ABSTRACT:
A container for material such as fertilizer or seeds which delivers same to an underlying distributing device is mounted on a tractor so that the weight of the container and associated equipment is indicated to the operator of the tractor whereby the amount of material remaining in the container is specifically indicated. The weighing apparatus includes a spring, pointer and scale incorporated in the supporting structure extending from the tractor for the container and associated equipment and the pointer and scale may be interconnected to the spring and mounted on the tractor for the convenience of the operator. In one embodiment the spring is a tension spring at the top of the supporting structure and in another embodiment it is a compression spring near the bottom of the supporting structure. Instead of a spring, the weight may be indicated by hydraulic pressure in a hydraulic system for the supporting structure. Such pressure may be used to control a dosing mechanism in the distributing device via a computer to meter a given quantity of material based on the tractor's velocity and the quantity of material to be uniformly spread over a given area of field. The material can be a liquid and mounted on a frame having supporting wheels with information as to the weight of the container being conveyed by a hydraulic piston and cylinder assembly which is situated between the container and the mounting for the wheels.
