The more time road department crews spend mowing, the less time they have to complete other important road maintenance tasks. By controlling weeds with selective herbicide treatments, we can take workers off of the tractors so they can complete other vital roadway maintenance tasks. With an herbicide program, we can cover a 400 mile county in about a weeks’ time using just one spray truck. You would need 10+ tractors and mowers, plus trucks with flagmen, to cover a similar are in that time frame.
Mowers travel at 3 to 5 miles per hour and are constantly moving around signs, culverts, bridges and other obstacles that puts them right in line with traveling motorist. Roadside spray trucks travel between 10 and 15mph in the same direction as traffic making encounters with motorist much less dangerous.
