3rd function for my Kioti NX6010

[AWSubie]

I chose to go with a 3rd function on my NX5010. The pics show the basics of what I did. Of course there are many different ways that it can be done. I couldn't figure out how to rotate the pictures correctly, you'll have to save a screen shot and rotate them for easier viewing.



This pic shows the right aft wheel removed to see the access hole where I mounted the servo valve. There are existing threaded holes in the transmission casting that allow convenient mounting of a bracket to support the subplate and valve. This location is also near the loader valve so that splicing in to the power beyond (Kioti calls it "Carry over") is easy.



Close up of the servo valve. The power beyond line is 1/2 inch and the working port lines are 3/8.



This shows the routing of the working port lines to a bracket that I mounted just below the loader Quick Disconnects.



The Quick Disconnects for my grapple mounted in a simple hose clamp. Nothing fancy.



The clearance between the 3rd function Quick disconnects at the loader arm and the right front wheel in a hard right turn.

Nice looking setup AWSubie. Was this a kit you purchased or did you buy everything yourself? Am I correct that it looks like you used steel lines along your loader or are they rubber the whole way? What did you use for a joystick handle? How much did everything cost you if I could ask?

Can you do all 3 functions at the same time? I operated my loader like N2DFire suggested. If I pulled the joystick full back and then slid it to the right or left I could not curl the bucket unless I feathered the raising of the loader first. I can actually get a little better function out of my 4600 John Deere but not a lot.

I'm thinking a diverter system tied into the lift function may be the way to go. I'm trying to decide whether to buy a premade kit like MIE sells or get the parts myself and install them.

N2DFire, if you're watching, how much did you have into your setup and were the parts readily available?

Thanks guys.

Of Course I'm still watching (especially since the boss is out today LOL).

You might be interested in this very recent thread where-in another fellow was wrestling with that very question. Some good comparison info & pricing there.

Cost is going to vary based on how simple or complex you go & where you shop. I think he said he finished up for about $360, My set-up was probably a little over $700.

I added several "extras" the kit's don't have (Hose protector sleeve on everything for example) or things you can do simpler / cheaper (I made a relay control box, others just used off the shelf auto relays).
I used a much more expensive sub-plate due to the port layout and I also replaced the entire grip knob, this user just bolted a switch to the existing grip.
I bought hoses locally, you can have them made online cheaper just be 100% sure of your measurements before you order.

On that note - Hoses are going to be the single most expensive item in the whole project (and the fittings are the most expensive part of the hose assembly) so keep in mind that a diverter (depending on where you mount the actual valve) will use fewer / shorter hoses than a 3rd function valve.

To answer your other question, yes components are readily available and from several places so sourcing parts shouldn't be an issue.

Either way you go 3rd function or diverter I still think you can assemble your own system cheaper and get as good or better results than pre-made kits.

Like I told the fellow in that other thread - all projects require 2 things: Time & Money. The more of one you have, the less you need of the other. Pre-made kits are more costly as a "convenience fee" for you not having to spend the time to source, fit, and assemble all the parts.

All good stuff, just a couple comments:

When considering "Third-Function" kits, make sure they do not interrupt the Power-beyond circuit in the tractor. This can cause damage to the tractor hydraulic system.
Some "Third Function" kits are just on-off control, not allowing the operator to "feather" the control of the third function.
The "convenience fee" in our custom kits is the labor cost to cut and fabricate the custom brackets, assemble the hoses and fittings, set up the valves, etc. Our shop guys like a pay check just like everyone else.

Hope this helps...

Thanks for the info guys.

One question for you at MIE, can your diverter or selector system be installed in either the curl line or the lift line for the loader? Have you had customers do it in the lift line before and how has that worked out?

Thanks again.

Not MIE but normally yes you can install it in either circuit....just a preference thing.

But you "may" not be able to install it in the curl circuit. Just depends on the valve.

There are 3 types of curl.
1. Standard non-regen valve. Yes you can install a diverter in this type
2. Regen valve that also has standard function. This would have a noticeable second step that you have to push past a detent. Kinda like loader lower vs float. And yes, diverter works in this too.
3. Regen only. No you cannot use a diverter on this. Technically you can, but the grapple will have only about 20-30% clamp force, and likely wont grip anything well enough to pick up.

Dont know what the NX has, perhaps others can chime in on that.

Schoppy: I bought everything myself based upon all the information that is on TractorByNet. I did use Kioti steel lines along the loader arm; because I thought it looked nice but... I don't think I would go this route again due to cost. Kioti wanted $98.81 for two steel tubes and a four-hole clamp plus they charged me $15 for shipping even though I picked them up at the Kioti dealer. I also bought British Standard Pipe Parallel (BSPP) adapters to for the tubes to mate up to 3/8 NPT male hoses. Hoses along the loader arm would have been much less expensive. I used the John Deere joystick handle that you read about on this site. I purchased it from the GreenPartsStore.com for $30.63 (includes shipping). The John Deere handle requires a slight modification of the Kioti joy stick. You must slot (elongate) one of the holes in the joy stick so that the bolt holes in the handle will align (at least that was my solution, easy to do with a dremel). Total cost to me was $806.69; however, I made mistakes in ordering parts costing me about $50. Also I ordered most components from Surplus Center and Discount Hydraulics where the total in shipping charges added up to $99.23, mainly due to my lack of experience with hydraulics and the different industry standards causing me to make several separate orders. Had I been experienced with hydraulics from the get go, I could have done my ordering in two batches of parts and saved greatly on shipping. So realistically, I think you can buy everything you need for a little over $600.

Can I do all 3 functions at the same time? Well...I don't know yet! I just ordered my grapple yesterday and I don't have another implement that uses the 3rd function. I did work with my tractor today and at 2600 engine RPM the loader had no problem raising and curling at the same time and I could make the ends of the 3rd function hoses "dance" by pushing the button (I realize this is not true test for the 3rd function since I did not have the cylinder to fill on the grapple (I bought a single lid grapple). The Kioti main pump supplies 9.6 gpm at 2600 rpm and this seemed more than adequate to operate both functions of the loader simultaneously.

If you like working with electrical, mechanical and hydraulic things I think you will enjoy the project whichever way you decide to go.

Thanks AWSubie, I like doing a lot of that stuff myself just because I can and am pretty picky about my equipment. I will have to see how I go, dedicated or diverter system.

Our kit can be installed in either the boom or bucket curl circuit. I can't remember anyone installing the kit in the boom function, but there isn't any reason why you couldn't. Normally, our customers want to be able to use the boom and 3rd function at the same time.

Hope this helps
