Hi, could anyone offer any advice on removing the tree stump in the attached pictures? Been hacking away at it for a few days now and am losing my patience. I suspect the answer is to keep going, however, if anyone has any alternative advice (burning etc...?) I will take any suggestions. I am looking to remove the stump as quickly as possible, therefore leaving it to decompose is not an option. I did consider hiring a stump grinder but the only access to the garden is through the house and most of the grinders appear to be too large for internal doors.
