TRANSMISSION OPERATION
Your tractor may be fitted with one of three
transmission options dependent on country and
specification.
12 x 12 Synchro Command
This transmission offers 12 forward and reverse
synchromesh gears selected by two shift levers
conveniently placed to the right of the driver. The
forward and reverse synchronised shuttle is
operated by a lever to the left of the steering column.
24 x 24 Dual Command
Operating in a similar manner to the 12 x 12, Dual
Command offers the additional benefit of a
hydraulically engaged underdrive for each of the
basic 12 gears. This provides 24 forward and reverse
ratios. Underdrive may be engaged on the move
without depressing the clutch pedal. A clutchless
shuttle function is also featured on the Dual
Command transmission.
16 x 16 (17 x 16) Electro Command
The Electro Command transmission has
4
powershift gears and four range gears providing 16
forward and reverse ratios. On 50 Km/h models, an
additional gear provides 17 forward ratios. When
operated simultaneously, the powershift and range
change buttons will provide clutchless changes on
the move through ratios 1--8 and 9--16 (17).

SECTION 2 -- CONTROLS, INSTRUMENTS AND OPERATION
12 x 12 SYNCHRO COMMAND TRANSMISSION
This transmission offers 12 gear ratios in forward and
reverse. Operation is by means of the main shift lever,
range lever and a forward/reverse shuttle lever.
An optional reduction gear set (creeper gears) offers
a further 8 ratios, forward and reverse.
IMPORTANT: Do not change gear or operate the
shuttle lever without depressing the clutch pedal.
Main Shift Lever
The main shift lever (1) operates in a conventional
H-pattern and, in conjunction with the clutch pedal,
is used to select any of four gear ratios, whether the
tractor is stationary or moving.
IMPORTANT: To avoid premature wear, do not use
the clutch pedal as a footrest.
Range Lever
The right-hand lever (2) is the range lever which, in
conjunction with the clutch pedal, is used to select
115
any one of three ranges (I -- the lowest speed range,
II-- medium range and III -- the highest speed range).
This has the effect of tripling the number of gears,
F

WARNING
116
To prevent inadvertent tractor movement, take care
to avoid accidental contact with the gearshift levers.
Always stop the engine, firmly apply the parking
brake and place all gear shift levers in neutral before
leaving the tractor.
2--67
SECTION 2 -- CONTROLS, INSTRUMENTS AND OPERATION
Shuttle Lever
The shuttle lever (1) is used to select forward or
reverse travel when any one of the twelve gears is
engaged, provided that the clutch pedal is
depressed. To reverse the direction of travel, reduce
engine and tractor speed to a minimum, depress the
clutch and move the shuttle lever rearwards. Re-
engage the clutch and increase engine speed, as
required.
NOTE: An interlock mechanism prevents movement
of the shuttle lever unless the clutch pedal is
depressed.The starting motor will not operate unless
117
the shuttle lever is in neutral and the clutch pedal is
depressed.
IMPORTANT: Fully depress the clutch pedal when
changing gear. Partially depressing the clutch pedal
when changing gear may result in damage to
transmission components. Also, when changing
down on the move, select the next consecutive gear
in order to avoid damage to the clutch and/or
overspeeding of the engine.
NOTE: When operating in temperatures below --18° C
(0° F) with cold transmission oil, avoid shuttle
operations, as far as practicable, until the oil has
warmed up.
Creeper Gears (where fitted)
For operations requiring extra low ground speeds,
reduction gear sets (creeper gears) are available.
As the name implies, the reduction gear set has the
effect of reducing all the ratios within the main
transmission to provide an additional twelve gears in
forward and reverse.
Creeper gear selection is denoted by the illumination
of the creeper gear symbol in the instrument panel.

SECTION 2 -- CONTROLS, INSTRUMENTS AND OPERATION
24 x 24 DUAL COMMAND TRANSMISSION
Dual Command transmission has an hydraulically
operated clutch pack allowing the operator to select
underdrive in any forward or reverse gear while on
the move. This effectively increases torque by 22%,
reduces tractor speed by approximately 18%.
An optional reduction gear set (creeper gears) offers
a further 8 ratios, forward and reverse.
Main Shift Lever
The main transmission lever (1) is provided with
electrical push buttons to actuate the Dual
Command function. Operation and function is
otherwise identical to the 12 x 12 transmission.
Underdrive is hydraulically engaged, the valve being
actuated by a solenoid controlled by push buttons (2)
and (3) on the main gear shift lever.
Press the lower switch (3) to engage Underdrive
(tortoise symbol). Press the upper switch (2) (hare
symbol) to disengage Dual Command and return to
119
direct drive.
When direct drive is engaged, the green indicator
light on the instrument panel, which has a ‘hare’
symbol, illuminates to indicate that Dual Command
is in direct drive.
IMPORTANT: A tractor with Dual Command
transmission must not be tow-started. See ‘Starting
the Tractor with Jump Leads’ in section 3.
WARNING
Always engage the parking brake before
dismounting from the tractor. Dual Command will not
prevent the tractor from rolling when the engine is
shut off.
WARNING
To prevent inadvertent tractor movement, take care
to avoid accidental contact with the gearshift levers.
Always stop the engine, firmly apply the parking
brake and place all gear shift levers in neutral before
leaving the tractor.
2--73
SECTION 2 -- CONTROLS, INSTRUMENTS AND OPERATION
Shuttle Lever
Selection of forward or reverse travel is by means of
an electrically operated shuttle lever, located to the
left of the steering wheel. The lever is spring-loaded
to prevent inadvertent movement, lift to select
forward or reverse drive. It is not necessary to
depress the clutch pedal when actuating the shuttle
lever.
To change from forward to reverse motion, apply the
brakes to slow the tractor, move the shuttle lever fully
rearward, and control tractor speed by means of the
throttle.
120
NOTE: Forward or reverse drive cannot be engaged
unless the operator is in the tractor seat. Additionally,
if the vehicle is moved in either direction with the
handbrake engaged, an audible alarm will be heard.
IMPORTANT: To reduce clutch damage caused by
shuttle shifting in too high a gear or at too high a
speed, a warning bleeper will be heard and the
symbol ‘N’ will flash in the instrument panel when
tractor speed is greater than 9 Km/h (5 MPH).
Auto Take Off
The Auto Take Off feature permits the operator to

2--74
SECTION 2 -- CONTROLS, INSTRUMENTS AND OPERATION
Creeper Gears (where fitted)
For operations requiring extra low ground speeds,
reduction gear sets (creeper gears) are available.
The reduction gear set has the effect of reducing all
the ratios within the main transmission to provide an
additional twenty four gears in forward and reverse.
The creeper gears are selected by means of a rocker
switch (1) located on the right-hand control console.
With the engine running, clutch depressed and the
shuttle lever in neutral, apply and hold down the
121
tractor footbrakes. Momentarily depress the lower
part of the selector switch (1), Figure 121, to engage
the creeper gears.
The creep speed symbol (1) Figure 122, will appear
in the Instrument panel.
To disengage creeper gears, repeat the above
procedure and depress the selector switch again.
The creep speed symbol will cease to illuminate.
IMPORTANT: The creeper gears offer very low
ground speeds. Do not use the low gearing
advantage to apply excessive draft loads to the
tractor.

SECTION 2 -- CONTROLS, INSTRUMENTS AND OPERATION
ELECTRO COMMAND TRANSMISSION
This transmission offers 16 or 17 forward, and 16
reverse ratios. An optional reduction gear set
(creeper gears) offers a further 16 ratios, forward and
reverse.
In the following text, operational information is based
on the 16 x 16 transmission (30 and 40 Km/h).
However, the
17 x 16 transmission
(50
Km/h)
functions in exactly the same way.
IMPORTANT: When travelling at high road speeds
with trailed or semi--mounted equipment attached to
the tractor, ensure the equipment is rated for 50K/mh
operation in respect to its construction, brakes and
tyres.
The transmission is controlled by means of a main
shift lever, two powershift buttons and a range
change button. A shuttle lever mounted to the left of
the steering wheel selects forward or reverse drive.
Transmission and throttle controls are colour-coded
orange.
This transmission provides four powershift gears in
each of the four intermediate ranges A (1--4), B
(5--8), C (9--12), and D (13--16). Clutchless shifts
between gears 4 and 5, 12 and 13 are made by using
the range button in conjunction with the powershift
buttons. Range shifts between Low and High (8th.
and 9th. gears), can only be made with the clutch
pedal fully depressed.
Main Shift Lever
The main shift lever (1), is used to select both range
gears and main gears. When selecting High or Low
ranges (moving the lever forwards or rearwards) the
123
clutch pedal must always be depressed.
With the shuttle lever in neutral and clutch pedal fully
depressed, move the main shift lever rearward into
the Low (field) range. In this range, powershift gears
1--4 or 5--8 can be selected. Move the lever fully
forward to select powershift gears 9--12 or 13--16 in
the High range. To engage neutral, move the lever to
the mid position.
2--84
SECTION 2 -- CONTROLS, INSTRUMENTS AND OPERATION
NOTE: With the tractor stationary and the shuttle
lever in forward or reverse drive, moving the main
shift lever from neutral without first depressing the
clutch pedal will result in the drive not being engaged.
Error code ‘N’ will appear in the transmission display
and an audible alarm will sound. Depress the clutch
pedal and shift the shuttle lever to neutral to clear the
display and re-engage the drive.
NOTE: To avoid power losses due to internal friction,
place both gearshift lever and the shuttle lever in
neutral when performing stationary operations.
124
The shift lever (1), incorporates two electrical push
buttons that are used to make instantaneous up or
down powershifts. Button (2) is depressed to make
upward changes, button (4) for downward changes.
It is not necessary to use the clutch pedal to make a
powershift.
For convenience, a duplicate set of shift buttons are
located on the right--hand control panel, see
Figure 126.
To make an upward change between gears 4 and 5
hold in the intermediate range change button (3) and
depress the upshift button (2),. The change will be
125
indicated in the gear display. Use the same
procedure to change from gear 12 to 13.
Downward changes are made using the same
procedure but depressing the downshift button (4).
If preferred, the clutch pedal may be used instead of
the intermediate range change button.
NOTE: Attempting to shift from one range to another
without using the range change button or clutch
pedal will cause the audible alarm to sound.
When the main shift lever is moved forward from
neutral or from any gear within the 1--8 range, 9th.
gear will always be selected.
Conversely, if the lever is moved rearward from
126
neutral or from the 9--16 range with the tractor
moving, the speed matching function will select the
most suitable gear between 5th and 8th. To select an
alternative gear, maintain pressure on the clutch
pedal and use the powershift buttons to engage a
different gear, then release the clutch pedal.

SECTION 2 -- CONTROLS, INSTRUMENTS AND OPERATION
Shuttle Lever
Selection of forward or reverse travel is by means of
an electrically operated shuttle lever (1), located to
the left of the steering wheel. The lever is
spring-loaded to prevent inadvertent movement, lift
toward the steering wheel before selecting forward or
reverse drive. It is not necessary to depress the
clutch pedal when operating the shuttle lever.
NOTE: Forward or reverse drive cannot be engaged
unless the operator is in the tractor seat. Additionally,
if the vehicle is moved in either direction with the
handbrake engaged, an audible alarm will be heard
127
and ’P’ will be displayed in the Dot Matrix and Digital
Gear Displays (where fitted).
NOTE: To avoid power losses due to internal friction,
place both gearshift lever and the shuttle lever in
neutral when performing stationary operations.
To reduce clutch damage caused by shuttle shifting
in too high a gear or at too high a speed, the tractor
will slow using engine braking and the transmission
will then downshift to the lowest gear within the
selected intermediate range before changing
direction.
Shuttle Mode
During normal shuttle operations the same gear is
used for both forward and reverse. However, if 13th
gear or above is selected, the shuttle gear will be 9th.
With Shuttle Mode selected, the electronic control
unit for the transmission is able to memorise shuttle
gear combinations within a range of gears. To
activate Shuttle Mode, carry out the following
procedure.
• With the key start off, move the shuttle lever to
the reverse position. Depress and hold the
transmission upshift button and turn the key start
on. Do not start the engine.
• The transmission symbol and DB H3 will appear
in the dot matrix display and the centre LCD will
show ’no’ or ’YES’. Release the upshift button.
•
’no’ indicates memory function is disabled, ’YES’
shows the memory function is activated.
• Use the upshift and downshift buttons to toggle
between ’no’ and ’YES’. With the appropriate
128
selection made, turn the key start off and return
the shuttle lever to neutral.
2--86
SECTION 2 -- CONTROLS, INSTRUMENTS AND OPERATION
Setting the Forward/Reverse Shuttle Gear
Start the engine and, with the clutch pedal
depressed, place the shuttle lever (1) in the forward
position. Do not release the clutch pedal. Using the
upshift/downshift buttons, set the forward gear.
Move the shuttle lever into reverse and repeat the
procedure to set the reverse gear. With the forward
and reverse gears set, return the shuttle lever to
neutral and release the clutch pedal. Shuttle Mode is
now activated.
NOTE: Selecting the shuttle gear with the lever in
neutral will result in the same ratio being set for both
129
forward and reverse.
WARNING
To prevent inadvertent tractor movement, always
stop the engine, place the shuttle lever in neutral and
firmly apply the parking brake before leaving the
tractor. The transmission will not prevent the tractor
from rolling when the engine is shut off.
Auto Take Off
The Auto Take Off feature permits the operator to
engage drive without using the clutch pedal by simply
moving the shuttle lever from neutral to the forward
or reverse position.
The Auto Take Off function is automatically enabled
under normal starting conditions. i.e. operator in the
driving seat, clutch pedal depressed, shuttle lever in
neutral.
After selecting the appropriate gear ranges with the
main shift lever simply move the shuttle lever to the
forward or reverse position without depressing the
130
clutch pedal. The Auto Take Off function will provide
a controlled start from rest.
NOTE: The Auto Take Off function will be disabled
if the vehicle is at rest with the shuttle lever in the
neutral position and the operator leaves the seat.
Should Auto Take Off be disabled for any reason, the
operator should carry out the following procedure to
re--enable this function.
While sitting in the seat, release the handbrake and
cycle the clutch pedal. The vehicle will then move off
in the direction selected on the shuttle lever.
Once enabled, the Auto Take Off function will
continue to function as long as the operator remains
in the seat.
2--87
SECTION 2 -- CONTROLS, INSTRUMENTS AND OPERATION
Gear Displays
Dependent upon tractor specification, two types of
gear display may be fitted.
LED Gear Display
An illuminated display (1), to the right of the main shift
lever indicates the gear selected.
As each gear is selected, the appropriate number (3)
will be illuminated in the display. With Auto Shift
engaged, the symbols for Active Road (2) and Active
Field (4) will also be illuminated. When changing the
Auto Shift point, symbol (5) will flash during the
programming procedure.
NOTE: Auto Shift is an option and may not be fitted
to your tractor.
131
Digital Gear Display
The digital display provides a comprehensive range
of information that includes:
Field and road Auto Shift (1) symbols.
Forward and reverse gears (2). The display
shows the current forward gear and the
corresponding reverse or ’shuttle’ gear.
Shuttle lever position. Forward, neutral and
reverse (3).
Gear span for each range (4).
132
Clutch Pedal
It is not necessary to use theclutch pedal(1) tomake
a powershift or when shuttle shifting
(changing
direction between forward and reverse). Use of the
clutch is recommended for positioning the tractor
when attaching equipment or operating in confined
spaces when the low gears are not slow enough, at
moderate/low engine speeds, to give precise control.
IMPORTANT: To avoid premature clutch wear, do
not use the clutch pedal as a footrest.
NOTE: There may be occasions when error codes
133
’N’ or ’CP’ flash in the Dot Matrix and Digital Gear
Displays (where fitted). Should this occur, move
shuttle lever to neutral (’N’) or cycle the clutch pedal
(’CP’) to clear the error.
2--88
SECTION 2 -- CONTROLS, INSTRUMENTS AND OPERATION
Driving the Tractor
With the main shift and shuttle levers in neutral,
depress the clutch pedal and start the engine.
NOTE: A neutral start switch prevents operation of
the starting motor unless the shuttle lever is in neutral
and the clutch pedal is depressed.
For forward travel, with the engine idling, depress the
clutch pedal and move the range lever (1), forward
to the High range or rearward to the Low range, as
required.
134
When the tractor is initially started and the main shift
lever placed in gear, the electronic control will
automatically select the appropriate powershift ratio
for a smooth pull away, as follows:
Gear Lever Positions
Ratio Selected
Field range (Low), 1 to 8
5th. gear
Road range (High), 9 to 16
9th. gear
For forward travel, with the engine idling, pull the
shuttle lever, toward the steering wheel, against light
spring-pressure, and move it up. It is not necessary
to depress the clutch pedal.
IMPORTANT: To select 14th gear or above, the
tractor must be travelling at a suitable speed before
the higher gears will engage. 14th gear or above
cannot be engaged when the tractor is stationery.
135
Once moving, press the upshift button (1), three
times and gears 6,
7 and 8 will be selected in
sequence. Alternatively, hold the button in and the
transmission will make sequential gear changes at
1.75 second intervals until the button is released or
8th. gear is reached. Use the downshift button (2) in
the same manner to make down shifts.
IMPORTANT: Downshifts of either one or more
gears, cannot be made if the tractor engine speed is
too high. To downshift, reduce tractor speed
(and
therefore engine speed) before attempting to
downshift.
136
IMPORTANT: Always use the clutch pedal when
changing between ranges 8th and 9th gears.
NOTE: When operating in temperatures below --18°
C (0° F) with cold transmission oil, avoid excessive
shuttle operations until the oil has warmed up.
2--89
SECTION 2 -- CONTROLS, INSTRUMENTS AND OPERATION
To reverse the direction of travel pull the shuttle lever
toward the steering wheel, then move it down.
Transmission output speed and clutch pack
engagement are automatically monitored to take up
the drive smoothly in the opposite direction. Control
tractor speed by means of the throttle.
NOTE: If, for example, 3rd. gear is selected in
forward travel, then the same ratio will be selected
when the shuttle lever is moved to the reverse travel
position.
If it is necessary to hillstart with a heavy trailer in low
range then, when 8th. speed is reached, change to
137
the high range, the transmission will automatically
select the lowest ratio (9th.) in the high range.
When starting off in the highest range, the
transmission will always try to set off in 9th. gear. If
required, this feature may be overridden and a higher
gear selected by partially releasing the clutch then
powershifting up to the required gear before the
clutch ‘bite’ point is reached.
IMPORTANT: A tractor with electronic transmission
cannot be tow-started and must not be towed other
than to remove it from a field or onto a trailer or truck.
Changing the Shuttle (reverse) Gear
(Digital Gear Display Only)
For certain applications it may be beneficial to
change the reverse gear ratio from the one normally
selected when shuttling i.e. 4th forward gear will be
matched by 4th reverse gear. If required, a reverse
ratio up to three gears higher, or lower, may be set
providing they are within the same range.
To select an alternative reverse ratio to the default
gear i.e. 4th, move the shuttle lever into reverse and,
with the tractor moving select 2nd gear using the
downshift button. The transmission will now
automatically select
2nd gear when moving the
138
shuttle lever into reverse.
This procedure may be applied in gear ranges 1--4
and 5--8. When moving from one range to another,
either upwards or downwards, the default reverse
gear will always be selected until the operator
chooses an alternative ratio.
When operating in the higher ratios 13--16, the
default reverse gear will always be 9th unless a lower
ratio is selected by the operator.
2--90
SECTION 2 -- CONTROLS, INSTRUMENTS AND OPERATION
Speed Matching
Speed matching will normally only permit a downshift
to a lower gear. It will however, select a higher gear
if the the engine attempts to overspeed.
When travelling on the road in High range, gears 13
to 16, the transmission will automatically select a
gear to match engine speed to road speed if the
following method is adopted:
To downshift: Decrease engine speed, depress the
clutch pedal while simultaneously increasing engine
speed by pressing the foot throttle further down.
When the clutch pedal is released, the transmission
will automatically select a lower gear (provided 13th.
speed is not already selected) matching engine
speed to road speed.
NOTE: When operating in Auto Shift high range, the
lowest downshift gear will become 9th, see text on
Auto Shift.
In high range, the operator can manually select
another gear without affecting the speed matching
function.
With the range lever placed in low, speed matching
will operate down to 5th gear.
NOTE: The speed matching function will be disabled
if the operator manually selects a gear when in the
low range.
2--91
SECTION 2 -- CONTROLS, INSTRUMENTS AND OPERATION
Auto Shift Function
(Active Electro Command Only)
With Auto Shift engaged, the transmission on your
tractor is able to make automatic gearshifts, both up
and down, within a 4 gear span based on speed and
load. This can be extended to an 8 gear auto shift in
the high range for road use.
Auto Shifting in Active Field Gears
In Active Field, auto shifts can be made within gear
spans 1--4 or 5--8. With the main shift lever in the low
range (lever fully rearward), momentarily depress
the Auto Shift button (1). The Active Field symbol
(plough) will appear in the gear display and the Auto
switch will illuminate to confirm engagement.
Moving off in
1st gear, the transmission will
automatically upshift through gears 2 and 3 until 4th
gear is engaged. To Auto Shift through gears 5 to 8,
select 5th gear using the range change button and
depress the Auto Shift button again, the transmission
139
will now automatically upshift through gears 5 to 8.
As the tractor speed reduces, or the load on the
engine increases, the transmission will automatically
downshift to a lower gear.
If necessary, Active Field can be extended to include
gears 9 to 12. To engage, move the main shift lever
fully forward to select any gear in the 9 to 12 range,
then depress the Auto Shift button again. To confirm
engagement, both Active Field and Active Road
symbols will illuminate.
In ranges 1--4, 5--8 and 9--12, Auto Shift may be
linked to 3--point hitch operation. Raising the 3--point
hitch with the fast raise switch will put Auto Shift into
140
standby mode, lowering the hitch will re--activate the
Auto Shift function.
NOTE: If the 3--point hitch was in the raised position
when the Auto Shift function was activated and has
not been moved, then Auto Shift will operate without
lowering the hitch.
Auto Shift will also enter standby mode if the clutch
pedal is depressed or the shuttle lever is moved from
the forward drive position.
To cancel Auto Shift press and release the switch or
operate the upshift or downshift button.
NOTE: When using engine braking to slow the
tractor, operating the upshift or downshift buttons will
not disable Auto Shift unless the selected gear is
outside the Auto Shift range.
2--92
SECTION 2 -- CONTROLS, INSTRUMENTS AND OPERATION
Changing the Active Field Auto Shift Gear
Span
In some field operations it may be beneficial to
reduce the number of Auto Shift gears in the span to
provide a more consistent tractor speed or engine
speed.
The Active Field Auto Shift function normally
operates within a four gear span, such as 1--4, 5--8
or 9--12. However, the number of auto shifts within a
selected range may be reduced from a 4 gear span
to a 3, or a 2 gear span as required.
NOTE: All adjustments to the Auto Shift span must
be made with the tractor moving and the relative Auto
Shift range selected.
NOTE: Changes made to the Auto Shift gear span
will not be retained at key--off.
Reducing the gear span upper limit: Increase
tractor speed until the current Auto Shift upper gear
is engaged then momentarily depress the downshift
button (2). The transmission will downshift one gear
which becomes the new upper limit Auto Shift gear.
To reduce the span further, depress the downshift
button again.
Raising the gear span upper limit: Increase
tractor speed until the upper gear is engaged then
momentarily depress the upshift button
(1).
141
Providing the currently engaged gear is not the
highest in the range, the transmission will upshift to
the next gear. This becomes the new Auto Shift
upper limit gear.
Reducing the gear span lower limit: Slow the
tractor until the lowest Auto Shift gear is engaged and
depress the downshift button (2) once. Providing the
currently engaged gear is not the lowest in the range,
the transmission will downshift one gear. This
becomes the new lower limit Auto Shift gear.
Raising the gear span lower limit: Reduce tractor
speed until the lowest Auto Shift gear is engaged and
momentarily depress the upshift button (2). The
transmission will upshift one gear, this becomes the
new lower limit Auto Shift gear.
