I'm working with a 5600 Toolcat and have 1/2 mile of dirt/small rock road (with a lot of elevation changes) to maintain. Looking for suggestions/advice as to the best implement to get the job done. I need to re-grade 4-8 times a year depending upon rainfall. I'm currently using a pull-behind DR grader which gets the job done but it takes a while, requires many passes, and has no mechanism for crowning or sloping the road.
