How Stump Grinding Works
A stump grinder is a machine with a rotating cutting wheel fitted with carbide-tipped teeth. It chews through the stump and major surface roots, reducing everything to a pile of woodchips and sawdust.
We grind 200 to 400mm below the natural soil level — deep enough to lay turf, plant a garden bed, or pave over the top. The deeper roots stay in the ground, but without the trunk and canopy feeding them, they'll break down naturally over a few years.
This is what we do on the vast majority of jobs across Orange. It's quick, it's clean, and it doesn't tear up your yard. A typical residential stump takes 15 to 45 minutes. Hardwood species like Elm take a bit longer — dense timber means slower going.
How Full Stump Removal Works
Full removal means digging the whole thing out — stump and major roots — using an excavator. You dig around the root ball, sever the roots, lift the whole mass out of the ground.
What you're left with is a big hole. It needs to be backfilled with clean soil and compacted. The root ball and contaminated soil need disposing of.
It's a bigger operation. Heavy machinery, significant ground disturbance, and real potential to damage paths, garden beds, and underground services in the process. The cost and disruption mean we only recommend it when there's a specific reason the roots need to come out completely.
Side by Side Comparison
Cost: Grinding runs $150 to $500 per stump in Orange depending on size and access. Full removal is $500 to $2,000+ once you factor in the excavator, labour, soil disposal, and backfilling.
Time: Grinding is 15 to 60 minutes. Full removal can take several hours per stump.
Damage to your yard: Grinding leaves a small pile of chips and a depression that settles over time. Full removal creates a crater that needs serious backfilling.
Roots: Grinding leaves the deep roots to rot away naturally. Full removal gets everything out.
Regrowth: Some species — figs and certain natives around Orange — can reshoot from roots left after grinding. A hit of herbicide on the ground-out area prevents this. Full removal eliminates the issue entirely.
Building over the site: If you're pouring a slab, building a retaining wall, or putting in a pool right where the stump is, full removal makes sense — you don't want root material decomposing under your concrete. For lawns, gardens, and general landscaping, grinding is more than enough.
What We Recommend for Most Orange Properties
Grinding. Nine times out of ten, it's the right call. Faster, cheaper, less disruptive, and perfectly adequate for anything other than building directly on top of the stump site.
We recommend full removal only in specific cases: construction is planned directly over the spot, the root system is actively cracking foundations or blocking drains, the species is known to throw up aggressive suckers and you don't want to use herbicide, or you're doing a full site clear where the excavator is already on-site anyway.
Our arborists will have a look at your stump and tell you which method makes sense based on what you want to do with the space, what species it is, and any site-specific issues. We run stump grinders across all areas of Orange and can usually get it done within a few days of the tree coming down.
What About All Those Woodchips?
Grinding produces a lot of chips — roughly two to three times the volume of the original stump, because solid wood becomes loose, aerated material.
You can keep them. Woodchips make great garden mulch. We'll spread them on your beds or pile them wherever you want. They break down into good soil conditioner over 12 to 18 months.
Or we take them away. We'll remove the chips and excess soil, leaving the area ready for your landscaper. Small extra charge depending on volume.
One thing to expect: the area will settle over the next few months as the remaining root material underground decomposes. Top it up with soil and seed after a couple of months to keep things level. A lot of our Orange clients get a turf patch laid over the spot — establishes nicely within a few weeks during the warmer months.
Frequently Asked Questions
How deep does the grinding go?
Minimum 200mm below ground level, up to 400mm if you need it. Deep enough for lawn, garden beds, and standard landscaping.
Can you get a grinder into a tight backyard?
Usually, yes. We carry a range of machines — from compact units that fit through a standard garden gate to larger rigs for big stumps. Most spots across Orange are accessible.
Will the leftover roots cause issues?
They decompose naturally over 2 to 5 years. They won't regrow or cause structural problems. The only thing to watch for is suckering from certain species, which a herbicide treatment sorts out.
