About the STIHL BT 131 Petrol Earth Auger
STIHL BT 131 Petrol Earth Auger – Precision Power for Demanding Groundwork
Whether you’re installing fencing, planting trees, or preparing groundworks for a construction project, the STIHL BT 131 Petrol Earth Auger delivers fast, efficient, and precise hole drilling time after time. Built for professionals in landscaping, agriculture and site work, this dependable petrol post hole borer is expertly engineered to take on very challenging conditions. Its robust build, superior safety systems, and powerful 4-MIX® engine, make the BT 131 everything you need in a ground auger—and more.
Power and Efficiency from the STIHL 4-MIX® Engine
At the core of this STIHL post hole digger is an advanced STIHL 4-MIX® engine. Combining the benefits of both two-stroke and four-stroke technology, it delivers high torque while running on a simple petrol-oil mix, removing the need for a separate oil circuit. This makes the BT 131 more compact and lightweight than other petrol post hole augers, with less routine maintenance to worry about. The 36.3 cc engine produces 1.4 kW of power (1.9 hp), providing the grunt needed to tackle dense soils and varied ground conditions. This petrol hole borer is fully compliant with the EU’s strict Stage V emissions standards.
Comfortable Handling and Smooth Operation
Despite its strength, this STIHL petrol auger remains very easy to handle. STIHL’s anti-vibration system includes integrated buffers and spring elements, which help dampen vibrations before they reach the handle. That translates into greater user comfort and better control when operating the machine. A generous hip pad rests snugly against the leg or body for added stability, giving you the precision required for clean, vertical post hole drilling.
QuickStop Brake System for Added Protection
The STIHL BT 131 is more than just a standard petrol post hole digger—it’s built with a number of intelligent safety measures too. Activated by a release lever, the QuickStop drill brake system halts the earth auger instantly if the drill jams unexpectedly, helping avoid potential injury. As this lever also serves as a reverse rotation lock, it makes releasing a stuck bit straightforward, without the use of tools.
Designed for Ease of Use and Longevity
STIHL understands that professional users need tools that are both straightforward to operate and built to last. This STIHL auger ticks both boxes. Its single-handed multi-function handle consolidates all essential controls, meaning you can manage the machine comfortably with either hand. Starting the petrol hole digger is quick and straightforward, while the large 0.7-litre fuel tank supports longer operating sessions with fewer interruptions. Maintenance is minimal—the earth auger drill’s long-life air filter is easy to access and rarely needs replacing, saving you time and money.

Capable of quickly and efficiently drilling holes up to 300 mm in diameter, this earth borer works across a variety of job types—from post hole drills for fencing to tree planting and foundation preparation.
