Rear Remotes - Planning stages, need advice

[number9L]

I have a Kubota L3800 with FEL. I am wanting to add a Top-n-Tilt setup but want to take my time and plan this out and try and get it "right" (not have regrets) the first time.

There isn't a lot of room on the L3800 to mount the valves in a clean way and I'd really like to use a loader type valve / joystick with Float for running the TnT. I'd like to have the Float on the top link to allow Rotary Cutter, Finish Mower and Box Blade follow the ground. I want to add a Power Beyond valve/remote as well while I am at it, but am fine with a single lever for that function or using a diverter valve may be even better. I want as clean an install as I can work out.

These two valves look like they might fit well down in between the seat and RH fender and work well for what I have in mind. I know I'll have to do some fab work to get them mounted and creative hose routing, but that's fine as I am not in a bug hurry to throw them on in the next week. I want to take my time and do it well and I suspect hose routing will be the most challenging part of this process.

Surplus Center - 2 SPOOL COMPACT 10 GPM JOYSTICK CONTROL VALVE

Surplus Center - 2 SPOOL 14 GPM PRINCE LVR JOYSTICK LOADER VALVE
This one has a 14GPM rate, would that work ok with my tractor's 6.3GPM pump?

I am wondering if I should go ahead while I am doing all this and add a 3rd function to the FEL as I can see that I may want a grapple down the road. I'd want to do a diverter valve for this one so I can just use the FEL joystick.

I've read threads about others using diverter valves where the button to switch the valve is momentary. Is there valves that allow the use of a toggle switch? That seems like it would be more intuitive, just flip the switch and work the stick as needed, then flip it back as opposed to holding the momentary button in the whole time. Maybe not, I really don't know.

I'm just trying to think ahead at all the possibilities so I don't wish I'd done something different once I get it installed and using it.

Either of those valves will work. Both have PB

You should however match the valve GPM with the pump flow.

Using a diverter/selector valve, you can flip a spst switch and lock the valve in a certain position.

Surplus Center - 12 VDC 13.2 GPM SAE 8 DOUBLE SELECTOR VALVE.

Here is a third function valve you could wire up with a dpdt. = double pole double throw. The ports on the subplate are capable of high pressure.

Surplus Center - 12 VDC 10 GPM OC DA SOLENOID VALVE

Surplus Center - 1 STATION DO3 SUBPLATE OPEN CENTER

You could also put both momentary and spst the same switch handle.

Spst = single pole single throw.

You could also plug your grapple into the remotes, and use the joystick to control the grapple.

So would you recommend going with the first loader valve I linked to then since it's a 10GPM valve over the 14GPM valve?

Thing I liked about the 14GPM valve is that all the ports come out the bottom and it doesn't have regen. But if it's higher flow rate would hurt fluid flow or attachment performance I would rather not go that route.

With a larger valve, you are at full flow at about 1/3 lever movement.

With a matched valved, you have good feathering ability.

Here is a joystick valve from Baileys you might consider.

Two Spool Loader Valves LVT Series | Type 4-way, 3-pos. LVT VALVE 2 SPL 220-131

I have seen some nice valve setups on the fender.

Ahh, ok got it. I want the feathering to be as good as it can so I'll stick with the first valve I posted. It's a little smaller than the other one anyway.

I see the valve has SAE 8 fittings and the quick disconnects and cylinders have 3/8" NTP. I'll have to have lines made up to the lengths I need, so should I stick with 3/8" NTP fittings on the lines or go with a different (better?) type fitting? I'm gonna have to buy adapters and 45 or 90 elbows anyway. Also, are these fittings with swivel on them fine to use? Surplus Center - SAE 8M x 3/8 NPTF SWIVEL

I am going to go ahead and get the TnT cylinders and loader valve and do some mock-up to determine the best routes to run the lines and just how long of lines and what fittings I'll need first. I want the line runs to be as clean and just right as I can get them without it looking like a bowl of spaghetti exploded on my tractor.

So I am exploring other valves as I want to be able to float both the top link and side link. Is there any scenario where one would want to float them both at the same time? I can't really think of any right off...

I am looking into this valve http://www.surpluscenter.com/item.asp?UID=2008032012213814&item=9SV-4-Y&catname=hydraulic in either the 3 spool or 4 spool version, and like the fact that it has a joystick option to control 2 valves. I really want to get the valve mounted down between the seat and fender and have the lever sticking up where my hand would be operating the 3pt lever. Just seems like it would be more natural than going from the 3pt lever back to up on the fender or ROPS and back.

Sure you can use a custom valve to fit you applications.

It is rather pricey, but if it what you want then go for it.

Here is a good question,

Can you add joystick levers to two adjacent spools on a stacked valve, and have the T-N-T cyl go into float together.

 

[number9L]

I wouldn't think so, that's why I was wondering if there are any situations where you'd want to float them both at the same time.
