Abstract
A safety system for a wireless snowplow controller makes the wireless controller safer and more effective. The system includes a vehicle, a snowplow, a wireless controller and a tether. The controller wirelessly sends one or more control signs to one or more control modules coupled to the vehicle and/or the snowplow. The control signals may be used to control operation of the snowplow. The controller may be configured such that it is only able to send control signals when it is connected, via the tether, to a power supply coupled to the vehicle.
