I just bought a 1988 chevy dump truck with an 8.5 western plow. I am totally new to plowing so I wanted to hook it up and plow my driveway. I got it hooked up but seems when I drop the plow it goes down to far, picks up the front end nearly digs a hole lol What did I do in setting it up? I thought one simply pressed down on the controls and were ready to go. To make this work once I hit pavement with the plow I then have to raise it a bit, real PITA.....any help?
