2.8
Working On Inclined Ground
The ballast instructions in Section 2.7 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. As the attachment is extended with the reach arm deployed downhill additional ballast will be
required on the rear offside wheel to compensate.
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 reach arm with machine attachment 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 high speed hydraulic movements which could cause
overturning.
2.9
Working On Embankments
Sudden potholes at speed can quickly cause the tractor to change direction. At the same time the weight of the
attachments 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.
2.10 Attachment And Removal From The Reach Arm
DANGER!
Always follow the ma
nufacturer’s instructions for attachment and removal of the machine
from the tractor.
DANGER!
Always disengage the machine, kill the tractor engine, remove and pocket the key before
dismounting for any reason.
DANGER!
Always ensure when you remove your machine from the tractor that it is left in a safe and
stable position using the stands and props provided and secured.
DANGER!
Never operate the tractor or machine controls from any position other than from the driving
seat.
DANGER!
Never leave a machine unattended in a raised position
– it should be lowered to the ground in
a safe position on a level firm site.
DANGER!
Never leave a tractor with the key in or the engine running.
DANGER!
Ensure hydraulic pipes are carefully and correctly routed to avoid damage by chaffing,
stretching or pinching and that they are held in place with the correct fittings.
