TENGMUJX 50-inch Mulching Blades 3-Pack for Cub Cadet RZT‑50 LTX1050 — OEM Fit, 0.1875" Thick

TENGMUJX 50-inch deck mulching blades are a 3-pack of heavy-duty replacement blades engineered to restore cutting performance on Cub Cadet and compatible zero-turn and riding mower decks.

If your mower is leaving uneven clippings, struggling with thicker grass, or the deck has dull or damaged blades, these TENGMUJX mulching blades are sized and drilled to match common Cub Cadet/MTD/Troy-Bilt OEM patterns so you can reinstall quickly and resume clean, consistent mowing. Each blade is manufactured to the specified dimensions and mounting pattern to fit 50-inch decks used on a wide range of models, including RZT-50 series and LTX1050 machines.

Will these blades fit my Cub Cadet RZT-50 or LTX1050 mower?

Yes — the blades are made to replace the listed OEM part numbers and match the 6-point star center hole pattern used on many 50-inch Cub Cadet decks. Check your mower’s deck part stamp or owner’s manual to confirm compatibility before ordering.

• Replaces OEM numbers: 742-04053, 742-04053C, 942-04053, 942-04053C and related variants.
• Compatible models include RZT50, RZT50KW, RZT-L50 series, LTX1050 variants and SLTX1050.
• Also fits many Troy-Bilt and MTD/White Outdoor 50" models listed by the manufacturer.

What are the blade dimensions and mounting details?

These TENGMUJX blades follow the same physical specifications used by the OEM for 50-inch decks so they seat correctly and maintain correct blade tip speed for safe cutting. The precise dimensions help preserve deck balance and even cutting when installed in sets of three.

• Blade length: 17 13/16" (overall cutting edge span).
• Thickness: 0.1875" for rigidity and impact resistance.
• Width: 2 1/2" providing robust cutting surface and mulching profile.
• Center hole: 6-point star pattern matching common Cub Cadet/MTD mounting studs.

How do these mulching blades improve mowing performance?

The blades are designed with a mulching profile that lifts and recirculates clippings, allowing finer particle size and better distribution back into the turf. When installed as a matched set, they promote more even results, reduce visible clippings, and can help thatch breakdown by cutting clippings finer.

• Mulching profile keeps clippings in the deck longer for finer chopping.
• Uniform dimensions reduce vibration and maintain deck balance.
• Durable steel thickness resists bending from impacts and extends service life.

How should I install and maintain these replacement blades?

Installation is straightforward if you follow safety steps: disconnect spark plug, raise the deck, and remove the old blades using the correct socket and torque. After mounting, check blade clearance and fastener torque periodically and sharpen as needed to retain cutting quality.

• Always disconnect spark plug before service and wear protective gloves.
• Tighten blade mounting bolts to the mower manufacturer’s torque spec.
• Inspect for damage after hitting rocks or roots; replace if bent or cracked.
• Sharpen periodically to maintain a clean cut and reduce turf damage.

Who is this for: These TENGMUJX 50" mulching blades suit home owners and small property managers who own compatible Cub Cadet, Troy-Bilt or MTD 50-inch zero-turn and lawn tractor decks and need a reliable, OEM-pattern replacement set. They’re intended for anyone seeking improved mulching performance, deck balance, and durable steel blades that match common OEM part numbers for straightforward retrofit and continued mowing efficiency.
