we use a 36foot honey bee with bat reals we had to put it right on the grownd but it piched up the lentels good we used to have a flex header and after one year got ride of it and like this mutch better
The 900 series came out with the 9000 series combine. The new combine had a longer feeder house so the mounting angle is different. I have a 912 and a 212 platform with pickup platforms. There is not a big difference but when using a straight cutting head, the cutting angle may need to be looked at closer and adjusted.
