I was asked to cut a 5.5 acre property. The growth is approx. 8" high. However no woody growth just leafy growth, there are some small trees but they won't be cut. Here is the question. Is this a job for a bush hog or is it o.k. to use my 60" Toro ZTR? Also, this is my couzin, is 65 to 85 per acre a good price?
