Good To Know

Q: How often should I replace the deck drive belt on my John Deere X350? A: Inspect the belt every 50 hours of operation and replace it if you see cracking, glazing, or loss of tension; most users replace it every 2-3 seasons.

Q: Does this belt also fit the 54-inch deck on John Deere X series? A: No, this belt is specifically for 48-inch decks; using it on a different deck size may cause slippage or damage.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
