You're right that loading the bucket really isn't going to happen but not so much because of the straps as because of the rake itself. With the bucket parallel to the ground the second set of teeth are pointing down and a few inches below the bottom of the bucket.
I got mine last summer and can't say enough good about it although I am jealous of the new "yellow" look (mine's black). Kidding aside though, it's important to remember that every attachment has a purpose and a task for which it was designed (hopefully). Things that are "multi-purpose" usually are ok at a few things but "great" at none.
The RR is a rake on steroids...it's head and shoulders above a "york" for brush removal and, after one develops the "touch", equals the york in traditional "rake" mode.
It's NOT though, a toothbar and if one is expecting it to be that they will be disappointed....different jobs and they require different attachments.
My decision was made as a choice between the RR and york (based on how I planned on using it. I can only say if I had it to do over I'd do exactly the same.
BUT....I also added a toothbar and wouldn't give that purchase a second thought either. I really don't think one should consider it an "either/or" choice but that both are pretty close to being essential "add ons" (depending on your needs and how you use your machine). The good news is that both are relatively "cheap"....the REALLY good news is that you would be hard pressed to find ANY attachment(s) that offer better "bang for the buck".
