Were finally giving up on the John Deere 63 walk behind. It is an outstanding mulcher, but we have strings of issues with the motor, rear wheels, transmission. I read a lot of good things here on this board about the new Honda HRC216HXA. Besides reliability, very good mulching results are important for us, we mulch Tall Fescue 90 % of the time. For all you who own the new commercial Honda, does it really mulch very well once the twin mulching blades are installed? Thanks for the help John PS: The model our dealer has is a HRC216 K HXA. What does this K mean??
