In 2017, we purchased the S-800 seed cleaner for cleaning our own wheat and barley seed production. We are a small company and use the machine to clean 80% of our seed requirement, which amounts to 16 tons per year. It’s a simple, easy-to-operate, and reliable machine at a reasonable price. We haven’t needed any spare parts in the past 7 years, only ordering a few different sizes and types of sieve plates, which were always readily available. We are completely satisfied with the machine!
