Yes, I had been driving on the area of the circle for quite a while(pretty well packed). The blade dug right in and pulled up the sod though. A little more weight here would have probably been better but it came up after a few passes. The clumps of sod tended to hang up on the top of the blades untill they broke apart. If you have tilled a bit where you are going to work, that will help with this type grader.
The blade rippd out some pretty big rocks in the process. We call them Sequim potatoes around here and I sure grew a lot of them this last week. It took a little bit of trial and error but once the toplink was set, it shaved the high spots nicely and deposited the cut material into the low spots. With a little practice, I was also able to leave collected rocks in groups for easier collection. Large groups of rock tended to interfere with the operation as the grader will ride up on them like it is on ballbearings.
Just a little work in the evenings and a bit on Saturday and it is done. I have 20 yards of 3/4" crushed rock on the way tomorrow afternoon so I will see how well it spreads then. I am sure it will work well as it did a great job with loose dirt/sand.
