How Does Stump Grinding Work?
The machine used for stump grinding and removal carries a spinning wheel set with hardened teeth, which reduces the stump to chips. It cuts downward and across in passes until nothing remains above grade.
Unless you ask otherwise, the chips stay in the cavity. Most people leave them there as fill and finish the surface with topsoil.
How Deep Should The Stump Be Ground?
How far down the stump grinding and removal goes is settled by your plans for the ground, and it is written into the quote in advance:
- Under grass, half a foot or so below grade will do, as turf roots stay near the surface - Under planting, further down again, so roots meet earth instead of chip - Under a slab, a shed or fence posts, deeper still, with the lateral roots chased outward as well - Purely to stop the mower catching, which is the shallowest and least expensive version
What Makes The Job Take Longer?
Mention these three when you call, because each of them moves the stump grinding and removal figure:
- Anything running underground, since the wheel reaches pipes and cables at full revolutions - How wide the gateway is, given that only the compact machine passes a standard opening - Rock or old wire embedded in the wood, capable of destroying an entire set of teeth
Why Does Stump Grinding Take Longer On Clay?
The clay layer under Cainsville is close to the surface, and tree roots that could not push down through it have spread sideways instead.
A stump on this ground often has a wide flat root system rather than a deep one. Grinding the visible stump is straightforward, but the surface roots reach further than the stump face suggests.
Does The Ground Settle Afterwards?
It does. Over the twelve months following stump grinding and removal the chip and soil mixture compacts, so plan on topping it up once.
Leave the fill standing a little proud of the surrounding ground. A dip in clay gathers water and keeps it, since there is nowhere for it to drain.
