2022 Stihl Petrol chainsaws for agriculture and horticulture MS 291
Strong, versatile farm sawDurable 2.8kW petrol chainsaw is a practical all-rounder for farmers, landscapers and gardeners. With the economical 2-MIX engine, fuel consumption is reduced by up to 20% and emissions are cut by up to 50%. Featuring STIHL's long-life air filter system with pre-separation and professional anti-vibration technology, the MS 291 sets a new standard for this type of saw.
Features may include:
STIHL 2-MIX engine- The two-stroke engine with STIHL 2-MIX technology saves up to 20 % of fuel and reduces emissions by up to 70 % compared to STIHL 2-stroke engines of the same performance class without 2-MIX technology.
Carburettor heating (V)- By changing the chain saw from summer to winter operation, the intake air is pre-heated over the engine fins. This ensures that the carburettor does not ice up and you can continue working in freezing temperatures.
Side-mounted chain tensioning- Side-mounted chain tensioning makes it easy to tension the chain safely
Pre-separation air filtration system- STIHL long-life air filtration systems with pre-separation achieve perceptibly longer filter life compared with conventional filter systems. Air drawn in is swirled. The larger, heavier particles are ejected. The pre-cleaned air is routed to the air filter via the pre-separator duct.
Advanced combustion technology- Four overflow channels swirl the fuel-air mix before ignition, allowing for optimum combustion and highly efficient performance. The result is lower fuel consumption and high torque across a broad rpm range.
Compensator- This controller in the carburettor prevents the fuel-air mixture getting richer as the air filter becomes clogged. The correct quantity of fuel is delivered to the carburettor depending on the quantity of air passing through the air filter. This keeps the fuel/air ratio in the combustion mixture constant and hence also the engine power. The filter doesn't need to be cleaned until an appreciable drop in power occurs.
