(not in the biz...yet) just curious how much time goes into weekly maintenance. i've heard some guys keep 1 day a week set aside for maintenance (or to cover for rainy days etc.). since i don't run a lawn care business i'm curious what is done on that day. i would assume you clean and sharpen and change oil and stuff. if someone wants to give me a detailed list of a typical maintenance day and time involved that would help me in my decision to start. thanks.
