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 9 PACK

What It Is

This is a 9-pack of 50-inch deck mower blades designed for residential and semi-commercial zero-turn and lawn tractors from Cub Cadet, Troy-Bilt, and MTD brands. They replace OEM part numbers 742-05052 and 942-05052, offering a cost-effective bulk option for frequent mowing on large properties.

Fitment & Compatibility

Before buying, confirm your deck measures exactly 50 inches (not 46 or 54). These blades fit Cub Cadet models: ZT1-50, RZT-50, XT1-LT50, ZT2-50, XT2-LX50, LTX 1050, and Troy-Bilt Super Bronco/Mustang XP 50-inch zero turns. Check your blade’s length (approx. 20.5 inches), center hole diameter (usually 1 inch), and offset (typically 0.75–1 inch) against OEM specs. These are aftermarket replacements—verify your spindle bolt pattern matches (usually 5-point star or 3-hole). Not for 42- or 46-inch decks.

Key Things to Know

• Quality vs OEM: These are budget-friendly aftermarket blades. Expect slightly softer steel than OEM Cub Cadet blades, meaning faster dulling on rocky or sandy soil.
• Installation difficulty: Easy—just a socket wrench and jack/ramps. Torque bolts to 70–90 ft-lbs. Check blade balance after mounting; some users report minor weight inconsistencies.
• Common gotcha: The 9-pack includes 3 sets of 3 blades. For most 50-inch decks (3-blade spindles), that’s exactly 3 full replacements—good for 3 seasons or heavy use.
• Shipping note: Blades come bundled—may arrive scratched or with small surface rust. Wipe down and sharpen before first use if needed.

Should You Buy It

Buy this if you have a compatible 50-inch Cub Cadet/Troy-Bilt mower, mow over 2 acres weekly, and want a bulk supply to swap blades without reordering. Skip it if you mow fine turf (e.g., golf course lawns) or need premium edge retention—OEM blades last longer between sharpenings for about the same per-blade cost.
