I was asked to bid on a big county park in the area. I take care of 2-3 smaller parks about 10 acres or less now. I was wondering if anybody could tell me how much i should charge to mow about 33 acres every week, 10 acres every other week, and 25 acres to be brush hogged about 4 times a year. Our mowing season goes from April 15 till October 31(weather permitting). I have a 60" Exmark ZTR rider right now. If I got the bid I will buy another machine. I was also wondering if anybody knew how long it would take to mow 33 - 40 acres. I was looking into getting a 72" machine. If anybody could give some ideas.
