For one thing you can't work on them. Picker was working great, about 3 row it locked up. PTO will not even turn. I haved looked everwhere and can not see what is holding it up. Please if anyone has idea I could us the help.
OK, PTO shaft should still turn if the picker is jammed somewhere that is not protected by a slip clutch, because there is a shear bolt in front of the main gearbox. First thing is to take the shear bolt out if it is still intact and see if the PTO shaft itself has a problem. I've never seen it happen, but a carrier bearing could have locked up. After the PTO is eliminated as the problem, then disconnect the gearbox shafts and see if the gearbox turns. I can't think of anything else that would bring the whole picker to a dead stop, since there are slip clutches all over it.
I had a gathering chain come off and get stuck between the snapping rolls on my No.7. Between the very old slip clutch being a little rusty and using a low horse power tractor, it brought the whole works to a stop and killed the tractor. Probably not as likely in your case but I thought I had a big problem at first.
Oh, it's not such a bad machine to work on. You probably checked it, but did something happen to the PTO on your tractor? While you are following Tim's suggestion, open all the gearboxes and see if any teeth broke off and jammed up the gears. Like Tim said, there are slip clutches all over the thing, and most of the systems will make quite a chatter out of those slip clutches if something binds them. However, I had a little trouble one time with the long chain under the shield on the back of the husking unit, and it bogged the whole mess. The shear bolt should have broke, but an enterprising former owner had installed a grade 8 bolt. Pop was on the tractor and stopped it before damage, but lesson learned. The cornsaver, the auger above the husking bed, and the unloading elevator can hide bindups, especially if an ear of corn jams into just the right spot. Check on the underside of both elevators (pickup and unload) to see if a paddle broke and is binding up the mess. Both have slip clutches, but if the slip clutch doesn't "slip", a broken paddle will stop everything. Just a few ideas--please let us know when you find the problem. Welcome to the party.
