Going to bid a park district with about 15-16 acres of area to mow here is central IL. In doing this I will add a Kubota ZTR with a 72" cut. Can you give me an idea on how you all bid a job of this size? I am used to Residential areas. What do you guys shoot for on a per acre rate or hourly rate? The biggest part of it will be wide open running with about 30-45 min trim work. Thanks in advance!
