All models are water and dust resistant, have been thoroughly tested in the harshest farm environments, and carry a three-year warranty.

Truck Scale

An on-farm or in-plant truck scale will save you money in several ways.  You can verify incoming delivery weights, pre-check load weights going out to the elevator, or check grain yields to compare the performance of different seeds, fields or fertilizers.  You will no longer have to worry about picking up a traffic ticket for an overloaded truck.

A truck scale WeighBar kit consists of four or eight WeighBars with cables and brackets.  (Indicators sold separately ).  Additional construction materials can be purchased locally.  A full checklist of materials needed own economical farm or plant weighing system is available at your request.
