I got my MMWS 550 out for the first time today! Stuck it in the Sawhaul on the tractor, hooked up to the grapple, and headed out to clean up some brush and wind damage along some fence rows. I was grinning like the cat that ate the canary after I got done. Funnest little saw I've ever ran. Light and easy to flip around clearing brush. I didn't cut anything huge, mostly just tops and junk 8" and under. I did stop and cut a 16" cube out of an old poplar stump for fun, just to see how it acted with the bar buried. I sat down on the "chair" I had just cut out of the stump, and smoked a cigar to celebrate! I was impressed; its a snotty little bugger. Cut great considering it was a new chain that I haven't even touched with a file yet. I even cut a small dead hedge up for firewood that had fell out into the field. (Osage Orange if you drink tea with your pinky out.) For those unfamilar: dead aged hedge is only slightly softer than rock in my opinion. The 550XP wasn't phased a bit; pulled right through it, no complaints. This is my first Mastermind saw, and after one day with it, it's earned a permanent place on the tractor as my go-to saw for brush work. My 572 just got pushed off it's perch. Never would have predicted that before today! I got a 395 ordered from Randy too, but it'll be my stumpin' and big work saw, so the MMWS 550 will likely live on the tractor for the foreseeable future. Thanks a bunch Randy! I LOVE IT!!!!!!!
