954-05021 Deck Belt 1/2'' x 100'' for Cub Cadet XT1-LX42, XT2-LX42, Craftsman T210, MTD, Poulan Pro 42 inch Deck Belt, Replaces 954-05021 Deck Belt Cub Cadet 754-05021

What It Is

This 1/2-inch wide by 100-inch long deck belt transfers power from the engine pulley to the mower blades on specific 42-inch cutting decks. It’s designed for Cub Cadet XT1-LX42 and XT2-LX42 models, plus Craftsman T210, MTD, and Poulan Pro 42-inch decks.

Fitment & Compatibility

Before buying, confirm three things:

• Deck size: Must be exactly 42 inches. This belt does not fit 46-inch or 50-inch decks.
• Model number: Works on Cub Cadet XT1-LX42 (e.g., 13APA1CT056) and XT2-LX42 (e.g., 13WPA1CT009). Also fits Craftsman T210 (917.289200), MTD 42-inch decks, and Poulan Pro 42-inch models. Check your owner’s manual or current belt part number.
• OEM vs aftermarket: This is a genuine Cub Cadet OEM replacement (part 954-05021, also supersedes 754-05021). Aftermarket belts may vary in material and length tolerance—measure your old belt end-to-end to confirm 100 inches.

Key Things to Know

• Quality: OEM belt is reinforced rubber with good resistance to heat and stretching. Expect 2-3 seasons of normal residential use.
• Installation difficulty: Moderate. You’ll need a socket wrench to release the idler pulley tension. No special tools required, but the belt routing diagram on the deck is your friend.
• Common gotcha: If the belt squeals or slips after install, check that the idler pulley moves freely and the belt is seated in all pulley grooves. A worn tensioner spring can cause premature belt wear.
• Double-check the part number: Some 42-inch decks use a 92-inch or 105-inch belt. Using the wrong length will either not reach or cause excessive slack.

Should You Buy It

Buy this if you own a Cub Cadet XT1-LX42 or XT2-LX42, Craftsman T210, or MTD/Poulan Pro 42-inch deck and need a direct OEM replacement with proven fit. It’s a solid choice for reliability and price, but skip it if your deck is a different size or you’re looking for a heavy-duty aftermarket belt for commercial use.
