Ballasting
⚠
WARNING
Serious injury due to the machine falling over!
When working with the front loader without rear counterweights, the tractor can tip over and cause injury
to the driver and persons in the surroundings. Moreover, there is the risk of overloading the front axle
of the tractor.
For front loader work, always use sufficient counterweight at the rear of the tractor.
The proper ballasting of the tractor is very
important to achieve sufficient stability. This
stability is influenced by the centre of gravity of
the loaded tractor / front loader combination, the
geometrical conditions, the weight, the
arrangement of the implement and the load in the
implement, the track width and wheel base of the
tractor, acceleration and braking processes as
well as the road conditions, to name a few.
A significant measure to increase the stability is
the addition of counterweights or rear weights,
which is strongly recommended for all front
loader work. If operation with a rear weight is not
possible, the stability can be increased with
appropriate ballasting on the rear wheels (wheel
weights) or with liquid in the tyres.
To determine the require weight for ballasting, the
following conditions apply:
When the front loader is fully loaded with the
implement in the most forward position, the rear
axle must carry min. 20 % of the total weight (sum
of the weight of the tractor, the front loader, the
implement, the load and the counterweight)
(see
). This ensures stability and braking
efficacy.
When the front loader is raised without an
implement, the front axle must carry min. 20 % of
the total weight (see
). This ensures the
steering capacity while driving.
Observe the operating instructions of the
tractor as well as the permissible axle loads
for the front and rear axles.
