[Farmall] Farmall H hydraulics

[Barney Van De Weert]

Jerry, there are 3 ports on the H pump, 2 are the same hooked together, one on the right and one on the left. They are a single acting system. When you pull the control lever back they are pressurized, you release it and they hold. Push it forward and it allows the oil to free flow back into the reservoir, the implement pushes the cylinder back to push the oil back to the reservoir. The 3rd outlet is a delayed circuit that would be used with a front and rear mounted cultivator or similar tool. It is the one on the left and I think is the rear one. The normal outlet would raise the front implement then the back would raise after that  by the 2n or delayed port. 
 
To do what you want to do you will need a valve connected to the pump port, could be as many spools as you want, and also need to route a return to the hydraulic unit usually the fill tube is used, I'd also add a filter after the valve on the low pressure side. You will also need to have the control lever on the tractor pulled and held back when you wanted to use the system. 
 
You should be able to find the parts you would need at most tractor supply stores, parts catalogs or Dealers. Don't forget possibly tractor junk yards as well as the Internet.

Hello.

Could someone point me in the direction of how I go about setting up the
hydraulics on a Farmall H.  I'd like to add 3 point to the tractor, but I'm
looking for information on which side is in and out on the tractor.  Also I
was curious to know if I should use a monoblock control for up and down
pressure.  I'm considering getting a two level system so I can run the 3
point plus have aux hyd in the back for whatever may be attached to 3 point.
Feel free to point out certain brands or stores that would be best for
getting these parts... I assume a Tractor Supply Store would work?

Thanks,

Jerry
