If I understand your post correctly, you want to buy a corn head HH kit. I would ask where you are planning to buy it. Or are you looking for a used kitIJ
No, I have one for sale. The dealer gave it to me when I bought the combine. I never installed it and I do not have the combine anymore. The Kit uses potentiometer, therefore it would have to be a 1998 combine or newer. My combine was a 1994 that was updated to use the new sensors. Peter
