The STIHL MS 311 FarmBoss is a powerful petrol chainsaw built for tough cutting jobs around farms, properties, and rural blocks. With a 59cc engine delivering 3.1kW of output, it’s ideal for felling medium trees, cutting firewood, and clearing storm damage.
This model features STIHL’s advanced anti-vibration system for improved comfort during extended use, and a long-life air filtration system that reduces maintenance intervals. The 50cm (20″) guide bar provides extended reach and cutting capacity, while the high-torque engine ensures consistent performance under load.
The MS 311 also includes a side-access chain tensioner for quick adjustments and a decompression valve for easier starting. It’s a dependable choice for users who need serious cutting power without stepping into full professional-grade territory.
