Overall width shall be not greater than _____

Overall height shall be not less than 43".

Cutting edge shall be one (1) 5/8" x 6" x _____ft. Cutting edge shall be AASHO punched.

Total weight shall not be less than ______ pounds

Moldboard shall be smooth rolled design. The roll radius of the moldboard shall be 18". Moldboard shall be constructed of not less than 10 ga. high strength carbon steel, A607 Grade 50 or equal. Mild steel is not acceptable. Moldboard shall be reinforced with not less than ten (10) vertical ribs or five (5) rolled 4" channel iron ribs. The vertical braces shall be additionally reinforced with horizontal cross members of not less than 4" channel iron. Top edge of the moldboard shall be double flanged or reinforced with a minimum 2" x 2" x 3/16" A-36 angle iron. The bottom moldboard support structure or frog shall be a minimum 4" x 4" x 3/4" thick A-36 MOD angle iron boxed the entire distance between bolt holes for reinforcement. Moldboard shall have built in snow deflectors. The built-in snow deflectors shall extend approximately 12" beyond a vertical line drawn from the leading edge of the cutting edge when the attack angle of the cutting edge is at 35 degrees (measured from vertical).

Plow shall have variable moldboard pitch adjustment to allow the attack angle of the cutting edge to be changed from approximately 15 degrees to 35 degrees as measured back from a vertical line extending up from cutting edge.

OR

Plow moldboard and push frame shall be equipped with slotted trip assemblies that will permit the plow to slide up and away from road obstructions in order to mitigate impact shock and potential damage to the snow plow. The lower moldboard support shall have two (2) sets of trip slide receptors comprised of 3/4" steel plate with 1" steel spacers. The spring shall be minimum 11/16" wire diameter x 16" length 5160H spring steel. The rod shall be minimum 1-1/4" diameter cold-rolled steel with 1-3/4" slotted steel plate. The retainer nut shall incorporate a safety device preventing accidental nut rotation and to aid in retention of components in the event of failure. Note: not available on Model 310.

The reversible angle push frame shall be of heavy duty construction and shall be designed to distribute plowing stresses across the entire length of the lower moldboard angle. The push frame shall attach to the moldboard with no less than four (4) 1-1/4" diameter pins. The main components of the push frame shall be manufactured of 4" x 4" x 1/4" wall square tubing, Grade A-500B or better.

The reversible A-frame shall be of tubular construction, minimum 4" x 2" x 3/16", A-500B or better. The reversible A-frame shall straddle the push frame, that is it shall be doubled such as manufactured by Little Falls Machine, Inc. and shall support the pivot pin at the top and the bottom for maximum strength. The pivot pin shall be a minimum 1-1/2" diameter.

Power reversible snow plow shall incorporate a free floating oscillating feature to allow the plow to follow the changing road contours. This feature shall not be sacrificed if plow is equipped with any quick coupler.

Plow shall be equipped with two (2) compression spring loaded pitch adjustment bars to allow the one way snow plow to "trip" over obstructions and return to the normal plowing position without having to manually reset the tripping device. Each spring shall be 9/16" diameter with a solid load rate of 1,644 lbs or a combined rate of 3,288 pounds.

Power reversible snow plow shall be equipped with two (2) shoes, 1-1/2" thick x 11" diameter, Austempered Ductile Iron (A.D.I.) or equal. Shoes shall be adjustable without the use of tools.

Curb shoes at one or both ends.

Slotted trip assemblies.
