Maybe someone can chime in here, I have a Allis Chalmers D14 with a trip bucket and want to convert the trip bucket to a hydraulic operated bucket, of course the trip buckets have only a one way cylinder to lift the loader when you pull the lever on the steering column to lower the bucket the hydraulics just release without pressure on the cylinder. I have purchased a hydraulic pump to run off the PTO which means there will be constant pressure when it is operating to be set up with a tank operating valves relief valve and filter. How can I operate the one way cylinder with a system under constant pressure, or will I have to purchase 2 new two way cylinders for the bucket.
