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.
don't mess about, start off digging a 2 foot square 2 foot deep hole down side of first stump. Use this hole to remove soil that you loosen. Take a sharp trenching spade (not a wooden handle garden spade) and tunnel under and around roots. The further from stump you go the smaller roots will be and easier to cut. would be tempted to dig out the main part of the stump. Get the tops cut off, leave 6 foot or so of trunk to enable you to 'rock' the stump as you dig around it and chop through the roots. Be careful as they can suddenly snap a root and topple over, professional help might be useful.
