ABSTRACT:
A dump gate assembly as for a feed mixer housing including first and second hinged gates swingable between upper closed condition and lower open condition, each gate having a cam track preferably in the form of a configurated gate stiffener cooperable with a cam follower on an actuator. The cam tracks have a portion causing greater force to be applied to the gates during the final movement of the gates to the closed condition. The actuators for the two respective gates are at opposite ends of the gates and are interconnected to cause timed gate closing. A special seal element causes a second seal between the closed gates.
