Sadly, I didn't think to get any "before" pictures of the back yard. But this pile from the neighbor's place gives you some idea of what we were dealing with, before we chopped out the larger trunks and stems.
So it's nice, now, to step outside and see this, instead.
Hey, this guy likes his Chief, too! He's got the 3.5 HP motor, but otherwise it looks like the same machine. I love that the mower has been in his family for "almost 30 years" and is considered an heirloom.
