Card 05.17 Tractor

 

THE RISK:

  • Overturning or rearing up (due to lack of towing weight respect; ground subsidence; slipping; breaking etc)
  • Catching and dragging (by moving transmission devices)
  • Musculoskeletal pains (repetitive truck use and vibrations)
  • Hearing damages (use of noisy machines)
  • Balance loss (tyre blow-out; pneumatic escape from the rim and track break)
  • Crushing (while coupling and separating towed machines)
  • Bumps, collisions and running down people (during manoeuvres and circulation in the farm or on public roads)
  • Slipping and falling while climbing on/going out the vehicle (lacking in entering systems; mud; crop and oil remains on steps)
  • High temperature pressured fluids contact (break/explosion hydraulic pipe)
  • Fire (flammable fluids and failure in electric contacts)
  • Burns (contact with hot surfaces)

 

PRACTICAL AND OPERATING INDICATIONS:

 

It is necessary to check always, especially on tractors with foldable protection bar, if the bar is positioned and locked in a safe position.

 

The operator shall always use and fasten safety belt.

 

It is necessary to use always adequate weight if leaving the machine on a slope.

 

The operator shall be extremely careful on sloping ground.

The overturning risks is reduced if the following precautions are observed:

  • work with the vertical ploughing technique (called “rittochino”) along the line of steepest descent;
  • proceeding with the equipment pointing upwards;
  • choose adequate power according to the equipment used;
  • choose adequate gear;
  • do not run with the engine put into neutral (that is do not use inertia due to the natural slope of the ground).

 

In order to avoid catching and dragging risks, the operator shall keep away from motion transmission device and the propeller shaft. He/she can go by these devices only when the engine is not running and the machine has stopped.

 

It is necessary to use always transmission complete with protections and wear adequate clothing, avoiding fluttering parts.

 

Right use and adequate maintenance help minimizing risks and containing vibrations.

 

It is necessary to adopt technical and organising measures to protect operators against noise:

  • on the source (noise control at its source);
  • on diffusion (collective measures such as work organisation, reduction of noise transmission);
  • on operators (DPI for ears).

 

Operator shall avoid waiting in the coupling zone of the tractor-operating machine (sudden movements and hazardous crushing may occur).

 

It is necessary to use suitable ways of access and support handles.

 

Operator shall wear anti-skid shoes.

 

Operator shall not go by vehicles during coupling manoeuvres, helped by ground staff, between tractor and operating machine until they are still.

 

It is advisable to couple and separate any tool only on even ground and after having used the handbrake.

 

The ladder leading to the tractor driver’s seat shall be free from any mud or oil remains and be provided with a protection preventing the foot to slip towards the wheel.

 

Handrail and handles shall always provide three contact points to the operator.

 

The driver shall not let any other operator on the tractor if it is not allowed by the road worthiness certificate and if there is not the passenger seat.

 

The driver shall switch off the engine when he/she get off the tractor to set or separate towed machines.

 

The driver shall not leave the machine unattended with the keys in the ignition panel.

Remember that even in the case of agricultural or forestry tractors with load floor (motion agricultural over 400 kg), is mandatory installation of devices protection in the event of reversal (arc protection / roll-bar) and seat belt.

 

FURTHER INDICATIONS AND ADVICE

  • It is necessary to check the tyres wear and tear and substitute them if worn out.
  • It is necessary to set the track in the largest position in order to adapt it to the work the operator is about to carry out.
  • It is necessary to avoid sharp brake. It is advisable to keep coupled brake pedals in perfect efficiency to avoid hazardous skidding.
  • The operator shall be extremely careful next to ditches, ramps and uneven ground.
  • It is forbidden to operate the tractor at high speed, in particular on bends.
  • It is advisable to slow down while turning on sloping ground.
  • If the tractor is provided with a front loader, the operator shall keep the bucket and the load as low as possible. While crossing a slope, the operator shall keep the equipment lifted as low as possible to avoid touching the ground.
  • While running on a sloping ground with mounted lateral equipment, it is necessary to keep it pointing downwards.
  • The operator shall keep low gear in descent. The tractor shall not run with the engine put into neutral or with the clutch disengaged.
  • The operator shall be extremely careful on uneven ground to avoid losing control of the tractor.
  • The operator shall not have a too heavy load on tow: the tractor may rear up and rotate on the towed load putting itself in a “knife blade” position.
  • If possible, the operator shall avoid to cross sloping ground or steep hills. If it is compulsory, then the operator shall watch out for holes, hollows and ground projections. He/she shall avoid overcoming trunks, stones and lifted zones.
  • If it is necessary to cross a steep hill, the operator shall avoid sharp brakes,he/she shall slow down and take a long turn.
  • Avoid ditches, banks, embankments and rivers and channel banks. Keep away from edges which may subside.
  • The operator shall start the tractor slowly and then increasing speed gradually. It is forbidden to increase the numbers of revolutions and use clutch to boost traction. If the tractor is coupled to a heavy load, an improper use of the clutch may provoke overturning.
  • If a tractor is caught in mud or blocked in the ground, mounted equipment shall be lifted and the operator shall try to rear or go ahead locking the differential gear. If it is not possible, another vehicle shall tow the tractor.
  • If a tractor is dragging a heavy equipment in the rear, the operator shall move in reverse to climb a slope and moving ahead to descent. The equipment shall be kept as low as possible.
  • If the operator is working in isolated areas, on the tractor there shall be a powder extinguisher and a medipack. If it is possible, workers shall not operate alone.
