What is a TowPlow?

The TowPlow is a steerable trailer-mounted plow that is pulled behind a tandem axle snowplow truck and is able to swing out to one side, which doubles the plow width of a tandem-axle snowplow truck. The TowPlow is equipped with a 26' moldboard and either a granular spreader or a tank for dispensing liquids for snow and ice control. The TowPlow has been used successfully in Missouri since 2005 and several others states have begun to evaluate the TowPlow.


  • Increased efficiency and production (One pass clearing, improved cycle times, wider clearing path)
  • Reduction in manpower and equipment
  • Environmental benefits from using less fuel
  • Safety improvements due to improved cycle times
  • Longer service life than snow plow trucks.
