I was asked to give an estimate to clear a hill side of mostly waist high grass and weeds. The hill stretches at least 150 to 175yards long and an average height of 300ft. The angle of the hill is very, very steep. Its almost to the point where you need to go down and brace yourself with your hands. There is no way any type of mower would be able to handle this hill. Also they wanted it raked after we cut. I know this question is asked all the time, but given the basic layout any ideas on what to charge. Thanks in advance.
