1020 cutterbar breaking?
On the next to last day of wheat harvest this summer, we almost totally redid the 1020 head. We put all new guards, new sickle, and a new wobble box, due to problems with breaking the sickle. Prior to that(the first day of wheat harvest),we noticed a break in the cutterbar where it bolts on by the wobble box. We welded the break, at that time.
Since the major repair, we probably only have used the platform on about 300 acres of wheat, and just recently milo.
Just started on some beans yesterday, so the head was set up in the flex position, and I had been cutting for a couple of hours when I headed up to unload, but before I got to the truck, I noticed BIG shakin' going on. When I stopped to look(I was afraid, as I had an idea what had happened), sure enough the cutterbar had broke, right beside where we had welded it earlier this summer.
We re-welded it, and this time put a strap on top of it, to re-enforce it a bit more. Case/IH techs said this is a common problem with the 1020 heads, and more than likely the cutterbar is just suffering from metal fatique and needs replaced. It is a 1997 model, so they may be right.
Do you guys have much trouble with the cutterbar on these 1020 flex heads? If so, is welded and putting an additional metal strap on to, a good way to temporarily fix my problem? I have a good 7 days of harvesting beans and milo left, so guess if I need to dismantle the head and replace the cutterbar, I can probably do so, but would prefer to wait until I am finished. Any ideas, better than mine?
