236 through cable 237 so that pins 236 may be disengaged so that lever 230 may rotate about lever rotation axis 50. A perceived benefit of the present embodiment is that a user may use a single hand, or two hands, to actuate cable 237 and lever 230.

In yet a further embodiment, lever 230 may contain an electric motor operably coupled to lever 230 about lever rotation axis 50 such that lever 230 would rotate in response to the operation of the electric motor. The electric motor may be any suitable electric motor, such as a stepper motor, a servo motor, a direct drive motor, or any type of brushless or brushed motor. It is also contemplated that a mechanical linkage may be utilized that is connected to any other type of electric motor, such as a linear motor. A motor may be operated via a control panel located on plow assembly 100, or may further be controlled by a remote, a mobile device, a user interface within vehicle 10, or by a plurality of other inputs such as knobs, sliders, switches, etc.

Turning now to FIG. 7, the adjustment features of plow system 100 will be explained in greater detail. Illustratively, the adjustment features of plow system 100 allow plow subframe 200 to be adjusted vertically relative to vehicle subframe 300. In this way, the vertical height of blade 102 is adjusted allowing vehicle 10, or ground engaging members 14, to be various heights and still work with plow system 100. Illustratively, adjustment of plow system 100 is achieved through the use of a plurality of adjustment apertures configured to cooperate with each other. In the present invention, a first adjustment aperture 250 cooperates with one of a plurality of second adjustment apertures 251 including a second upper adjustment aperture 251A, a second middle adjustment aperture 251B, and a second lower adjustment aperture 251C. Similarly, a third adjustment aperture 252 is configured to cooperate with one of a plurality of fourth adjustment apertures 253 including a fourth upper adjustment aperture 253A, a fourth middle adjustment aperture 253B, and a fourth lower adjustment aperture 253C. Similarly, a plurality of fifth adjustment apertures 254, including a fifth upper adjustment aperture 254A, a fifth middle adjustment aperture 254B, and a fifth lower adjustment aperture 254C, are each configured to cooperate in turn with a sixth adjustment aperture 255.

In an exemplary embodiment, first adjustment aperture 250 is positioned on small mating brackets 214, third adjustment aperture 252 and fifth adjustment apertures 254 are positioned on large mating brackets 212. Further, second adjustment apertures 251, fourth adjustment apertures 253, and sixth adjustment aperture 255 are all located on main mounting plates 220. As can be seen in FIG. 7, the various adjustment apertures are vertically spaced from each other. Illustratively, second lower adjustment aperture 251C is located vertically lower than second middle adjustment aperture 251B which is located vertically lower than second upper adjustment aperture 251A. Similarly, fourth lower adjustment aperture 253C is located vertically lower than fourth middle adjustment aperture 253B which is located vertically lower than fourth upper adjustment aperture 253A. Similarly, fifth lower adjustment aperture 254C is located vertically lower than fifth middle adjustment aperture 254B which is located vertically lower than fifth upper adjustment aperture 254A. As can be best seen in FIG. 8, main frame 210 is angled forward and downwardly.

Demonstrably, the three sets of adjustment apertures, namely, second adjustment apertures 251, fourth adjustment apertures 253, and sixth adjustment aperture 255 align with corresponding adjustment apertures including first adjustment aperture 250, third adjustment aperture 252, and fifth adjustment apertures 254. The adjustment apertures are aligned such that three fasteners are used in each adjustment position, and in an exemplary embodiment there are three adjustment positions corresponding to a first or lowest adjustment position of blade 102, a second or intermediate adjustment position of blade 102, and a third or highest adjustment position of blade 102. In this way, when plow system 100 is adjusted, height of blade 102 is adjusted relative to the ground.

In a first or lowest adjustment position, blade 102 will be located in the lowest position and third fastener 215 is positioned in first adjustment aperture 250 and corresponding second lower adjustment aperture 251C, first fastener 213A is positioned in third adjustment aperture 252 and corresponding fourth lower adjustment aperture 253C and second fastener 213B is positioned in fifth upper adjustment aperture 254A and corresponding sixth adjustment aperture 255.

In a second or intermediate adjustment position, blade 102 will be located in a generally middle position and third fastener 215 is positioned in first adjustment aperture 250 and corresponding second middle adjustment aperture 251B, and first fastener 213A is positioned in third adjustment aperture 252 and corresponding fourth middle adjustment aperture 253B and second fastener 213B is positioned in fifth middle adjustment aperture 254B and corresponding sixth adjustment aperture 255.

In a third or highest adjustment position, blade 102 will be located in a highest position and third fastener 215 is positioned in first adjustment aperture 250 and corresponding second upper adjustment aperture 251A, and first fastener 213A is positioned in third adjustment aperture 252 and corresponding fourth upper adjustment aperture 253A and second fastener 213B is positioned in fifth lower adjustment aperture 254C and corresponding sixth adjustment aperture 255.

As can be seen in FIG. 8, the illustrated embodiment has three discrete positions. It should be understood that while this is an exemplary embodiment, any number of discrete positions may be achieved through the use of additional adjustment apertures vertically spaced from the current adjustment apertures.

In a further embodiment, it is conceived that main mounting plates 220 and large mating brackets 212 may comprise channels that replace the plurality of adjustment apertures disclosed herein, including second adjustment apertures 251, fourth adjustment apertures 253, and fifth adjustment apertures 254. In this way, adjustment may be infinite between an upper end and lower end of the described channels, providing additional adjustability for the position of blade 102. In an embodiment comprising channels, a locking slider may be used to effectively move plow subframe 200 relative to vehicle subframe 300.

In yet another embodiment, main mounting plates 220 may be inverted (not shown) so that a plurality of additional heights of plow system 100 might be achieved.
