I ended up going with the HRX217HYA model yesterday and mowed with it for the first time. I had the bag on and set the clip director to half mulch, half bag. Worked great and cut like butter.
One small annoyance though was the grass would build up along the ridge where the bag sets on the back of the mower, where the two little bars sit in the grooves. So when I would empty the bag, I would have to spend a little more time to clear out that whole ledge of grass so the bag would sit back in the little grooves. Is there a way to prevent this build up right there, or do I just need to empty the bag before it fills up that full?
Thanks
