Sound like some of the posters have not put too much time in at it, if they are still saying how it cuts oak at an amazing rate. Yeh amazing, amazingly slow.
Even with a 90cc plus saw and a sharp rip chain it is slow going in hardwood.
and cutting millions of feet of lumber???? talk about saw life. The most I cut in a day with a chainsaw mill might add up to 2-3 hundred BF of hardwood at that rate, thats 10s of thousands of hours on the saw if millions of feet were cut.
