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
Is it the wrong group? ;^D
The mounting bolts for the blades on most mowers gets hard to remove because
of corrosion. Use WD-40 on the threads every time you pull it off to sharpen
it and it should be sharpened whenever you see any tearing of the grass
instead of a clean cut. This will reduce brown spotting.
Personally, I dislike mulching blades as they are a bear to sharpen because
of all the twists and turns that, supposedly, mulches the clippings. If you
decide to buy one, be ready to pay more for sharpening or buy a small angle
grinder and a blade balancing cone so you can do it yourself. Also, your
bagging attachment will not work as well or not at all. . . .no airflow from
Back when I was a teen, I just mowed in an inward spiral pattern that threw
the clippings onto uncut grass then the standard blade recut them over and
over. By the time I got to the middle, there was but a handful left to
scatter on the new mown lawn.
The surging could be moisture in the fuel, dust and dirt in air cleaner or
just needing a good tune up. If it's moisture, a tablespoon of HEET will
clear it up. Don't let it go too long or it can damage the carburetor.
Also, IIRC, the bolt that holds the blade in place on my mower is
*left-hand* thread. You might want to clarify whether or not yours is/are
too. If the bolt(s) is/are just too darned tight, you might want to use a
6-point wrench or socket on the bolt(s).
