Abstract
A trip mechanism, cooperable with an electronic stone detection device on a combine, is disclosed wherein, upon the reception of a signal from the electronic stone detection device indicating that a stone has been detected in the feed path of the crop being harvested, the trip mechanism is operable to effect an unlatching of the trap door to permit the stone to be ejected from the feed path. The trip mechanism includes a solenoid for receiving the signal from the electronic stone detector and for engaging a trip link with a rotating cam member. The cam member causes the trip link to engage a release mechanism which disconnects a latching device from the trap door so that it can move to an open position.
