Overall, I would have to say that the mowing deck could stand to have improved discharge capability. Alternate blades which do a better job of discharge and not so much mulching would help.
Center cutting blade does not get as much drive as outer blades and consequently does not cut as well as outer blades---tends to leave uncut grass in the middle of a mowed path.
Steering bearing has poor surface area for the forces it is subjected to.
Headlight assembly gets dust and dirt inside and is not easy to clean without breaking plastic retaining tabs.
