954-04240 Cub Cadet Deck Mower Belt Replacement for LTX1050 LTX1050VT SLTX1050 50 Inch Deck Belt 754-04240 MTD Toro 86-1960 Heavy Duty Drive Belt 1/2" x 162"

What It Is

This is a heavy-duty replacement drive belt for 50-inch cutting decks on specific Cub Cadet, MTD, and Toro lawn tractors. It connects the engine pulley to the deck spindles to spin the blades, built to handle the higher torque of wider mowing decks.

Fitment & Compatibility

Before buying, verify three things:

• Deck size: This belt is for 50-inch decks only. Do not use on 46-inch or 54-inch decks.
• Model numbers: Direct fit for Cub Cadet LTX1050, LTX1050VT, and SLTX1050. Also fits select MTD and Toro models using OEM part 754-04240 or 86-1960.
• Measurements: Belt is 1/2 inch wide x 162 inches long. Measure your old belt end-to-end (not around pulleys) to confirm length. A 1/2-inch difference can cause slipping or poor engagement.

Cross-reference: Replaces OEM Cub Cadet 954-04240, MTD 754-04240, and Toro 86-1960. If your machine uses a different OEM number, this will not fit.

Key Things to Know

• Quality: 4.3/5 stars from 295 reviews. Users report it lasts 1-2 seasons under normal residential use. Heavy-duty construction resists stretching better than economy belts.
• Installation difficulty: Moderate. You’ll need to remove the deck or at least the belt guard. Use a belt routing diagram (check your manual or Cub Cadet’s site) – misrouting causes blade spin issues.
• Common gotcha: This belt is not for the mower’s drive system (transmission). It drives the blades only. If your mower won’t move, this won’t fix it.
• Tension check: After installing, run the deck at full throttle for 30 seconds, then recheck belt tension. A loose belt can slip and burn.

Should You Buy It

If you own a Cub Cadet LTX1050, LTX1050VT, or SLTX1050 with a 50-inch deck and need a reliable, affordable replacement that matches OEM specs, this belt is a solid choice. Avoid it if your deck is a different size or if you need a transmission drive belt.
