Does anyone know the gallons per minute flow rate on a John Deere 140H3?

Looking at possibly making a small 3 point log splitter but don't know if there is enough flow/pressure to make it worth while.

Thanks,
Bill

Not enough of either Bill. Flow is like 2 1/2gpm tops, and pressure is around 750 to 850psi.

I have the "Service Manual for the 140 (Serial No. 30,001 - ). I didn't find anything about gallons per minute flow rate, but I did find this info about how it works and the oil pressure it maintains.

The sundstrand 15 manual may give the exact figures. I think you would need to run a pump off the PTO to get enough flow to run a log splitter. That can be done and it works well.

The guys are correct- to bust only 20 ton at 500 psi working pressure, you would need a cylinder with a 10 Inch piston. Also, if you need a stroke of, say 24 inches, that cylinder would contain 3.46 gallons, so at 2 1/2 gpm, it would take 1 minute, 20 seconds to stroke it. :orangecool:

Thanks for the replies. I thought it was a long shot. I'll save the parts and plans for the Copar Panzer project
