[AT] chainsaws now Hydro Ax

> What is the cutter---just a big chain rotary flail?

Much like a brush hog, heavy steel blades on a large center arm.  The blades
looked to be at least 3/4 thick.  The operator told me that the tips
approach 200 mph and with Ozark rocks they quit sharpening them and just
replace the blades when worn out.  It turns big rocks into gravel.
