Plowing Compacted Wind Drifts: Technique That Protects the Edge

Questions crews ask

How do we approach a hard drift?

Slowly, in a straight line, with the blade angled to cast snow off the road and the truck set up for traction. Test the drift with the edge at low speed before committing.

Is it better to take it in one pass or several?

Several passes in layers are usually better than one heavy pass. Take off the top, then go deeper. A single full-depth hit can stall the truck, bend the edge or damage the plow.

What about speed?

Enough to keep momentum, but not so much that the edge strikes the drift at high energy. Drivers who learn the feel of a drift make fewer costly mistakes.

What can hide in a drift?

Stranded vehicles, fence posts, signs, rocks and curbs. Scout on foot or by other means when you can, and approach with care when you cannot.

When should we use other equipment?

If the drift is too hard or deep for the plow, consider a loader, a blower or a bigger unit. Forcing it can damage the edge, the plow and the truck.

Which edge setup helps?

That depends on your equipment and surface. A robust edge in good condition helps, and one that is already worn will chip. Check the edge before the run.

Checklist

Wind drifts are harder than the snow around them, so the edge meets the worst material first.

1. Inspect the edge, shoes and mounting before the run.
2. Look at the drift and the road beyond it.
3. Approach at low speed and test.
4. Take the drift in layers.
5. Stop if anything unexpected appears.
6. Inspect the edge afterwards and record any damage.

Teaching new drivers

Pair new drivers with an experienced one for the first drifts of the season, and have them describe what they feel. Coaching the feel of a drift, and when to stop, is worth more than any rule about speed.

Boundary: No speeds, forces or snow-strength values are given; follow your agency’s procedures and the plow maker’s limits.
