Add a rear remote to a Kubota L4310

thendrix · May 23, 2015

I need info on adding a rear remote hydraulic to a Kubota L4310 with a loader. Any info on parts, price, complexity, etc would be greatly appreciated.

Does your tractor have a loader and hyd block?

If so, then remove the PB hose on the hyd block and connect the PB line to the new valve, and then connect the PB from the remote valve back to the port on the hyd block.

The valves should now be n series for a complete flow path.

All tank lines go to tank.

Price will be determined by the valve you purchase as to the number of spools, etc.

If you only need a two spool valve, we can guide you to the right place.

The valve should have a PB port with a PB adapter.

If you already have a loader, then click on the link in my signature below. Your tractor should be EXACTLY the same.

Thanks y'all. I'll have a closer look and report back

You could also add a power beyond remote to the rear of the tractor and mount a solenoid spool valve for more flexibility. I have that setup on my L-series and love it.

Check the dealer and see what the price is for OEM rear remotes. They are nice and a clean set, they pull the power from the back at the rock shaft control.

They are very pricey but nice clean set up.

What do you mean by very pricey? What kind of numbers?

countrybumpkin · May 25, 2015

Last time I checked for my L3410 it was right at 1000 for the first one and 700 each for the 2nd and 3rd.

Just go to Surplus and purchase a 2 or 3 spool valve with the options you want for your new projects, like float, detent, maybe a motor spool , etc.

You will come out money ahead if you can turn a wrench.

thendrix · May 26, 2015

Turning a wrench isn't a problem. What would I need besides a supply and a return to operate a the rear door on a baler and maybe a hydraulic tie circuit? I'm also seriously considering a hydraulic top link

countrybumpkin · May 26, 2015

That would require a three spool to operate all that, one spool for each function. You can buy a 3 spool valve and get the power beyond plug for it, hook up should be pretty straight forward buy using the power beyond circuit.

thendrix · May 26, 2015

Ok. I assume I can t off the supply for the 3pt and that should take care of the return to the tank?

countrybumpkin · May 26, 2015

No , you run the supply ( power beyond) through the new valve, then you can Tee the tank return into your existing tank return line from your loader.

J_J · May 26, 2015

If you have some remotes valves now, just disconnect the PB hose from the 3pt and feed the new valve and then run the new valve with PB adapter to the 3pt input.

Everything will now be in series.

Al tank lines go to tank.

Another question. When running a baler with hydraulic tie, that should only require 2 remotes as the top link wouldn't be used with a baler. It would be used with a disc mower and also an outlet for the raising and lowering but again that's 2 remotes. Could I use a 2 spool rather than 3?

countrybumpkin · May 26, 2015

Yes you could unhook the top link and plug in one of the baler circuits in its place.

J_J · May 26, 2015

Yes, you could use a two spool valve.

The third spool is for whatever.

thendrix · May 26, 2015

Ok. Also would I be correct in assuming a hydraulic circuit in series works the same as an electrical circuit in series? Meaning if I have 3000 psi and I am using 2 remotes that means I have 1500 psi per remote? Does a change in direction of flow (a T in the line) effect this?

J_J · May 26, 2015

No.

Your pump may be rated to 3000 psi, so any hyd component can try and develop the pressure and therefore power.

You can work two cyl at the same time and they both can develop up to the 3000 psi rated pressure, depending on the relief valve setting.

All the valves in an open center hyd system are in series, so all valves will see the pump flow.

The first valve can take all the flow leaving none for the other valves.

If you only use half of the flow, then another valve can use the remaining flow, and still develop the 3000 psi.
