Abstract: A down pressure plow system with a float function is disclosed for use in a vehicle. The plow system includes a plow frame assembly and a plow blade carried by the plow blade assembly. An actuator is configured to move the plow blade up and down. A down pressure linkage is coupled to the plow frame assembly. The down pressure linkage applies a downward force to the plow blade upon actuating the actuator to move the plow blade and simultaneously allows the plow blade to move upward upon an upward force being applied to the plow blade.
