Farmall H belly mount hydraulic pump specifications

Does anyone know what the pressure and flow rate of the belly mount hydraulic pump is on a Farmall H?

im sure someone will correct me if im wrong but I think the earlier ones were 600 psi and the later were 800 psi don't know nuthin bout flow rate

That sounds close.

I would agree with the others on the pressure, an earlier one might have the upgrade to increase the pressure.

The flow was low, maybe 3-5 GPM.

I think the early ones were only a couple hundred pounds, just enough for front mount cultivators and for later ones the 800# sounds abought right. It would lift our Case mower-conditioner OK but whan went to use a lowner gehl unit the different way it was made by lifting the complete unit instead of just the header it would not do it with a 3" cylinder Ours was a 41 Model H bought in 49 and hydrolic only added in 78 as did not have hydrolics before and just added them for that mower-conditioner. It supposedly was traded into dealer with hand lift cultivators that grandpa did not buy with the tractor. It did have a cracked and welded center of tractor from supposedly having a loader on it. That crack had not caused any problems when we traded it off in 84 for a tractor of twice the horsepower. That was for heavy tillage after the dairy heard had left in 80. And you could not give me a 3 point hitch for one, better without it. And never missed live PTO or power steering either. Only thing I wished it had the 9 speed transmission as 4th was to slow ground speed for too high engine speed for hay rake. And way to much gap between 4th and 5th on road hauling grain to elevator. That is where the 9 speed would have made it better.

My H belly would lift a 6 row 7000 planter, but not the marker arms.

The H my dad had would lift a John Deere 494 planter fully loaded with fertilizer and insecticide boxes, and extensions on the seed boxes.

If you are serious about getting an H, consider getting an inexpensive I&T service manual to get to know the machine, #IH-8. Should be between $10 and $20 new. An operators manual may help too.

I have measured the pressure that mine produces to be 900 PSI at half throttle. The max flow rate is between 8 and 9 gallons a minute by my
calculations based on observation and calculations. I do not have a flow meter. I calculate the volume of the remote hydraulic cylinder and then time
how long it takes the tractor pump to make the cylinder travel a given distance. I am timing it with a stopwatch. I know this is not completely accurate,
but I must be fairly close.
