The skids specs are roughly double what the ex specs are and it also has power to move and lift a 2650 lb attachment without much rpm loss to my cutter. Somehow it works.
YellowDogSVC...I'm going to have to disagree that you'll actually see a legitimate 37gpm@3500psi on a reputable flow meter. I've done this test on a T870 with a friend of mine who is a current Bobcat salesman and his lead mechanic in his Bobcat shop. We were getting less than 12hyd hp at 3500 psi and less than 22gpm at all pressures above 3000psi. As a matter of fact, we did not see 37gpm once we got above 2100psi. Max hyd performance was around the 2500-2700psi range and the pump was producing around 31-35gpm if I remember correctly. In no scenario will you see 37gpm going through a flow meter @ 3500psi in your 85hp machine.
