Tractor-drawn rotary rake for hay swathing, includes active control of outrigger angle to enforce overlap of circular raking action during tight turns

摘要

An actuator and/or switch unit are provided near the front outrigger. In accordance with departure of the trailing angle of the outrigger (11) measured at the front circular rake (4) from a predetermined value, the outrigger angle is reduced, using e.g. a hydraulic cylinder.
