Stens OEM Replacement Belt 265-435 Compatible with Cub Cadet XT1-LT42 and XT2-LX42 with 42" Deck, MTD 42" Deck, 2015 & 2016 754-05021, 754-05021A, 954-05021, 954-05021A

What It Is

This is a replacement drive belt for 42-inch cutting decks on Cub Cadet XT1-LT42 and XT2-LX42 lawn tractors (model years 2015–2016), plus other MTD-built 42-inch decks. It connects the engine pulley to the spindle and blade system, enabling the blades to spin.

Fitment & Compatibility

Before buying, confirm your deck is exactly 42 inches (measured blade tip to blade tip) and that your tractor is a Cub Cadet XT1-LT42 or XT2-LX42 with a 42" deck, or an MTD 42" deck from 2015–2016. Cross-reference OEM part numbers: 754-05021, 754-05021A, 954-05021, 954-05021A. This Stens belt is an aftermarket OEM replacement—not genuine Cub Cadet, but built to factory specs. Measure your old belt’s length (should be about 94.5 inches) and width (1/2 inch) to verify. Belts wear over time; if yours is cracked, glazed, or stretched, replacement is due.

Key Things to Know

• Quality: Stens is a reputable aftermarket brand—this belt is Kevlar-reinforced and matches OEM durability. Most users report it lasting 2–3 seasons with regular use.
• Installation: Moderate difficulty. You’ll need to remove the deck (usually two pins and a belt tensioner release) and route the belt around pulleys per your deck diagram. A belt tool or long screwdriver helps with tension.
• Common gotcha: If your deck has a spring-loaded idler, ensure the belt is seated correctly in the pulley grooves—misrouting causes premature wear or blade slippage. Also, check spindle bearings: a seized spindle can destroy a new belt quickly.
• Price vs. OEM: At ~$23, it’s roughly half the cost of a genuine Cub Cadet belt, and reviews suggest comparable life.

Should You Buy It

If you own a Cub Cadet XT1-LT42 or XT2-LX42 (2015–2016) with a 42" deck and need a reliable, budget-friendly replacement that matches OEM performance, this belt is a solid choice. It’s less suitable for older or non-MTD decks—always verify fitment first.
