4.2.5 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 changes 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
Description of symbols
The drawings are not legally binding, their only aim is to illustrate the method to use.
Prior to driving on public roads, check that all criteria are met to be in conformity with the
countrie's regulations:
• When coupling a tool to the front and/or rear 3-point lift linkage, the maximum authorized
payload must not be exceeded.
• When coupling tools to the front and/or rear 3-point lift linkages, the maximum load on
tractor's tires must not be exceeded.
• The load on the tractor front axle must always represent 20 % of the tractor 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 2:
To measure:
- Tractor tare (T).
T = _____kg
- 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.
