Couple ?'s as I watched some video's on these this morning after your post
Does it have a thumb..?........Apparently theres a round hole on front Right of cab/house that switchs the hydro flow to the thumb pedal....why its there I don't fully understand .. Goes from just 1 way flow to 2 way...
Secondly....... Can you switch this to Cat controls or did Mother Dear..fix it the deere way...?
I've seen it a toss-up for switching from ISO to SAE controls. Some are a push button, some are a lever. On anything 20 years old or less it's usually a simple 5 second ordeal to swap. Gone are the days of swapping hoses.
