Adding rear hydraulic connection to BX2670

[hillsandtrees]

Yes, I have done a search but haven't been able to come with an answer.

I just got a BX2670 with the FEL to maintain about 8 acres, 3 of which are lawn/meadow, the rest trees. I would like to use the little machine to occasionally drag out some firewood. Not serious logging, just cutting down some smaller trees and turning them into firewood. For that job, there are two implements I am thinking about getting:

- A Wallenstein FX35 hydraulic skidding winch
- A 3-point mounted log-splitter

I have found lots of references on how to install remotes, including references to the factory parts kits with the valve block and hoses etc. Now both a log-splitter and the winch come with their own control valve as you dont operate them from the tractor operating station, so from my understanding of the hydraulic system, what I need is not a remote, but rather a 'wet tap' with constant pressure on one connector and a return line on the other.

So this leads to two questions:


- Is there a reasonably straightforward way to get hydraulic power to the back of the tractor without installing the complete remote kit ?

or

- Would the remote kit be able to provide constant pressure to drive those implements (by putting the valve into a detent) ?

A "Wet Tap" on a tractor is called "Power Beyond", that may aid in your search. It's the same connections used to power a backhoe. Have you considered a PTO powered winch like the Farmi brand? Should be considerably cheaper than a hydraulic one.

Ah, that should help me to get further. If I understand it right, a PB is more than just a pressurized plug, it is a loop that contains flow and dumps back into the tank. Currently, the tractor has 3 hydraulic functions: The 'joystick' control for the FEL and the 3PH level control. So if I wanted to plumb the logsplitter or winch into the PB circuit, they would need to have a PB valve themselves.

Yeah, I dont have a backhoe. That would probably make it easier.

The price is about the same. There are two reasons I am thinking about the FX35 rather than a PTO winch:
- the smallest Farmi (JL290) is 140lb heavier than the FX35 and 2.5ft taller. With the limited lift capacity of this lightweight tractor, it would eat considerably into what I can skid.
- while the mechanical clutch is supposed to protect it, I am not comfortable putting the kinds of shock-loads a skidding winch creates onto the little gearbox in the back of the BX.

Maybe it's not a good idea to start with to start with to use this glorified lawnmower to go logging, and I know that.

In would not recommend a log splitter unless you run a separate pto pump. you need to be in the 12-15 gpm range to run a splitter at normal speeds, the little bx's just don't have the gpm to run high demand hydraulics.

Good point. Probably better off with a standalone log-splitter. That way I also have use of the tractor to move the logs and split wood around.

You can't have a "pressurized" plug so to speak, your tractor has open center hydraulics so you can never interrupt that flow, the pump is always pumping.

Is there a way to hook up an implement that has its own control valve (in this case a Walkenstein FX35 skidding winch).

Yes, you plumb it "inline" on the power beyond circuit-as I wrote it's just like a backhoe gets plumbed in. I am not familiar enough with your machine, but most Kubota's have a block under the floorboard where this can be extended to the rear. Follow the three hoses from the loader valve and see where they come from...one of those ports should be marked "PB", "B", or maybe "BYD"

If I understand this system correctly, this would mean that the 6gpm hydraulic flow would go through the loader control, the 3PH control, then the winch and return to the tank. If you actuate the control valve on the winch, the flow is routed from the PB channel through the winch motor and back into the return line.

What happens if the winch is not plugged in ? Does this system require some sort of connector to run the PB back into the tank if no implement is hooked up or would one typically add a valve that routes the fluid back to the tank to bypass the plugin ?

If no implement is on the rear that requires hydraulics, the two PB lines are "looped" or hooked together to keep the continuous flow (post #6 above). Please do some searching-there are hundreds of threads on this-not necessary pertaining to your 2370, but the theory is the same for every tractor. What your doing is no different than the many "adding a rear remote" threads, just your valve is mounted on the implement and not the tractor.

Here is the way JD does it:
