I tried your suggestions today and went a little faster with the front raised a little. It seemed to help. The track is getting levelled more each pass but I think it's just going to take lots of passes to get it as flat as we want it. The clay is mostly dry and powdery and still doesn't seem to flow over the blades as easily as you would think. We're getting a guy out to shoot it with a laser level and then work up the high spots so they'll level easier. I think if we get rain and it settles will help too.
