potentiometer?

Did I spell that right? This is on a 1020 flex head. What does it do?

Sensor for auto header height?

RODGEinIL · Jan 28, 2017

Bob's got it.

$130.00 the last time I bought one. It tells the combine what the height of the head is.

On my 1020 head it's mounted up on the back, left side of the header, next to the feeder house. There's a cable which comes up from the mechanism under the header to a lever on the "pot" so that mechanical motion is turned into an electrical signal. A pigtail from the "pot" is plugged into a receptacle on the combine.

Yes, I believe you spelled it correctly.

I don't grow beans. I used the HHC function for the first time this year on drought shortened oats. It worked great, once I got the bugs worked out. I made sure the mechanism and cable were free before heading to the field. But the system worked backwards! I flipped the "pot" over, and all was well. Except that, the header operator manual has a nice diagram of how everything is oriented, and the pot didn't agree. Later, working on the combine, I found wires switched where they had been repaired along the feeder house.

Drought shortened oats? Now there is a theme for 2016! I had 4-5' corn, 12" beans where they got tall...some a lot less. If I never see another year like that it will be way too soon! I did have some nice stands of crab grass, velvet leaf (now there is a fun one to kill!), lambs quarter, ragweed, foxtail...

Appreciate the info! I supected it had to do with HHC. The IH 1020 header I was looking at turned out to be a lot further away than I suspected, so have to let it pass. I want to replace my 820 head. I repaired the wobble box so the next guy who owns it can start clean but I don't want to convert it to work with the 1660. Seems easier to get a newer head. Thanks again!

there is an update to hhc potentiometer to change it from the cable to a rod. well worth the upgrade. there is a also a harness adapter that has a resistor in it to help with "boucning"
of the head. mine use to bounce like a bucking bronco till I did
these up grades.
