Abstract
A snowplow assembly includes an adjustment mechanism for use in adjusting the position of a snowplow frame member on a lift frame member into at least two positions: (1) a first position where the snowplow frame member is on the bottom portion of the lift frame member, the snowplow is positioned to plow snow, and the snowplow operation axis is substantially parallel to a ground surface; and, (2) a second position where the snowplow frame member is on the top portion of the lift frame member and the snowplow operation axis is at an angle A1 that is between 10° and 90° with respect to the ground surface.
Claims26
A method of adjusting a snowplow comprising the steps of:
- (a) providing a snowplow assembly comprising:
- (1) a support frame for use in connecting the snowplow assembly to an associated vehicle;
- (2) at least one lift frame member having a top portion and a bottom portion operatively connected to the support frame;
- (3) at least one snowplow frame member that engages the lift frame member;
- (4) a snowplow operatively connected to the snowplow frame member and having a snowplow operation axis;
- and, (5) an adjustment mechanism for use in adjusting the position of the snowplow frame member on the lift frame member;
- (b) lowering the snowplow frame member to the bottom portion of the lift frame member where the snowplow is positioned to plow snow and the snowplow operation axis is substantially parallel to a ground surface;
- (c) raising the snowplow frame member to the top portion of the lift frame member;
- and,
- (d) pivoting the snowplow frame member on the top portion of the lift frame member where the snowplow operation axis is at an angle A1 that is between 10° and 90° with respect to the ground surface.

- (b) connecting the snowplow assembly to a vehicle having a first head light providing a first headlight beam;
- (c) lowering the snowplow frame member to a first position where the snowplow is positioned to plow snow;
- (d) raising the snowplow frame member to a second position where the snowplow substantially interferes with the first headlight beam;
- and,
- (e) after step (d), further raising at least a portion of the snowplow frame member to a third position where the snowplow does not substantially interfere with the first headlight beam.
