That's easy to determine (visually), both the male & fm flat face "face's" of the coupler are flat. What might be a little harder to ffigure out is what type it is if it's not a FFC. Take a number off of the coupler on the tractor and see what you can find on the google machine. I used this to find the couplers on the factory hoses for my f.e.l. that Kubota uses. http://pressurecomponents.com/pdfs/crossreference.pdf
By the way, :welcome:
And FWIW, I've never seen FF copulers on a tractors (factory) rear remotes, only sometimes on the loader mounted 3rd function (as they call it) to work with skid steer type attachments that just about universally use FFC's. They make it very easy to clean the coupler prior to hook up and just a tiny bit of dirt/dust entering your hyd. sys. can be very harmfull. They are also at least 2X the cost of the "ag" type one's.
Are flat faced (almost looks like a point) and Ag (round ball) interchangeable or do both sides have to be the same? Reason I ask is the backhoe I bought but haven't hooked up yet (will soon) has I guess what you guys are calling flat faced female couplers and my LS has the round Ag type? Just wondering if I have to switch the backhoe fitting (backhoe fitting looks like a ISO 7241-1 Series A in that chart posted earlier) ... this will be the first hydraulic implement that I have 'added'.
