It is one of my favorite attachments!
For brush clearing, it is great. Works well for grading on hard compact surfaces, like gravel.
A note on Tractor Supply: They only show the RR sporadically on their website.
I went to my local store and asked specifically about the RR. The associate found it on the store computer and said it was special order and gave me a rain check with a 2 week delivery (IIRC). I stopped buy in 2 weeks and another manager indicated the order was done under a rain check and could be another month for delivery. Somewhat embarrassed, he searched nearby stores and found one and said he would pick it up and I could have it the next day! So, I came back the next day and he had it in the back of his truck! 1 week later, I get a call from my local store that my order was in! They said, "no problem, they are popular so they would just put it in stock."
So, like all big box stores, the service depends on who your associate/manager is on that day.
