Utilizing Rear SCV's For The First Time

[farmlegend]

Please forgive my rank ignorance. Before I bought my farm, you could fit every tool I ever owned into a lady’s shoe box and still have room for a sandwich in there. I have since expanded my tool collection and mechanical knowledge substantially, but I still have some gaping holes.

Back when I purchased my Deere 990 tractor twenty years ago, I was advised to have the dealer install rear remote Selective Control Valves because it was far better to have it as part of my negotiated deal than it was for me to have to install them at a later date.

There are four of these things mounted at the back of my tractor, and I have never used them. My hydraulic system has functioned from day one for operating my front end loader, and, I suppose, the rock shaft.

I’m now in a position where I have acquired an implement (Land Pride 606NT drill, sitting at the dealer, I haven’t taken delivery yet) which requires attachment to these remotes so that the implement may be raised and lowered.

I’ve been told there must be some sort of “switch” on my hydraulic lines which can be utilized so that my rear remotes can become engaged so that I can raise and lower a rear implement – using, I presume, either the same joystick I utilize for operating my FEL or the rock shaft lever which raises/lowers the lift arms, I honestly don’t know.

I have a hard time conceptualizing a lot of this - assuming I were to switch the hydraulics to direct the fluid flow to the rear remotes, would that make my FEL simultaneously inoperative? In any case, I’ve followed the hydraulic hoses and cannot seem to find a “switch” which could re-direct flow to those rear remotes.

Can anyone shed some light on this subject so that when this implement arrives, I can hook it up to raise and lower it so that I can not only operate it some day soon, but also, and more immediately, back it into my barn on the delivery date?

Thanks in advance for educating me on this.

Shoot us a couple pics! Someone here knows.

Will do asap, which right now means Saturday.

The scv's on my two deere tractors were different. Current ones insert and lock, last ones had a lever to pull straight back, insert fitting and then move lever back.

If it's a new tractor, is the switch not electronic with buttons inside the cab?

I would check the manual. It might point you right to where it is.

This is a 2006 tractor. Open cab.

Nothing in the manual, the standard tractor had no SCV's, dealer added them.

You say 4. I’m guessing you mean 4 connections, meaning 2 valves. You should have 2 little levers side by side, typically on the right side of the seat. I would be surprised if what they installed is operated with any of your loader controls.

Yes, four connections, which I assume is two valves. As I recall, I asked the dealer to install "a pair of rear remotes". Will look as you advised. I'd been looking down below.

If it’s a pull type drill it will lift and lower with the same levers used to lift and lower the mower in your picture. Edit….thats if you mower raises with hydraulics.

If it’s 3 point there are levers on the right side by the seat. One lever controls travel the other lift and lower

Give us a pic of The levers on the tractor to the right of the seat.

It’s a pull behind drill, not a three point.

The mower raises and lowers through the lift arms, controlled by the rock shaft. I would imagine the hoses/couplers from the drill would attach to the SCV outlets.

From there, I’ve got to believe there’s some sort of switch somewhere that I need to engage. I can imagine, since I’ve never used it, that it might be seized up and I may have to shoot some penetrating oil on it and be careful not to break anything.

Will do when I get out there.

SCVs are usually operated with a bi-directional lever, not a switch. Pull back and the hydraulic cylinder extends. Push forward and the cylinder shortens. The lever returns to the center position when you let go.

While we are on the subject - I have the type with no manual collar on the rear SVC joints. Push in and they automatically lock. But getting them out can be a royal pain in the rear. You supposedly push in and pull. There has been once or twice i thought I was going to have to call the mechanic truck. Yes, I relax all attachments to take the pressure off the lines and still have had a really difficult time. Any sure fire pointers for disconnecting?

Deere does a great job putting their manuals online. That's for SN 1-59,000. There is a different manual for 59,000+

Don’t know if yours are the same as mine, but the rear remotes on my Kubota also have no collar. I simply pull hard and they come out. They’re designed to pull out in case your implement is disconnected and you pull forward with the hoses still attached. I can also put a 7/8” wrench on the flat side of the front of the remote and pry it forward. This essentially does the same thing as simply yanking backward.

I’ve invented cuss words getting the hydraulics off a skid steer. What I’ve seen, and do now, is essentially pump the collar a few times that supposedly releases pressure before trying it on pop it off
