Operation Of The Autopilot
To activate Autopilot first slew the head into work position and lower the head
horizontally onto the ground.
Remove the 2 transport pins. Raise the head 300 - 400mm off the ground and
ensure Auto slew is switched on, engage rotor drive and then switch on Autopilot.
The head will gently drop to the ground and be ready for work.
Your forward speed will be determined by ground conditions, density of growth,
height of cut and generally operating within a safety margin to allow you time to react
to any unexpected occurrence.
Once in work the Autopilot will control the head height and angle, allowing the head
to accurately follow all the ground contours. The operator will control reach whenever
necessary.
The Spearhead Autopilot will assist you with grass mowing. It does not relieve you of
your responsibility to drive with care and understanding for the machine.
When crossing “grips” or drainage gullies, it may be necessary to temporarily lift with
the main ram using hydraulic joystick and the red isolator button.
If you approach larger areas not to be mown i.e. road junction, bridges and crash
barriers, it will be necessary to switch off the Autopilot, enabling you to raise the head
from the ground.
Before switching on the Autopilot please ensure the head is within 300 - 400mm from
the ground. Always ensure that the Auto-break-back is switched on when operating
with the Autopilot.
Transport of the machines with Autopilot
1. Turn off autopilot switch (green)

Warning
Autopilot is not suitable in extreme conditions i.e. very steep banks and very
wet conditions. Always ensure the rear roller is n
ot “clogged” with mud.
If the machine starts to move uncontrolled, isolate by turning off the green
switch, place the head on the ground, follow point 4, 5 and 6 above. Turn off
the tractor, apply parking brake and remove the ignition key. Inspect machine for fault.
