Bradco 715 front blade attachment

EXACTLY!!

Your valve is now plumbed with power beyond and tank returns. Dump those rear outlets and find a pernanent connection for the tank return.

Thank you!

Thank you!

You are more than welcome. It was a fun puzzle.

BTW - I think you will find the inlet relief on your valve is set lower than the main relief on the tractor. Thats going to reduce your 3pt lit capacity. I would suggest bumping the valve up to somethung greater than the tractor.

I couldn’t keep up with the routing of the hoses and what he tested or changed. I also don’t understand what rear remotes were on the tractor.

Would you please sketch what you understand he had hooked up to begin with and then what he ended up with (which I think is just the front blade valve being correctly connected).

What is inlet A on the tractor? What is outlet B on the tractor? Those terms are a bit strange and I just want to be sure I understand what they are correctly.

What is “out” on the valve? Again I “think“ I know but just want to make sure.

I guess a secret decoder list of terms that mean the same things would be good to post as a sticky thread if you think it would be beneficial to many.

The main problem was lack of documentation for both the valve abd outlet block.

Kubota has historicaly done a poor job with terminology. In this case inlet A is power beyond from the implement and outlet B is pump pressure to implement.

His (and my) first mistake was getting A and B reversed. That was immediatly resolved when he posted a picture of the instruction decal

The OUT on the valve plus rhe two rear couplers was always suspicious. OUT turned out to be tank return and the underside port is power beyond.

Power beyond was going to a rear outlet and deadheaded.

OUT was showing flow because the inlet relief in the valve is set lower than the tractor relief and the deadheaded inlet was unloading to tank (OUT). I knew that was a possubilty when he ran the test but he reported no pump or relief noise so...

As soon as the power beyond was moved to IN on the hydraulic block all was well

You think this would be worthwhile? Its PoTreeBoy's inside joke. The cover page is all there is right now

Yes anything that explains the different ways Kubota has done with hydraulics would be good. I get caught up in thinking they would have done consistent things but they see to change methods over years and in larger tractors.

I think the larger tractors have much more internal piping than the smaller tractors, but that may be an old versus new thing also.

The different terms used are also confusing and I have never found anything that lists the different terms.

I have seen many people hook up the hydraulics incorrectly so a diagram showing the proper flow (in general) would be easy to direct people to instead of having to try and explain it in words.

But I understand that it is difficult to get things into postings and not have an error or confusion.

Thank you for your explanation above, very helpful.
