I have a year old 9870 and yesterday in the barn yard I lost my feederhouse raise ability. Dealer led me through all of the addresses on the arm rest screen and all the functions on the hydro lever are recognized, feederhouse goes down but not up. This happened last year on the third day of harvest we lost 2 days trying to fix it and finally we accidently found the problem which was, the auger engage button was stuck on and some how that cancelled orwouldn't allow feederhouse to raise. Thats not the case this time. Its not throwing any codes either. Its labor day weekend, won't get any help from dealer till Tues. I was gonna start cutting beans Tues. or Wed. but I don't think the dealer has a clue where to start , we have a $2.15 inverted basis right now on beans so time is money. Starting to think maybe I should go shopping for another brand of combine to go with my 12RN Gerringhoff and my new 40ft MacDon. Would appreciate any help or suggestions.
