The Stihl BT 131 earth/ice auger features a larger fuel tank than previous models, so it can work longer with fewer refuels.
It also includes a vertical pleated air filter for better air filtration, extended service intervals, and increased product life, according to the company. Its semi-automatic choke lever enables a simplified starting procedure and the Stihl Quickstop auger brake automatically stops operation if the bit is snagged. The unit is designed for applications such as post-hole digging, fence installation, large planting projects, environmental restoration, and construction. By using an optional Stihl ice auger bit, this auger can be used for construction in icy conditions. The fuel tank is 710cc.
