I have searched the net with no luck. I am sure its an easy find but I am not finding it. I am looking at post drivers and I am trying to find the flow rate @ __ PSI on a MF 230 and a CASE 485. Tractor data has the Case 485 @ 15.9 gpm but no PSI listed. The MF230 I cant find anything about the hydraulic ratings. So does anyone know where to look and find this info?
