A silver birch in the neighbour's garden had grown too big and was threatening our house. It had also expanded over the years and bowed and broken the concrete base slab beneath the fence.
The neighbour had it cut down and now I've pulled out the broken slab and am trying to find a way of cutting away enough of the remaining stump so that the replacement slab will sit level and at the right height. This has meant excavating down about 12" below gound level to expose the stump where it flares out to the roots. I've had some success in cutting down vertically into it with my 14" chainsaw but don't have room to get in sideways at a low enough depth to cut off the bit I've separated from the main stump. On top of this there are stones everywhere mixed up with the stump and I've ruined one chain. Can always re-sharpen it but a 15 minute sharpening session is wiped out in a second when the chain hits another stone or some grit.
My neighbour says I should just drop in the slab and then cut the fence panel down but I don't want to bodge the job.
Any suggestions? Is a stump-grinder the sensible answer? How deep will a stump grinder go below ground level?
