I have a 1/4 mile driveway to maintain (dirt and creek rock from 1"-3" in size) with drainage ditches on both sides. Parts of driveway have a significant grade so maintaining a good crown is important. Need to maintain the road 1-3 times a year. I have a 5600 turbo and a combo bucket. Considering a tilt tach to use with my combo bucket for the job vs. a soil conditioner. Would appreciate any suggestions regarding best attachments for this kind of job. Rent vs. buy? If buy, reasonable prices new or used. If used, anybody have something for sale close to middle Tn.?
