At one location, two 1 acre rectangles exist. The first has one obstruction and takes 17 minutes, 3 1/2 Ac per Hour. The other has a small building and some equipment and it requires 20 minutes, 3 Ac per Hour. At another location, 2.25 acres broken into 7 areas require 1 1/2 hours, 1 1/2 Ac per Hour. Grass clippings are not collected at either site. But if the ground is wet it is stuck and there goes the production.
