A crop harvesting machine for tomatoes, or the like, which lifts plants and fruit from ground level for transport upon one or more endless conveyors having spaced, parallel links. The invention resides in a system for keeping the conveyor links free from rocks, chunks of dirt, mud, and other foreign matter. The basic element is a cleanout device which is rotatably mounted adjacent one or more of the conveyors and has radially disposed members which extend through the spaces between the links as the chain is advanced and the device is rotated. An oscillating arm may also be provided in conjunction with one or more of the conveyors to impart a shaking movement, thereby aiding in dislodging foreign material from the space between the links.
