What goes wrong on soft ground
Soft ground punishes the edge and the surface at the same time.
- Digging. A low edge cuts into gravel or turf and pushes it into the pile, which is then spread back onto the road.
- Gouging. A hard edge tears turf and leaves ruts that outlast the snow.
- Stones. Gravel thrown ahead of the plow damages property as well as edges.
- Edge wear. Grit in the pile abrades the edge and hardware faster than snow does.
Adjustments
| Item | What to try |
|---|---|
| Shoes | Fit or set them so the edge stays slightly above the surface |
| Edge height | Plow with the edge skimming the snow, not scraping the ground |
| Speed | Slow, to reduce throw and digging |
| Angle | Push snow toward a safe storage area, away from garden beds and turf edges |
| Edge type | A flexible or poly edge can be gentler on soft surfaces; test before relying on it |
Safe routine
Soft ground rewards walking the area before driving it.
- Walk the area first and mark soft spots, turf edges and stones.
- Set the shoes and make the first pass slowly.
- Look back after the first pass and adjust if the surface was disturbed.
- Accept a thin snow layer where the ground is soft; it usually melts.
After the shift
The post-shift check is where gravel damage is found before it spreads.
- Check the edge and shoes for gravel damage and wear.
- Wash grit off hardware.
- Note any damage to the surface and the cause.
When to wait
If the snow is light and the ground soft, consider waiting for the surface to freeze or for the snow to melt, with the client’s agreement.
Site map idea
Draw a rough map of each soft-ground site showing gravel edges, turf, drains and stones, and mark where the plow should not go. Give the map to every driver who works the site. Update it after the first season, since you will learn where the ground stays soft and where it firms up, and the map becomes a simple way to hand the site to a new driver.
Boundary: no measurements are claimed. Adjust to your plow, site and client agreements.
