SAFETY INTERLOCK SWITCHES
The machine is fitted with a number of interlock
switches to give additional safety to the customer.
Here are some tips relating to the use of the
switches:-
Before the operator dismounts, the following must be
effected:
Engage the Parking Brake ‘H’, Fig. 5
Select neutral on Drive Pedal ‘F’, Fig. 5
Disengage Cylinder Drive (lever) ‘G’, Fig. 5
If all the above criteria are met the operator may
dismount with the engine still running however if any
of the above criteria are omitted the engine will stop.
The engine will also stop if the operator tries to
engage drive with the Parking Brake still engaged.
TO START THE ENGINE
Set the Throttle Control ‘I’. Fig. 6 to the choke position
for cold start (midway through speed range for warm
engine). Turn the key ‘J’, Fig. 6 clockwise until
resistance is felt and then turn fully to operate the
starter.
When the engine starts, release the key. With the
engine running cold, allow it to warm up and then
move the Throttle Control ‘I’from the choke position
to fast run.
TO STOP THE ENGINE
Operate the Throttle Control ‘I’ to the “slow run”
position and turn the Ignition Switch ‘J’, Fig. 6 anti-
clockwise until the engine stops.
STEERING
The rear wheel steering is operated by a drag link
from the steering wheel giving complete
manoeuvrability.
Become familiar with machine handling before
attempting higher speeds or difficult manoeuvres.
WORKING INSTRUCTIONS
With the engine running at full speed, the machine
may be used in either travelling or cutting mode. If
travelling, ensure that all the cylinders are lifted and
latched ‘K’, Fig. 1 and ‘L’, Fig. 7 into the travelling
position and that
the Cylinder Drive (lever) ‘G’, Fig. 5 is
disengaged.
Release the Parking Brake ‘H’, Fig. 6 and
depress the Drive Pedal ‘F’, Fig. 6. The pedal is
not an accelerator but controls the movement of
the machine while not altering the engine speed.
To move forward, depress the front of the pedal.
The further the pedal is pressed the faster the
machine will go. To select neutral, simply bring
the pedal to the central rest position to which it
will automatically return. To select reverse
depress the rear of the pedal.
CUTTING WITH THE MACHINE
The Trooper is designed to have all three
cylinders operating at the same time. There is no
method of disconnecting separate cylinders,
therefore all cylinders must be lowered from the
transport position on to the grass. With the
engine running at half speed, engage Cylinder
Drive (level) ‘G’, Fig. 6 by pulling the left-hand
lever up and locking it in the raised position on
the left latch plate. When all the cylinders are
revolving, the Throttle ‘I’ should then be set to
full speed.
Depress the Drive Pedal ‘F’to select the
required forward speed. The length of grass will
determine the height of cut and the forward
speed.
If the grass is long, 3 to 4 inches (76 to 102mm)
then the cylinders will need to be set fairly high
(adjustment is available from ½in to 2½in [12mm
to 64mm]) and a low forward speed selected.
If the grass is short then a lower height setting
can be used and a faster forward speed may be
selected. Full speed should only be used when
the cutters are disengaged and are in the
transport position and only when a clear straight
run is available.
The Throttle ‘I’should be set at maximum to
allow the engine to run at its governed speed.
Never allow the engine to labour, ease off the
Drive Pedal ‘F’to slow the forward speed or alter
the height of cut.
CYLINDER DRIVE CLUTCH
The Cylinder Drive (lever) ‘G’, Fig. 5 situated on
the forward left hand side of the central seat
mounting box, is the cutter drive clutch lever and
this controls the drive to all cutter
