©Copyright KUHN S.A.

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.
Drive speed 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.
Precautions when driving on public roads

Stability of the tractor-spreader unit (Appendix A EN 14017)
Introduction
The example refers to a solid fertilizer spreader mounted on a tractor.
Due to the machine's mass and products
contained in the hopper, the tractor - spreader
unit can become unstable. In order to check the
total stability, the following relation can be applied to calculate the minimum ballasting at the front IF, min ,
which enables obtaining a weight on the front axle equal to 20 % of the tractor's tare:
The calculation takes into account the rear mounted equipment and the front - rear combinations.
