I am about to retire this coming spring. I have been a turf care (schools, golf courses) person for about 25 yrs. on a part time basis. When I retire from being a H.S. principal, what kind of income can I expect to make working 3-4 days wk in the Nashville, TN area? I already have a truck, trailer, mower (JD 757 Z-Trak), blower, hedge trimmer, and Stihl FS80 trimmer........... Any and all advice will be greatly appreciated!
