This got sent into dtac but no response yet but I have 2 new 9770 sts combines. Both with 800 metrics, identical. First combine does 18.2mph, 8.6mph and 4.5mph in the 3 gears. Second combine does 28.1mph, 12.7 and 6.5 mph. Can that thing haul a$$ down the road or what?
I guess it isn't supposed to but sure is nice for moving fields. Scared something might break in the long run so will use first gear for combining in field until it gets figured out.

Anyone else have this issue?

i and everyone i know combines in second. but our crops are not what you guys make. say here average year, average cutting speed could be as high as 12-14 klms/hr or 9+ mph. i have cut 10bpa wheat flat out in second gear before. off course heavier crops, irrigated wheat means cutting a whole lot slower.

being faster also makes them 'weaker'. i cut some wheat a few years back in hilly (for us) land and could not cut in second as the combine wouldn't climb the hills with a full grain tank.

First off, does the one actually go faster down the road if you leave at the same time? If not check the settings in the command arm, its probably in metric, I have seen a few show up this way, if you do the math on the speeds you said it was going I think this is the solution, or you have a fantastic Prodrive!

Check the hydro motor (bolted to trans) you will find it to be smaller than it should be. The one that goes faster has a motor for a single tire 9570. The small motor large pump combo is what is causing the higher road speed. Had this same problem.

Make sure your tire size is entered in correctly......that could be the issue. We usually swap off duals for singles, and sometimes they forget to change the tire size. Same thing happened to us this year...I thought we had a super fast machine....nope, lol.

Can someone tell me how to do this on a 60 series sts. Is it radius, or diam?

thx
