I have 2 ports on left side that are capped off (jic) what are them for?
Like exactly where? Maybe for a 4-1 bucket or a grapple?
Back by the boom arm
Looks like test ports from the size.
Yes, that would be my guess.
I look through the manual and can't find them to know for sure
You may have to follow the lines to figure it out. I don't recall the old 863's with those in that location.
Maybe plumbing for tree spade stabilizers. Edit: You said left side only? Disregard my comment.
I would agree. Looks like ports for rear auxiliaries but the piping for the couplers were removed. Is there any on the other side?
Actually, with the holes in the side plate, I would assume it’s for rear auxiliary hydraulics. Awful small looking though, maybe #6 JIC.
