byincorrectlyconguredballastoffset.
Incorrectly congured or absent ballast offset may negatively affect the steering, braking
and stability of the tractor.
• The tractor/implement combination must never be used without the calculated front or
rear ballasting.
See the Appendix for the calculation formulas.
• Never use the tractor/implement combination if the weight or axle load exceeds the
permitted values for the tractor or tyres.
1.13 Safety instructions - Travelling by road / transport
WARNING
Risk of accident while transporting the implement by road.
• Pay attention to national laws and regulations on the use of public highways.
• Ensure that the lights on your implement are in an excellent condition.
