Abstract
A ferrous material detector operably associated with a crop harvesting machine including a signal generating means operably associated with the compressing means of a harvester. The signal generating means generates a signal during the normal operation of the harvester and interrupts the signal whenever undesirable objects pass in the vicinity of the compressing means. The ferrous material detector also includes a drive system interrupting means which is activated whenever the signal is interrupted.
Claims22
A crop harvesting machine comprising:
- a. a frame adapted to travel across a field;
- b. means mounted to the frame for delivering crop material from the field to said frame;
- c. means positioned rearwardly of the delivering means and mounted on said frame for processing the crop material delivered to said frame;
- d. means operably associated with the processing means and positioned between said delivering means and said processing means to compress said crop material;
- e. means for detecting ferrous metal in the immediate vicinity of said compressing means between said delivery means and said processing means;
- and
- f. means for interrupting the operation of the harvesting machine, said interrupting means being responsive to the detection of ferrous metal in the vicinity of the comprising means by said detecting means.
