As I have mentioned in earlier post, I have acquired a 3 point hitch for the H. The hydrolic lines did not come with it. It has two cylidners that will have to be hooked up to the hydrolic system.

So, somehow, I must have a line fabricated to go from the fitting on the pump housing, back across the deck under the seat and split with a "T" of some kind to supply eacy cylinder.

I don't have any experience with fabricating hydrolic lines. The fitting in the elbow off the pump seems to have a regular pipe threat in it. So, I will look around and hunt an end fitting to be put on the supply line that fits that elbow and then run it to a manifold of some nature in the rear. It seems to me, that the maniforld in the rear should have 2 quick disconnect fittings for the supply lines to the Cylinders.

What I am doing here is asking for specific recommendtions regarding the selection of the fittings and the fabrication of the lines. Can anyone help? (I can get the local NAPA store to install the fittings on the lines)

If your 3pth is like a Worksaver brand, you only need one 3 or 3.5" cylinder. Two cylinders are fine but it is overkill especially on a H. In order to use the lifting capacity of two cylinders, the front of the H will have to be heavily weighted

You can make your own hoses with "reusable" hydraulic fittings. Not sure where you get them anymore but I might look in some catalogs like Graingers.

Alternatively, you might want to take your H down to the hose maker and he can give you the best layout and fittings. The hose will be the correct length. If you go single acting with one cylinder, you will only need one hose. Places like the Surplus Center in Lincoln, NE have good ready-made hoses at cheap prices. Some they make in standard increments and others are new surplus with random lengths.

You might also want to consider getting the IH part that covers the hose(s) on the rear frame lid. Not necessary but adds a nice touch.

My solutiion to cheap hoses is to collect discarded hoses, new or used, from auctions, friends, etc and have my local hose fabricator cut and install a new fitting at the cut.

As he noted in an earlier post his hitch is a Saginaw, two cylinders. Overkill for an H yes, but Saginaw makes only one hitch for the H through the 450. I have one Saginaw for an H and one for a C. The one on my C is not that much lighter and has only one cylinder. Saginaw doesn't advertise it, but the C hitch will fit the H and vice versa. I believe the lower arms are long enough, but I have never measured them. (H-450 hitch on a C is extreme overkill) I have my hoses made at a specialized hydraulic place. They refuse to repair hoses because they don't want to be liable if an old hose gets a pinhole and causes injury. I have tried to get them to repair hoses that had simply rubbed against something or had a leaking fitting for whatever reason, and they refused. Of course they make much more money on a new hose as their hoses aren't cheap, but they are quality hoses. I realize that some implements have had the same hoses on them for 30-40 years. I have also seen those hoses break. Luckily I was not in the path of the fluid. I had one break right next to my leg on my M once. It was a break and not a pinhole. Got saturated with oil, but that was all.

I think the likelyhood of sustaining an injury from a ruptured hose is probably less than being injured in an automobile accident on any given day. I have had neither misfortune.

Your hose man is giving you a "hose job". I would find another. I have the luxury of being in an area where I am sure there must be fifty hose presses within a ten mile radius. Heck, I almost bought the hydraulic inventory and tools from a manufacturing plant that was liquidated at an auction. Your cost to buy 10 hoses probably would have been a winning bid. I didn't buy because I usually have 100-150 hoses and most times I will find one that fits with the right fitting. If that is not possible, I will cut it to lenght and have my hose man attach a new fitting. I doubt if I have more than a dollar invested in each unused hose in my inventory.

A neighbor just built a log splitter for less than $100. He splurged on a new log splitter valve for $75. Everything else came from a junk yard and that includes hoses from a forklift and a 5" cylinder from a dump truck. I guess he is friendly with the salvage yard operator.

AFTER I get this piece of red equipment setting on my work bench, I am getting advice from everywhere. The last one today cautioned me that the unit will make the H unsafe because it makes the cg change. Have you had any difficulty with the one that you are running on your H?

Any tractor, old or new with a hitch too high, and front end too light is subject to loss of control. Use common sense.

That's why ballast was invented. Ships can roll over, and do, when they are not weighted properly. Think about adding liquid to tires, wheel weights, suitcase weights, roll-over protection, etc. Sell the tractor if you do not feel safe.

Go to Wally World and buy their tractor. You, or your heirs, can sue them if you get injured.

Any tractor dealer can make any size hose you want, they will fit and won't leak, they will be safe for years. You can find ready made hoses at a farm store, but they won't be the correct length nor will they last as long as the ones you have made. Don't try to make them yourself, those will be high pressure lines and if one develops a sudden leak you will get an injection of oil into the nearest body part. The quick disconnects can be bought anywhere, but you don't need them unless you need those outlets for something else. Use the tee to split near the cylinders, not at the outlet, less line that way. You can attach the tee to the rockshaft with plastic ties, hose clamps, etc.

Also, if you don't have a spool valve, just the usual one way hydraulics (all you need for a 3 point, any way), after the tee, you need only a single line to each cylinder. Vent the "down" ports on the cylinders, if not so equipped.

Don't go to NAPA, someone on another post payed more than twice what they should have for hoses. Reusable fittings are for emergency repairs and are not designed for as much pressure as crimp on fittings. Run one line to your spool valve and tee after that as was mentioned. If you do it right it will be trouble free for years. A good hydraulics store can help you way more than a place like Napa that specializes in cars. They would also have a wider selection of hose and fittings. Hope this helps. Dave

Reusuables are not an emergency repair. My only caveat on them is you should have someone teach you to install them. A beginner can make mistakes and think he has a good hose assembly. One should also bear in mind that an H cannot develop the pressure that might rupture a proper reusable installation.
