I just bought an HRX with the smartdrive tranny, but was using a 17 year old HRB215 with the plastic deck. The deck never once caused any problems, but the tranny finally gave up the ghost. I am thinking about replacing the transmission and keeping it for a spare mower!
But I so far really like the HRX. Smart Drive takes a little getting used to, but I think it is definitely more efficient than mowing with the 2 speed HRB. I intuitively slow down and then realize I could go faster on the straight sections, so I push it a little harder. It rolls well too without the Smart Drive. Ball bearings at all four corners surely helps.
One surprise today was the HRX belched a big cloud of blue smoke on start up. But it ran great and cuts anything very well. I think the dealer went a little too far on adding that initial shot of engine oil. Will change it in a couple weeks for the first time and see if that helps. My HRB smoked a lot at start up, but it also was 17 years old. It never started on first pull though...usually on 4th pull.
