24
ERDC/CRREL SR-02-1
WARNING!
Never put your head out of the window while plowing. Sudden stops or pro-
truding objects can cause serious injury or death.
WARNING!
To prevent damage to plow or HMMWV, flag or otherwise mark any known
obstructions that are hard to locate.
21. Before plowing snow, make yourself aware of any possible obstructions
hidden beneath the snow, such as bumper stops in parking lots, curbs, walkways,
sidewalks, shrubs, fencing, rocks, and other protruding objects. Make every
effort to become familiar with the area you may be called on to plow.
22. If at all possible, plow during the storm rather than let the snow
accumulate. As a general rule of thumb, plow before four inches of snow
accumulates.
23. When plowing staging areas, parking lots, or helipads, if you want to
stack snow, begin raising the blade as you come close to the stack. This will let
the blade ride up the stack.
WARNING!
If attempting to clear a helipad, be certain that the area is sufficiently large to
accommodate the largest helicopter with ample room to permit all clearances. Do
not stack snow high enough to endanger the helicopter blades.
24. Certain conditions require various skills and techniques to plow
successfully.
Hard-packed snow
Raise the disc shoes on the blade high enough so that the cutting
edge comes into direct contact with the pavement.
Use the lowest gear to place maximum force behind the cutting edge.
Angle the blade; it is more effective for removing hard-packed snow.
Deep snow
Raise the blade 34 inches and try shearing off top layers for the
initial pass.
Using only partial blade width, bite into the edges until the job is cut
down to size for full-blade plowing.
