MOUNT VERNON — The Knox County Highway Department has a new computerized system of applying salt to roads that promises to save the taxpayers substantial amounts of money over the snow season. Here is the way it works.
The computer is mounted in the cab of the truck and the driver dials in the amount of salt he wants to spread per mile. Depending on the conditions, the driver can set the computer from as low as 200 pounds of salt per mile to 600 pounds or more.
The computer controls a hydraulic system on the truck that runs an auger feeding salt to the spinner. Controlled by the computer the spinner spreads the salt on the road in the required amount.
