Abstract
The disclosure relates to a concave latch mechanism for an agricultural combine. The invention consists of concave surrounding a rotor. The concave has a concave pin and an adjust pin. The adjust pin is inserted into a support slot located in the frame. The concave pin is inserted into a handle also located on the frame. The handle has a lever which orients a curved cradle plate which supports the concave pin. When the lever is released, the cradle plate correctly orients the concave pin with the handle. The concave pin enters the cradle plate through an aperture. The aperture can have a sloped lead-in which assists in the positioning of the concave pin. The handle can also have an isolation mount between a portion of the handle and the frame. This isolation mount helps minimize vibrational noise from the rotor.
