We have a condo complex that we mow and once a year around this time we must weedwhack the hill behind the units. The hill is probably 600 yards long by 40 yards wide all high grasses and weeds about 2-3 ft high. We have been forced to send 4-5 guys with whackers all day 7:30-5:30 to take care of this job. Is there a machine that can handle a hill this steep? any one have one or have pics of one?
