    The performance and user experience offered by the STIHL MS 261 C-M 20 are nothing short of exceptional. As someone who has used chainsaws in various professional contexts, I found the 50.2 cc engine delivering 4.0 horsepower to be more than capable of handling a wide range of cutting tasks, from felling trees to pruning large branches.

    The M-Tronic™ engine management system was a game-changer in my experience, as it automatically adjusted the engine’s performance based on environmental conditions, ensuring optimal performance every single time I used the chainsaw. This feature made a noticeable difference in the overall efficiency and power of the MS 261 C-M 20, allowing me to complete tasks more quickly and with greater ease.

    STIHL MS 261 C-M Chainsaw vs Competitors

    The MS 261 C-M holds its own against competitors like the Husqvarna 550 XP and the Echo CS-501P. While all three chainsaws have similar power and capabilities, the MS 261 C-M M-Tronic™ system, easy-start feature, and advanced anti-vibration system set it apart from the competition.

    Husqvarna 550 XP

    The Husqvarna 550 XP is a powerful chainsaw, featuring a 50.1 cc engine with 4.0 horsepower, making it a strong competitor to the MS 261 C-M. However, the 550 XP doesn’t have the M-Tronic™ engine management system that the MS 261 C-M boasts. While the 550 XP utilizes Husqvarna’s X-Torq® technology to improve fuel efficiency and reduce emissions, it lacks the precise engine performance adjustments that the M-Tronic™ system provides. Additionally, the Husqvarna 550 XP has a good anti-vibration system, but it doesn’t quite match the advanced system of the MS 261 C-M, which offers greater comfort during extended use.

    Echo CS-501P

    The Echo CS-501P is another formidable chainsaw, with a 50.2 cc engine delivering 4.0 horsepower. While it shares a similar power output with the MS 261 C-M, it doesn’t come with an engine management system like the M-Tronic™. As a result, the CS-501P may not deliver the same level of optimal performance in varying environmental conditions. The CS-501P does have an easy-start system, but it is not as smooth or efficient as the one found in the MS 261 C-M. Furthermore, the anti-vibration system in the Echo CS-501P is not as advanced as the one in the MS 261 C-M, making it less comfortable during prolonged use.

    Seems you overlooked the fact that the Husqvarna 550XP has Autotune, Husky’s version of Mtronic. I’ve owned both and the 261CM is a great saw but I give the Husky a slight edge. I think the bottom line is which brand has the best dealer support in your area.

    Love this saw , it is my all around , go to saw for all size trees , weather it be spruce , birch or red oak , it handles anything you put through it. The only complaint i have is the very limited amount of upgrades and or accessories available for this particular model . I mainly cut red oak in an area with a lot of oak wilt and would love to have a full wrap handle bar for it during the occasional left handed cuts . Also would like to upgrade to a better professional or larger air filter and maybe a full skid plate . Im not sure how a muffler mod would work with the carb not being able to adjust anything but find the performance is exceptional . I just like being heard out in the woods , and show off a little to cutting buddies . Other than that , its by far the best saw in my collection of 63 saws and growing !!!
