FEATURES:

  • Heavy-duty double A-frame.
  • Quick coupler plow units attach to push plate with 2" diameter pivot bolt allowing desired snow plow oscillation for cleaner plowing.
  • Four rolled, heavy channel iron ribs provide maximum rollboard rigidity. Horizontal channel braces reinforce transverse stability.
  • Moldboard may be tilted forward or back depending on snow and road conditions.
  • Nitrided cylinders for increased corrosion resistance.
  • Bottom support structure is constructed of 4" x 4" x 3/4" A-36MOD angle iron reinforced between bolt holes. Discharge end is reinforced with an additional 1/2" x 7" 1045 steel plate.
  • Heavy-duty tubular push frame distributes plowing stresses across full length of moldboard.
  • Two heavy-duty single-acting reversing cylinders for quick control with hydraulic cushion valve for circuit protection.
  • Nitrided cylinders for increased corrosion resistance.
  • 3/8" landslide plate has renewable nose.
  • Standard screw-adjustable mushroom shoes.

9' 10" (3 m)		 The power reversible one way snow plow shall be the latest design and model. Materials used shall be top quality as specified to insure uniformity.

DIMENSIONS: Cutting width or space cleared by the snow plow shall be not less than _____ at 0 degrees and _____ at 35 degrees left or right. Overall width shall be not greater than _____ Moldboard height at nose shall be not less than 30". Moldboard height at discharge shall be not less than 58". 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 Height, nose 30" (.762m) MOLDBOARD: 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 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.

 MOUNT ASSEMBLY: 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.
