Working up a Snow Covered Field In this video I am out in the field with a John Deere 9420R tractor pulling a 25 foot wide Versatile Fury high speed disk. The field in this video had winter wheat on it which was harvested back in June then after harvest the field was seeded with a cover crop mix of oats and sunflowers. It started snowing on this morning and we were curious how this would all work up in the snow.
