Hey guys I am looking to add some hydraulic flow to our tractor. I talked to our service guy and he said they used to put a separate pump on these things with electric over hydraulic valve with just a switch in the cab. All it would be running is the fan on the air cart. I believe it was a atom jet pump? Then I talked to parts and they can no longer get the parts needed. Does anyone have this system or any sort of upgrade? Anyone know how I can upgrade this thing? We had a flow test done and it is putting out almost exactly 50 gpm at the moment. We are pulling 60' p2070 with 1060 cart, also 2150 gal liquid tank(no hydraulics on tank). If anyone has any thoughts or suggestions I would like to hear them. Thanks
