7.6.2
Transportation To Or From Work Site
Before driving on the public highway check the following;
All parts of the flail mower are sufficiently clear of the tyres to prevent contact during bounce and sway
on braking, turning and undulating ground.
Ensure sufficient ballast is added to the front of the tractor to maintain steerage under bounce
conditions.
Ensure that the axle loads do not exceed the plated axle limits for the tractor
Ensure the tyres are correctly inflated and rated for the axle loads.
Ensure all stop, tail and indicator lights are in working order are visible to road users at the rear and fit
a trailer bar if appropriate.
Ensure that any debris; cut material, mud or stones that may have collected on the machine during
work are removed before driving on the public highway. This will prevent any hazard to other road
users being dropped onto the road.
IMPORTANT:
When transporting on the highway, it is the responsibility of the operator to obey all
relevant local highway laws.
IMPORTANT:
Pay due care and attention to the driving conditions and drive accordingly.
DO NOT
travel too quickly over undulating ground. The flail head is a significant mass, thus braking,
turning, sway and bounce can magnify forces and induce significant and damaging loads into
the flail mower which is rigidly attached to the tractor. Spearhead will not warrant damage
bought about by abuse of the machines intended use or neglectful handling.

Cutting Guidelines
7.7.1
The Tractor
Keep the tractor PTO speed at the indicated rpm in order to maintain the correct rotor speed for the job (see
section 1.4
‘Machine general specification’). Depending on the build of the fitted cutting unit this will be 2000 to
2200 rpm. Slower speeds may reduce the quality of cut obtained by the rotor.
7.7.2
The Work Area
Examine the piece of work to be cut. It is very important that the work site is inspected before cutting
and all hidden obstructions removed, or their position clearly marked so that they may be avoided.
Check for tree stumps, drain pipes, large stones, wire etc.
Repeated stalling of the rotor in heavy growth is likely to cause damage to the rotor.
WARNING!
Do not allow personnel near the machine while it is operating.
7.7.3
General Cutting Hints
The rotor shaft speed should ideally be between 2000 - 2200rpm.
Run the rotor using the indicated PTO speed.
Avoid rushing into the work. Remember that the unit must chop up the material as well as cut it to
height.
Avoid taking in too much grass by regulating the forward speed of the tractor.
If the rotor shaft slows down or begins to choke up in grass, raise the cutting unit a little and allow
grass to fall clear.
Before continuing with the cut let the rotor speed recover again.
Advantage may be gained in exceptional conditions by taking a narrow cut with part of the cutting unit
clear of the work.
IMPORTANT
: After the initial first 2 hours of work with a new machine, nuts and bolts should be checked
for tightness and the drive belts inspected and re-tensioned if required
