Has anyone used one of these and what was you experence? Thinking about trying one out here. We are making too many passes over the field and looking at one of these. We are in SE washington and have a silt loam type soil. Right now on irrigated acres we are plowing in Dec/Jan. Discing right after. Culivating in Feb, then packing twice. In other words burning alot of diesel and compacting the soil. Father isn't too interested in changing the operation. But things change might demo one next year. Also has anyone used it after harvest to kill weeds like Russian thistle and Kosha?
