8TEN Deck Blade Belt Kit for Cub Cadet MTD Troy Bilt LT1050 LGT1050 i1050 SLT1550 TB2450 Super Bronco 50 inch Deck

What It Is

This is a 3-blade belt kit designed for 50-inch deck lawn tractors from Cub Cadet, MTD, and Troy-Bilt. It replaces the OEM deck drive belt and three cutting blades, saving you from buying each part separately.

Fitment & Compatibility

• Deck size: Only fits 50-inch cutting decks. Measure your deck’s blade tip-to-tip width to confirm.
• Models: Works with Cub Cadet LT1050, LGT1050, i1050; Troy-Bilt Super Bronco, TB2450; MTD SLT1550 and similar 50-inch deck tractors from these brands.
• OEM vs. aftermarket: This is an aftermarket kit, not OEM. Check your original belt part number (often 954-05090 or 754-05090) and blade part numbers (typically 942-0764 or 742-0764) to verify cross-reference.
• Measurements: Belt is a 1/2" x 96.5" Kevlar-reinforced V-belt. Blades are 16.5" long with a 1" center hole and 0.75" diameter spindle hole. Confirm your spindle size matches.

Key Things to Know

• Quality concerns: Some users report belt life shorter than OEM (1–2 seasons vs. 3–4). Inspect belt for fraying after heavy use.
• Installation difficulty: Moderate. You’ll need a socket set, jack or blocks to lift the deck, and a blade removal tool. Allow 1–2 hours.
• Blade sharpness: Blades come pre-sharpened but may need balancing. Check with a blade balancer before installing to avoid vibration.
• Fitment gotchas: On some Cub Cadet models, the belt routing requires a specific diagram—take a photo of your old belt path before removal.

Should You Buy It

This kit is a solid value if you need both blades and a belt at once and are comfortable with DIY installation. It’s best for budget-conscious owners who don’t mind potentially replacing the belt sooner than OEM. If you want maximum durability or have a commercial-use mower, stick with genuine Cub Cadet parts.
