A common question — and a common mistake in both directions. The right depth depends on what you plan to do with the spot afterward.
The standard: 4–6 inches below grade
For most yards, grinding 4–6 inches below ground level is enough to get rid of the visible stump, plant grass, or lay sod over the spot without the stump showing through.
Go deeper (8–12 inches) if you're
- Replanting a tree in the same spot.
- Building, paving, or laying a foundation or footing over the area.
- Dealing with a species that suckers aggressively.
Why not just grind shallow?
Grinding too shallow leaves enough root mass for suckers to sprout and for surface roots to interfere with new sod or landscaping — the stump effectively "comes back." That's the single most common reason a DIY job disappoints.
But don't overdo it
Lowering the wheel too deep too fast strains the engine and causes stalls and kickback. And near a house, going deeper than necessary risks buried cables — read grinding a stump near a house or utilities before you dig in. Work in shallow passes and creep down to your target depth.
