1/2 x 162 Inch 954-04240 754-04240 Lawn Mower Deck V Belt for Cub Cadet LTX 1050 Series-LTX1050KH LTX1050KW LTX1050VT SLTX1050 with 50 Inch MTD Craftsman PYT9000 YT950KH OCC-754-04240 (Aramid Cord)

What It Is

This is a 1/2" x 162" Aramid cord V-belt designed to drive the mower deck blades on select Cub Cadet, MTD, and Craftsman lawn tractors with a 50-inch cutting deck. It replaces OEM part numbers 954-04240 and 754-04240.

Fitment & Compatibility

• Deck size: Only for 50-inch decks. Measure your belt—if it’s not 162" long or 1/2" wide, this won’t fit.
• Primary models: Cub Cadet LTX 1050 series (LTX1050KH, LTX1050KW, LTX1050VT, SLTX1050). Also fits some Craftsman PYT9000, YT950KH, and MTD models with the same belt spec.
• OEM cross-reference: Replaces OEM 954-04240 and 754-04240. Verify your machine’s OEM part number before ordering.
• Aftermarket: This is an aftermarket belt with Aramid cord (stronger than standard rubber). Check that your deck uses a single V-belt (not a double or Kevlar-reinforced belt).

Key Things to Know

• Aramid cord construction is more durable than standard rubber belts, resisting stretching and heat better—good for heavy-duty mowing.
• Installation difficulty: Moderate. You’ll need to remove the deck or at least the belt cover, release tension from the idler pulley, and route the belt per your deck diagram. Allow 30-45 minutes.
• Common gotcha: The 162" length must match exactly—a belt 1" too long or short will slip or cause poor blade engagement. Measure your old belt end-to-end (flat) to confirm.
• Break-in period: Expect slight initial stretching; re-check tension after the first hour of use and adjust if needed.

Should You Buy It

Buy this if you own a Cub Cadet LTX 1050 with a 50-inch deck and want a cost-effective upgrade over basic rubber belts. The Aramid cord adds durability for frequent or tough mowing. Avoid if your deck uses a different belt length or you need an exact OEM match—verify fitment first.
