A stump grinder uses a spinning blade fitted with carbide tipped teeth that scrape away at the stump. Bear in mind that a stump grinder can only work to a limited depth, normally up to 10-12 inches. If you feel up to it, stump grinders can be hired by the day at most local hire shops. If you decide to use a contractor to do the work for you, expect to pay a minimum of around Â£65 plus VAT for the smallest of stumps.
I just finished digging a thirty foot three foot deep trench. It took me four and a half hours and I was working in rocky clay. A pick and good shovel are nessesary. You are going to have to dig it 12 to 16 inches wide to have enough room to stand in it as you dig. Watch out for buried pipes and wires.
