I just hooked up to a 2433 Sunflower chisel that my dealer brought out a while back to let us try. My problem with it is that while going through the field one of the wing cylinders will start to raise. So I stop and rephase the cylinders, getting going again and it will do the same thing. While raised if not holding the hyd. remote in the cab up the chisel will start to leak slowly down. We broke lines lose at the cylinder trying to relieve air but that did not help. I finally decided that there must be a busted seal inside the cylider letting oil leak by. I'm going to look at my Sunflower disk tommarow to see if I can borrow a cylider off of it. Anyone have any ideas on why this is happening?
