Believe it or not, I did this lawn for free!
Well the home owner is my friend who often barters with me & does a few errands for me.
Basically if I'm too busy (lazy), he'll be a second driver for my weeders, or he'll drive out to pick up repaired equipment/supplies.
Actually, I have a nice tear in my toro's bag... I need a new one!
I have 2 customers with that lawn size, & they have a backyard 2.5/4 the size of the front! Another customer is like both of them combined..
I need a zero turn.. so I can sleep & work...
As for the time it took me to mow... I don't remember, it felt pretty short... it was one of those days where I felt like a mowing champion!
