3.4 DANGEROUS AREAS OF THE MOWER
DANGEROUS AREAS – RESIDUAL HAZARDS
The riding mower is designed so that when properly operated in perfect technical condition, it poses no danger
to the driver and his/her surroundings. Nevertheless, there may arise situations during operation, maintenance
and adjustment that pose a danger to workers if they are not aware of them and do not adhere to the safety
instruction here provided. These hazards represent so-called residual hazards – they are hazards that remain
even after all preventive and protective measures have been considered and implemented. Residual hazards are
present during use, maintenance and adjustment of the mower. Therefore, every person that comes into work
contact with the mower must know these hazards and must adhere to all recommendations for their mitigation.
(1) MOWING BLADES
Rotating mowing blades are very sharp and coming into contact with them creates a serious risk
of injury to limbs. Therefore, do not put your hands or legs underneath the mowing deck cover.
Never put any part of your body near the rotating or moving blades. Do not attempt to use your
hands or other temporary items to stop or slow down moving mowing blades!
(2) GRASS CATCHER LIFTING/LOWERING MECHANISM
When lifting and lowering the grass catcher, an area is created inside the mechanism where there
is a risk of injury comprising of being pulled in, crimping, compression or crushing of upper limbs.
It is, therefore, forbidden to approach the mechanism while it is being moved. Maintenance and
adjustment of the elements of the mechanism during which a close proximity of persons to moving
mechanisms is necessary, may only be performed by persons that are informed about the hazard
and have perfect understanding of the principles of the mechanism's movement.
(3) GRASS CATCHER
During the process of opening or closing the grass catcher, there is a hazard of impact with or
compression of parts of the human body. When handling the grass catcher while dumping it out
or during repairs and adjustments, the person performing this task must always ensure that there
is no person or item located in the vicinity of the grass catcher that could be damaged by this
activity. It is forbidden to approach the grass catcher while it is being dumped out.
(4) MOVING AND HOT PARTS
When the engine is running, there are parts that are rotating and may cause serious injury to
various parts of the body. When performing maintenance or adjustment of mower parts located
underneath the hood or underneath the raised mower, it is thus necessary to pay increased
attention and never to bring any part of the body in the vicinity of moving parts. Only a person
with perfect knowledge of the principles of motion of these parts may perform their maintenance
and adjustment.
During operation, parts located under the hood heated up and when touched with an unprotected
part of the body may result in serious burns. Therefore, before opening the hood for the purpose
of performing maintenance or servicing tasks, always allow the mower to cool down and use
safety gloves for protection.
(5) DRIVER'S LOCATION
In the driver's location, there is a risk of falling from the platform or slipping as a result of
inattentiveness. Therefore, always be careful when getting on or getting off the mower.
Another hazard for the driver is fatigue, stress or erroneous behaviour caused by work overload,
insufficient illumination of the mowed area or noise during operation. It is, therefore, necessary to
always use hearing protection while using the mower, do not overload yourself and take breaks.
(6) FUEL TANK
The fuel in the fuel tank is a highly flammable substance the fumes of which are explosive. When
working with fuel or in the vicinity of the fuel tank (even when closed), never smoke, never come
close with an open flame or with items that generate high temperatures.
The above mentioned hazards are supplemented and expanded in the following chapters.
