Hydraulic implement on Deere 1050

Hi everyone, new to the forum, and new to hydraulics.

I'd like to run an implement (a gregoire DX-20 leafer) off of a Deere 1050. The pump output etc is all well within spec (for gpm+psi), but unfortunately the 1050 has no additional ports / quick disconnects available.

I guess the hydraulics are just plumbed to the steering and the lift for the 3-pt hitch and there's no additional "selective control valve" ports available?

Is my only option to find the (expensive and not available anywhere I've looked) Deere SCV for this tractor, or is there another way to tap into the hydraulics? The implement itself has all of its own fancy electronic valves, so I think it just needs one "input" and one "return".

You want a "power beyond block", I believe there's such a thing available for the 1050, but it's not shown in the tractor parts catalog (that I can see). IF available it's probably shown in the parts catalog for the loader to fit that tractor (of which I don't know the number).

Some versions MAY have plugs that can be removed to set up "power beyond" with no block needed.
If you could find someone at a dealership that has been there since the era when those tractors were new, they could probably help you.

Also, it would be good to have the serial number when researching this, as there are two versions of this tractor, with quite a few changes, up to serial # 11,000, and 11,001 and above.

Also, post this lower down on the page on the DEERE-specific Forum.

Every tractor with hyd system will have a
port to check pressure. Probably have to
tie lift arms so won't go to top. Then
move 3 point lever to top and system
should pump full pressure to this port.
Then run return line into hyd fill.
Should be a port sonewhere around 3 point
to do this. Best would be to go to John
Deere dealer and ask. And look at their
computer picture where they would jump
into system for their scv. Northern has
valves reasonable. Hope this helps.

I have an 850 and looked into adding hydraulics years ago. The factory kit has not been available for years, and when they were available, I understand that they were very expensive. I exchanged emails with someone on this board who was attempting to rig their own setup, tapping into the hydraulic junction block where the JD selective valve would go, and then using off the shelf parts for the rest of the system. At that time, they referred me to a company in SC that was offering the modified junction blocks for $175, but they went out of business soon afterwards. I reviewed the hydraulic schematics in the service manual, and it looked to be pretty straight-forward to attempt it. I would think that a good hydraulics shop could rig the setup pretty easily. A good machine shop can probably modify the junction block pretty easily, just drill and tap two holes in the proper locations.
I still have the 850, but I ended up with a bigger tractor with hydraulics. I see the SCV assemblies on ebay occasionally, but they want a fortune for them.
Good luck with your search, and if you do rig up a system, please post photos for us.

I have a Yanmar 330 which is about the same tractor as the JD 950/1050 that a vineyard owned,they added a remote.Just tapped a valve into the pressure line going to the rear hydraulics,then out the new value onto the back.Mounted the valve on the right fender it all works great and the 3pt works fine too

Maybe some like this? Hydraulic Multiplier Kit, SCV Splitter/Diverter Valve Including Couplers and Switch Box Contro

I have the info to tap into a model 650 and 750 but I'm pretty sure they are different ? or maybe similar ? Those you have 2 ports on the rockshaft control valve. You install a set screw down into one of them and then hook your hoses up. 1 goes out to a control valve with a power beyond built in. The power beyond goes back to feed the rockshaft.

Open Center ? Plumb the new loader valves in series in the high pressure line from the pump.
Has to be a functional relief valve in the correct position or the system will fail due to over pressure .

Well, I've learned a bit in the past few weeks and have come up with the following plan. I think since this tractor has power steering, and since I'm willing to give that up, it'll be remarkably easy to hook this implement up.

The implement itself needs the following: A hydraulic pressure line, a hydraulic return, and a very unrestricted "case drain" line used by the hydraulic motors on the implement. The previous owner of the implement simply plumbed this "case drain" to the oil fill cap on his reservoir.

Since the implement is "open center", (it always has hydraulic fluid flowing even when the individual functions are off) and since the implement has it's own electronic switches for the hydraulic functions, it would appear I do not need to add the (difficult to source) SCV to my Deere 1050.

The tractor has power steering which I will disable. The power steering had a pressure and a return delivered to the steering valve by a "Flow Divider Block".

I will simply disconnect the power steering hoses from this flow divider block, thread in quick-disconnect fittings to the pressure + return of this flow divider block (where the power steering was previously connected) and attach my implement there.

I'll also conjure up another return for the "case drain" to dump directly into the reservoir via the fill cap.

When the implement is disconnected from the tractor, I'll put a loopback hose in it's place to dump the pressure oil thats coming out of the flow divider block straight back into it's return.

Curious if anyone sees any problems with this plan!

Thanks everyone for all the insights.

Nevermind. The power steering is only provided a limited (1.75GPM) flow of hydraulic fluid. Back to the drawing board.

The trick here is figuring out where to splice into the system while being sure to keep the pressure bypass, part of the rockshaft assy, in the loop.
