[AT] chainsaws now Hydro Ax

[Mike]

I noticed that too Charlie, he seemed to have to stop and let the blade(s) build up speed again. It is hard to tell the diameter of the trees however. Still an impressive machine. There were other videos on YouTube that made me question the intelligence of the video taker, way too close for the size of debris these things can throw. Mike M

To be honest with you, compared to the one the guy here has, I believe the 
one in that video clip has hydaulic pump problems.  The one here does not 
bog down like that.  When he wants to cut down a big tree he just tilts the 
frame back a little, walks up to the base of the tree and puts light 
pressure on the hydrostatic drive of the tractor.  The cutter just sits 
there and eats on the tree as if you were swinging an axe at it.  Cetainly 
you can bog any of them down and that stuff in the video might have been 
tougher than it looked but it just seemed like it was bogging down a bit 
early.
