Different Types of Reel Blades
It is important to understand that Toro reel mowers are
designed and manufactured to optimize available power
from the engine and hydraulic systems. To help do this,
we put a “relief” on every reel blade to reduce the width
of reel blade that contacts the bedknife. This has been
proven to reduce power requirements, as well as allow
the machine to operate more efficiently. This can be very
important, depending on the terrain, type of grass and
amount of grass being cut.
Relief
Ground
Relief
Milled
Relief
Toro has two different methods of manufacturing reel
blades with a “relief”. The reel blades are made from
straight stock steel and then are either relief ground or
the relief is milled in. Either way, there is a relief on the
blade when it is manufactured. NOTE: A small ground
relief is also put on milled relief blades during manufac-
ture.
Spin Grinding (also know as “Flat Grinding”)
With this method, both the reel and the grinding stone
are turning as the reel is being sharpened. It is often
stated that backlapping is not required after spin grind-
ing, because the reel is a perfect cylinder when grinding
is completed. This depends on proper alignment of the
reel in the grinder before sharpening. Also, the bedknife
and bedbar must be straight and perfectly parallel to the
reel when it is mounted. Backlapping will remove burrs
and rough edges, producing a honed edge that will cut
grass evenly.
Cylindrical
Reel
NOTE: If using a spin grinder to sharpen straight stock
reel blades (such as on fairway mowers) some or all of
the relief will be ground off (see Different Types of Reel
Blades above). If you are going to restore the relief that
was on the blade when was manufactured, you will need
to also use the other method of grinding (single blade
“relief” grinding). Do the relief grinding first, then spin
grind to restore the reel to a cylinder shape.
