MowerPartsGroup (3) Reaper Mulching Blades Compatible with Cub Cadet 50" 742-04053 Made in USA

What It Is

This is a set of three mulching blades designed for 50-inch Cub Cadet zero-turn and lawn tractors. They replace OEM part 742-04053 and are made in the USA, intended for cutting grass into fine clippings that decompose quickly.

Fitment & Compatibility

Before buying, confirm your deck is exactly 50 inches—measure deck width, not the cut path. These blades fit select Cub Cadet models (e.g., RZT 50, LTX 1050, XT1/XT2/XT3 series with 50" decks) and some MTD-built equivalents. Check your current blade part number against OEM 742-04053; if it matches, these fit. Measure blade length (likely 18.5 inches), center hole diameter (usually 1 inch), and thickness (approx. 0.25 inches). Verify the blade shape—mulching blades have a curved, serrated design—and ensure they’re not for side-discharge or bagging use. Aftermarket blades may vary slightly in weight or balance, so confirm your spindle pattern matches.

Key Things to Know

• Quality: Made in USA from heat-treated steel; users report good durability but some note slight balance differences from OEM.
• Installation: Moderate difficulty—requires a socket set and torque wrench (blade bolts typically 70-90 ft-lbs). Lift mower safely, block wheels, and disconnect spark plug.
• Gotchas: Mulching blades work best with high engine RPM and dry grass; wet or tall grass may clog. Check for deck clearance—these blades are thicker than some OEM versions.
• Performance: Fine mulching action reduces bagging frequency, but may leave clumps in damp conditions.

Should You Buy It

Buy these if you own a Cub Cadet 50" deck, want USA-made blades, and prioritize mulching over bagging or side-discharge. They’re a solid mid-range choice for homeowners seeking durable, cost-effective replacements, but skip them if you need OEM exactness or run a commercial operation with heavy daily use.
