The work done on the combined harvester-thresher by this station during the past two seasons indicated that windrowing grain or similar method is likely to be a very desirable practice in South Dakota. Previous work indicates that a very large percentage of the high moisture content found in grain that was direct combined is due to green weeds. Pigeon grass and other weeds found in the stubble bottom, green tips from the Russian thistle and other weeds seem to be the source of most of this excess moisture. The windrow method would solve this problem and reduce the moisture content of the grain itself.
