Stump grinding in Austin takes the stump out below ground level with a machine matched to the access. Our standard grind is four to six inches below grade, and deeper where something is going back in that spot. Where grinding is not the right answer we excavate the root ball whole or leave the stump in place, and we also grind surface roots, clean up behind the work, and put a new tree in the spot if that is what you want.
Grinding the Whole Stump
We keep three grinders so the machine can be matched to the site instead of the site being adapted to the machine. The 40 HP Bandit SG40 is the compact one, and it fits through most backyard gates while still cutting well below grade. The 75 HP Bandit SG75 is the large-stump machine, for trunks and root plates the smaller grinders would spend a day on. The 40 HP Top Notch .38 Special is self-powered and mounts on the attachment plate of our Giant G1200 tele-loader, which is the point of owning it: the loader’s boom and telescopic arm put a grinder into a raised bed set back from the travel path, the far side of a culvert, or a corner of a finished landscape that a walk-behind machine has no route into.
Our standard grind is four to six inches below grade. That is enough to put sod, soil, or mulch back over the spot and be done with it. We set the machine deeper when something is going into that location afterward, whether that is a new tree, a walk, a footing, or a bed that has to grade flat. Depth is a decision we make with you before we start, because it changes how much material comes out of the hole and what has to go back into it.
The work is performed to ANSI A300, the industry standard for tree care performance, and the site is run to ANSI Z133, the safety standard for arboricultural operations. A grinder throws material hard and fast, so the exclusion zone around the machine, the position of the operator, and the protection of everything downrange are part of the job rather than an afterthought.
Stump Grinding Alternatives
Grinding is the usual answer to a stump and it is not the only one. Which alternative fits comes down to what is going into that ground afterward, and whether the stump is in anyone’s way at all.
When the whole root mass has to come out rather than be ground down, we bring a Yanmar SV100 excavator with a log grapple and pull the root ball out whole, with a Giant G1200 loader or a Boxer 320 handling material behind it. That is the job when the ground itself needs to be clear: a foundation, a pool, a retaining wall, a utility run, or a regrade where the remaining roots would be in the way of the excavation that follows ours. It leaves a substantially larger hole than a grinder does, and that hole has to be backfilled, compacted where a structure is going in, and graded. When the excavation is prep for someone else’s work, we scope it against what their crew needs to find when they arrive.
The other alternative is leaving the stump where it stands, and on the right site that is a deliberate choice rather than an unfinished job. A stump in a back corner, inside a bed, or out on acreage is often in nobody’s way, and it will break down in place over years. What it means for the site is worth settling before the machines leave: the spot stays unavailable for planting, paving, or grading, and it has to be mowed and edged around. We will say so when we think grinding that particular stump is not buying you anything.
Grinding Surface Tree Roots
Surface root grinding takes down roots that have risen into the lawn, lifted a walk or a patio edge, or sit where a mower deck keeps catching them. We do it as its own service, and it does not require that the tree be coming out.
The judgment is which roots come off and how much of any one of them, and that decision belongs to an arborist standing at the tree rather than to the operator running the machine. Distance from the trunk, the size of the root, how many of them are in question, and what the tree has already been through all bear on what we are willing to cut. We will tell you plainly which roots we will take down, which ones we will not, and what a partial answer looks like when the full one is not something we would do to that tree. Root work follows ANSI A300 Part 8, the root management standard.
Clean Up from Stump Grinding
Most of the work on a finished landscape happens before the grinder starts. Gravel gets raked back and containerized for reuse, prized plants get dug or potted and set aside, landscape lighting and irrigation is identified, and containment barriers and tarps go up so the grindings end up where we can collect them rather than across a bed or a pool.
How much of that we do is yours to scope. At one end, you do the prep yourself and we show up, grind, and go. At the other, we salvage the landscape materials, protect the site, and restore it to finished condition, which can include backfilling the hole, bringing soil, sod, mulch, or fresh gravel, and putting a new tree in the spot. Most jobs sit somewhere in between, and the honest version of a stump estimate is mostly a conversation about that, not about the stump.
The grindings themselves are a pile of wood chips mixed with soil. Keep them if you have a use for them, though they are coarser and more soil-heavy than the mulch we deliver. If you do not want them, we load the material out and recycle it through our yard.
Planting a New Tree Where a Tree Stump Exists
If a tree is going back where the old one stood, we grind deeper and clear more of the grindings out of the hole than we would for a spot that is just going back to lawn, then backfill with soil so what the new tree gets is a planting pocket rather than a bed of wood chips. It is worth deciding this before we grind rather than after, because it changes the depth we cut and how much material we haul off.
Whether that exact spot is the right one for the tree you want is a separate question, and it is one our tree planting service answers: species selection for Central Texas, siting against the structures and the trees already there, and the planting season. We are happy to do both visits as one job.
