Sold my Case "HydraElectric" today and took this 400 in as a partial trade. He said it was only running on one cylinder. We couldn't get it started so had to push it out of the barn and around the corner to the trailer so I could get the winch attached. I tore something in my left arm pushing it and now can't hardly move the arm. I only have about $150. invested in it so don't feel too bad if the motor is junk. First chance I get I will pull the plugs and check the compression. It has a Kohler twin in it. I don't even know the hp of this model. It has all the hydraulics on it and the seat is like new.
