I was wondering how long approx. 20 commercial acres would take to mow (Some rolling hills/Flat area) I have an idea but don't want to under/over bid what the job is worth! I would be using a 1-2 48in exmark walk behind 1-60 inch. Laser Also can you give me what you would charge on this! There is not much edging, but trimming! This 20 acres is spread across 5 different lots, 3 are next to each other, & 2 are next to each other about 5 miles away! This company will probably be a little bit picker then other commercial accounts! I will be paying 2 employees $9.00 each and myself the owner! Thanks in advance!
