Odds are the blades are worn or dull on the extreme edges. I have a JD
series tractor and the blades seem to like to round over on the very
tip just enough that they do not cut right, even though the rest may
appear sharp, causing the blades not to cut right and leaving a strip
of standing grass. Seems like JD is pretty common with this happening,
as there is not a lot of overlap on the blades cutting areas. A set of
new blades or resharpening the ld ones should solve it.

Also Some grasses are tougher to cut than others, so thats part of the
reason you may or may not have these strips all the time, and a dull
or worn blade don't help.
