The short answer
They solve opposite problems. Buy a grinder when the stump has to disappear in place and you cannot leave spoil. Buy a cutter when you are already extracting stumps and the cost you are fighting is transport and processing volume. Most buyers who ask this question want a grinder.
Stump grinder
Destroys the stump and root plate below grade, in the ground
Choose it when
- The stump must be gone and the ground reinstated
- You are working urban sites where spoil cannot be left or carted
- Stump counts are high and you are pricing per stump
- Carrier is between 1.5 and 30 tonnes
Stump cutter
Splits and sizes a stump that has already been extracted
Choose it when
- Stumps are being pulled anyway as part of clearing
- Disposal volume, not removal, is the cost you are fighting
- Material is going to biomass or chip and needs sizing first
- Carrier is between 11.5 and 28 tonnes
Side by side
| Criterion | Stump grinder | Stump cutter |
|---|---|---|
| Where it works | In the ground, on the stump in place | On the surface, after extraction |
| What it leaves | Coarse chip, no spoil heap, no stump to move | Split stump sections plus the original excavation spoil |
| Carrier range | 1.5–30 t | 11.5–28 t |
| Circuit | Hammer line plus case drain | Hammer line plus case drain |
| Urban and near-asset work | Strong — nothing to cart away | Weak — you still have to extract first |
| Biomass and chip supply | Produces chip directly, but fines and soil contamination | Produces clean, sized material for processing |
| Dominant running cost | Teeth and tips, heavily ground-condition dependent | Blade and jaw rebuild, periodic rather than constant |
| The metric that matters | Cost per stump | Cost per tonne processed |
Shaded cell is the stronger side on that criterion
When the answer is both
Land clearing contractors running volume often end up with both: the grinder for finished sites and anything near assets, the cutter sitting on the second machine at the stockpile, sizing what the excavator pulls.
Questions that follow
01Can a stump cutter remove a stump from the ground?
No. A cutter works on a stump that is already out. Removal in place requires a grinder, or an excavator and a lot of digging.
02Do I need both if I already have a grinder?
Usually not. Buy a cutter when disposal volume is your cost, and a grinder when stump removal in place is your scope.
03Which is cheaper to run?
It depends entirely on ground. Grinder teeth in stony or sandy soil are a monthly line item; cutter blades are a periodic rebuild. Compare on cost per stump and cost per tonne rather than on purchase price.
