摘要：
A seed cart includes first and second mating frames. The hopper is mounted on the first frame for holding seed and has an outlet to discharge the seed. A conveyor is mounted on the second frame for movement between seed loading and unloading positions. A plurality of cylinders with extendible and retractable arms control the desired position of the conveyor. A plurality of load cells are mounted on the second frame and support the first frame. The weigh scales weigh the first frame, the hopper, and the seed in the hopper, without weighing the conveyor. Therefore, an accurate amount of seed can be dispensed from the hopper via the conveyor. Wheels and a hitch tongue can be detachably mounted on the second frame to convert the cart from a stationary unit to a mobile unit.
