CUB CADET 954-05087A A-Sec 108.3" Deck V-Belt Enduro XT1-LT46 XT2-LX46 Lawn Garden Tractors

What It Is

This is a genuine OEM Cub Cadet V-belt (part #954-05087A) that drives the mower deck blades on select 46-inch deck Enduro Series and XT Series lawn tractors. It’s specifically designed for the 108.3-inch deck belt routing on Cub Cadet XT1-LT46, XT2-LX46, and compatible A-Sec models.

Fitment & Compatibility

Before buying, verify three things:

• Deck size: Must be a 46-inch mower deck (not 42” or 54”).
• Model series: Works with Cub Cadet XT1 (LT46) and XT2 (LX46) Enduro tractors. Also fits some A-Sec variants – double-check your owner’s manual or existing belt part number.
• OEM vs aftermarket: This is a genuine Cub Cadet belt, not a generic replacement. Aftermarket belts may be cheaper but often differ in length, width, or material quality, causing slipping or premature wear.
• Measurements: Belt length is 108.3 inches (outside circumference), 1/2-inch width. If your old belt measures differently, it won’t fit.

Key Things to Know

• Quality: Genuine OEM belt has reinforced Kevlar cords for longer life and better grip than most aftermarket belts.
• Installation difficulty: Moderate. You’ll need to remove the mower deck, release the belt tensioner, and route the belt around all pulleys per the diagram. A belt routing diagram is often printed on the deck.
• Common gotcha: The belt must be routed exactly as shown – wrong routing causes slipping or blade disengagement. Take a photo of the old belt before removal.
• Price vs value: At ~$71, it’s pricier than some aftermarket options, but you get guaranteed fit and durability. A cheap belt may fail in one season.

Should You Buy It

If you own a Cub Cadet XT1-LT46 or XT2-LX46 with a 46-inch deck and want a belt that fits perfectly and lasts, this is the right choice. It’s also ideal if you’re replacing a worn OEM belt and want the same performance. If you’re on a tight budget or have a different brand/model, look for an aftermarket belt with verified measurements.
