6.4 mm (1/4-inch) vertical side plates, conforming to the outside radius of the drum flanges.

Six bars, nominal 9.5 mm (3/8 inch) by 32 mm (1-1/4 inches) shall be welded to the vertical side plates. Three bars shall be on the top, spaced equally on the top radius, and three bars shall be on the bottom, spaced equally on the bottom radius. The vertical distance between the vertical aide plates and the drum flanges shall be not more than half the specified cable diameter.

3.6.5 Front bumper with a front winch. When a front mounted winch is specified, the front bumper shall be forward of the winch. The bumper shall be either a channel or a pipe type. When the pipe type, the nominal diameter shall be not less than three inches, and the wall thickness shall be not less than that specified in Schedule 40 of ASTM A53.

Not less than 6.4 mm (1/4 inch) nor not more than 9.5 mm (3/8 inch) of space shall be left between the front bumper and the guard and the guard and the cab. Rubber flaps may be employed to achieve these dimensions and shall be employed when required by tilting hood/fender vehicles for unrestricted tilting. The step plate shall support 14.4 kilo newtons on any square meter (300 pounds on any square foot) of area. The step plate shall not deflect more than 3.2 mm (1/8 inch) under such loads.

3.7 Snowplow. When specified (see 6.2), the vehicle shall be equipped with a hydraulic or electro-hydraulic snowplow. The snowplow shall be complete with a truck mounted hitch, push frame assembly, moldboard, snow deflector, tripping device, hydraulic lifting mechanism, snow deflector and all other necessary mounting and operating apparatus.

reversible type. When specified (see 6.2), the plow shall be of the one-way type with a cut of not less than 2440 mm (96 inches) at a blade angle of 35 degrees plus 2 degrees, minus 0 degrees. The one-way snowplow shall have a minimum of two angle adjustments. Raising either type of plow, at all angles the plow is capable of attaining, shall not interfere with any part of the truck.

3.7.2 Moldboard, reversible plow. The moldboard of the reversible type snowplow, exclusive of the snow deflector, shall have a vertical height of not leas than 810 mm (32 inches). The moldboard shall be capable of clearing a path not less than 2620 mm (8 feet 7 inches) wide at a blade angle of 30 degrees, plus 2 degrees, minus 0 degrees. The actual length of the moldboard shall be not less than 3050 mm (10 feet).
