International ClassB60P 001/36AbstractA portable grain cart that has independently operated, endless, rubber belted conveyors for moving material out of the hopper and then discharging the material into a truck or other transport or storage facility. A first rubber belted conveyor is mounted inside of the hopper to pick up the material from the hopper and then discharge the material outside the cart onto a second conveyor which then moves the material into the truck. The outside or discharge conveyor is pivotally mounted so that it can be swung to a number of positions, including a storage position, and it also can be elevated to different heights depending upon the truck or storage facility into which the material is to be discharged.Other References
