Posting some photos I took of my B250 when I first got it and I was asking people what things were. I learned 12 is the tranny fill plug and there is a small bolt on side you take out which will dribble oil when its full enough. Also in this photo you will see a metal tube joined with a rubber hose. This is the tube that gravity feeds the hydraulic pump for my loader. I expect the pump also sucks the fluid. The rubber line below it is the return line from the loader spool valves to the reservoir tank behind seat.

Here is a photo of the rubber line that returns oil to the reservoir tank. Last owner plumbed it in with a T fitting so he could top up reservoir tank. Parts 11 in my owners manual show 1 chain each descends from each of these to lower links of 3 point hitch.

The hydraulic line between caps 2 and 4 is a return line from my loader spool valves. Caps 1, 3, and 4 I was told by "MJ in the UK "They are not hydraulic takeoff points, they are for adjustments of the valve chest. DO NOT undo them while the engine is running." My manual says nothing about them so thank you MJ from the UK.

According "Fritz Maurer" and my operators manual the cap labeled 2 can be removed and a remote coupling added. Thank you Fritz. The remote coupling would be an attaching point that a hydraulic line could be attached to from a farm implement or to a wood splitter. I expect B250 dealerships back in the day sold a remote coupling that mounted to tractor. Cap 2 would be removed and a line was added with a banjo type end fitting. At other end of remote coupling line it had a self sealing end so dirt would not enter until a hydraulic farm implement was connected. My tractor does not have a remote coupling. I was told by "ihplowboy" and read in my manual that you turn the "T" handle (isolating valve) fully out ccw for the 3 point hitch and fully in cw to operate the remote coupling.

I'm now thinking the handle that controls the height of the 3 point hitch arms then controls the remote coupling flow\pressure I expect when the "T" handle is turned cw fully in??

Manual says make sure isolating valve is fully turned in or out.

I may mount a hydraulic winch on rear of my B250 so I'm thinking the remote coupling would be the way to go. I expect I would still have a return line to top of reservoir. I have the spool valves and lines to control direction of winch also.

Here is a photo of the remote coupling from my B250 owners manual:

I expect a shop could make up a line, maybe not with the fitting shown in the diagram yet something that will work. Possibly thread a straight or elbow fitting into valve body and then attach a line to it. Then just cap off line when not in use.



Here's a photo of my tractor when I first got it.
