Third function kit

[hyndsight]

I’m looking at adding a hydraulic chute rotator to a 3pt snowblower on my JD 4210. Does anyone know of an aftermarket (manual) third function kit that is comparable to oem at maybe a better price point?
And am I correct in thinking that there’s no good way to tap into the power beyond ports for the backhoe to serve this purpose?

Does the tractor have rear remotes and if so how many? Are you using any rear remotes for other functions now? If so an electric/hydraulic diverter valve would allow two functions from one remote.

I can't answer regarding the backhoe question.

Need to confirm what tractor we are talking about?

No rear remotes. My preference is for a manual control, no electric/hydraulic.

With open center hydraulics you can theoretically string as many power beyond ports in series as you want, letting the power beyond port from one control valve feed the input to the next one. Each one eats up a little more power and moves a little slower. But that might not matter for a rotator.

An easier way to do what yo want to put a manual or electric diverter valve in the line from the existing PB port to the backhoe. Then actuate the diverter valve to select either the backhoe or the rotator.

Assuming he has an FEL....

He could also use a diverter in the curl function of his FEL. Divert to the rotator when needed. Just going to require longer hoses since he doesn't have rear remotes.

Not knowing how his backhoe is plumbed, I assume it has one rather large coupler/hose? If he diverts that high volume circuit to his rotator it may be lightning fast.

I'm afraid the cost of diverting the hoe circuit may be more expensive than diverting the FEL circuit?? Thoughts being he'll have to buy the fittings to tap the hoe line. He'll have to buy a control valve?

The gain of diverting an FEL circuit is he'll be able to always use it. Whereas, diverting the hoe circuit will only serve the rotator.

Don't get confused and assume we are talking about a complicated electric motor/hydraulic pump setup. We are simply talking about an electric operated hydraulic valve. Push the button and the function diverts to the rotator. Release the button and the function reverts back to it's original purpose. Such as the curl function on the FEL.

Summit makes a generic true 3rd function kit that has a quality loader knob with switches. You'll need to adapt the brackets and buy hoses. It's around $500 depending on options.

You already have a 3rd valve on the valve block that runs the loader, you just don't have the lever/hardlines/hardware to use it. The kit's where about $250 or so but they are hard to find now.

Also read this thread, pretty much the same setup you have:

Completed the hard part of homemade 3rd scv remotes install

I forgot who asked me to post this install, but maybe someone can benefit from my home brew engineering on the JD 4310. JD has overpriced the kit IMHO, at $380, I decided to build my own. Fabricated the lever out of 1/2" round stock, used a piece of tig wire for mock-up, threaded the end for...

Thanks for all the responses. I do have a fel, but using those controls are out as I use that to move snow as much as the blower. I’m familiar with the electric valves, just prefer ol fasioned manual spool valves. To much electrickery on tractors nowadays…
Diverting the pb circuit is an idea, but I think I’d need a diverter valve, control valve, (open center 3 position spool?) and related hoses etc. Might be the same $$ as a third kit…
KennyD, that looks interesting if I had more time to mess with it, but I prefer a plug and play option for now. The JD kit you linked I think is the same one my dealer quoted at $480. I’ll probably end up that route out of simplicity, I just hoped someone else was making a comparable kit for a more reasonable price.

Ovrszd, I think I misunderstood your post about the fel curl circuit. You’re saying divert before the control so that when diverted the curl function on the joystick would run the rotator?

Yes. That's how many 3rd function kits work. You still use the FEL control lever. But now one function of the lever does two tasks. Push the button on the lever and movement causes your rotator to function. Release the button on the lever and movement causes the bucket to curl. If you locate the diverter at the front of the FEL this additional function could be used for a Grapple for example.

KennyD, I did a little digging today and confirmed your info, there’s an unused spool on the fel valve block, just need the valve handle and lines run to the rear. $380 at the local jd store. Seems way overpriced, but unless I get ambitious and fab this stuff, it’s probably the route I’ll take.
Just picked up the 64” frontier blower today. Pretty impressive compared to my 25 year old Woods…

$380 for an OEM 3rd SCV kit on a ~20 year old tractor is good deal IMHO.

The oem setup seems like your best option and wasnt aware deere had the spool already there....they just left out the handle and hoses.

Refrain from using the backhoe hoses for anything other than the backhoe. Its is indeed a power beyond feed TO the backhoe...But its not a true return line. Rather than return line is ALSO a power beyond as it continues on to feed the 3PH. So adding a valve on those two hoses, to do so properly would require a PB capable valve as well as a third hose added for a tank return.

They omit this on a backhoe loop....since you cannot use the 3PH and backhoe at the same time so there is little to no risk of blowing a valve.

However....those two hoses to control any other valve that isnt a PB valve with 3-hoses going to it....AND using the 3PH while it is plumbed is a recipe for disaster.

IF you want to add a set of rear remotes to your tractor....the PB loop gets you TWO of the THREE hoses you need. All you would need is a PB capable valve...add the tank line....and your couplers. Probably have the same amount of money in that as the 3rd function off the loader. So you have to decide whether having rear remotes or a 3rd function is more important. Usually the remotes are for anything in the rear....like your blower chute, or a hydraulic toplink, or an angle cylinder rear blade. The 3rd function is for stuff up front like a grapple, or 4n1 bucket, etc. But thats not saying with long hoses you cannot rotate the cute off the 3rd
