New Holland T6010, T6020, T6030, T6050, T6070 Delta and Plus Tractors. Operator's Manual - page 4
SECTION 2 -- CONTROLS, INSTRUMENTS AND OPERATION
The Auto Shift gear span is shown in the
transmission display. Figures 142 and 143 show a 3
gear span of 6, 7 and 8. The currently selected gear
is 7th.
Digital Display: The span of gears will be
represented by flashing bars and the selected gear
by the solid block, see Figure 142.
LED Display: The span of gears will be identified by
flashing digits and the engaged gear by the
permanently lit digit, see Figure 143.
142
With Auto Shift in standby mode, the operator can
manually shift to any gear, even if it is outside the
current range of Auto Shift gears. Providing the
operator selects a gear within the current Auto Shift
range prior to exiting standby mode (i.e. lowering the
3--point hitch), then the Auto Shift function will be
resumed.
However, if the gear selected is outside the current
range when exiting standby, the Auto Shift function
will be cancelled.
If 8th gear is selected and the Auto Shift span is 5,
6 and 7, then the transmission will immediately
143
downshift to 7th gear on exiting standby mode.
If the Auto Shift span is 6, 7 and 8 and 5th gear is
selected on exiting the standby mode, then the
transmission will remain in 5th until conditions permit
a normal auto upshift to 6th gear. At this point the
original Auto Shift gear span of 6, 7, and 8 will be
re--instated.
2--94
SECTION 2 -- CONTROLS, INSTRUMENTS AND OPERATION
Auto Shifting in Road Gears
In Active Road, Auto Shift will make upshifts or
downshifts through gears 9--12 or 13--16. With the
main shift lever moved fully forward, momentarily
depress the Auto Shift button (1), the Active Road
symbol (trailer) will illuminate in the gear display to
confirm engagement.
The transmission will now make automatic shifts
through gears 9 to 12 or 13 to 16 dependant on the
range selected.
By depressing the Auto Shift button twice, Active
Road can be programmed to automatically upshift or
144
downshift through gears 9 to 16 including the range
change from 12th to 13th gear.
Changing the Shift Point
To suit different applications, the point at which the
transmission makes an automatic gear shift may be
adjusted from the default setting of 20%. Auto Shift
1
gear changes are related to an increase or decrease
in engine speed which can be set at 5, 10, 15, 20 or
25 percent.
NOTE: For transport operations the shift point will
automatically default to 20% if a lower figure has
been set. If the shift point is set at 25%, it will remain
at that setting.
With the shift point set at 10%, a transmission upshift
145
will occur every time the engine speed increases by
10%. Consequently, as the engine speed decreases
by the same amount, the transmission will make a
downshift.
It is recommended that during field operations the
shift point is set at a low percentage, and for road
transport applications, set at a higher figure.
To change the shift point, depress and hold the Auto
Shift button for at least one second. The current shift
point figure appears in the Display of Gears and the
’ramp’ symbol (1) begins to flash. Depress the Auto
Shift button repeatedly to scroll through the shift
points.
With the new shift point selected, release the Auto
Shift button and pause for five seconds. The new
setting will be memorised and the display will return
to normal.
IMPORTANT: At key--off (engine stop), electronic
programme settings made during tractor operation
are transferred from the operating memory to the
146
main memory. To provide sufficient time for the data
to transfer, allow a minimum of five seconds delay
before turning the key on again.
2--95
SECTION 2 -- CONTROLS, INSTRUMENTS AND OPERATION
Error Codes
In the unlikely event of a fault occurring in the
transmission controls or electronic circuitry, the
1
malfunction symbol (1) and a four-digit error code
(2), will appear in the Dot Matrix Display.
The code indicates the faulty circuit or sensor and the
type of fault, e.g., open circuit, short circuit, etc. In
2
this event, the tractor will require the attention of your
authorised dealer.
Should a fault occur causing the tractor to become
disabled, contact your authorised dealer and report
the error code displayed.
147
There are a number of ’action reqired’ error codes
which can also appear in the Dot Matrix Display,
these are listed below.
Error
Code Fault
P
Park brake on.
N
Place the shuttle lever in neutral.
CP
Depress clutch pedal to enable
transmission (restore drive).
Transmission Calibration
Should transmission shifts become slow or jerky, the
clutches in the transmission may require
re--calibrating. Consult your authorised dealer.
2--96
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 is installed within the rear axle
assembly.
As the name implies, the reduction gear set has the
effect of reducing all the ratios within the main
transmission to provide an additional sixteen gears
in forward and reverse.
The creeper gears are selected by means of a rocker
switch (1) located on the right-hand control console.
148
With the engine running, clutch depressed and the
shuttle lever in neutral, apply and hold down the
tractor footbrakes. Momentarily depress the upper
part of the selector switch (1), Figure 148, to engage
the creeper gears.
The creep speed symbol (1), will appear flashing in
the transmission display. When the creep gears are
fully engaged the symbol will cease to flash and
become steady.
To disengage creeper gears, repeat the above
procedure and depress the selector switch again.
The creep speed symbol will cease to illuminate.
149
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
DIFFERENTIAL LOCK
Four wheel drive tractors have a differential lock
installed in the front and rear axles to lock all four
wheels together in conditions where wheel slip may
occur. Two wheel drive tractors have a differential
lock in the rear axle only.
The differential locks are controlled by a spring
centered rocker switch on the console to the right of
the seat.
The differential lock(s) may be operated in manual
mode or automatic mode. To confirm mode selected,
150
the appropriate symbol on the switch will illuminate
when engaged.
WARNING
Avoid using the differential lock at speeds above
8km/h (5 MPH) and never at speeds above 15 km/h
(9 MPH) or at any time when turning the tractor.
When engaged, the differential lock will make
steering the tractor very difficult.
IMPORTANT: If wheel spin is encountered, reduce
engine speed before engaging the differential lock,
to avoid shock loads to the transmission.
Operating in Manual Mode
In slippery conditions, momentarily depress the
bottom of the switch (1) Figure 150 , to lock both
wheels together. The differential lock(s) will engage
and a warning light in the switch and on the
instrument panel (2) will light up.
When one or both brake pedals are applied or if the
switch is returned to the off
(central) position,
disengagement will occur and the warning lights in
the switch and instrument panel will go out.
Alternatively, depress the bottom of the switch again
to disengage the differential lock(s).
151
NOTE: The lock(s) will remain engaged until traction
at the wheels equalises.
2--102
SECTION 2 -- CONTROLS, INSTRUMENTS AND OPERATION
Operating in Automatic Mode (where fitted)
To engage both front and rear differential locks in
automatic mode, depress the top of the switch (1).
The warning light in the switch will illuminate. The
indicator light (1) Figure 153 on the instrument panel
will also illuminate but will only remain lit while the
differential locks are engaged.
In automatic mode, disengagement of the locks will
occur as follows:

SECTION 2 -- CONTROLS, INSTRUMENTS AND OPERATION
FOUR WHEEL DRIVE (where fitted)
Four wheel drive greatly improves traction in difficult
conditions. The drive to the front wheels is designed
to be engaged or disengaged with the tractor
stationary or moving.
NOTE: The drive to the front wheels is actuated by
a three position rocker switch on the right--hand
control console. To confirm mode selected, the
appropriate symbol on the switch will illuminate when
engaged.

SECTION 2 -- CONTROLS, INSTRUMENTS AND OPERATION
NOTE: The following applies only to tractors fitted
with a steering angle sensor.
• Wheel speed falls below 10 Km/h (6.2 MPH) and
steering angle exceeds
30°
(21° with
SuperSteer). Four wheel drive will re--engage
when the steering angle is reduced.
• Wheel speed is between 10 and 20 Km/h (6.2
and 12.4 MPH) and steering angle exceeds 25°
(17° with SuperSteeer). Four wheel drive will
re--engage when the steering angle is reduced.
NOTE: The above steering angles are set during
156
manufacture, if an alternative angle setting is
required, consult your authorised dealer.
The indicator light (1) Figure 156 on the instrument
panel will also illuminate but will only remain lit when
four wheel drive is engaged.
NOTE: To avoid excessive tyre wear when travelling
on the public highway or any hard surface, it is
recommended that four wheel drive be disengaged.
WARNING
Tractors with four wheel drive engaged or
disengaged should not be allowed to overspeed by
towing or coasting downhill with clutch depressed or
transmission in neutral. This may cause loss of
control, personal injury to the operator or bystanders
or failure of the drive shaft.
NOTE: Keep the tractor in the same gear going
downhill as would be used when going uphill.
WARNING
Your tractor is equipped with very efficient,
hydraulically actuated rear wheel brakes. On four
wheel drive tractors the drive to the front axle is
automatically engaged, at speeds above 8.5 km/h
(5.2 MPH), when the brakes are applied, to provide
four wheel braking. Owners should be aware of the
effectiveness of four wheel braking which greatly
enhances braking performance. Care should be
taken during heavy braking, particularly if the rear of
the tractor is unballasted.
2--105
SECTION 2 -- CONTROLS, INSTRUMENTS AND OPERATION
TERRAGLIDE™ FRONT AXLE
SUSPENSION (where fitted)
The optional, self-levelling, front axle suspension will
provide improved stability, control, comfort and
traction. Terraglide is automatically activated each
time the tractor is started but will not function at
speeds below 1.5 k/mh (0.9 MPH).
When operating at speeds up to 12 k/mh (7.4 MPH),
the front axle suspension may be locked out if not
required. A warning light in the switch will indicate
lock out is engaged.
157
To lock out the suspension, press the top of the
switch (1) on the right-hand control panel. Press the
top of the switch again to reactivate the suspension
facility.
At speeds above 12 k/mh (7.4 MPH), the suspension
will automatically re--engage, overriding axle lock
out. In this situation the warning light will remain on.
NOTE: Should the lock out switch warning light begin
to flash, this would indicate a malfunction of the
suspension system. Consult your authorised dealer.
IMPORTANT: See Ballasting and Tyres, page
3--136, regarding the use of front end weights with
front axle suspension.
WARNING
Hydraulic oil in the front axle suspension system
operates under very high pressure. Escaping
hydraulic oil under pressure can penetrate the skin
causing serious injury. Unqualified persons should
not attempt to disconnect any pipework in the front
axle hydraulic system. Failure to follow these
instructions can result in serious injury.
WARNING
If a transmission ratio is engaged, with the engine
running and the tractor supported on axle stands, the
self-levelling function of the suspension may cause
the axle to make corrections (move up and down).
The suspension should be locked out to maintain
stability.

SECTION 3 -- FIELD OPERATION
Turn off all electrical equipment not required and run
the tractor engine until the battery is fully charged.
IMPORTANT: When using an auxiliary battery to
start the engine, ensure that the polarity of the jump
leads is correct -- positive to positive, negative to
negative, otherwise the alternator may be damaged.
Only use an auxiliary battery if the tractor batteries
are discharged. Excessive amperage (above 1600
cca) may damage the starting motor. In the event of
the batteries being severely discharged, such that
terminal voltage is below 7 volts, recovery will require
a special charging procedure. See your authorised
dealer.
STARTING THE ENGINE
Before starting the engine, always carry out the
following procedure:
• Sit in the driver’s seat.
• Ensure that the parking brake is firmly applied.
• Ensure that all gearshift levers are in neutral.
• Ensure the shuttle lever is in neutral.
• Ensure that the P.T.O. knob is in the ‘off’ position.

An automatic ‘soft start’ facility is provided on all
models to permit easy start up of heavy, high inertia,
P.T.O.--driven equipment.
Soft start modulates P.T.O. clutch torque over the
first 5 seconds of engagement to provide a slower,
gradual take up of the drive.
NOTE: Soft start only operates at engine speeds of
1800 rev/min and below. Above this speed, normal
P.T.O. engagement will occur.
3--14
SECTION 3 -- FIELD OPERATION
With shiftable P.T.O., a range lever is provided. The
lever is used to select one of two or three P.T.O.
speed ranges to provide power or economy. The
range lever (1), is located at the rear of the right-hand
console.
Ground drive P.T.O. is available, in conjunction with
3--speed, shiftable P.T.O., on all models. As
suggested by the name, ground drive P.T.O. speed
is directly related to rotation of the rear wheels rather
than engine speed. When ground drive P.T.O. is
installed, a second lever (2) is provided.
Three ground speed ranges are provided, selected
15
by means of the P.T.O. range lever (1). The lever (2)
is used to select ground drive.
ATTACHING P.T.O. DRIVEN EQUIPMENT
CAUTION
Before attaching or detaching equipment or
changing the P.T.O. shaft:
• Firmly apply the parking brake.
• Ensure that all gearshift levers are in neutral.
• Disengage the P.T.O. (knob fully down) and wait
until the P.T.O. and equipment stops. Switch off
the engine before getting off the tractor.
With the engine stopped, the P.T.O. brake is released
and the shaft may be turned by hand to aid
implement shaft alignment.
Mount or hitch the equipment to the tractor as
outlined in THREE--POINT LINKAGE on page 3--83.
The P.T.O. guard serves as a support for drive-line
shields used with P.T.O.-driven equipment and
provides for your safety. Do not modify the guard. A
plastic P.T.O. cap (1) is also supplied and should
always be installed over the shaft when the P.T.O. is
not in use.

Check that you are using the correct P.T.O.
speed for the implement. Follow the instructions
in the equipment operator’s manual.
•
Ensure that the P.T.O. guard is installed when
using P.T.O. driven equipment.
•
Do not wear loose clothing when operating
P.T.O. driven equipment.
•
Firmly apply the parking brake, place all
gearshift levers in neutral and block all four
wheels before operating any stationary P.T.O.
equipment.
19
•
Do not approach, clean or adjust P.T.O. driven
equipment while the tractor engine is still
running. Disengage the P.T.O. (knob fully down)
and wait until the P.T.O. and equipment stops.
Switch off the engine before getting off the
tractor.
•
With the engine stopped, the P.T.O. brake is
released and the shaft may be turned by hand to
aid the installation or removal of the implement
P.T.O. shaft.

SECTION 3 -- FIELD OPERATION
TWO and THREE--SPEED P.T.O. SYSTEMS
General Information
Generally speaking, P.T.O. driven equipment not
having a high power requirement is designed to run
at 540 P.T.O. rev/min and will have a 6--spline female
coupling. A P.T.O. shaft speed of 540 rev/min is
obtained at an engine speed of 1970 rev/min.
Equipment having a high power requirement is
designed to operate at 1000 P.T.O. rev/min and will
be provided with a 21--spline female coupling. With
the 21--spline shaft installed, run the engine at 2120
rev/min to provide a P.T.O. speed of 1000 rev/min.
Equipment that requires very low power to operate
may be run in the alternative P.T.O. speed range at
a lower engine speed with a consequent reduction in
fuel consumption and engine wear.
Tractors with 3--speed P.T.O. have the advantage of
running low power 540 P.T.O. driven equipment at a
reduced engine speed by selecting 540E on the
lever. See page 3--24 for P.T.O. and engine speeds.
IMPORTANT: Implements with a high power
requirement should be operated with the
1000
rev/min. P.T.O. (21--spline shaft). If it is necessary to
use the 6--spline shaft (at 540 rev/min.) to operate
implements having a power requirement of more
than
75
horsepower, then it is strongly
recommended that the implement is fitted with a slip
clutch to avoid damage to the P.T.O. output shaft and
other tractor components.
NOTE: When required, change the P.T.O. shaft to
suit the operation and equipment in use, as
described under ‘Changing the P.T.O. Output Shaft’
on page 3--31 .
3--18
SECTION 3 -- FIELD OPERATION
TWO--SPEED P.T.O. WITH REVERSIBLE
OUTPUT SHAFT (where fitted)
Tractors with a reversible shaft P.T.O. system will be
supplied with a single output shaft having 6 and 21
splines.
Operating
With the engine running at 1000 rev/min., press the
knob (1) and lift the collar (3) and knob up to engage
the P.T.O. The knob will remain up while the P.T.O.
is engaged and the adjacent warning light (2) will be
illuminated.
IMPORTANT: To avoid shock loads to the P.T.O.,
reduce engine speed to approximately 1000 rev/min
when engaging the P.T.O.
21
Open the throttle to obtain the required engine/P.T.O.
speeds. The P.T.O. speed can be displayed in the
central LCD on the instrument panel (1).
NOTE: The light (2) Figure 21, will be illuminated
when the P.T.O. is engaged. If overspeeding of the
P.T.O. occurs (P.T.O. speed exceeds 630 rev/min)
the light will flash for 5 seconds, then remain steady.
When the 1000 rev/min/shaft is in use, the light may
also flash (but may be ignored) as P.T.O. shaft speed
passes through the 630 rev/min range. The light will
flash again at 1170 P.T.O. rev/min to indicate that
overspeeding has occurred in the 1000 rev/min
P.T.O. range.
22
Press the knob firmly down to disengage the P.T.O.
3--19
SECTION 3 -- FIELD OPERATION
NOTE: If the engine is stopped, the P.T.O. will not
operate when the engine is restarted until the P.T.O.
knob (1) is reset. Return the control knob manually
to the ‘off’ position (by pressing the knob down) then
re-engage the P.T.O., as previously described.
23
IMPORTANT: An automatic P.T.O. brake is installed
to stop shaft rotation quickly when the P.T.O. is
disengaged. To avoid overstressing the P.T.O.
brake, slow down the implement by reducing engine
speed before disengaging the P.T.O. This is
particularly important with implements having a high
inertia. Such implements should, ideally, be
equipped with an overrun clutch. To avoid damage to
the brake when operating high inertia implements,
hold down the switch (1), to disengage the brake and
allow the implement to come to rest naturally.
DANGER
To avoid inadvertent movement of the implement,
24
disengage the P.T.O. after each use.
CHANGING THE P.T.O. SHAFT SPEED
IMPORTANT: Before changing the speed of the
output shaft, switch off the P.T.O., stop the engine
and apply the handbrake.
Using a suitable tool, compress the lugs on the circlip
and remove it from the P.T.O. housing. Carefully
withdraw the output shaft.
NOTE: To aid removal, rotate the circlip until the lugs
(2), align with the flat on the P.T.O. shaft (1).
Thoroughly clean the P.T.O. shaft before re--inserting
25
it into the housing. Ensure the number of splines on
the shaft (3), correspond to those on the implement
drive shaft.
Replace the circlip ensuring it engages fully with the
groove in the P.T.O. housing.
IMPORTANT: After re--fitting, rotate the circlip 180°
in the housing so the lugs are opposite the flat on the
output shaft.

• WiththetractorstationaryandtheP.T.O.control
knob in the disengaged position, lift the
spring-loaded collar (2), beneath the knob, and
move the lever (1) fully to the right. This will
provide a P.T.O. speed of 1000 rev/min at 2120
engine rev/min.
NOTE: The P.T.O. range lever should always be in the
2120 position when the 21--spline shaft is installed. If
you only ever operate with a 21--spline shaft, leave the
range lever in this position.
27
With 6-- or 21--spline shaft installed
IMPORTANT: To avoid shock loads to the P.T.O.,
reduce engine speed to approximately 1000 rev/min
when engaging the P.T.O., then increase engine
speed by means of the throttle to obtain the required
P.T.O. speed.
With the engine running at 1000 rev/min. or less,
press the knob (1) and lift the collar (3) and knob up
to engage the P.T.O. The knob will remain up while
the P.T.O. is engaged and the adjacent warning light
(2) will be illuminated.
To disengage the P.T.O., press the P.T.O. control
knob (1), down.
NOTE: If the engine is stopped, the P.T.O. will not
operate when the engine is restarted until the P.T.O.

in the central LCD if required.
29
NOTE: If overspeeding of the P.T.O. occurs (i.e.
P.T.O. speed exceeds 630 rev/min) the light (2) will
flash for 5 seconds, then remain steady. When the
1000 rev/min shaft is in use, the light may also flash
(but may be ignored) as P.T.O. shaft speed passes
through the 630 rev/min range. The light will flash
again at
1170
P.T.O. rev/min to indicate that
overspeeding has occurred in the 1000 rev/min
P.T.O. range.
30
IMPORTANT: An automatic P.T.O. brake is installed
to stop shaft rotation quickly when the P.T.O. is
disengaged. To avoid overstressing the P.T.O.
brake, slow down the implement by reducing engine
speed before disengaging the P.T.O. This is
particularly important with implements having a high
inertia. Such implements should, ideally, be fitted
with an overrun clutch. To avoid damage to the brake
when operating high inertia implements, hold down
the switch (1), to disengage the brake and allow the
implement to come to rest naturally.

SECTION 3 -- FIELD OPERATION
AUTO P.T.O. FUNCTION (where fitted)
With Electronic Draft Control
The Auto P.T.O. function provides automatic
engagement or disengagement of the rear P.T.O.
drive when using the EDC raise/lower switch (1).
Operating the switch to raise the implement will
automatically disengage P.T.O. drive. Lowering the
implement with the switch will re--engage P.T.O.
drive.
The height at which the P.T.O. is engaged or
disengaged can be set using the following method.
39
IMPORTANT: The tractor must be stationary and the
P.T.O. switched off before attempting this procedure.
• With the engine running and the P.T.O. switched
off, operate the lift control to capture the hitch.
• Depress and hold the P.T.O. switch for
2
seconds. The central display will show
’u’
followed by two figures, for example, ’u38’. The
figure 38 representing the current height of the
hitch.
• Raise the hitch to point at which the P.T.O. is to
disengage. Depress the P.T.O. switch once, the
central display will show ’d xx’ (where ’xx’ is the
current height of the hitch).
• Lower the hitch to the point where the P.T.O. is
to re--engage and depress the P.T.O. switch
again. The central display will show ’End’ for two
seconds and then return to the option selected
prior to entering set--up mode.
Providing the tractor is stationary and the P.T.O. is
disengaged, this procedure can be carried out at any
time. The new settings will remain in the memory until
re--programmed.
