  • Patent number: 9510510
    Abstract: A material collection system sensor includes a paddle pivotably mounted to a tunnel on a collection container floor. The forward end of the paddle is adjacent a front of the collection container and the rearward end is adjacent a rear of the collection container. A switch mounted to the tunnel under the paddle has an actuator extending above the tunnel that is actuatable by downward pivotal movement of the paddle. A sensitivity adjuster attached to the tunnel under the paddle has a sensitivity adjustment knob outside the collection container which compresses or relaxes a spring extending upwardly against the paddle.
