Hi elevatorman, this is a quote from a reliable source:
"New bedknives are certainly
not true coming from the factory. Every bedknife that gets installed on a bed bar needs to be
ground properly in order to achieve a consistent quality of cut. The bedknife is the single most important factor in achieving a great quality of cut. The bedknife�s job is to position the grass before the reel blade cuts it. Depending on where the position is will depend on how clean and consistent your turfs after cut appearance will look".
I have to leave shortly, but will take a pic of mine asap.
