I took my SS4 for a walk in the yard this weekend and let it play outside for a while. Although I would not let it play too hard, or mess around with the big boys, it did a fine job on the smaller, lighter tasks that I put it too.
Mostly I used it to trim shrubbery and sharpen zombie sticks for the grand kids. Not only did it perform well, but when play time was over it cleaned up real easy and did not require any sharpening.
All in all, quite an enjoyable day in the yard.
