I have a mid 1990's John Deere Round Hay Baler. We have gotten about 100 bales done this year so far. The baler just recently started having a problem of the three belts on the right side (looking at it from the back) have begun walking. The belt on the right and the one on the left try to walk over the top of the third one in the middle. If you don't shut the baler off they will flip the belts. We have checked all the bearings and they are all good. Im not sure what the problem could be. Any help or suggestions that anyone could give would be greatly appreciated. Thanks!!!!!!![/b]
