I used to push mow the entire lot in about 2.5 hours, but these days I usually break it down into 3 separate days of about 45 - 55 minutes while doing other stuff. Dad offered to buy a riding mower (I could have done that myself) but what's the point of exercising in the attic with weights or walking a treadmill when you can do something useful? We've got 70 acres that is mostly wild now. (the arrow of wildness pointing NNE in this Google maps pic)
