WARNING!
Failure to have sufficient load over the front axle or to drive at inappropriate speeds on undulating
terrain may result in a loss of directional control.
WARNING!
Transport the machine only at safe speeds. Serious accidents and injuries can result from
operating this equipment at unsafe speeds
WARNING!
Always ensure the tractor front end weight is sufficient to give proper front wheel contact and safe
steering when machine is raised on tractor hydraulics.
CAUTION! In transport, reduce speed, especially on bumpy roads.
IMPORTANT:
When transporting on the highway, it is the responsibility of the operator to obey all relevant local
highway laws.
2.9
Working on inclined ground
The ballast instructions in section 2.8 are sufficient for level ground operation.
Be aware that when working on inclined ground changes in the tractor centre of gravity can adversely affect the overall
stability.
There is naturally a limit to a safe amount of ballast compensation that can be applied for a given tractor unit and a
given incline. If compensating ballast is applied and the compensated axle must be driven on the public highway to
reach the work site the operator should ensure that the plated axle load is not exceeded.
Remember, a mower represents a significant mass which can generate a significant amount of inertia when moved at
speed. Stopping this inertia suddenly can induce overturning reactions.
DANGER!
When working on inclined ground avoid any high speed hydraulic manoeuvres which could cause
overturning.
2.10 Working on embankments
Sudden potholes at speed can quickly cause the tractor to change direction. At the same time the weight of the
implement may try to lift the front axle. This is a potentially lethal combination when working along narrow
embankments or dykes and can lead to overturning and potential drowning.
When working on top of embankments it is very important to have sufficient forward stability to ensure rapid steerage
control. Spearhead recommend 20% forward stability. This means that at least 20% of the total vehicle weight is
acting on the steering axle under normal level conditions.
DANGER!
When working on raised embankments ensure sufficient weight is on the steering wheels.
