Here are the revised schematics, with and without a backhoe. I have updated some of the line fonts, made a few changes to (hopefully) make these easier to understand, yada, yada, yada. Please review the "colors/notations/legend" section in the upper right as some of mine are unusual, again in...

Further, to update my first post regarding the steering gear, the system used on the Massey Ferguson GC tractors is used extensively on other tractors and off-road equipment. It is a completely hydraulic system with no mechanical link, i.e., if a hydraulic line in the system breaks, or if there...

I want to add some finishing touches to this thread, before I start a new thread on all the revisions I have done. From my original post: "11 In paragraph 8 I discussed the dividing valve within the control valve, and the power beyond line to the steering valve. I won’t delve into this anymore...

Wow, that's a tough order; I'm not particularly adept at freehand drawings. I can certainly send you photos of the valves either here or by email if that's what you're asking for. And yes, I can work with *.dxf (or *.igs) files.

Thank you and welcome to both the Forum and the "GC Club". I am remiss in posting any of the diagrams for my ongoing updates with remotes (a work still in progress). However, basically you have to break into the "power beyond" line (#6) from the loader valve to the backhoe (assuming you have...

Hi @polarred21, Can you send a sample of what you have in mind? Thx, Dick

I can try; thx.

Massey Ferguson GC 1723EB hydraulics: update on original factory plumbing – updated from post #18 Once again, a new update: - 12/7/24 file had some errors - tried to simplify - made the "no backhoe" version a separate drawing Since you won't be able to read these on the forum, I am attaching...

Massey Ferguson GC 1723EB hydraulics: update on original factory plumbing – updated from post #3 I have a 2022 Massey Ferguson GC1723EB TLB (tractor-loader-backhoe); her nickname is Fergie (named after the red-headed Sarah Ferguson, Dutchess of York). Much of this applies to other Massey...

Funny thing about the backhoe boom float: Massey Ferguson has a service bulletin (23-0081) to add a dual pilot operated check valve on the backhoe boom circuit and reads “The backhoe boom can settle downwards if the operator uses the dipper function, bucket function, swing function or outrigger...

Yes the backhoe boom float is unusual. It is to help leveling the bottom of a ditch, etc. See:

Thanks for the education. As I mentioned above to @5030, I am still a neophyte on hydraulics. Yes, all the stock valves are spring centered, with a detented float for the loader, a non-detented quick dump for the bucket curl, and a detented float for the backhoe boom. The 3-point valve has a...

Thanks for the explanation. I'm still a neophyte on hydraulics. The factory does not supply any rear (or front) disconnects except for what's shown in my diagram for the loader and backhoe. However, I now have four sets in the rear and will chronicle them when I get them working to my...

I'm not sure what you are referring to. If by SCV you mean solenoid control valve, there are none in the Massey Ferguson OEM system. Please explain.

Sorry about that. Trying to cram 10 pounds in a 5-pound sack. The reason that some of the components are spaced out is so they didn't have to change position when I added my rear remotes and other bells and whistles (to come soon). Please let me know if there is anything "wrong with this...

They were, they were just too small, and I've redrawn them. Perhaps they were blurred in the picture which was just a screenshot of my CAD file; I have now inserted a screenshot of the pdf file. You can also open the pdf file and zoom in on it.

More on how Massey Ferguson GC 1723E & 1725M hydraulics are plumbed As stated before, I wanted to learn more about how my 2022 GC 1723EB TLB was plumbed so that I could add various items such as top-n-tilt, etc. I am well along on this journey and will document the modifications and missteps...

How Massey Ferguson GC 1723 & 1725 hydraulics are plumbed - part 2 A lot of this should be applicable to other GC model tractors. Also, as I described in the first post, I am new to all this so please point out any errors. Belated answer to the question @WranglerX asks in the hydraulic...

There is an update to the first three posts now: post #18 12/7/24. How Massey Ferguson GC 1723 & 1725 hydraulics are plumbed - part 1 A lot of this should be applicable to other GC model tractors. Also, as I describe, I am new to all this so please point out any errors. Sorry, very long post...
