specs say 19 at auxiliary at 3000 psi. 26 gpm on the rest of the system. My Bobcat is only 85 hp but puts out 37 gpm at 3500 psi confirmed on flow meter. My mulcher is rated for between 35 and 40 gpm and it's performance is spot on for what it should be. 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.
