The Fisher RD Series snow plow is perfect for owners of mid-size four-wheel drive trucks. The 7'6" blade is supported by eight vertical ribs and two cast iron shoes to resist damage to the blade while plowing. Controlled by the Fisher Fish-Stik control, the RD Series plow uses powerful Fisher-built hydraulics to quickly change from position to position. With the Minute Mount 2 Mounting System, the attachment of the plow to the plow truck takes less than a minute to do. Using the Fleet Flex electrical system, the controls used for the RD Series plow can be used for any other Fisher plow. An optional 3/8" X 6" high carbon steel cutting edge is available. Instantaneous "float" is available with the powerful chain lift system, meaning the blade is free to follow the contours of the plowing surface. The blade is designed with the Fisher trip-edge design which allows only the edge of the blade to trip when an obstacle is encountered, keeping the load of snow in front of the plow and protecting the blade and truck from damage due to obstacles. The Fisher RD Series is the ideal tool for personal use and for light commercial use with a half-ton truck.
