I’ve had a couple guys rave to me about how great the MS 311 is. Perfect for farm or landscape use because its not too big and not too small.
I bought a 391. Love this saw. Very good power. Cuts like an older 361. If you can only have one saw this would be an excellent choice.
i bought a 391 to day and cut two truck loads and i like it alot it dont play around good power
