Very good indeed .... wish it was more common in the US, but I suspect the availability of "cheap" (& potentially illegal) migrant labor has partially slowed the mechanization of many tasks here.
There almost seems to be a mindset of "Why invest in machines if/when laborer's can be hired cheap (and potentially off the books) but charged to the customer at higher rates?" That's not always the case, but until those that think like that get undercut on enough jobs it's unlikely there will be interest/market beyond the enthusiasts anytime soon. Particularly given how much more likely it is to see one large tractor pulling a rotary cutter and a crew of individuals running string trimmers in many of the areas I've been in and around...... of course if they are government employees or include prison laborers doing the work then there also isn't much of a profit or cost-reducing incentive either.
......almost makes me wonder how hard/costly it is to import equipment from Europe (or at least implements).....
