STIHL MS 881: The world’s most powerful series-production chainsaw With an output of 6.4 kW, the STIHL MS 881 is the world’s most powerful series-production chainsaw. This extremely capable saw is entirely in its element when used for professional harvesting of large trees and in mobile sawmills. The robust MS 881 with advanced 2-MIX engine, captive nuts, and stop button function is extraordinarily durable and easy to maintain. The efficient HD2 filter increases service life. The premium oil pump ensures optimum oil flow.
With the same overall power and weight of the MS 880, it is also still built in Germany with pro-grade materials such as a magnesium crankcase from our own magnesium casting facility. The MS 881 is a chainsaw to rely on for the toughest tasks.
This 121.6 cm3 powerhouse has an output of 6.4 kW/8.7hp and a huge 8.0 Nm of torque, all from a powerhead that weighs 9.9kg, or 12.7kg with the STIHL Rollomatic ES 75 cm/30” bar and STIHL .404″ Rapid Super chain.
The STIHL MS 881 system weight (powerhead only) of 1.5 kg / kW puts it not far behind the STIHL MS 462 C-M which has an incredible ratio in the 70c class.
It is available in three different bar lengths in the Australian market; 63cm/25” with a Rollomatic ES bar, and the option of a 75cm/30”, 80cm/32“ (Rapid Micro) or 90cm/36“ Duromatic bar.
The MS 881 is one of two chainsaws in the STIHL line-up to run the sizeable .404” Rapid Super chain, which offers the highest cutting performance of all STIHL saw chains, with a full chisel tooth and low cutting resistance. This makes it perfect for pro forestry and wood harvesting.
With an all-new 2- MIX motor this is the only saw of this power and cubic capacity available today that meets the strict EU 5 emissions requirements. There have also been a number of additional refinements beyond the bold and aggressive design and the new STIHL 2-MIX powerful engine.
After pressing the stop switch, it returns to the starting position so the chainsaw can simply be restarted. You just need to press the decompression button and pull the starter cord.
Captive nuts on the slim-line sprocket cover also mean you cannot lose them when you swap the bar and chain. This is a feature that is now standard across our entire professional chainsaw range.
The new oil pump regulates the oil delivery to give the best oil flow for the job at hand depending on the rpm level, which is a must when longer bar lengths are used on professional chainsaws like the MS 881.
What’s more, the new diagnostic socket means the chainsaw’s performance data can be analysed by your local STIHL Dealer when maintenance or servicing is required. If the worst comes to the worst, any fault can be found and quickly rectified.
The proven HD2 filter also increases service life due to its high filtering effect, especially with the fine dust that can be found in a saw mill environment. It is also very simple to clean. You only need to clean it when you notice a drop in performance.
