Session 3 - Storing machinery after use
Session 1
Preparing the Tractor and Work Area for Maintenance
Preparing the Tractor and Work Area for Maintenance
Tractors start deteriorating immediately after manufacturing. In
order to reduce the speed of deterioration and wear you need to
carry our routine maintenance of the key systems of the tractor.
Tractor Service Intervals
Most tractor manufacturers will set service intervals - what
maintenance is required at what time interval.
As opposed to cars where the interval may be every 12 months or
10000 miles, the tractor intervals will be set by the number of
working hours.
What are the Consequences of Poor Maintenance?
Poor maintenance of the lubrication system will cause the components
to overheat, increase the wear of the components and increase the
likelihood of a breakdown.
What are the Consequences of Poor Maintenance?
Poor maintenance of the fuel system, if the filters are not
maintained, then there will be a build up of material on the filters
which may inhibit the flow of the fuel and the performance of the
tractor.
Fuel injectors can be affected by wear and dirt build up which
affect the performance of the engine.
What are the Consequences of Poor Maintenance?
Poor maintenance of the air cleaners can cause a choking effect
on the engine and result in power reduction.
What are the Consequences of Poor Maintenance?
Poor maintenance of the cooling systems will result in engine
overheating which will increase wear of the components.
If antifreeze levels are not maintained this could result in
serious damage due to frost.
Scaling within the cooling system can also result in overheating
problems.
What are the Consequences of Poor Maintenance?
Poor maintenance of the battery can result in failure to
maintain charge and therefore failure to start the tractor.
What are the Consequences of Poor Maintenance?
Poor maintenance of the brakes can result in loss of control and
serious accidents.
What are the Consequences of Poor Maintenance?
Poor maintenance of the transmission fluid levels can result in
transmission failure and expensive workshop bills.
What are the Consequences of Poor Maintenance?
Poor maintenance will also result in down time for the tractor
which most farms can not afford as usually these things go wrong
in the middle of a busy harvest season.
It is essential that a schedule of maintenance is followed
according to the manufacturer’s operating manual.

300 hours
Carry out 10 and 50 hour maintenance tasks and:
Drain the oil from the engine when it is hot
Renew filter element and re-fill the sump with fresh oil
Clean crankcase breather
Check steering box oil level where applicable and top up
300 hours
Make sure the clutch pedal free play is correctly adjusted on
tractors with a mechanical clutch linkage
Check brakes for adjustment
Drain water collected in the diesel fuel filter trap
Check fan belt tension
Make sure the radiator core is clean externally. Remove chaff
and dust with an airline or hosepipe
600 hours
In addition to all the tasks listed for 10, 50 and 300 hours:
Renew the diesel fuel filter element and bleed the system
Arrange for the diesel injectors to be checked and replaced if
necessary
Change the oil in the transmission system
Preparing the Tractor and Work Area for Maintenance
Clean off the tractor with a water pressure washer.
You should wear protective clothing - waterproof suit and
footwear (steel-toe capped safety boots), a mask and safety
glasses.
Particles of dirt can be blown into your eyes.
Gloves should also be worn to protect contaminants entering your
body through your skin – oils and greases.
Preparing the Tractor and Work Area for Maintenance
The tractor needs to be stable during maintenance.
Make sure the hand brake is on and the wheels are chocked.
Take the key out of the tractor.
The work area should be clean and free from hazards such as oil
spills.
Working on the Tractor
There should be a minimum of 2m available around the tractor for
the work to be carried out safely.
If any lubricants, oils or fuel need to be replaced or drained,
you will need to be aware of the hazards these bring to the
workshop.
Wear PPE, overalls, safety boots, latex gloves etc.
Hazardous Chemicals and Substances
Dealing with hazardous chemicals and substances: e.g. storage
and disposal in accordance with COSHH regulations.
When using and dealing with any hazardous chemicals or
substances there are key issues you need to be aware of:
Information on the hazardous substances.
How they can affect you.
Are they flammable/irritant/toxic etc.
Safety Data Sheet
You can get the information on any substance from the Safety
Data Sheet for the substance.
This will state the effects of the substance if contamination
takes place.
It will also highlight environmental considerations when dealing
with spills and disposal of waste.
Flammable Substances
In accordance to the COSHH regulations all flammable substances
should be stored in fire resistant lockable containers,
preferably outside the workshop area.
Chemicals
Any chemicals should be stored in a lockable chemical store, the
store should be insulated to maintain temperature(some chemicals
may respond to temperature changes).
The store should be designed to prevent spills from escaping
into the environment. The stores should be built with fire
resistant materials.
Disposal of Waste Materials
Any waste materials should be disposed of by a licensed
contractor –
Empty containers
Waste oils
Greases
Batteries
Tyres
Correct Procedures for Carrying Out Routine and Non Routine
Maintenance
Substances can pass into the body by four main ways:
Ingestion - swallowing
Inhalation – through the nose or mouth
Absorption – through the skin or in through open wounds
Eye contact – directly or by wiping your eyes with contaminated
hand/glove
Hazards in the Workshop
When working in the workshop you will come in contact with
materials and substances which can affect your health and
safety.
Many different substances are used which can enter your body in
different ways.
A variety of personal protective equipment is required to
minimise these risks.
Risk assessments should identify what is required.
Personal Protective Equipment for Tractor Mechanics
Steel toe-capped safety boots – these will protect your feet
from falling tools and materials, these should also have good
grip to avoid slips and falls.
Personal Protective Equipment for Tractor Mechanics
Coveralls
These should be supplied to protect your own clothes being
contaminated by oils, detergents, thinners, paints and dusts.
You should remove these when leaving the workshop and these
should be washed and returned to you cleaned.
Personal Protective Equipment for Tractor Mechanics
Ear Defenders
When a tractor is running within the workshop or activities like
grinding, will induce high noise levels.
Personal Protective Equipment for Tractor Mechanics
Respirators may be required when removing dust from machinery or
working on dusty machines like combine harvesters or hay balers.
You may be using substances that give off fumes which will also
require respirators to be used, where ventilation is inadequate.
Personal Protective Equipment for Tractor Mechanics
Gloves should be worn when handling substances like oil, petrol,
diesel or greases and many other substances to ensure that the
substances do not pass into your body through the skin.
Specialist gloves are required for hot work like welding or
soldering.
Personal Protective Equipment for Tractor Mechanics
Safety glasses should be worn to protect your eyes from dust
particles when working on or under machines and when using
grinders or drills. A welding face shield is always required to
protect eyes from bright light and sparks.
Personal Protective Equipment for Tractor Mechanics
Health and Safety at Work Act 1974
It is the employer’s responsibility to supply suitable PPE and
train the employees to use it. It is the employees duty to use
it correctly.
Session 3
Storing Machinery and Tools After Use
Storing Machinery and Tools After Use
Always put materials and tools away after use.
Never:
Leave power tools plugged in
Leave leads trailed along the floor or workbench
Leave hand tools on the floor of the workshop or tractor cab
floor
Leave spills on the floor
Storage of Tools
All hand tools should be placed in tool boxes, shelving or
hanging on tool racks.
Power tools should be checked for damage after use and replaced
on the workbench or shelving.
All materials (i.e.) parts, lubricants should be stored in
designated storage areas.
