Thanks guys: These midwest farmers can get a little seed happy! Ok, heres another question...The three saws in my signature, are the only experience I have with quality saws. I dont have much history to compare saws with,,,so,,, a while back I used a friends 5100 Dolmar, cuttung on a standing dead oak (2 to 3 years). Before job was finished my Echo 440 came in so I started using it,,,so I certainly know the difference between the two saws,,,my question is, if I was to step up to a 60cc, is there going to be similiar differences between the 51 and 60 as what I experienced between the 44 and 51??
