This is a John Deere 6620 sidehill. I had noticed a slight "thump, thump, thump" from the rear end. I took the left wooden block off of one of the five auger shafts under the straw walkers and found that the hollow tubular shaft was only half there. So, when the tubular shaft turns it is sort of dropping up and down in the wood block. I think the wood block was sort of worn and allowed the hollow shaft to be cut on the sheet metal that holds the wooden bearings. So, I have some questions. Does the pan that the augers sit in hinge up front drop down in the rear? I really doubt that it does. Can the augers be pulled out without taking the rear hood or other side sheets off??? If it ends up being a time consuming project I am just going to put a tight fitting shaft into the auger tube, weld it, and make a new wooden block with a hole the size of the new inserted shaft. Any ideas on the proper removal and repair are appreciated. Thank you.
