Just got a ratchet rake for the loader on my 400. I only had 20 minutes to try it today, grading a small section of my gravel driveway. Loosens a lot of packed material back dragging with a little down pressure and the bucket level. Grades nice and even with the bucket on float. Can't really go forward grading as it digs in and lifts the front of the tractor. Need to try digging up some small brush and a few rocks when I get more time. So far, so good, a really rugged piece of equipment.
