Lawn Mower Blade
Types
The lawn mower is
an essential part of today household. With the
prices of maintaining lawns increasing, it is
necessary to know the details regarding blades
so you can select the right one for
you.
Know the type of
Lawn Mower Blade You Have
The lawn mowers
come in different varieties. Some are walk
behind and some are motorized. The blades used
in each type of lawn mower will vary. However,
there are just two types of blades in the lawn
mowers
Reel Type:: The
first one is the rotary type that you find in
walk behind lawn mowers . These are generally
bigger and are visible from a distance. Reel
blades operate against a stationary edge and
any grass that comes within the rotary and
fixed blade is cut by shearing action. The reel
blades of the manual walk behind lawn mowers
are generally 8 to 10 inches in diameter and
are pushed by the person mowing the
lawn.
The volume of the
grass cut depends on which the speed with which
the lawnmower is pulled and is generally low
for the manual one. Some of the walk behinds
have a motor up to 4 hp and are quite
powerful.
The blades are
arranged on a spiral on a cylinder and cut the
grass by shearing action. The gap between the
blade and the bed can be adjusted very easily
and this is a great help to the
operator.
Sharpening reel
type of lawn mower blade requires some skill to
ensure maximum work from the blades. If the
blade of grass is missed by one blade, it will
not be cut by other the other blades and back
and forth movement of mower over the area will
be necessary to ensure complete cutting by the
mower.
Blade type: This
type of lawn mower blade is used in motorized
lawn mowers where the operator can ride the
lawn mower. The blade hovers over an area and
is rotated at very high speed and the action is
like that of a sword moving fast so that
anything that comes in its way is cut
instantly.
Since it is a
high-speed action, the grass in area is
completely cut quickly and the mower can move
rapidly over the entire area. This ensures high
rates of cutting and is therefore useful for
large areas. The grass is cut in just one pass
and multiple passes as in the reel type of
blades are rare.
It is necessary
that there to ensure that there is no foreign
material on the lawn as the foreign material
can damage the blade quickly and sometimes it
can be damaged beyond repairs. There fore it is
necessary to have an inspection of the area
before starting cutting of the lawn. If you
find a growing shrub, it is better to remove it
manually.
Some of the
commercial models have more than one blade and
the areas on which they operate overlap so
ensure complete mowing. The blades are 18
inches long; (maximum) and three blades may be
employed to cut a pass width of 42 to 50
inches.
Sharpening of the
blades does not require great skills as the
sharpness and speed works for an effective job.
The sharpening can be done very quickly, but
the balancing has to be done very carefully as
the blades move at high speed and unbalanced
blades can cause vibrations and operator
discomfort.
