I ended up buy a DR Power Grader it toes behind my ATV. It is a lot more versitle than anything else I looked at. The are supose to deliver it tomorrow so I'll let you know how it works. My thinking is, once I kill off the vegitation the scarfire should break up the ground and the drag will cover the seed. in addition I can use it to grade my 600 ft driveway
Go to DR power equipment online and take a look. Their rototiller was very tempting.
