Not sure if I remember all the details, but seems my use worked best if I kept a 'roll' of dirt/debris ahead of the nubbed roller, and the clean dirt spilled over the top of the roller. Had an angle set that would keep the 'roll' of dirt/debris about the right depth by using the hydraulic angling cylinder. Not sure how easy that will be if manually setting the angle. But you will be able to quickly establish what is working and what is not. I'd start with but a small angle and increase it as you see how it works. Set the depth with the depth wheels.
At my son's place, we were pressed for time so started when the ground was a bit damp. Soon learned that the Harley rake worked pretty good when it was damp, and it quickly dried for a second pass that leveled everything out for grass seed planting.
Angling will allow you to work the dirt back up a slope to a small extent, which helps if some washing and erosion has taken place.
Hope this is of some help. You will like it, I'm sure. /forums/images/graemlins/wink.gif
