I got a 14G with hydraulic lift. Can someone tell me the GPM and PSI this pump will put out? Thanks Jake

I couldn't find anything on the gpm. The best I found was in the repair manual. For the 931013 model, it looks to be 550 psi is where they have the pressure listed at. All the pressures and cylinder forces are the same as the hydrostatic drive models. Hope this helps.

I have never seen any hydrostatic drive lift circuit put out more than 2 to 2 1/2gpm.

I didn't see anywhere what kind of pump they used for this. Since all the specs are the same as the hydros, could they have adapted a hydro pump to it?

This is a gear drive tractor with a belt driven hydraulic pump. I took the hydraulic system off this tractor for a project I have been working on. Just didn't know what I had to work with Thanks Jake

Does the pump have any kind of tag on it? How about a picture of it.

Duh on me!  14"G" should have clued me in!  If there is no tag, then about the only cheap/easy way to determine flow rate is to catch the oil from one revolution of the pump by hand, then measure this amount, then multiply by the rpm you would be running.  So if you got like lets say 4cc of oil (easier to measure with a hypodermic syringe), you convert that to cubic inches.  That comes to .244ci. multiplied by 3600 (rpm)= 878 cubic inches....converted to gallons is 3.8gpm
