Abstract

The invention concerns a method of and apparatus for harvesting crops. One method involves harvesting from non-adjacent areas of land on which the crop is grown. The method comprises notionally dividing the areas of land into at least two groupings and for each region establishing a site for a cleaning mill for graff, a mixture of chaff, weed seeds and grain, harvested from said land in said region by a mobile graff harvester, cleaning graff harvested from one of said notional regions in a mobile cleaning mill provided at the site established for that region, subsequently moving said mobile cleaning mill to a site established for another of said regions, and cleaning graff harvested by a mobile graff harvester from land in said other region in said mobile cleaning mill. The invention also relates to a mobile, self-powered cleaning mill and a method of rethreshing clusters of grain and chaff within a cleaning mill.
