: For standard harvesting, the engine should typically run at full throttle (approx. 2200–2400 RPM ) to ensure the hydraulic systems and threshing components have sufficient power and recovery speed.

: For detailed schematics and mechanical maintenance, you can reference the ZMAJ 142 Radionicki Prirucnik (Workshop Manual) available on Scribd . Zmaj 142 RPM

: If your dashboard tachometer is unreliable, you can use a handheld digital pulse tachometer to verify actual speeds at the pulleys. : For standard harvesting, the engine should typically

: 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

: 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%.

: Usually set between 900 and 1100 RPM . Research indicates that maximum threshing efficiency (up to 99.9%) is often achieved at 1100 RPM .
