Hesston 1170 wrapping material around top auger

Agree with what Swman said, been a while since I seen one of them, think you have smaller augers than what is in my Macdon Multicrop, but I run into the same most often when there is taller fescue alone or part of the mix, most often it seems to originate when things are hanging up a bit and moving across slower than they should. Worst offender is the additional top cross auger, like what some call a pea auger on a draper table, have never been able to figure out how that starts, but once it begins, within a few seconds I have seen that top auger wrapped from one end to the other and jammed tight.

Check for burrs and such on you flightings.

Also, curious, do your augers counter revolve or both run the same direction?

Was funny that after commenting on here was back out cutting yesterday on a normally pasture quarter and had nothing but grief with fescue wrapping on my top cross auger, maybe I jinxed myself I dunno. Was a heavy mix of alfalfa, timothy, red and alsike clovers and fescue and it is the fescue that wraps. Now one thing I do know seems to contribute from the past, is when I am cutting in damp conditions, which is a real problem this year in anything but normal clean stands of alfalfa mix hay. This stuff I was cutting was bent over and growing along the ground, all intertwined and oh so wet underneath, even on the high land not that there was water being thrown off the tires, but when you stopped it would be dripping off the lower lugs and those are large turf type, so for me, I blame most of the issues on it being so wet. Even the knife is running into issues in that stuff, and previously had knocked down some normal stands of alfalfa mix at double the speed and virtually no issues. It always happens so fast, hard to say why that fecue can wrap as it does, makes no sense really.
I remember years back I think New Idea used those small augers like you have, and a friend had nothing but grief in some nasty red clover that was wet and rank, and it was in that very field after he arranged it, he and I got to do the first demo of the first Deere discbine that come to Martin's in Edmonton, was his field and my 4020 on it. He ended up getting rid of that machine and went with an early Macdon with the undershot auger table, similar to like what my Speedrower had. My dad at the time had a Case 5000 with a hay table with those small augers, it was similar to how the Macdon Multicrop is set up, but while I never remember him having issues with anything wrapping, I could cut laps around him with my Speedrower.
My cousins have a Deere header for their swather, and I am sure it has those same style as yours small augers and I know they have had grief, so much so they stopped using it and instead of selling their Speedrower, kept it just for hay because of how horrible that header was.
Then with that Multicrop I got, its not quite my Speedrower, but give it its dues where they are deserved, that sucker can cut and put it away under good conditions, but like in what I was cutting yesterday, an undershot auger table IMO would be much better. I also have a very under used 1475 NH with a 16 foot header, just don't hardly every use it anymore, the selfpropelled is so much more handy, but yes it handles the rank crap much better than the Macdon. However, takes a lot less power to run the over shot auger tables than the under like what NH uses...thats why I can push my Macdon as I can but yes at times that little 4 cyl Cummins is right at its limits, but is much less power than required to run that NH hydraswing.
Can't get the Multicrop anymore, added bonus with them was you can drop the crimper and cut grain under most conditions, canbe brutal on ripe stuff, so I have a 960 draper as well, so if I was to go with something newer, def be undershot style. I won't go to a disc simply because of my rocks, I have fixed way to many of the neighbors machines to know what kind of damage and expense that becomes, and I have no real issues with a sickle.

Btw, that Multicrop's two augers, one about 8 inch diameter, other about 10, two to three inch flighting, and they both turn the same direction and only the larger rear one has a stripper. And then I also have the additional cross auger at the top, you need it for tall stuff and grain.

I think it is to do with how wet things are, which is why so many of us are having issues with things like this more this year than most. I was thinking about this last nite, wonder if adjusting the tine timing of your reel would help some, as in either earlier release or later. I know that has an effect on my Multicrop header, I would like to run a more aggressive tine timing, but that has a tendency to carry the material too far rearward and that effects flow and creates even more issues with that top cross auger. I also have the ability to adjust the speed of my augers and reel independently as they are driven hydraulically, which I wouldn't doubt would help you in your situation as well.
