3.4 - Ballasting Requirements
Before transportation on public roads the tractor must not be overloaded and meet the
requirements laid out in section 3.3 to be suitable for this implement. The load bearing capacity of
the tyres, maximum permissible weights and axle loads must not be exceeded when the implement
is hitched or mounted to the tractor. The front axle must be loaded with at least 20% of the curb
weight to maintain sufficient steering capabilities.
Due to the differing variants, equipment specifications and modular nature of the equipment the
implement should be weighed separately to determine its weight prior to the calculations below
being undertaken.
