Dear Rick,

Thank you very much for your inquiry. Topdressing your lawn is certainly the way to go, short of a renovation. Where the septic lines are, you might have to physically add soil as the topdressing operation is designed to provide a small layer with each pass. The problem as I see it, is finding a topdressing machine to work with. I do not know if rental operations carry these per se, as they are normally reserved for golf courses and athletic fields. One thing running through my mind is a large type of manure spreader. However, the caution flag goes up in terms of the tires from the typical farm type and damage that could be done. I have seen large vehicles designed to distribute fertilizer and topdressing to golf course fairways that I believe could do your work as they are equipped with wide turf tires (this will not be cheap by any means, but it will be less work for you than a do-it-yourself renovation.) These vehicles are not owned by the golf course so they are for hire. Perhaps we can get some direction from our other readers if they know where these vehicles can be rented.

Again, thanks for the question and let me know if you have more. Sorry I could not be of more specific help. Your question is a tough one with no easy solution.
