New John Deere 48 inch Deck Drive Belt p/n GX21833. We found these in an inventory we purchased recently. Brand new never installed does have some dust on them from being stored in a warehouse setting but are still pliable. The added Kevlar cords provide strength for higher horsepower needs. We believe that this belt will fit on John Deere models D140, D150, D155, D160, LA145, LA155, LA165, LA130, LA140, Z255 and Z355E (model serial number -050000).
