A. Caxton
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.
