Greetings everyone.

I started a project to add Power Beyond (PB) to my 2520. I reviewed the prior threads on PB and took their lead for the plumbing details (thanks). I added a little of my own twist - a dual control valve and a custom bracket. It's not complete at this point, but I hope to complete it soon.


Started with a model of the setup in Google Sketchup
Product Parallel Auto part Cylinder



Exported the geometries to my plasma CNC, and cut the bracket parts.

Checked alignment with the valve - perfect
Fawn



Unfortunately had to cut the vertical piece again to get the right placement on the tractor. I also added a 5/16" threaded hole to the base bracket to relocate the seat belt holder to this bracket.

Welded the bracket parts together. Note the threaded hole for the seat belt holder.

Everything looks good so far. Next I get the bracket powder coated and complete the plumbing to the tractor.

So, how much :gizmo: do you have in it so far?
I'm assuming this is a serious question.

If you're talking about the bracketry, not much. The largest expense will be the powder coating. The steel was free and the cutting/welding cost me electricity/consumables (Oh, and my time).

If you're talking about the PB stuff, $200. I'd say I saved a fair amount of money. :good2:

I just realized that you have two different Deere cutouts there, did you get it upside down the first time? Not criticizing, because I couldn't even dream of being as creative as you are with this! So have you thought about making and selling them? You have a captive audience here.....
Nope, since I didn't have a model of the structures around the position of the SCV (seat and ROPS), I guessed wrong in terms of height and horizontal position. So I re-made the vertical piece.

Depending on the response in this thread I would consider making them for others.

Your install looks great. :thumbup1gif: I have a question though, you said that you needed to get power beyond, are you just going to bungee one of the valves open. Those are not detent valves, so in a sense you still do not have your power beyond.

Just wondering what you plan on doing is all. :unknown:
MtnViewRanch, you're observation is correct! It's not a true Power Beyond. BUT, it could be. What I mean is, this SCV is capable of feeding a hydraulics loop beyond itself. See configuation diagram below where a plug is used to make the valve feed another loop.

While this is true, instead of having to do that, why not have a separate valve to prove the power beyond? No connecting and disconnecting the flow source when you have a valve intended for that purpose. I provide those type of valve systems all the time, just makes for a cleaner system IMO. I now know that you do not even need a power beyond source, just a control valve. This was not clear in the original post.

Again, nice setup. :good2:

MtnViewRanch, maybe I'm not following. Could you elaborate?

I intend to route the output and input lines from the trans-axle to the SCV I show in the first post. No need for other valves the way I see it.

Thanks for your coaching here.

You are correct, for what you are doing, (controlling a hydraulic cylinder) there is no reason to provide anything with a constant flow. Your valve setup will work fine. In your original post, you said a power beyond setup. When I hear that, to me a person requires a source of a constant flow to operate something such as a back hoe, or a log splitter. Something that has it's own control valves that simply need a source and return for fluid. This was not what you needed, you just needed a control valve (SCV) to operate the hydraulic cylinder-s on the implement that you are making.

Ultimately my confusion has been my lack of understanding of what you needed. So I apologize for that.

You should be all set once you make your connections and install the pipe plug down on the tractor end of things. :good2:
Understood. I used the term Power Beyond inappropriately here. Sorry for the confusion.

Yes, I have what I need for tapping into the tractor. When it happens I'll post pics. Stay tuned.

Today I succeeded in finishing the install by completing the plumbing down below. I choose to take a different approach from the others I've seen on GTT. I wanted to avoid buying new o-rings and getting hydraulic fluid all over. So I went in through the seat and selective control linkage. Took about 2 hours.

Thank you for the parts list, I am getting my 2032 next week and this is one of my first projects to add to it. I wonder if your bracket will fit it?
Hookoil, I haven't looked at the 2032. There are two main factors at play. First is the mounting bolt pattern and bolt size. Second is surrounding structures (interference with the bracket and valve) - from what I see on the John Deere parts diagrams there's a good change things are similar/identical.

If you can give me accurate dimensions for the bolt pattern, I can verify this. Regarding potential interferences, perhaps you can take pictures and we'd have an educated guess.

Thinking about doing this so I can add a top and tilt to my 2025r , did u have to remove the valve body from the tractor to get the plug installed as well as the in and out hydro lines ? If so does fluid go all over ?
No and No. I used the technique shown in the pictures to avoid removing the valve body. To me, I'd rather spend the extra time rather than disturb the seals and get oil all over the place.

As you can see in the pictures I removed the seat, and the SCV linkage/lever to get front access to the port where the plug goes. It's a little tedious but worth it to me. You can see from other posts (on this forum) how to install the plug.

Regarding the in/out fittings, I only had an issue with the XLong fitting. It wouldn't rotate all the way around due to the forward/reverse dashpot (called Torsional Damper in parts catalog). It was easy to move out of the way to get the fitting in. You can see in picture IMG_6140.jpg (in the prior post) the dashpot is removed (missing).

Hope this helps,

JDDave
