Wing plow post

A wing plow post assembly comprising:

• an end plate perpendicularly secured to the end of the tube, the end plate comprising:
• an upper end and a lower end;
• at least two vertical edges;
• a longitudinal axis tilted at an angle of 5-20 degrees from vertical the end plate perpendicular to a forward direction of a vehicle to which the wing plow post is mounted;
• two side plates each secured to a separate vertical edge of the end plate;
• an upper connection arm pivotally secured to each side plate, the upper connection arm comprising two side links and a cylinder bushing and having a longitudinal axis;
• a lower connection arm pivotally secured to each side plate, the lower connection arm comprising two side links and having a longitudinal axis;
• wherein the upper connection arm longitudinal axis and the lower connection arm longitudinal axis are substantially perpendicular to a forward direction of a vehicle to which the wing plow post is mounted;
• a hydraulic cylinder having a lower end and an upper end, the lower end secured to the end plate and the upper end operably secured to the cylinder bushing;
• a front plate pivotally secured to the upper connection arm and pivotally secured to the lower connection arm;
• and
• a removable slab pin pivotally secured to the front plate.

A mount for a wing plow comprising:

• An end plate comprising two opposite edges and a longitudinal axis tilted at an angle of 5-20 degrees from vertical the end plate perpendicular to a forward direction of a vehicle to which the wing plow is mounted;
• two side plates, each side plate secured to an opposite edge of the end plate;
• an upper connection arm pivotally secured to each side plate, the upper connection arm comprising two side links and a cylinder connection means, each side link having a longitudinal axis;
• a lower connection arm pivotally secured to each side plate, the lower connection arm comprising two side links, each side link having a longitudinal axis;
• wherein the upper connection arm side link longitudinal axes and the lower connection arm side link longitudinal axes are substantially perpendicular to a forward direction of a vehicle to which the wing plow post is mounted;
• a hydraulic cylinder having a lower end and an upper end, the lower end secured to the end plate and the upper end secured to the cylinder connection means;
• means for connecting a slab to the upper connection arm and to the lower connection arm.
