With the help of the STIHL iMOW® fixing nails, you can anchor the STIHL perimeter wire in the lawn along the edge of the area you want your STIHL iMOW® robotic mower to mow. The material-saving design of the fixing nails means that they are barely visible after they have been driven into your lawn. If the ground is too hard and dry, it helps to water the mowing area first so that the iMOW® fixing nails can be driven in more easily. Positioning the fixing nails is one of the first relevant steps in your STIHL iMOW® robotic mower installation.
