- 10- PICKER GRATE FOR A ROCK PICKER ABSTRACT OF THE DISCLOSURE A rock picker includes a picker grate having a plurality of picker bars extending in a curved path forwardly and downwardly to a forwardmost end for engaging the rocks and lifting them onto the picker grate. A conventional sweeping reel sweeps the rocks to a hopper. The forward end of each of the grate bars includes a portion consisting of a vertical plate parallel to the direction of movement together with a rotating rod which extends across the full width of the picker and is supported by the cup-shaped forward ends of the grate bars. The rod improves the rock picking action and also allows the clearing of trash between the rod and the vertical plate portions exposed at the front of the grate bars. A second embodiment includes a further rod positioned with a trip mechanism forwardly and downwardly of the first rod.
