Need help hooking up backhoe attachment

[Built to last]

I have a International 464 Diesel tractor that I want to put a backhoe attachment on. My problems is hooking up hydraulics. I just bought a Bush Hog 862 backhoe attachment that still has the original paint on the bucket and has been sitting in a barn. It was originally on a skid steer.
My tractor has two steel hydraulic line that are capped off at the rear of the tractor and I hoping someone can tell me if I can run the backhoe from them. I know I will have to get couplers to match the one on the backhoe. Actually hooking the backhoe up to the tractor is not going to be a problem. Just the running hydraulics and I really can't afford to buy a pto hydraulic pump right now.
If anyone or everyone can help I would really appreciate it.
Thanks

Do you know if the hyd on your tractor are open center hyd?

If the BH hyd and the tractor hyd are the same, then you should be able to plug into one of the remotes QD's and bungee the lever to operate that work port.

If your BH is a two hose BH, plug the IN/pressure hose to the A work port at on the remotes.

Run the BH OUT hose to the hyd fill cap.

If the BH is a three hose unit, we can make other arrangements.

I am going to try and post pictures of both. The two capped hoses on the tractor go to some sort of box beside the controls for the three point hitch,etc but I can't see any kind of lever,etc to turn them on or off. I can build any type of furniture, build my own sawmill, etc but when it comes to hydraulics, I'm lost. Thanks so much for you help.

I'm not sure if I replied to your message or if I just added another reply. Anyway, I posted some pictures and any advice you can give me is greatly appreciated.

How to you tell if it is an open center system or not. The tractor is a 1973 model I think if that helps.

Can you identify which line is the pressure line. You could use a hyd gage and find out.

Do you have a lever/valve to control the fluid to the two lines that have plugs in them.

The simple way to connect the BH is this, since your BH is a two hose BH, you need one pressure line going to the BH IN hose, and then run the other BH hose to the tractor fill cap.

J.J. is on the right track. I cant help but think that there is a lever next to the right fender (next to the 3 point lever?) to operate a rear remote. the only thing here is that someone caped off the lines instead of installing a pair of quick couplers. Do you have a lever/valve that doesnt seem to do anything? if so, then my money says that lever runs the rear remote. Its not very likely that your tractor has a closed center hydraulics.
Keep us posted on what you find.

One way to tell if the hyd system is open center or closed center is to install a hyd gage in a tee in the IN port of the first valve, and if all valve levers are in neutral, the open center system will have very low to no pressure.

A closed center hyd system will have high pressure or standby pressure.

Thank you guys so much!!!!!!!!! I took a cover off and looked where Steve was talking about and found a thing under there (don't know what you call it) that was supposed to have a lever, but there was just a nail in it. Where its located looks like your foot would hit it a lot and I know the guy that had it the last 10 years or so never used anything with hydraulics, so I figure it either broke or they took it off.
I still not sure if it works but I have faith it will. So far there hasn't been anything on this old tractor that hasn't worked. I've had it about a year and a half and its never even used a drop of oil and I run it pretty hard at least 2 or 3 times a week. I built a set of forks for the 3 point hitch out of an old forklift and use it to move logs and lumber around for my bandsaw mill.
Since forks are about all I use, every once in a while a finish mower or a scoop for cleaning out a ditch, don't you think I could also use this connection for a cylinder where the top link is to make my forks tilt.
I believe I'm going to be able to just take the forks off and make up something so the backhoe will mount on the thing the forks mount on. Since it was on a skid steer before I have to change things around anyway.
Once I get the caps off tomorrow, I will go to Tractor Supply and try and figure out what connections I need to put on the tractor to hook to the backhoe and I will let you guys know if it works. I need the hydraulics to work before a build something to mount it to.
I don't have or know anyone that has a hydraulic gauge to hook to it so does anyone have a idea on how I tell which one of the tractor line is the pressure side or in side ???????????
Thanks again, J_J and Steve you have both been a tremendous help!!!!!!!!!

You need to find out how many GPM your tractor puts out and if the internal hyd's. have enough capacity without overheating. The way to make a hoe operate smoothly is to use 2 controls at the same time whenever possible. If you don't have enough hyd. flow it can be frustrating. A skid steer almost has too much flow for a backhoe but you can throttle down.

Thanks Arc weld
I've owned a couple of backhoe attachments that were on my skid steers but this is my first tractor and first time putting a backhow attachment on a tractor. I know the backhoe needs about 6 to 8 GPM so I'm hoping the tractor will supply enough for it. If for some reason I can't get it to work right on the tractor, I've been thinking about making it a towable BH since I have an engine and all I would need is a 8gpm pump. But, I hoping once I get the coupling I need and hook it up it will work. I have my fingers crossed anyway.
Thanks again!!

To compute GPM.

A good trick is to put a clean milk jug in the 5 gal bucket, and time the 1 gal first.

Time the hyd flow from a hose in a 5 gal bucket and you will know the GPM at full engine rpm. Use the port /hose that you will use with the BH.

If you can flow 5.0 gal------30 sec = 10 GPM
If you can flow 5.0 gal------1 min = 5 GPM
If you can flow 1.0 gal----- 10 sec = 6 GPM.
If you can flow 2.0 gal----- 10 sec = 12 GPM

Ok, I'm back working on my backhoe again, finally!!!! I got sick again and havn't been able to do anything for the last few weeks. I figured out the hydraulic lines and went and bought some tractor quick coupling and took off the ones that were on the backhoe. They were the type for a bobcat and it cost more for just one set (one male one female) than what I could buy 6 sets of the tractor type. I was able to mount the backhoe to my forklift setup, the only thing I had to do was cut off the part on the bottom on the backhoe attachment the the rod would go through when you push the lever down on a bobcat. The top slips right in the inverted v part on top just like a bobcat would. I then welded a piece of angle on each side and drilled holes through it and the backhoe so that I can use two 1/2" bolts on each side. That keeps the backhoe from lifting up or moving side to side. Then I used the original bobcat fasteners that fit in a u piece welded on the backhoe and extended them down to the reinforced lifting arms I have on the tractor. All that works great and is fairly easy to hook up.
Now my problem is, the backhoe is a lot slower than it should be. I have to make sure the lever on the hydraulic thing on the right hand side of the tractor where the lines go to the back of the tractor is all the way in and can't come out any at all or it will slow down even more or if it comes out to far, the backhoe won't work at all. I'm going to a grand opening of a new Tractor Supply in Bessemer Alabama in the morning and get new filters and hydraulic fluid. I hope that will help if not, then I don't know what to do. Would a power beyond port make any difference. I want to add another hydraulic lever so that when I'm not using the backhoe, I can replace my top link with a hydraulic cylinder, that way I can tilt my forks some and make picking up logs and setting then on the mill easier.
Any suggestions would be appreciated.
The backhoe will dig but like I said its kinda slow and doesn't seem to have the power it should. I've owned a couple of backhoes that were mounted on bobcats and this is the same size and type as the others I've had but right now something is just not right. I believe I saw in the manual the other day that the tractor is a 8gpm pump and the backhoe says not to use over 12gpm. While I'm not as concerned about speed as I am strength. I need to put a thumb on it to pick up end pieces, etc on logs since I'm no longer able to pick up much at all myself.
