STIHL MS 251 Petrol Chainsaw | 35 cm
Robust petrol chainsaw for harvesting firewood in the woods
Product description
The STIHL MS 251 is a robust, compact petrol chainsaw that is particularly suitable for harvesting firewood in the woods. With higher engine output than the MS 231, it allows effective work even with thicker trunks. The durable .325″ RM3 Pro saw chain makes it a robust companion for home users, farmers and tradespeople.
Common problems
When harvesting firewood in the woods and working with thicker timber, the same limits often appear:
- More compact entry-level saws quickly reach their performance limits with thicker trunks
- Standard saw chains wear faster than desired during robust continuous use in the woods
- Frequent filter cleaning interrupts the workflow in dusty conditions
Solution
The MS 251 tackles this with a powerful 2.2 kW STIHL 2-MIX engine, the durable .325″ RM3 Pro saw chain for robust continuous use and a compensator that keeps engine output and consumption constant for a long time despite increasing filter contamination.
Key features
- Robust petrol chainsaw with 35 cm RM3 Pro cutting attachment
- STIHL 2-MIX engine with 2.2 kW (3.0 hp) output
- Durable .325″ RM3 Pro saw chain for continuous use in the woods
- Side chain tensioning for safe retensioning
- Tool-free fuel cap for quick refuelling
- Compensator keeps performance and consumption constant over time
- Single-lever control for safe, comfortable operation
- STIHL anti-vibration system for more comfortable working
Highlights
Powerful engine for thicker wood
The 2.2 kW STIHL 2-MIX engine offers more power reserves than the MS 231 – ideal if you regularly cut thicker trunks too.
Durable RM3 Pro saw chain
The robust .325″ RM3 Pro chain is specifically designed for demanding continuous use in the woods and stays sharp for longer, even with intensive use.
Compensator for constant performance
A control system in the carburettor automatically compensates for increasing air filter contamination. Engine output and fuel consumption stay almost constant over a long period.
Single-lever control
Start, stop and run are controlled with a single lever. Your right hand always stays on the handle, making operation safer and more comfortable.
Side chain tensioning
The tensioning screw is operated from the side through the sprocket cover. This prevents your hand touching the sharp chain when retensioning.
Comfortable working
The STIHL anti-vibration system significantly reduces strain on arms and hands during longer work in the woods.

Frequently asked questions (FAQ)
Who is the STIHL MS 251 suitable for?
The STIHL MS 251 is aimed at home users, farmers and tradespeople looking for a robust chainsaw for harvesting firewood in the woods and working with thicker timber.
What is the difference between the MS 251 and the MS 231?
At 2.2 kW, the MS 251 has more engine power than the MS 231 (2.0 kW) and uses the more robust .325″ RM3 Pro chain instead of the finer 3/8″ PM3 chain – ideal for thicker wood and more intensive continuous use in the woods.
