50" Deck Mower Blades Fit for Cut MTD Cub Cadet ZT1-50 RZT-50 XT1-LT50 ZT2-50 XT2-LX50 LTX 1050 Troy-Bilt Super Bronco Mustang XP 50 inch Zero Turn Mower Replaces OEM 742-05052 942-05052 6 PACK

What It Is

This is a 6-pack of 50-inch lawn mower blades designed for MTD, Cub Cadet, Troy-Bilt, and other zero-turn or riding mowers with a 50-inch cutting deck. They replace OEM part numbers 742-05052 and 942-05052, and are suited for residential or light commercial use.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 50 inches (measured blade tip to tip). These blades fit Cub Cadet ZT1-50, RZT-50, XT1-LT50, ZT2-50, XT2-LX50, LTX 1050, and Troy-Bilt Super Bronco/Mustang XP 50-inch models. They are an aftermarket replacement for OEM parts 742-05052 and 942-05052. Measure your existing blade length (likely 20.5 inches), width (2.5 inches), center hole diameter (typically 5/8 inch), and thickness (0.25 inches). If your mower uses a different spindle or blade mount (e.g., 3-point star), these won’t fit. Check your owner’s manual or existing blade for exact specs.

Key Things to Know

• Quality: Made from hardened steel with a balanced design, but aftermarket blades may wear faster or be less durable than OEM. Check reviews for balance issues out of the box.
• Installation: Easy with basic tools (socket wrench, jack stands). Lift the mower safely, remove the center bolt (usually 5/8-inch), and replace one blade at a time. Torque to 60-70 ft-lbs.
• Common Gotcha: The 6-pack is for a 3-blade deck—you get two sets of three. Don’t assume all six are needed at once. Verify your deck uses 3 blades (most 50-inch decks do) and that the blade orientation (cutting edge direction) matches your mower’s rotation.
• Fitment Check: Double-check deck depth and spindle clearance—some decks require a different blade offset (e.g., low-lift vs. high-lift). These are typically medium-lift, fine for most grass types.

Should You Buy It

If you own a compatible 50-inch MTD/Cub Cadet/Troy-Bilt zero-turn or riding mower and want a budget-friendly replacement for regular mowing (not heavy-duty or mulching), this 6-pack is a solid value. For commercial use or tougher conditions (thick, wet grass), consider OEM blades for longer life. Verify fitment with your specific model and blade measurements before ordering.
