Loader Third Function Aux Hydraulics Kit install for B2650

Porchfan · Sep 30, 2014

After having my new B2650 a little more than a week, I realized I should have ordered the 3rd function Aux Hydraulics kit for it when I bought it. Everything attachments sells a kit. 3rd function auxilliary hydraulic kits for all brands of tractors and loaders! purchase online, free shipping within 1,000 miles!!. I was wondering how difficult the install would be and if anyone has done it specifically for the B2650? The loader control stick is next to the seat and not up on the loader. It looks a little tight in there. Just not sure I want to drag it back to the dealer and pay the man. Below are a few pics of the lines and the loader control stick

Not sure now to measure the difficulty of the install. But maybe this video will help you. https://www.youtube.com/watch?v=2pYUAYu18XQ

Thanks. I saw that video earlier. The loader control stick in that video is up on the loader and not near the seat like on my B2650. I'll probably have the dealer do it. They wanted $850 at the time I bought the tractor. Kits by themselves are near that. My guess is the dealer will want more that $850 now.

Go thru sales and not to parts and service.

I added a Landpride 3rd function kit to my BX25 and it did not require touching the loader control. Conceptually, it was "spliced" into the line going from the pump to the FEL control. You would have to do the same, it just depends on how the kit is designed as to where you insert the 3rd function valve. Maybe call EA and ask them about installation options, etc. I see the kit says it's installs in the PB port of your FEL vavle, so you would remove the hose going to that port, connect another hose that now goes to the 3rd function valve (location not stated by EA - probably depends on tractor model), then another hose from the 3rd function valve to wherever the original PB hose connected. You might be able to reuse the OEM hose for the last connection.

I guess what I'm trying to convey is that you won't be adding another hose to the FEL valve, just unhooking one and hooking up another one, so you probably won't need any more room there. Just see how hard it is to turn a wrench in there by the FEL valve.

Edit: Looked at the EA pic's and it looks like they mount the 3rd function to the FEL stanchion so see how much room you have there on your B2650. One thing about a Kubota set up, I would assume, is that it comes with a mounting block for the hoses/ quick connects out on the FEL tube. Looks like the EA version hoses just hang there.

OrangeTractorTalks has a post with some more detail for the same tractor and loader I have. It looks like I need the B7350 kit from Kubota. Time to call the dealer and get a quote for both the kit and how much it will cost or them to install. Afterwards, I'll decide if it's worth doing it myself to save some $$.

The tractor was at the dealer for some work last week so I went ahead had him order the Kit (~$930 kit plus tax and install) for my B2650. I got a call today from him and now he's now telling me he doesn't quite know how to install it. Apparently the electrical instructions are poor. He's being very careful. From what I understand there are only three wires, Battery wire, up wire to valve and down wire to the valve) and chassis ground. There are a couple fuses to install as well. I sent him the instructions to the land pride model. Maybe I should have just done this myself? It doesn't look too hard http://www.landpride.com/ari/attach/lp/public/manuals/380-169m.pdf

So he got it installed yesterday. Here are a few pics. I'll get one of the loader arm with the three buttons it comes with.

Looks just like mine did from the dealer. I took and rotated the 90's off the aluminum valve block towards the center of the tractor. Tucks them up outta the way better and put less stress on the hoses running back the the pump. When I get time I plan to build a guard that covers the bottom and couplers, as I play in the woods a lot.

Porchfan · Jan 24, 2015

I may rotate mine as well. I didn't like how the hoses are tucked in there. Here's a few more pics of the control stick with added buttons for the 3rd function.

Looks like the large white button below the knob is a lock release.

So whadja get that uses the new valve?? :confused3:

Nothing yet. I'm in the market for a grappler and a Skid steer front side hydraulic auger similar to this one. Danuser Model 614 Hydraulic Auger Free shipping within the continental US

The b2650 has about a 9 GPM flow rate at 3000 psi song have to size the auger correctly.

I have a PTO auger and I hate it. I got that sucker stuck pretty much every time used it. Last time it took 2 hours to pull the bit out of the ground.
$500 down the drain in my opinion

I'm gonna wait till spring to go with the skid steer hydro auger.

Probably get a grappler in the next few weeks.
Check CL daily to see if any used ones show up.

tk tom · Jan 25, 2015

Nice. What's the downfall on the auger? Too aggressive?

Porchfan · Jan 25, 2015

99.99% PTO augers cannot go in reverse. There only a few large tractors that will do it. As a result, if you happen to get the bit stuck, it's really hard to get out. On mine, every time I tried to app the boy and pull it up, it just drove deeper.

On a hydraulic auger, with one button, you can reverse the rotation. They are, however much more expensive than a PTO 3pt hitch auger. About 4x to 5x more. I don't care. My PTO auger is doing nothing for me. That was a waste of $500 or so. I also bent the bit trying to get it out.

Chad450r · Jan 25, 2015

I miss spoke I rotated the rear hose in and the front out.

Any idea what grapple you like best? Still researching on my end.

Porchfan,

You might want to double check the B2650's hydraulic flow and pressure. Tractor data has the *combined* flow at 8.7 GPM, but that includes 3.7 for the power steering which is not available for 3rd function. Also, the system hydraulic pressure isn't 3,000 psi, more like 2,500 to 2,700 on our size tractors. I have a B3350 and would consider a hydraulic auger if I thought the tractor had enough oomph. Pretty sure it has the same hydraulic pumps as yours.

Porchfan · Jan 26, 2015

Thanks Bumperm -

Yeah - It might be a stretch using a hydraulic auger. The small ones I've seen will work down to about 5-6 GPM and "up to" 3000psi. If they have the pressure, it'll drill even if the flow is slow. To your point on the B-series tractors and hydro pump - I guess even if you are not turning the steering wheel, you lose the pressure from the main pump? I'm an Electrical Engineer, not a mechanical one. Even so, I'd like to understand how the whole hydraulic system works. Maybe I'll rent a small auger first from our local Bobcat dealer. Better than buying an expensive
auger that wont work

So I haven't even run the remote yet and the friggin thing is leaking. Fresh from the dealer...I just hope it's not the valve. What's the chance the dealer will come by the property and fix it? I'd rather he do that have to drag it 20 miles to him..Here's a video of the leak... https://www.youtube.com/watch?v=mwSUmRKO0Rs

bumperm · Feb 2, 2015

Porchfan,

That looks like an SAE O-ring fitting on the tractor side. Before involving the dealer, try tightening the fittings. put a wrench on the body of the 90* elbow and snug down on the larger nut (this is the O-ring side, and typically will still seal if it's just a little loose) you only have to tighten it snug, and so the fitting doesn't turn. Next with a wrench still on the elbow, tighten the quick connect where it goes into the elbow. Test again.

The above should most likely fix it, but if it still leaks, with tractor shut down and hydraulic pressure released (move any control levers involved with leaky fitting), take fitting apart. Check to make sure O-ring is not nicked. Put pipe thread dope sparingly on any NPT threads (not on SAE O-ring though, or on jic "flare type" fittings though).

Porchfan · Feb 2, 2015

Thanks bumperm. I will try it out tonight after work.

To release the pressure I also think I need to select the valve by pressing the push and pull buttons, after the tractor is off.
I suspect I can do that by turning the key to on position (not start) and clicking the buttons.

Since the lines up to the loader cross member are capped at the moment, if there is pressure on that side, I suspect it cannot push through the valve since it's controlled electronically.
If there wasn't pressure in the lines, it probably wouldn't have leaked when it was off.
