 BX 23 Hydraulic Question

I'm a new member to Tractor Point, been around for a while, but just signed up so I can ask some questions. I have a BX23 and want to add a hydraulic cylindar to the back for use as a top link. Using appropriate connectors, can I use the backhoe ports to connect to the control valve? If so, which one is the pressure side, and which is the return? I've also been scratching my head trying to figure out if this thing has an Open Center or Closed Center Hydro system. I think it is Open, but want the experts to tell me I am right. Help is appreciated.

 BX 23 Hydraulic Question

I am repeating this from my original post re a hydraulic top link for a BX series tractor:

" Yes, there is a lot of talk and chat on the Internet. However, to this date, I haven't seen one actually installed on a B series tractor.

The product IS NOT recommend by any of the mfg.s for use on tractors this size (BX or B series).
The reasons seem to be:
1. increased likelihood for damages to tractor and implement lift and hitch
parts
2. the implements positioning on the TOP LINK is easy to reach and use
without the use of hydraulics
3. these size Kubota tractors do not have the remote valves
4. lack of demand from the shoppers in the market

Since the attachment is not recommended, and damages should happen to occur to the tractor ... the warranty issues maybe challenged and I cannot recommended that a customer take that important risk. Consequently, we do not offer them as an option at this time.

I would really appreciate a report from any customer that has installed one of the kits (on their own) as to satisfaction level after installing and using it a while.

We are open to adding and selling the option in the future (however a purchaser may need to sign a note concerning the warranty issues acknowledgment."

Thanks so much.
We appreciate your continued business.

 BX 23 Hydraulic Question

I wasn't asking for advice on whether or not I shoud do it. I know what I am doing, and why I want it.

My question was surrounding the actual design of the hydraulic system, and what type of valve I would need should I want to add one using the backhoe ports. I'm batting around ideas, and want to know what my capabilities are.

I am not asking for someone to supply this, nor would I ever ask my dealer to cover any modified portions of my tractor under warranty.

Anyone with an intimate knowlege of the hydraulic system have an answer for me?

Thanks,

 BX 23 Hydraulic Question

I have a similar plumbing set-up on my 4115 and I used to have a BX22. The is no problem with what you are proposing.

See my comments under "Top Link Sugestions" for more info.

 BX 23 Hydraulic Question

My understanding was that you also have to plumb a return line to the sump, in addtion to using the "to" and "from" connections for the BH. Don't you also have to use open center valves for this application? I'm also interested in building a top 'n' tilt setup for my BX22. Any help y'all can offer would be greatly appreciated.

 BX 23 Hydraulic Question

Thanks for the replies, I didn't understand either how it would put any more stress on the tractor or implement than a stationary top link, unless you got really crazy with it.

So, to build my own I need an appropriately sized cylindar, Open Center Valve (?), and hoses/fittings to plumb into the backhoe ports. Do you need a third line, or is the in/out backhoe ports all I need to plumb in? I do quite a bit of box blade work (4'), and spend most of my time stopping and turning the link in or out which gets very tedious.

Thanks for your help. So far I have gotten quite a bit of help from you guys.

 BX 23 Hydraulic Question

You would attach your hydraulic port "out" line to an open center valve block and complete the circuit back to the port. The goal is to have a continuous, pressurized flow to the valve block any time the tractor is running.

The Tn'T hydraulic cylinders are run off of the valve block.

Your backhoe runs in the same manner. There is hydraulic pressure and flow running through the valve block any time the tractor is running whether you are using the backhoe or not.

 BX 23 Hydraulic Question

Adding another valve in series in a hydraulic circuit requires 3 ports. In - from the power beyond port of the upstream valve; PB - back to the hydraulic block or "in" port on the next valve in the series; and Out - directly back to the reservoir. The last valve in a series, or a single valve cicuit, does not require a PB port.

 BX 23 Hydraulic Question

I might be confused, but.....

My BX22 had an "in" and "out" for the backhoe and no third line. If you do not have the lines hooked to an open center valve they have to be coupled together or the tractor makes some very unpleasant noises.

Ditto for my 4115. In and out.

When my Tn'T is hooked up in place of the backhoe or the log splitter.... the valve block is warm to the touch, and downright hot in the summer, even if I have not moved either cylinder control since start-up.

 BX 23 Hydraulic Question

You cannot use the hydraulic connections for the BX23TLB backhoe for a hydro toplink so I bought a standard Kubota remote top link kit for my BX23TLB from my Kubota dealer for less than it would cost putting one together myself. Came complete with hoses, control valve that clamps to the ROPS and good instruction on how to fit.
