I purchased a Honda HRX217HYA about 4 years ago and its been running fine. Out of storage this season I've noticed what appears to me to be a drivetrain issue. When engaged only the left rear wheel drives rather than both wheels. (Frankly, I'm not certain this is incorrect but don't believe that was always the case.) As a result, the mower doesn't move as well as I'd like up hills and is somewhat difficult to turn left. Right turns are easy because the left rear wheel is turning. Further, the right rear wheel doesn't turn easily by hand.
Any thoughts?
