In this picture you can see this stump is surrounded by small stones. These are quite common as it is a popular way to decorate and neaten up garden beds. We need to make sure all these rocks are pulled away from the stump, as they can become quite dangerous and cause a threat to windows etc. We do carry barriers around with us at all times, and we would use one in this circumstance to practise safety and caution. We recommend customers move as many of the stones away as possible which will reduce the price in tree stump grinding.
