  • Patent number: 6691435
    Abstract: A snow plow system for use with a skid steer loader includes a V-plow blade that is repositionable by a hydraulic actuator operated by pressurized hydraulic fluid supplied to the actuator from the auxiliary hydraulic output of the skid steer loader. A normally open valve diverts hydraulic fluid away from the actuator whenever the plow blade is not being repositioned, enabling the auxiliary hydraulic system to be maintained actuated. The valve is operated to a closed condition by a wireless remote control receiver which receives coded radio frequency signals transmitted by a wireless, portable, battery-powered transmitter locatable within or outside of a cab of the vehicle, or by a voice-actuated control. A mounting panel of the snow plow system includes an anti-slip surface, providing footing for an operator upon entering or exiting the cab of the vehicle.
