    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.

    blocked air filters

    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.

  • tractor being serviced

    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.
  • tractor being hosed down

    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.
  • person using spanner on tractor wearing gloves

    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.
  • person working on tractor

    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.
  • stock photo of oil drops

    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.
  • safety data sheet

    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.
  • warning signs: No unauthorised person beyond this point & Chemical store keep out

    Disposal of Waste Materials

    Any waste materials should be disposed of by a licensed contractor –

  • Empty containers
  • Waste oils
  • Greases
  • Batteries
  • Tyres
  • waste material being disposed

    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
  • close up of a face

    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.

    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.

    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.

    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.

    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
  • stock photo of oil being spilled

    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.
