[AT] Tractor Hydraulics

[carl gogol]

Mark-
I added a front pump a few years ago on a D-14.  I think the capacity was 12 
GPM at 1800 RPM.  This should make your loader with 2.5" hydraulic cylinders 
jump too!  It is actually easy to do a calculation to see how long it will 
take to fill a pair of cylinders 2.5" in diameter by x inches long at 12 
GPM.  I would say that a pump between 10 and 16 GPM will work just dandy on 
a loader.  The only drawback with too much capacity is it is hard to do any 
fine grading as small movements aren't easy to control.
