Created by Dennis Whalen, the scale was produced by Powermation in St. Paul, Minn.
The idea for the scale “came to me when I was working for a local farmer,” Whalen says. “I was loading the trailer with a grain cart and wishing I knew how heavy my load was. I thought it would be great to have a scale mounted under the trailer with a digital display visible from the combine or tractor cab. This scale would take the guess work out of loading.”
Whalen says his scale will record the gross weight of a tractor-trailer combination up to 99,999 lbs. on fixed axle air-ride trailers, and should help eliminate the risk of overloading a trailer.
