yes I have seen the grass stripper and that is what a lot of what I am thinking about, I took the one I made out to the water hole that still had some wheat standing in it, and tried my custom made grass stripper on the wheat, it did a good job, like said it would need further cleaning,
the wheat has been standing since July and not harvested,
I went out and tried the stripper on the water hole that did not get cut during wheat harvest, this is to day "before",
this the stripper working
after the stripper passed
this is what was in the box after wards, I think there would be way of lessing some of the chaff, as I had the screens over the boxes to catch it all
there are some Ideas I think that would improve it and cut the cost some, some would be changing the lift system and would like to make it dump(blow over) some of the light chaff.
note: the date formate is day, month, year, on the camera,
