hydraulic question on b7100 hst

[bmwmike]

I have a 1995 B7100hst and I have a kubota loader 1640A on it. I had to alter the sub frame to make this loader fit , but i got it cheap and it was well worth it. The control valve on the loader has been leaking through and the buckets uncurls, this has gotten worse and I have decided to replace the valve. All That to ask this.

Is this and open or closed system on this model (B7100) ? I know I need the power beyond because that is what is running my power steering.

I have a race car pump I was going to use for the power steering,but I could not bring myself to cut the side panel and hood to make that work. I had loaded the rear tires and I just added wheel weights. I know everyone likes pictures so I will include some.

Since I rambled on so I will repeat my question. Is this an open or closed hydraulic system?

Your tractor has an open center hydraulic system.

Yes your tractor has a open system.

I see telescoping stabilizers on the 3 point- any chance of a closeup?

Thanks Guys,
That what I thought but I wanted to be sure before I buy a new valve.

Hazelfarm, that link is a good explanation on open and close system.

Hodge, That is the best picture I have of them, I will try to get some more pictures of them. I made them about a year ago and they work pretty good , I thought about redoing them with better square tubing, but so far they have held up.

I have a side business building them; let me know if I can share any knowledge or experience.

hodge,
Sorry it took me so long to get back to you with pictures. I have not gotten the chance to take any more , but I did enlarge the ones I posted early. I had seen some thing like these on a larger tractor and thought I would give them a try. I just made mine out of stuff I had on hand, thinking that if I liked them I would make them out of better tubeing latter. So far they have held up and worked out very well.
I enjoy making things to use with the tractor, I just made the brush bar you see in the previous pictures ( have not even painted it yet) I used it this weekend on seven big oaks I had to take down, man it works really good. I bought all the material at the scrap yard for 20 cents a pound, so total cost was about $10.00 plus about a dozen welding rods. The brush bar works so well I decided to make a tooth bar out of the same 1" 1/4 Rebar , I know it is not heated treated and won't hold up for ever. But if I get 2 to 5 years out of it for less than $10.00 and about three hours work, I will just make another one.
I made the hitch in the pictures and the wheel weight brackets. Boughts the weights at scrap yard, 20 cents a pound.
