The PC-20 M-4 is a self-propelled seed treatment machine that coats seed grain with protectant solutions before sowing — the agronomic step that defends germinating crops against soil-borne disease and pests. Classified among machines for spreading and spraying liquids in agriculture, the unit operates with an inlet water pressure of about 0.7 and weighs roughly 680 kg, moving under its own power along grain heaps at the storage site.
Self-propelled operation is the defining productivity feature: the machine works through stockpiled grain without requiring the grain to be brought to it, treating seed in a continuous flow at the warehouse or elevator. Proper seed treatment is among the highest-return operations in crop production, which keeps machines of this class in steady demand wherever cereals are grown at scale.
Sold per unit at accessible equipment pricing, the PC-20 M-4 targets grain farms, seed plants, agricultural cooperatives and machinery dealers in cereal-producing regions.
