In combination a mount frame adapted to be attached to a vehicle and a snowplow assembly. The mount frame comprises a pair of detachable receivers which receive a pair of horns extending rearwardly from the snowplow assembly. The snowplow assembly comprises an A-frame, a trunnion and a lift frame. A blade is attached to the front of the A-frame. A pair of spaced stand assemblies, each including a latching mechanism, support the snowplow assembly when the mount frame is separated from the snowplow assembly. The latching mechanisms secure the snowplow assembly to the mount frame.

A vehicle mounted accessory unit assembly is provided that is removably mountable to a vehicle, the accessory assembly including a support frame having a first and second portion that are connected at a pivot point, with the pivot point enabling forces to be directed in such a way as to minimize the stresses on the vehicle to which the accessory unit assembly is attached. The accessory unit assembly further includes a wheel assembly to further minimize the stresses on the vehicle. The wheel assembly preferably includes a ground engaging wheel, a mounting member, a spring assembly and a dampener. A steering dampener is also utilized.

A snowplow (20) adapted for being attached to or detached from a vehicle (22) having a frame (24). The snowplow includes a mount frame (26) for connection to the vehicle frame, a support frame (32), a lift assembly (38) and a blade assembly. The blade assembly of the invention includes a blade (30), a blade cutting edge (31) and a wheel support assembly (56). The support frame includes a forward end (33) for supporting the blade and a rearward end (36) for connection to the vehicle. When detached from the vehicle as a single unit, the resultant weight on the rearward end of the support frame may be supported on a ground surface (46) by a jack stand (48). The wheel support assembly includes a yoke assembly (60) having a pair of sides (62) for supporting a wheel (57), a biased spring 80 mounted onto a stud (76) for allowing the yoke assembly to rotate from an upward inoperative position to a downward load support position, a handle (64), a support plate (65) and a bracket assembly (90) for mounting the wheel assembly to the snowplow. The wheel assembly is rotatable between the inoperative position and the load supporting position and is in the load supporting position when the snowplow is detached from the vehicle. An advantage of this invention is that nearly all of the weight of the snowplow is supported by the wheel support assembly when the snowplow is detached from the vehicle.

The snowplow includes a mount frame (26) for connection to the vehicle frame, a support frame (32), a lift assembly (38) and a blade assembly. The blade assembly includes a blade (30), a blade cutting edge (31) and a wheel support assembly (56). The support frame includes a forward end (33) for supporting the blade and a rearward end (36) for connection to the vehicle. When detached from the vehicle as a single unit, the resultant weight on the rearward end of the support frame is supported on a ground surface (46) by a jack stand (48). The wheel support assembly is mounted adjacent to or slightly ahead of a center of gravity (58). The wheel support assembly includes a yoke assembly (60) having a pair of sides (62) for supporting a wheel (57), a biased spring (80) mounted onto a stud (76) for allowing the yoke assembly to rotate from an upward inoperative position to a downward load support position, a handle (64), a support plate (65) and a bracket assembly (90) for mounting the wheel assembly to the snowplow. An advantage of this invention is that nearly all of the weight of the snowplow is supported by the wheel support assembly when the snowplow is detached from the vehicle. This allows even the smallest of operators to be able to easily maneuver the snowplow in any direction around a storage area with no additional assistance being required to attach the snowplow to the vehicle.

A dispenser apparatus for spreading granular material such as salt or sand. The dispenser apparatus includes a hopper that funnels the granular material down to a discharge spout for discharge onto a rotating spreader to broadcast the material onto a roadway. The hopper defines a generally downwardly converging chute that has intermittent radially enlarged sections to minimize 'bridging' of the granular material within the hopper. An agitator arrangement provided in the hopper also assists in eliminating any blockage near the base of the hopper.

The invention contemplates an automatic headlamp switching system that enables an operator to use an existing vehicle headlamp switch to operate a secondary light source on an accessory unit attached to a vehicle. The vehicle includes a primary circuit having a primary light source, an energy source, and a parking/headlamp switch for connecting the energy source and the primary light source so that the primary light source is selectively energizable. A secondary circuit includes the secondary light source. A pair of relays are connectable in circuit with the primary and secondary light sources. When the accessory unit is electrically connected to the vehicle, the relays are operative to interrupt the primary circuit from the energy source to the primary light source and simultaneously complete the secondary circuit from the energy source to the secondary light source.

A log splitter comprising a frame generally in the shape of a right triangle having three legs lying in a vertical plane. The frame includes an elongated horizontal member forming the first leg of the right triangle, the elongated horizontal member including a first end, a second end, and an upper surface adapted to support a log. The frame also includes an elongated second member forming the hypotenuse of the right triangle and being positioned below the elongated horizontal member, the elongated second member including a first end and a second end. The first end of the elongated second member is fixedly attached to the first end of the elongated horizontal member. The second end of the elongated second member is adapted to rest on a supporting surface. The frame further includes a wedge member including upper and lower portions, the upper portion of the wedge member extending upwardly from the second end of the elongated horizontal member and having a splitting edge, and the lower portion of the wedge member forming the third leg of the right triangle and being secured to the second end of the elongated horizontal member and to the second end of the elongated second member and supporting the second ends in rigidly spaced apart relation. The log splitter also includes means for supporting the first end of the elongated horizontal member and the first end of the elongated second member above the supporting surface and ram means for pushing a log along the upper surface of the elongated horizontal member toward the splitting edge of the wedge member for splitting the log with the wedge member.
