16.5 acres, late 1800's thru present. How much per acre just for mowing and trash pick up. the city has to guys that will do the trimming. I know my costs but would like to hear some opinons. We will be using 1 60 in. dixie chopper, 1 36 in. proline, 1 48 in. proline. there will be me and two workers. Minimal trees. and probably about 3 acres that are wide open with no graves.
