The equipment deflects a ground-cultivation cone away from brushwood by using blade turning in the cone end, and which thrusts the brushwood sideways and free of the cone, while its bottom end slides against the front of the working cord. - The blade always extend rearwards as it turns in the cone. If the machine is reversed and the blade is caught, it merely turns and lifts the cone at the same time, keeping the load on it and its mounting within moderate limits. |
