The 200 series John Deere mowers came in three sizes: 212, 214 and 216. The 212 series was the smallest and the 216 was the largest. The deck belt is the same for all three of the 200 series mowers.
The belt needed for the John Deere 214 mower deck is an after-market belt, meaning its not manufactured any longer by John Deere or any of its original parts OEM manufacturers. The size of the belt is 17/32 inches wide by 80-1/8 inches long.
John Deere has two deck sizes for the 200 series of mowers: 38 and 39 inches cut. The size of the deck is based on the amount of grass area the blade of the mower cuts. The belt fits both deck sizes.
Because the belt is manufactured after-market, ensure the retailer or part manufacturer sells quality parts. A John Deere authorized dealer may have the belt or suggest where to order the belt. Authorized dealers also sell used parts and equipment.
