Iv heard that either goats or sheep will eat the grass perfectly level with out leaving holidays or clumps. Now if this is true, couldn't you offer that as an alternative to a lawn mower for some customers? How about if there's a field with lots of bushes and steep hills that needs to be cleared. If you set a bunch of goats or sheep in there, wouldn't they do the job in a timely fashion? I had a clearing job last year and there was hills and rocks with thickets. It was kind of dangerous because we couldn't get a machine in there. Just loppers and a chain saw. I could have fenced it in and set loose the animals. Come back in a week or two, and its done. I'm bored and its the off season so I'm thinking about things.
