 Hydraulic Flow and GPM rating

I need to know what the Hydraulic GPM rating is for a Yanmar YM2010D, a YM1500D and a Mitsubishi D1600D tractor is.

Also, can anyone tell me if it is possible increase this rating with auxiliary pumps or other means. Is it difficult and expensive?

I would very much appreciate any information that anyone might have on this.

 Hydraulic Flow and GPM rating

The pump's volume and max pressure will be rated on the pump in metric units. They are not hard to convert. I don't have a list of these, but I think the 2010 will flow around 6-7gpm at 2400rpm, and I'd guess the 1500 is around 4-5gpm.

A PTO pump could be added to generate a lot of flow easily.

 Hydraulic Flow and GPM rating

Liters to U.S. Gallon conversion is 3.875 to 1. Pressure conversion probably isn't too important but it likely would be bars to psi, and that conversion escapes me.

Dave's suggestion of a PTO pump is the most realistic solution I'm aware of. I think some pto pumps have a continuation of the pto shaft so a pto implement could be used when the pump is mounted. Shorter pto shafts would be needed though. The size and weight of a separate reservoir would be on the tractor and I don't know how difficult it is to remove one if desired.

Substitution of a different pump for the existing one is unlikely because the mounts and drives are almost unique to a tractor model. The hydraulics of supplemental pumps is tricky and one would be difficult to mount a drive anyway. JD does have a system where the PS and hydraulic pumps are twinned during high hydraulic loads, but there's already a second pump and the system doesn't increase flow during moderate loads.
