  • Accident prevention device for rotary snow-plow
    Patent number: 4996783
    Abstract: An accident preventing arrangement for rotary snowplows includes a front safety bar in front of the rotating blades. When lowered, the safety bar actuates switches which, in turn, not only disengage a clutch for a drive shaft which rotates the blades, but also instantaneously brakes the blades. Another switch located in a driver's cab performs the same functions by manual operator control.
