I cut the end off of my middle finger with a hedge cutter some years back - again fixable but the nerves have never been the same since! Note to self - don't stick your fingers in sharp places and they'll stay intact!

I had the saw out again today and really pushed it. The biggest log I managed was sycamore about 14" round and the little tractor really wasn't impressed! I had to pull it out and go in from the other side as it hit the blade stop before it made it right through. After attacking some much bigger stuff I've come to the conclusion that it handles up to 9-10" with no bother at all. Anything over that and I need to be a bit considerate and not just ram it through hard!
