Rotary Mowers 21
Toro University Technical Training
The most common causes for rotary mowers not
giving a good quality of cut are due to dull cutting
edges and/or bent blades.
Caution: Check cutter blade daily or before mower is
used or stored and whenever mower is serviced. If
bolt holding blade is loose, tighten it before using
mower.
If the blade is bent, the blade should be replaced. A
bent blade will cause two problems. The most
noticeable problem a increase in horsepower that is
required to operate the mower. This is caused by the
fact that when the grass is cut the at the outer edge
of the blade it is higher then the next area of the
blade. The grass is then cut again and again until
the height is the same as the lowest cutting edge.
The same grass blade could be cut several times.
This can take a considerable amount of power to
repeatedly cut the same grass blade.
The other problem is that this will adversely affect the
quality of cut. In this scenario, a very small amount of
grass is cut from the grass blade frequently. This
can cause the top of the grass blade to fray and it
leaves the grass blade with a unhealthy cut edge.
This will usually show up as a brown die-back from
the top of the grass blade.
In this situation the blade should be replaced.
NEVER straighten a Bent Blade as this could
weaken the blade and cause the blade to break.
Carefully examine cutting ends of blade, especially
where the flat and sail parts of the blade meet. When
mowing in dry or sandy areas, sand and abrasive
material can wear away the metal that joins the sail
and flat part of the blade. For safety, it is important
that when any wear is noticed, the blade must be
replaced. If the condition is not corrected and wear
continues, a slot will form. Eventually a piece of the
sail may break off and be thrown from under the
housing, possibly resulting in serious injury to
yourself or bystander.
