Only thing is to unload at full throttle. Even then it will probably seem slow. Also, check the slats that cover the augers in the grain tank, make sure they're all the way up. A tip: when unloading at full power gently engage the unloader drive. Earlier 1680s had a shear bolt protecting the unloader drive and it will break every time if you just haul off and yank on that lever.

Maybe if the flighting is new check the timing at the top in the divers helmet? There is a certain way it has to go, some machines have a decal up there showing the correct way.

Just as was said above, check the slides in the grain bin. Also, if the cross augers in the bin are very worn, they won't move as much crop.

Re: Case IH 1680

I agree check and make sure the elbow is timed right. Start the auger at lower throttle but then increase to full throttle. Also on our 2166 and 2388 we find that wet grains sometimes does not flow into the unloader very smoothly and unloads slower than normal. also check for loose slipping chains but that usually is pretty noisey hard to miss.

Re: Case IH 1680

When checking the auger timing, the horizontal auger should be one quarter turn behind the upright auger I beleive. If the horizontal auger is two sections, It could also be out of time there. It should be assembled so that the flighting ends line up with each other and it just carries on like one auger.
