What It Is

The GX21833 is a 1/2" x 141" V-belt that drives the blades on 48-inch mower decks. It’s a direct replacement for OEM belts on Cub Cadet, Toro, Troy-Bilt, John Deere, and other lawn tractors with a 48-inch cutting width.

Fitment & Compatibility

Before buying, confirm your deck size is exactly 48 inches and measure your old belt length (must be 141 inches). This belt cross-references with OEM numbers 754-05008, 954-05008, 119-8820, 114-0453, and 07217400, plus aftermarket Gates 68141 and Goodyear 841141. It fits popular models like Cub Cadet LTX 1046, Toro TimeCutter, Troy-Bilt Super Bronco, and John Deere D140/LA145 (48" deck). Check your owner’s manual or existing belt part number—don’t rely on brand name alone, as deck designs vary.

Key Things to Know

• Quality: Aftermarket belt, not OEM, but uses Kevlar cord and rubber construction similar to Gates/Goodyear. Holds up well under normal residential use.
• Installation: Moderate difficulty. You’ll need to remove the deck or release the tensioner pulley. Take a photo of the belt routing before removing the old one.
• Common gotcha: This belt is for 48-inch decks only. Using it on a 42- or 46-inch deck will cause slippage or premature wear. Also, verify your deck uses a single belt (not a dual-belt system).
• Price point: At ~$19, it’s about half the cost of OEM belts. A good value if you don’t need a dealer-specific part.

Should You Buy It

Yes, if you need a reliable, budget-friendly replacement for a 48-inch deck belt on a Cub Cadet, Toro, Troy-Bilt, or John Deere lawn tractor. Avoid it if you prefer OEM-only parts for commercial use or if your deck requires a different length. For residential mowing, this belt offers solid durability at a low price.
