Thanks for all the great ideas. I have been thinking this over and while goats will not work for this application, sheep and/or cows, etc. will and that would be great to take care of a field that I am getting tired of bush hogging. I also love the idea of solar panels on a truck.
To answer ur ? I walk to most of my jobs and pull my equipment in a wagon. I am trying to figure out a cheap way to mount it to a bicycle soon. I do use gas equipment, but I try to do everything else I can by hand (ex. edging, weeding, etc.) and will maybe try a reel mower soon.
