I am doing this part time. I am a teacher and a coach. I have bid on our school lawn. It is about 35 acres. I talked to the maintenance and he said it takes them all week during the summer to mow it. I'm afraid I wont be able to get it all done in a week. They have four 60" JD tractor mowers. I have one 60" JD 757. It will be especially tough during school days in the spring and fall. I could cancel that and just do residentials which I have no customers yet. The school would pay alot more though. I bid $910 a cut. Could I get it all done?? By the way its mowing only, mostly flat, such as a football field, and its open in two places about 10 acres.
