UDC Parts 954-05021 Deck Belt Replacement for Cub Cadet 42 Inch XT1 LT42 XT2 LX42 Craftsman T210 CMXGRAM1130043 T2200 MTD 754-05021 Columbia 13APA1KS897 Lawn Mowers/Aramid Cord / 99.75 inch

What It Is

This is a 99.75-inch, aramid-cord replacement deck belt for 42-inch cutting decks on select Cub Cadet, Craftsman, MTD, and Columbia lawn tractors. It drives the blades from the engine pulley and is a direct aftermarket substitute for OEM part 754-05021.

Fitment & Compatibility

Before buying, confirm three things:

1. Deck size: Must be a 42-inch deck. This belt will not fit 46-inch or 50-inch decks.
2. Model number: Verified compatible with Cub Cadet XT1 LT42, XT2 LX42, Craftsman T210, T2200, CMXGRAM1130043, MTD 754-05021, and Columbia 13APA1KS897. Check your mower’s model tag (usually under seat or on frame) against the seller’s list.
3. Measurements: OEM belt length is 99.75 inches (5/8-inch width). Measure your old belt or the deck pulley path to confirm. If your original belt is frayed or stretched, this length is correct.

Note: Aftermarket belts can vary slightly in tension. If the belt is loose after installation, you may need to adjust the tensioner or replace idler pulleys.

Key Things to Know

• Quality: Aramid cord is stronger than standard rubber/cord belts—good for longevity, but not as flexible as Kevlar. Expect 2–3 seasons with normal use.
• Installation difficulty: Moderate. You’ll need a wrench to remove the deck, reroute the belt around pulleys, and re-tension. A belt routing diagram (usually on deck or manual) is essential.
• Common gotcha: The belt may “flip” if routed incorrectly—double-check the pulley grooves before tightening. Also, worn idler pulleys can cause premature belt wear; replace them if rough or loose.
• Price vs OEM: At ~$23, it’s roughly half the cost of a genuine Cub Cadet belt. Reviews (4.3/5 over 12,700+) suggest reliable performance for most homeowners.

Should You Buy It

Yes, if you have a listed 42-inch Cub Cadet, Craftsman, or MTD model and want a cost-effective replacement that matches OEM specs. It’s not for commercial use (frequent belt changes may be needed), but for residential mowing, it’s a solid value. Skip it if you need a belt for a different deck size or want a premium Kevlar option.
