I have a 1/2 mile rock & dirt driveway with some steep elevation changes that I have to regrade 5-6 times a year. For many years, I've been doing the work with my Toolcat 5600D and a pull behind DR Power Grader. The DR Power Grader has been getting the job done but it is not very aggressive and requires multiple passes over several hours. Plus, it lacks the ability to put a crown on the road. Unfortunately, the DR is on its last legs and will need to be replaced. I am considering just getting a new DR but would like to consider other options. Something that is a little more aggressive and would put a crown on the road would be welcome. Looking for suggestions.
