142 Rpm: Zmaj

: Higher drum speeds increase threshing capacity but also lead to a higher percentage of broken grains. For instance, increasing peripheral speed from 26.7 m/s to 33 m/s can drop the "whole grain" percentage from roughly 96% to 77%.

: As drum RPM increases, cleaning efficiency generally improves, though this must be balanced against the risk of blowing grain out of the back of the machine. Adjustment & Maintenance Zmaj 142 RPM

: Use the drum variator to fine-tune RPM while the machine is running. If you experience grain loss in the straw, slightly increase the RPM; if you see cracked grain in the tank, decrease it. : Higher drum speeds increase threshing capacity but
