How Does Stump Grinding Work?
Stump grinding spins a wheel of hardened teeth, shaving the stump away in layers, moving down and out until the surface is flush.
Unless you ask for something else, the chip is left in the hole as backfill and the surface is finished with soil.
Why Is Stump Grinding Easier On Sandy Ground?
Sand is about the kindest material stump grinding ever meets. It cuts fast, it does not blunt teeth, and the machine works at a steady rate from start to finish.
That shows up in the price. Where a job here does slow down, it is almost always because of a buried rock, old fence wire grown into the trunk, or a service line nobody remembered.
How Deep Should A Stump Be Ground?
How deep we go depends on the plan for that ground, and the number appears on the quote before work starts:
- About six inches under grade is enough for lawn, since grass roots stay shallow - Deeper for a new flower bed, so roots meet soil rather than packed chip - Deeper again under concrete, a shed pad or fence posts, with the side roots chased outward - The minimum, and the least costly, if all you need is clearance for a mower
Why Does The Ground Settle So Quickly Here?
Backfill on sand compacts faster than on heavier soil, so the hollow appears within months rather than over a year.
Leave the fill standing slightly proud of the lawn and plan on one top-up. Anything planted in that spot wants deep watering through its first two summers, because the loose backfill drains even faster than the ground around it.
What Should I Mention When I Call?
Three details move the price of stump grinding and removal, and raising them early saves everyone time:
- Buried services of any description, since the wheel hits pipe and cable at working speed - How wide the gate or lane entrance is, since a standard opening admits only the compact machine - Embedded stone or old fencing wire, capable of destroying every tooth on the wheel
