1690088 - 46" Angle Dozer
To mount this blade on 700 series tractors requires 1690089 hitch. This blade and hitch combination is then equivalent to the old 1600257 46" blade. The blade is the spring trip type so that it will protect both the tractor and operator from sudden jolts. Wheel weight and possibly chains are recommended depending on conditions.
