Jeffersonville, OH | My first question is what combine you have it on?
Next thing we see push is guys putting bolts through from top to bottom, and having threads sticking down, instead of carriage bolts with the head down. Some bolts do need to go down, and they need to be the right length so they don't catch.
Next, you can adjust the "pitch" of the guards by adjusting the tilt arms at the rear of the header, operators manual should go through that, if you don't have one, I should be able to post it. Maybe they are pitched down too far, depending on what combine you have. Tires and combine setup can all change that.
You header hunts all the time because something is wrong. If it's ALWAYS hunting, you don't have something right. If it hunts occasionally, OK, but if it's up and down all the way across the field you have an issue. Normal issue is the sensors don't have enough range to keep them from hunting. Another could be the cutterbar sticking, and not flexing and floating through the full range of motion. Header raise and lower speed makes a HUGE difference in this too, once everything is correct on the grain header.
The accumulator makes the system think the volume is bigger than it is...ie, lets us adjust the hydraulics faster for some situations, but then by opening the accumulator we can slow the raise and lower speeds down for when we need a finer control....or I'm sure the guys out west use them for some floatation on gauge wheels, but I don't know, never needed it for that. In flex header country we close the accumulator, then adjust header raise and lower speeds to 8 seconds minimum for both raise and lower, then open the accumulator a small amount, maybe a 1/4 of it's travel to catch any bounce we may have in our header control. Then, when we go to corn, if we want it to raise faster, we can close the accumulator and not have to readjust header speeds.
Headsight makes a kit to add PWM speed control to most AGCO machines and it is a game changer for us helping customers tune in their header control...BUT, if the header isn't working right, you're wasting your time.
