I was just talking with my mowing partner and she is gonna get out of it for a while. We both cut lawns for her father 1 day a week. Apparently the two of them got into a big fight tonight and she doesn't want to cut lawns anymore. So that leads me to believe that I will be asked to cut them all. There are 11 lawns, ranging in size from about 5,000 sq ft to 4 acres. Together, it takes us at our best time 8 1/2 hrs to cut. However at that time, they come out looking like garbage, and we do not cut a good sized area of the largest property. That area would probably add on another 1/2 hr to the mowing time. The lawns are for the most part pretty spread out. Some have a lot of trimming and edging, others have none. Together we use a 61" surfer, and a 72" sit down machine. The 61" machine gets used a lot more because it is closer to the tailgate. What would you say is a good estimate for how much time they will take me to do solo?
