general mounting and dismounting safety precautions
GENERAL MOUNTING AND DISMOUNTING SAFETY PRECAUTIONS
  • - face the tractor at all times.
  • - use the three point contact method.
  • - never mount or dismount a moving tractor.
  • - always use the designated hand holds and steps.
  • - never use control levers as a hand hold and do not step on foot controls when mounting and dismounting.
safety precautions cont
Safety Precautions cont:
  • - never mount or dismount a tractor from the rear.
  • - clean your shoes and wipe your hands before mounting.
  • - never jump off a tractor.
  • - remove any trash or obstructions on the steps or operator’s compartment before mounting.
mounting procedures
Mounting procedures:
  • 1. Clean shoes of any mud, oil or any other residue preventing firm contact with the steps.
  • 2. Be sure hands are free of any oil or other residue preventing a firm grip of hand holds.
  • 3. Face the tractor operator’s compartment and secure a firm grip with both hands.
mounting procedures cont
Mounting procedures cont:
  • 4. Place one foot on the first step, then while using both hands and foot to pull yourself up, place the other foot on the next step.
  • 5. With both feet firmly on the steps, move one hand to secure a second hold and then move the lowest foot on the steps to the next step. Repeat this procedure until you have both feet on the operator’s platform.
mounting procedures cont1
Mounting procedures cont:
  • 6. With both feet on the operator’s platform and a firm grip with both hands, turn and move one foot to the opposite side of the operator’s platform having the seat behind you.
  • 7. You can now sit in the operator’s seat, and lock the seat belt if the tractor is equipped with a ROPS.
procedures for dismounting a tractor are
Procedures for dismounting a tractor are:
  • 1. Unlock the seat belt, if provided, secure a firm grip with both hands and stand in front of the seat.
  • 2. While still maintaining a firm grip with both hands, move both feet to one side of the operator’s platform.
  • 3. Turn facing the operator’s compartment and while looking at the steps, place one foot on the top step, keeping a firm grip with both hands.
dismounting procedures cont
Dismounting Procedures cont.
  • 4. Obtain a new grip with one hand if necessary, then move the other foot down to the next step.
  • 5. Repeat step 4 until you have both feet firmly on the ground.
  • 6. Release both hand holds, turn facing away from the tractor and walk away.
controls
Controls
  • are devices (typically levers and switches) designed to give the operator a means of communication with the tractor and the ability to regulate and command the tractor to perform all desired responses. The controls are located within reach from the operator’s seat. Agricultural tractors have three basic type of controls.
control types
Control Types:
  • 1. Foot controls - these controls are operated by the operator’s feet.
  • 2. Hand controls - these controls are operated by the operator’s hands.
  • 3. Combination controls - these controls can be operated by the operator’s feet and/or hands. The most common is the engine speed control.
the nine basic controls common to all agricultural tractors are
The nine basic controls common to all agricultural tractors are:
  • 1. Brake control - this gives the operator control over stopping, turning, and parking.
  • 2. Clutch control - this allows the operator to engage or disengage power to moving parts of the tractor. A clutch control can be considered the go-no-go control. This includes: traction controls, combination traction and brake controls, PTO controls, and field implement controls.
basic controls cont
Basic Controls cont:
  • 3. Engine speed control (throttle)- this allows the operator to regulate the revolutions per minute (RPM’s) of the engine.
  • 4. Ground speed and directional controls (transmission gears)- these controls give the operator control over ground speed (how fast you are traveling) and direction (forward or reverse).
  • 5. Differential lock - this control locks together the rotation of the main drive wheels.Control types continued:
basic controls cont1
Basic Controls cont:
  • 6. Steering control - better known as the steering wheel - gives the operator the ability to turn right or left while moving in either a forward or reverse direction.
  • 7. Electrical controls - these controls are either on or off. Electrical controls activate accessories such as the engine starter and lights.
basic controls cont2
Basic Controls cont:
  • 8. Engine stop controls - on gasoline engines, it stops the spark going to the spark plugs; on some gasoline and all diesel engines, it shuts off the fuel to the engine. Stop controls can be either electrically or manually (push-pull) activated.
  • 9. Lift controls for implements or equipment - these are typically hand type controls and give the operator the ability to position or maneuver any attachments into a desired position.

NOTE:
  • To find out the specific types and the operation of controls on your tractor, read the operator’s manual.
instruments
Instruments
  • are the devices that allow the tractor to communicate with the operator and notify him/her of safe and/or unsafe conditions. Instruments may be in the form of a warning light, analog gauge, or digital display.
most common instruments used include
Most Common Instruments used include:
  • 1. Engine speed indicator (tachometer)- this indicator identifies the engine speed in revolutions per minute (RPM).
  • 2. Oil pressure indicator - the oil pressure indicator will either tell the operator the actual oil pressure or warn of low oil pressure during engine operation.
  • 3. Engine temperature indicator- the engine temperature indicator will either indicate actual operating temperature or notify the operator of an unsafe operating condition.
most common instruments cont
Most Common Instruments cont.
  • 4. Electrical system condition - this is commonly referred to as the battery condition indicator. However, it’s actual purpose is to indicate if the electrical charging system is supplying adequate voltage to maintain all electrical components while in operation.
  • 5. Miscellaneous instruments - some manufacturers include a variety of other instruments. Some additional indicators may include: fuel gauge, coolant level, air filter condition, transmission temperature, hydraulic oil level and many more.
operator symbols
Operator symbols
  • are visually recognized figures used to transmit information free of words of explanation (ASAE, 1995). The operator symbols are used to identify operator controls, instruments, and servicing locations and/or devices.
hand signals
Hand signals
  • are used when the operator is being assisted by another person. The hand signals become the method of communication between the operator and assistant when noise or distance prevents the use of normal voice communications.
safety signs
Safety signs
  • are a visual alerting device in the form of a decal, label, placard, or other marking such as an embossing, stamping, etching, or other process that advises the observer of the nature and degree of the potential hazard(s) that can cause injury or death. Safety signs can also provide safety precautions or evasive actions to take, or provide other directions to eliminate or reduce the hazard (ASAE).
three basic types of safety signs
Three basic types of Safety Signs:
  • DANGER - indicates a threatening hazardous situation that, if not avoided, will result in death or serious injury. The signal word “DANGER” is to be limited to the most extreme situations, typically for machine components that, for connection purposes, cannot be guarded (ASAE).
safety signs cont
Safety Signs cont.
  • WARNING - indicates a potentially hazardous situation that, if not avoided, could result in death or serious injury, and includes hazards that are exposed when guards are removed. The signal word “WARNING” may also be used to alert against unsafe practices (ASAE).
safety signs cont1
Safety Signs cont.
  • CAUTION- indicates a potentially hazardous situation that, if not avoided, may result in minor or moderate injury. The signal word “CAUTION” may also be used to alert against unsafe conditions (ASAE).
