Abstract
A latch mechanism for the trap door of a combine stone detector is disclosed wherein the latch mechanism is operable to release the trap door for ejection of a stone or other non-crop foreign matter from the feed path of the crop being harvested when the foreign matter is detected either electronically or mechanically. A release mechanism is provided to unlatch the trap door when a pinch roller forces foreign matter downwardly against the trap door. A trip mechanism is operatively connected with the release mechanism to unlatch the trap door when a signal is received from the electronic detection mechanism.
