Stump Grinding in Cokato and Central Minnesota

Stump grinding around Cokato and the surrounding towns is usually the last step of a removal, though we do plenty of stumps left behind by somebody else years ago. The machine takes the stump down below grade so you can run a mower over it, put sod back, or plant something new in roughly the same area.

How far down it goes

Standard practice is four to six inches below grade, which is enough to get soil and grass over it and mow without hitting anything. If you are planting a new tree in the same spot or laying a patio, it needs to go deeper, closer to a foot or more, and the surface roots radiating out from the stump need grinding too. Tell us what the spot is going to become and we will grind it to suit rather than to a default.

Utilities get located first

Stumps sit right where irrigation lines, invisible fence, low-voltage lighting and sometimes gas and electric services run. A grinder wheel does not care what it finds. Minnesota's Gopher State One Call handles public utility locates and it is free, and we allow the required notice before grinding. Private lines are the ones that catch people out, because the locate service does not mark them. If you have irrigation, dog fence or landscape lighting anywhere near the stump, tell us where before we start.

What you are left with

Grinding produces a surprising volume of chips, considerably more than the stump appeared to contain, because the material fluffs up as it is cut. By default we rake the chips back into the hole and mound them slightly, because they will settle over the following months. If you want the chips gone, we can haul them and bring in soil instead, which is the right approach if you are laying sod or planting straight away. Chips are fine as mulch elsewhere on the property but they are not good soil for planting into.

Roots and the ones we leave

Grinding takes the stump and the surface roots near it. It does not take the entire root system, and it does not need to: the remaining roots decay in the ground over several years without causing problems. The exception is where roots are actively lifting a walkway or pushing into a foundation, which is a separate job and worth pointing out during the estimate.

What you get

  • Ground four to six inches below grade as standard, deeper on request
  • Deeper grinding and root work where you are replanting or paving
  • Utility locates arranged before the wheel touches anything
  • Chips raked back or hauled off, whichever you want
  • Done at the same visit as a removal so the machine only travels once
  • Old stumps left behind by somebody else are welcome work

How the job runs

  1. Locate Public utilities located, and we ask you about irrigation, dog fence and lighting.
  2. Clear Rocks and debris pulled away from the stump so nothing gets thrown by the wheel.
  3. Grind Down below grade, plus the surface roots, to whatever depth the new use needs.
  4. Finish Chips raked back and mounded, or hauled away and soil brought in.

What does stump grinding cost?

Stump grinding is usually priced on the diameter of the stump measured at ground level, plus the number of stumps and how easy they are to reach. Doing it at the same visit as the removal is cheaper than bringing the machine back, and doing several at once costs less per stump than doing one.

What moves the price:

  • Diameter of the stump measured across at ground level
  • How many stumps and how close together they are
  • Access, since a back yard with a narrow gate limits which machine can get in
  • How deep it needs to go, which depends on what is going in afterwards
  • Whether the chips stay or get hauled and replaced with soil
  • Rocks, gravel or old concrete in and around the stump

Stump Grinding questions

How deep do you grind a stump?

Four to six inches below grade is standard, which is enough to cover with soil and mow over. If you are planting a new tree in the same spot or laying a hard surface, we go deeper and take out more of the surface roots. Tell us the plan for the spot and we will match it.

Can I plant a new tree where the old one was?

Yes, with a couple of adjustments. Grind deeper than standard, get most of the chips out of the hole, and bring in soil to backfill. Planting straight into wood chips does not work well because they tie up nitrogen as they break down. Offsetting the new tree a few feet also helps.

Will the roots keep growing after grinding?

No. Once the stump is ground out the tree cannot produce leaves, so the root system has no way of feeding itself and it dies. A few species send up suckers from remaining roots for a season or two, and those stop once the reserves run out.

Do I need to mark anything before you come?

We arrange the public utility locate. What we need from you is the location of anything private, since those never get marked by the locate service: irrigation lines, invisible dog fence, landscape lighting cable and septic components are the usual ones.
