not to sound stupid!! But I AM!! What do you mean by a rear remote? And how is that different from a "Power Beyond Valve"?? I was told I need a power beyond valve to run my demolition hammer when connected to the back-hoe. I have a 2001 L35 TLB. I have had my hammer for 2 years and cannot get the dealer to order the power beyond valve parts. He says he has no idea on what to order!!!
From what I can figure it is just the outside housing (output side) of my controle block (for the hoe), that diverts the oil diffrently than what is there now.
Unfortunatly I don't need the hammer anymore (hired the work out, couldn't wait)
but I'd still like to either figure it out or sell it

Your remotes are "open center", not closed center.

Not stupid at all...but it sounds like your dealer may be. "Power Beyond" is just a way of plumbing remotes, it's not a "valve". The PB is basically a constant flow of hydraulic oil whenever the tractor is running and is used to power things that have their own valves like backhoes and logspliters.
I am not sure of the requirements for a hammer, or what machine you have...but if you give some specific details and links to what you have (maybe start a new thread?) I am sure we can help.

Okay, educate me. I have a double acting hydraulic cylinder, top link, blade angle, etc. I move the have handle to extend or retract cylinder. Cylinder stays in that position until I move valve handle again. That is why I say closed center, because cylinder holds position. So where does the terminolgy open center come from? Thanks. Philip.

In open center valves, hydraulic fluid flows through the in and out ports when the valve is in neutral. In closed center valves, flow between the in and out ports is blocked when the valve is in neutral. In all cylinder valves, open or closed center, the cylinder ports are blocked when the valve is in the neutral position. In motor valves, the fluid is free to circulate between the work ports when the valve is in neutral, allowing the hydraulic motor to coast.

The term "closed center" refers to a valve that is "closed" when the handle is in the neutral position. Usually any system that uses these has a variable displacement hydraulic pump, such as a swash plate type pump. Otherwise, any flow the pump creates goes over the relief valve when it's not being utilized. A waste of power and generation of heat.
Your valve is "probably" open center, which allows the flow to go through the valve when it's not being used. When it's in the neutral position, normally the work ports going to the cylinder are blocked, holding the cylinder in place. A motor type valve spool is different in most cases, it may allow the motor to freewheel when the valve is in neutral.
Typically tractor hydraulics are a series system, which means as fluid leaves one valve it goes to the next in the chain, etc. Any parallel circuit will have to have it's own pump for each valve, otherwise the fluid takes the path of least resistance. The only part of the circuit that can be parallel is the "tank return" which is usually not pressurized or expected to perform any work.
You've noticed I used the words "normally", "may", and "some". That's because there are always exceptions to the "rules", correct or otherwise. There are some oddball cases out there, usually hooked up by someone that had their heart in the right place, but wasn't competent to design a system.
Your mileage may vary, I'm no expert either..

Not long ago, while at my dealer, I asked about adding hydraulics to the rear of my Kubota... nothing serious, just something to adjust the top link (think box blade) and was shocked at the response... They were estimating $1,500 just for the parts... needless to say, I walked out... Now, I ain't very smart but there ain't no way it should cost that much... what'cha think?

Dougster,
Not sure what machine you have but I added one rear remote on my MX5000 and it cost me about $800 if I remember correctly. I about cried when I saw that the OP paid $425 per...I wonder what the difference was.

I've got an L2800.. nothing exotic and wasn't planning anything other than a hydraulic top link.. hoses and cylinder,.. maybe $250? another $250 for a controller? I need to look into this again... Geez..

That price seems a little high, although it's still expensive. I was quoted about $1000 for 1 remote. I thought that was expensive until I started pricing parts. The valve was about $300, stainless piping and fittings add almost that much again, then you add the labour to install it all.
The L series is one of the lines that Kubota does not offer a remote "kit" for, you have to piece it together.

I remember reading on several threads that a single remote cost about $700-900 depending on dealer and so on. Granted this was about two years ago so add more $ for inflation. I personally lucked out. The tractor I bought had a remote installed and the owner didn't even mention it before i went to look.
The Kubota OEM remote hydraulic options for the L series are famously (or infamously ?) expensive. The Kub installation is nicely integrated into the operator's station and thus involves more labor to install, however a good hydraulics shop or knowledgeable owner can add equivalent hyd remotes for quite a bit less money. Depending on who is doing it, the end result can be a neat installation or pretty crude.

Others have explained it well so I won't repeat it. Other common terminology for your valve is "tandem center" or "work ports blocked in neutral"

on kubota build your own an L40 remote costs $233 for the double acting valve and $519 for the 1st level and base kit (plumbing to the valve). these prices are for a cab tractor, so $752 list price. I think I've been quoted around 1100-1200 for two remotes. For 3rd front valve, list is $900, I've been quoted around $750 with a new tractor. buying them separate from tractor is probably more like list price.

$1200 is nuts for a single remote I paid $450 for mine including instalation on my L3400 when I bought it in 2008. I don't think that the price went up that much since then? I did have mine instaled when I bought the tractor maybe that saved me more than I thought?
