Operating on hills
Be very careful when operating the stump grinder on hills because the machine can slip or move unexpectedly. NEVER use the machine on grades of 10° or steeper.
Most stump grinders can be transported in a truck, trailer, van or a large SUV (Sport Utility Vehicle). Most stump grinders are equipped with two lifting handles on each side so that two people can lift the machine if necessary. DO NOT attempt to lift the machine alone. Use safe lifting techniques and DO NOT exceed your physical limitations. Secure the machine with tensioning belts, chains or other approved materials. Consult your rental dealer about specific moving and lifting recommendations.
