I have a 1974 Int 574 , which I have attached a loader to. I needed to know where to plumb the loader without messing up a double spool open centered valve body someone added to run a potato harvester. This valve is plumbed in under the seat. I have done a pressure check on the valve on the left side with the filter on it and cannot find a port with pressure that is not being used. The tractor the loader came off of had the return running into the bottom of the rear end housing and the pressure came off the right side near the leaver top raise the 3 point hitch.Thank you for your help!
disconnect the 3 point hitch and connect the pipes to the loader lift arms
