There is a good case for Maint free stuff, there are some pluses. I am just a little bit comfortable knowing some lubrication is getting to the bearings for long range serviceability. In my experience bearings also are quieter running after a bunch of hours on them. At least at this time there is still a choice usually, though the mower I just bought that is considered the best on the market of its type, by most, has not one zerk or serviceable point on it except engine of course. I can handle it.
