What It Is

This is a set of two 50-inch 2-in-1 (mulching/discharge) mower blades designed for select Cub Cadet and Troy-Bilt zero-turn mowers with a 50-inch deck. They use a 6-point star center hole and are a direct replacement for OEM part numbers 942-04053A, 742-04053A, and 742-04053C.

Fitment & Compatibility

Before buying, confirm your deck is exactly 50 inches. These blades fit Cub Cadet RZT 50, LTX1050VT, LTX1050KH, i1050, and LT1050 zero-turn models, plus Troy-Bilt Mustang XP with a 50-inch deck. The 6-point star center hole is critical—measure your existing blade’s center hole shape. These are not compatible with round-hole or oval-hole spindles. Also verify the blade length is 16.5 inches (cutting diameter 50 inches total for the pair). Check your mower’s deck model number (usually stamped under the seat or on the deck itself) to avoid returns.

Key Things to Know

• Quality: These are aftermarket blades but match OEM specs. Expect decent steel thickness (about 0.20 inch) and a pre-sharpened edge. Not heavy-duty for rocky or rough terrain.
• Installation: Simple—jack up the deck, remove the center bolt, swap blades, torque to 70-90 ft-lbs. Use a block of wood to prevent spindle rotation. No special tools beyond a socket and torque wrench.
• Gotchas: The 2-in-1 design means they’re optimized for both mulching and side discharge, but they won’t mulch as finely as dedicated mulching blades. Ensure the blade orientation (air lift up) matches your old blades—they’re not symmetrical.
• Common issue: Cub Cadet and Troy-Bilt decks may have different spindle shaft diameters—these fit standard 5/8-inch shafts. Measure yours before buying.

Should You Buy It

If you own a compatible Cub Cadet or Troy-Bilt 50-inch zero-turn and need a budget-friendly, OEM-matching replacement for regular residential mowing, this is a solid pick. Avoid if you need heavy-duty blades for commercial use or professional-grade mulching performance—look for a dedicated mulching blade set instead.
