A measurement system used in conjunction with a conveyor includes a first sensor with a first transceiver and a second sensor with a second transceiver. The transceivers transmit a first light beam and a second light beam towards a movable portion of the conveyor. A control unit communicably coupled to the first sensor and the second sensor, wherein the control unit calculates a first distance between the first sensor and the movable portion based on the first sensor and a second distance between the second sensor and the movable portion based on the second sensor. The control unit determines a difference value between the first distance and the second distance; and stops the unloader in response to the difference value being above a predefined threshold value.

An extendable and retractable conveyor comprises a hopper for receiving agricultural product a housing having an inlet and an outlet that are separated by a fixed distance, the inlet being adjacent to the hopper for receiving the agricultural product from the hopper. The conveyor may include a belt conveyor disposed within the housing for conveying the agricultural product from the inlet to the outlet, the conveyor defining a direction of conveyance. The conveyor further includes a hood connected to the outlet for deflecting the agricultural product relative to the direction of conveyance. The conveyor further includes a movable spout that is slidably connected to the tube and disposed beneath the hood to receive the agricultural product from the hood, the movable spout being slidable in a direction parallel to the direction of conveyance to thereby extend or retract the conveyor.

A boom conveyor includes a boom that carries a conveyor, a support structure for the boom, a rear pivot joint that connects a rear end of the boom to the support structure, and a pivot drive that controls pivoting movement of the boom about the rear pivot joint. The boom conveyor apparatus includes an operator platform and an attachment mechanism at a front end of the boom whereby the operator platform may be attached to the boom or detached therefrom. The attachment mechanism includes a leveling mechanism that is configured to apply a leveling adjustment to the operator platform.
