: Optimal results have been found at roughly 750 RPM using a rasp bar drum. Operational Impact of RPM
: 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%.
: Operating at higher engine RPMs allows the hydraulic pump to recover pressure faster during intensive tasks like steering or operating the header.
: Lower speeds are required to prevent grain breakage, often ranging from 400 to 600 RPM .
