87301386E Hydraulic Connector – Single Point Hydraulic Hookup
We made our own Hydraulic hookup kit.
The head needs to be tilted as far forward as you can get it. If not it drag up under the header. We actually had to make some extension brackets for our 2366 without field tracker. With field tracker it is not as big of an issue.
You will have to move the sensor arm to the outer bolt hole and may have to lie to the display and tell it that there are 3 cylinders instead of two if AHHC makes the head to jumpy.
It is heavier than a 1020 and if you have upper bearing plates (pn 100273A2) are worn or not greased you will know it quickly, as it will stop tilting.
Also this is a metric head. You will need a new tool box full of metric bolts, sections, and guards.
Imho. It is as good if not a little better than a 1020. And with everyone around here wanting drapers you might be able to find a good deal on one. Good Luck!
