ll have a spare.

Should You Buy It

Buy this if you have a 50-inch Cub Cadet, Troy-Bilt, or MTD residential mower and want a budget-friendly, drop-in replacement that matches OEM dimensions. It’s a solid value for standard cutting and bagging. Skip it if you need mulching blades, have a different deck size, or mow rough terrain that could bend cheap steel.
