Hi
I decided to service my mower myself this year, oil is easy to change but
having a heck of time gettin the blade off
to sharpen. Cant find my manual. Is there a trick to getting the blade off.
I've got a Honda Harmony HRT, about 8 years old. Original blade. I was
wondering if maybe after 8 years I should get buy a new blade? Its one of
those mulching blades.
Also, when it runs it seems to rev up and down after a few minutes, does
anyone know whats causing this?

any help greatly appreciated
