An old stump is a mower hazard, a tripping hazard, and a home for carpenter ants. Grinding is the fastest way to get rid of it. No digging, no chemicals, and the job usually takes minutes to an hour per stump.
How stump grinding works
A stump grinder uses a spinning wheel with carbide teeth to chew the stump and the top of the main roots into wood chips. The operator sweeps the wheel back and forth until the stump is below the soil surface. Compact grinders can fit through a typical backyard gate, and larger machines handle big stumps or many stumps on a lot.
How deep should a stump be ground?
- For lawn: a few inches below grade is usually enough to cover with topsoil and seed.
- For a new tree or shrub in the same spot: grind deeper and remove the chips, or plant slightly off-center.
- For a patio, walkway, or addition: tell the crew up front. You may need deeper grinding or full root excavation.
Ask what depth is included in the quote. It's the most common source of mismatched expectations.
What happens to the chips and the hole
Grinding leaves a mound of chips and soil roughly the size of the stump. Options are to rake it back into the hole (it settles as it decomposes), haul the chips away and backfill with loam, or keep the chips for mulch elsewhere. Wood chips mixed into soil tie up nitrogen for a while, so if you're seeding grass right away, swapping chips for topsoil gives better results.
Before the grinder shows up
- Mark irrigation lines, invisible dog fence wire, and landscape lighting near the stump.
- Know where your septic tank, leach field, and any buried utility lines are. Crews may call Dig Safe (811) before grinding near possible buried utilities.
- Note the approximate number and diameter of stumps. Photos with a tape measure help produce an accurate quote.
Note: Massachusetts open-burning rules specifically exclude stumps, so burning isn't an option for disposal. Grinding or hauling is.
Frequently asked questions
How much does stump grinding cost?
It depends mostly on stump diameter at ground level, the number of stumps, the wood type, and access for the machine. Multiple stumps on one visit usually cost less per stump. Send the count and approximate diameters for an accurate quote.
Will the roots keep growing after grinding?
Most species won't re-sprout once the stump is ground below grade. Some, such as certain maples, poplars, and sumac, can send up shoots from remaining roots for a season. Mowing or clipping those shoots generally ends it.
Is grinding better than pulling the stump out?
For most yards, yes. Excavating a stump with a machine tears up a much larger area and leaves a big hole. Full removal mostly makes sense where you're building or need the roots out completely.
Can a grinder get into a fenced backyard?
Usually. Compact stump grinders are built to fit through standard gates. Mention gate width when you request a quote.
Can I just burn the stump?
No. Massachusetts open-burning rules allow certain brush and forestry debris during the permitted season but specifically exclude stumps. Grinding is the practical option.
