I have found on the LS machine traveling straight into a ditch and up the other side works better than trying to aerate along side the ditch. The only problems I encounter using the unit is trying to travel across a sloped area. The bottom half of the unit sinks the tines sending power to the upper side tines which will just spin on the top surface of the ground or grab and try to send you down the hill. Other than that I love the machine. I can only compare it to my former split drive classen.
