Large old-growth oak tree stump 30+ inches diameter in residential yard

The job: Specialized equipment for grinding 24+ inch diameter stumps and old-growth hardwood across Lake Country. Same per-inch pricing as standard jobs ($3–$4/inch), just more time on site. Most large stumps run $360–$900 depending on size, species, and cleanup add-ons.

Older Lake Country neighborhoods — particularly in Oconomowoc, Delafield, and the established Hartland-area homes — are full of legacy oak, silver maple, cottonwood, and elm trees that grew large for decades. When those trees come down, the stumps left behind are often 24, 30, or 40+ inches across. Standard residential stump grinders can struggle with these. We have the equipment for them.

What makes a large stump different

Time on site. A standard 14-inch stump takes 30–60 minutes. A 30-inch stump can take 90 minutes to 2 hours. A 50-inch ancient oak can take 2-3 hours.
Equipment size. Compact grinders that fit through a 36-inch gate may not handle a 30+ inch stump efficiently. We bring larger equipment when we know we're working on a big one.
Root flare. Big stumps have big root flares — the wood spreads outward at the base. We charge against the widest measurement, including flare.
Hardwood species. Oak and old maple grind slower than ash, willow, or pine. Old oak is the slowest of all.

Pricing examples for large stumps

Diameter	Grind only	+ Cleanup & topsoil
24 inches	$290–$385	$650–$745
30 inches	$360–$480	$810–$930
40 inches	$480–$640	$1,080–$1,240
50 inches	$600–$800	$1,350–$1,550

When grinding still beats removal — even on big stumps

Many homeowners with 30+ inch stumps assume they need full removal because of the size. They usually don't. Grinding works fine for stumps of any diameter as long as you don't need clean dig in that spot for construction or a pool. A 40-inch oak ground to 6 inches below grade leaves a usable spot you can plant grass over within days, at half to a third of the cost of full removal.

Common questions about large stump grinding

How big is a "large" stump?

Anything 24 inches in diameter or more, measured at the widest point of the stump and root flare. Old-growth oak, silver maple, cottonwood, and elm in older Lake Country neighborhoods routinely hit 30, 40, and even 50+ inch stumps.

Can stumps be too big to grind?

Almost never. We have equipment that handles 50+ inch stumps. The job takes longer (90 minutes to 3 hours instead of 30-60), but grinding still works. Removal is usually only needed for new construction or pool installation, not because of stump size alone.

How much does grinding a 30+ inch stump cost?

At $3–$4 per inch, a 30-inch stump runs $360–$480 for grinding only. Add cleanup and topsoil and you're typically in the $700–$900 range. Larger 40–50 inch stumps run $480–$800+ for grinding.
