What It Is

This is a 46-inch deck drive belt for MTD/Cub Cadet tractors, specifically designed for XT1 and XT2 Enduro Series (LT46, LT46 KH, LX46, LX46 KW) and ZT1/ZT2 Ultima Series zero-turn mowers. It transfers power from the engine pulley to the deck spindles to spin the blades.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: Must be a 46-inch deck. This belt will not fit 42-inch or 50-inch decks.
• Model series: Confirmed fit for XT1-LT46, XT2-LT46, ZT1, ZT2 Ultima. Check your model tag (under seat or on frame) for exact suffix (e.g., KH, KW).
• OEM cross-reference: Replaces OEM part numbers 490-501-C063, 954-05022, and 754-05022. If your original belt has a different number, measure length (approx. 92.5 inches) and width (1/2 inch) to confirm.
• Aftermarket note: This is a non-OEM belt. It should work, but some users report slightly shorter lifespan than the genuine Cub Cadet belt.

Key Things to Know

• Installation difficulty: Moderate. You’ll need to remove the deck (4 pins/bolts) and route the belt around three spindles and the tensioner. A diagram is helpful—take a photo before removing the old belt.
• Quality: Most users find it adequate for residential use (1-2 acres). For heavy commercial use, consider the OEM belt for longer wear.
• Common gotcha: The belt may be slightly tight on the tensioner. You might need to release the tensioner arm with a wrench to slide it on. Do not force it.
• Warranty: This aftermarket belt usually comes with a 90-day warranty. OEM belts often have 1-2 years.

Should You Buy It

Buy this if you have a 46-inch Cub Cadet XT1/XT2 or ZT1/ZT2 and need a cost-effective replacement for light-to-moderate residential mowing. It’s a solid value at $25, but if you mow frequently or have tough conditions, spend $10-15 more on the OEM belt for better durability and fit.
