View No. 2. Shows a special threshing outfit which threshes and cleans the seed at the same time. 
View No. 3. Here the seed is “water sunk” and all light or imperfectly filled seed is floated off. 
This method of grading insures the highest standard of germination in our seed 
as the light seed of low vitality floats and is taken out. 
View No. 4. All the seed that sinks is quickly removed from the vats and spread to dry before 
the moisture penetrates the seed.
