Specifications include, but are not limited to: 11-FOOT HYDRAULICALLY REVERSIBLE, STRAIGHT MOLDBOARD SNOW PLOW WITH INTEGRAL SNOW SHIELD: 1. SWIVEL PLATE ASSEMBLY: A. Hitch pin mounting ears must be on 33-1/2 inch centers with each ear being 1-inch thick.; B. Holes in the mounting ears must be 1-9/32 inch positioned as per the prototype.; C. Mounting ears must be welded to a 7-inch MC (Ship & Car) channel weighing 22.7- pounds per foot. This channel will attach to and swivel against a 1-inch x 6-inch x 33- inch swivel plate. No exceptions. Swivel plate corners may be rounded.; 2. REVERSING A-FRAME ASSEMBLY: A. Reversing A-frame must consist of a 1-inch x 6-inch x 33-inch flat steel bar “swivel plate” with two 4-inch MC (ship & car) channels welded to it that extend forward and angle inward to a point for two 1-inch x 4-inch x 8-inch mounting plates.; B. Mounting plates must have a 1-9/32 inch holes centered and punched.; C. There must be a reversing stop plate welded to the swivel plate and the 4-inch channels that sandwiches the reversing circle flange. ; 3. CIRCLE REVERSING FRAME AND PUSH BEAM ASSEMBLY: Circle reversing frame must be a semicircle with two stiffeners to help reinforce it. Semicircle will attach to a 4-inch square tube or “push beam” that will have attachment points for the reversing A-frame pivot and moldboard mounting pivot ears. A. Semicircle must be made from 4-inch x 4-inch x ¾-inch angle iron with two like angle iron stiffeners. Semicircle and stiffeners must be welded to the top side of a 7-foot long 1/2-inch wall x 4-inch square steel tube or “push beam”. Tube must be one continuous piece (2-piece tube weldment is unacceptable).; B. There must be two triangular gussets 3/4-inch x 4-inch x 4-inch, welded to the underside of the semicircle. Gussets must be attached to the vertical side of the 4-inch square tubing to reinforce the semicircle attachment.; C. Semicircle must have welded stops appropriate for continuous plowing set at 30- degree plow positions, left and right.; 4. LEVEL LIFT SYSTEM: Plow must be equipped with a single-point pick, level lift system that will allow the plow to stay level with the ground regardless of the moldboard position. Lift system must use two 3/8-inch Grade-80 chains. One end of each chain must be connected either right or left of center to the 4-inch push beam with a 7/16-inch 2-ton galvanized shackle. The remaining end of each chain must connect to a single 1/2-inch, Grade-70 Transport chain using a 1/2- inch, 3-ton galvanized shackle as per the prototype (see “Figure-2”).; 5. MOLDBOARD: A. Moldboard must be a “C” shaped design, fabricated from 7-gauge, abrasion resistant rolled steel, (“break press” formed moldboards will not be acceptable).; B. Integral shield, moldboard must have an integral shield which will constitute the moldboard face extending 12 to 19-inches forward of the cutting edge at a consistent radius. (see “Figure-1”); C. Moldboard radius and integral shield must be sufficient to afford protection from snow and spray carrying onto truck hood and windshield.
