Precautions when driving
Tractor handling, stability, performance and braking efficiency are all affected by weight distribution, trailed or mounted implements, additional ballast and driving conditions. It is therefore of great importance that the operator exercises caution in every given situation.
Groundspeed must be adapted to ground conditions as well as to roads and paths. Always avoid abrupt change s of direction.
Be particularly cautious when turning corners, paying attention to machine overhang, length, height and weight.
Never use a narrow track tractor on very uneven or steeply sloping ground.
Never leave the tractor seat while the machine is operating.
Carrying people or animals on the machine when working or in transport is strictly forbidden.

Gross weight and weight per axle
The drawings are not legally binding, their only aim is to illustrate the method to use.
Prior to driving on public roads, check that criteria a re met to be in conformity with th e countrie's regulations:
- When coupling a tool to the front and rear 3-point lift linkage, the maximum authorized payload must not be exceeded.
- When coupling tools to the front and rear 3-point lift linkages, the maximum load on each axle's tires must not be exceeded.
- The load on the tractor front axle must always represent 20 % of the tracto r unladen weight.
For machines with hoppers or tanks:
- If the total unit weight exceeds the tractor Gross Combined Weight Rating in accordance with the countrie's legislation, empty the hopper to travel on public roads.
- In any case, we recommend to travel on public roads with empty hoppers and tanks.

Stage 1:
To measure:
- Tractor tare (T).
Gyrorake
Stage 2:
- Couple the machine to the tractor.
To measure:
- Load on front axle (t1):
• Tractor + machine (transport position).
To do:
- If the front axle load (t1) is below 20% of the tractor tare (T), add ballast weights (M1) to exceed the minimum load on the front axle.
Example:
• (T) = 7500 Kg (16535 lb)
• The front axle load must be of minimum 1500 Kg
(3300 lb).(20% of T)
• (t1) = 700 Kg (1545 lb).
• 700 Kg (1545 lb) < 1500 Kg (3300 lb).
• Add ballast weights until the minimum front axle
load is exceeded.
• Repeat checking procedure.

Stage 3:
To measure:
- Total weight (t):
• Tractor + machine (transport position).
• Ballast weights. Checking: To go to the next stage:
- Check in the tractor's operator's manual that the value measured is below the tractor's Gross Combined Weight Rating.
To do:
- If t < PTAC go to the next stage.
- If the total unit weight exceeds the tractor Gross Combined Weight Rating in accordance with the countrie's legislation, empty the hopper to travel on public roads.
Example:
• (t) = 10000 Kg (24250 lb)
• PTAC = 13000 Kg .
• t < PTAC : Go to the next stage.
