Combines TR 87

Sounds like the rotors are out of balance or you have a rotor belt with a burnt spot on it. Maybe it had a rock in it or something.Don't run it too long that way.

If you speed up and slow down your rotors, the vibration would change as well if the problem was unbalanced rotors. You said it shakes like a walker machine. That sounds like a slower shake to me, you might look over the shoe for a problem. Check the pivot bushings(I've never seen one of these bad though),eccentric bearing and drive shaft. I did run a fixed airfoil chaffer last year in soybeans and thought it did a good job.

NHDon is right....."don't run it too long that way"! I would think it to a rotor out of balance or it may bent. Could be a couple other things so don't worry if you find it not to the rotors just come back and tell us what you have found. If it is a rotor problem and you do the work yourself....make sure you have plenty of help removing and installing the rotor! It is pretty easy to check the rotor balance and if needed I would be glad to send you a picture of what is needed to do so. IF you find it is a rotor out of balance and you pull it out, climb up in that rotor cage with a good light and look for torn up grates and such. Something may have gone through the machine to upset the balance. Also, if the rotor has been run for sometime out of balance, check in the very back of the the rotor cage, the nuts that are welded to the back plate which hold the rotor gear boxes on to the opposite side of the back plate. Sometimes the vibration will crack the weld that holds the nuts and thus allow the gear box to become loose. On the beans out the back, I took it that you meant you weren't blowing them out....rightIJ Walking them over the screens is the way I understood it.....so my advise would be to up the fan's rpms to get the trash off the screen and maybe open the screen up some. Unless test weight is very low, it is hard to run too much air in average to high yielding crops with a TR...or atleast that has been our experince. I'm sure I'll get flamed for that remarkIJ Good luck, JD

The first thing to try is changing the rotor belt. If the vibration is still there then it could be that the rotors are out of balance. When you get the rotors out if that what it is make sure to change the bushings in the gearbox sprocket.

Thanks for the comments, this is going to be a summer Job.

That frustration is common with almost all "new" to us tools.....or if you have my luck should I sayIJ! I would be willing to bet that once you get rid of the vibration she will smooth out and become easier to maintain. I went through the same thing one year with a TR-85, we ran a root through on the right side and it bent the rotor plus messing up the concaves. Had and extra concave and module but didn't have a rotor on hand so we just kept on running and man was that a mistake. Had more trouble which resulted in downtime than if we had of ordered a rotor and sat still till we got it and installed. Good luck, JD
