Abstract
Apparatus for picking up and conveying crop has a high-speed rotor 21 mounted on a mobile frame 50 for movement over the ground to pick up previously cut crop. A hood 54 extends around part of the front of the rotor and moves relative to the frame in response to the crop to effect automatic adjustment of the clearance. Heavy unwanted objects, whether metallic or non-metallic, are detected by an impact detector 25A. Metallic objects (whether large or small) are detected by an electromagnetic detector 25B. The detectors are positioned in various alternative locations, either on the moving hood, or on static portions of the frame.
