All good ideas. One thing about this project is the field had previously been let go. I disced it last summer. I was mostly 5-6 ft tall Mustard. So while the disc knocked it all down there was a lot of debris left on the surface. I tried the land plane but in 40ft it was clogged with the debris and holding dirt instead of letting it pass over the blades. So ~
I went to my buddy's place today and picked up a 3/4 x 8 inch inch dozer cutting blade. Weight is 200 pounds plus. I'm going to rig this up and give it a go... a more or less free attempt to solve the problem...
I do like that 6 ft culti-packer but the price - not so much. No used one around.
My mig is out of gas so no more progress today beyond ideas, keep em coming.
