I looked through the first page of threads on this forum and didn't see anything related to this. Here is what I'm wondering... For you guys that have big lawns... do you have a set price per acre? How big is your mower that you use for that price? A guy has 1.5 acres that he wants cut and I'm trying to see what others are doing to give me something to reference with my little ZT 34. I found a mowing calculator online that said I would cut 1.09 acres per hour with a 30" wide deck @ 4mph. I used 30" instead of 34" to account for the overlap. So if that calculator is correct I think I'll be charging around $90 for that 1.5 acres. This particular account would be mowing only... no trimming.
