Thanks for your help on the drill clutches. All of that is working well in testing. However now I am having issues with the PWM valve. It came with the planter and got removed when I built it. The valve had 4 open ports A,B,P & T. I put pressure from the tractor on P and 1 side of the Hydraulic motor on A then returned T and the other side of the motor to the tractor. Everything works fine however it won't adjust flow to the motor to slow it down. Are my hydraulics hooked up wrong or maybe settings in the Integra? Thanks for any ideas.
