The purpose of this seed washing machine is to simulate the cleaning, drying, and treatment of grain seeds for use in a planter or seeder.
Only one variety of grain may be kept for processing at a time in order to preserve realism. The "Prices Screen" shows the grain fill level, which may be taken out of the seed cleaner if necessary.
