: 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.
: Operating at higher engine RPMs allows the hydraulic pump to recover pressure faster during intensive tasks like steering or operating the header. Zmaj 142 RPM
: Lower speeds are required to prevent grain breakage, often ranging from 400 to 600 RPM . : Use the drum variator to fine-tune RPM
