When quoting stumps from photos we need perspective. Place an item on the stump or beside the stump so we can get an indication of dimension. Something simple like a shoe, garden rake or brick. Also what affects tree stump grinding pricing the most is access. The larger the stump grinding machine we can get to the stump the cheaper the stump grinding price will be. ie measure gate widths and pathways.
