Control Description

STARTER KEY SWITCH
The starter key (A) should be turned clockwise to
the 'pre-heat' (No. 2) position to heat the glowplugs
when the green warning lamp goes out, on warning
lamp display module, turn the starter key clockwise
to the 'start' (No. 3) position to start the engine.
After starting, the key should be released and
allowed to return automatically to the 'on' (No. 1)
position for normal running.
THROTTLE CONTROL LEVER
The lever (B) should be moved away from the
operator to increase the engine speed and
towards the operator to decrease the engine
speed.
NOTE: Engine should be used at full speed.
STEERING WHEEL RAKE ADJUSTMENT
The steering wheel is adjustable for rake. The
clamping release knob (A) is situated on the
side of the control console on the left hand
side. To adjust turn the clamping knob
anticlockwise to release and pivot the steering
wheel backwards and forwards to obtain
desired setting then lock in position by turning
clamping knob clockwise.
TRACTION FOOT PEDAL
To move the machine forward press the front
of the foot pedal (A). To reverse depress the
rear of the foot pedal. When the pedal is
released it will return to its neutral position.
SPEED LIMITER
The speed limiter (B) is operated by sliding the
black knob to the right or left. When slid to the
right the machine is limited to cutting speed,
when slid to the left, transport speed is
available. In transport mode, reverse is not
available.
IMPORTANT: To enable mow engage the speed limiter must be
in the cutting speed position. If cutting units are rotating,
moving the speed limiter between the mow and transport
positions will engage and disengage cylinder rotation.

TRANSPORT LATCHES
When transporting the machine ensure the
cutting decks are raised and the transport
latches (A) are engaged.
PARKING BRAKE
The parking brake (B) is engaged when the
lever is moved toward the operator. The brake
is fitted with a micro switch that senses brake
position. The brake must be applied to start
the machine, and when stopping and leaving
the seat.
CAUTION:- The parking brake must not
be applied whilst the vehicle is moving
DIFF LOCK CONTROL
The Diff lock (A) is operated by depressing the
foot switch. When the foot switch is released
the Diff Lock ceases to operate. The Diff Lock
should only be used in severe situations, and
should never be used on Tarmac or whilst
steering

HYDRAULIC LIFT LEVERS
The cutting units can be raised and lowered
by three control levers (A,B,C) situated on
the right hand side of the operators seat
and can be operated as follows:
Centre lever controls Centre Cutting Deck.
(B)
Right hand lever controls R.H. Cutting
Deck. (C)
Left hand lever controls L.H. Cutting Deck.
(A)
NOTE: If any unit is raised out of work then
lowered into work again the cylinder will not
rotate until the mow foot switch is depressed.
To lift: Move the lever(s) backwards and hold
in position until the units are at the required
height.
Tolower:Movethelever(s)fullyforwardsand
release, the unit(s) will lower to ground level.
DO NOT hold lever in forward position.
NOTE: The units will only lift and lower when
the engine is running.
IMPORTANT: If, when cutting, a lift control
lever is accidentally pulled back, the cutting
units will not float over ground undulations
until the lever is pushed fully forward and
allowed to return to neutral again.
CUTTING UNIT SWITCHES
To commence cutting ensure speed limiter
is in mow position and the units have been
lowered. Push bottom of the rocker switch
(G) and depress foot switch (A) Push top of
rocker switch to stop cutter unit rotation.
(Cutting unit stop rotating automatically
when raised.)

INSTRUMENT PANEL
A. ENGINE PREHEAT INDICATOR
LAMP
Colour green, on when the ignition switch is
turned clockwise to the pre-heat position.
Once the lamp goes out the engine can be
started.
B. ENGINE TEMPERATURE GAUGE
Indicates current temperature of engine,
whilst running.
C. HYDRAULIC OIL WARNING LAMP
Colour red, on when the hydraulic oil
temperature reaches a preset level. If the

on, and will go out once the engine has
started. If the light comes on while the
engine is running - STOP IMMEDIATELY as
this indicates that the engine oil pressure is
too low. Check the level of oil in the sump
and top up as necessary. Check the oil
pressure sender switch. Continued
operation may cause extensive damage to
the engine.
F. FUEL GAUGE
Located to the left of the engine temperature
gauge. Monitors fuel level.
G: PTO SWITCH
To commence cutting ensure the decks have
been lowered Push bottom of the rocker
switch (A) and depress foot switch. Push top
of rocker switch to stop cutter unit rotation.
(Cutting units stop rotating automatically
when raised.)
H: HEADLIGHT SWITCH
(Optional equipment )-Push switch half way
for running lights. Push down fully for
headlights

HORN
The horn is an audible alarm for the following
situations:
a) Horn (A) sounds continuously-this
indicates a high engine coolant
temperature condition. If this occurs, turn
off the engine immediately and resolve the
problem.
b) Horn (A) sounds intermittently-this
indicates a low engine oil pressure
condition. If this occurs, turn off the engine
immediately and resolve the problem.
BONNET RELEASE KEY

HEIGHT OF CUT
ADJUSTMENT
The cutting height is determined by the
position of the blades in relation to the caster
wheels. Changes to this height are made at
(4) points and can be made in any order. Make
adjustment selections for each deck from the
height of cut chart for that deck included in this
section.
NOTES
Cutting height must be set the same for all
three decks. The actual height may vary
slightly from the chart value because of tyre
pressure or condition.

7. Place pin Pinto the proper hole of
bracket for the selected height of
cut. CENTER DECK HEIGHT OF CUT CHART

HEIGHT OF CUT
ADJUSTMENT
