MF 6400 and MF 7400
The driver’s choice

Straightforward ergonomic design, plenty of space, excellent
visibility and exceptionally low noise levels are the hallmarks of
the MF 6400 and MF 7400 cab. Add to that, automotive industry
quality materials and instrumentation, plus solid build quality and
you have the ideal environment to spend a productive working day.

01 MF 6400 Cab interior shown with

Dyna-6 transmission. Options shown

include AutoDrive, SMS and Datatronic III.

02 MF 7400 cab interior (with optional

Datatronic III and fi ngertip spool valves).

Thoughtful design

The layout of the cab is spacious
and well planned, with conveniently
placed switches, superb
instrumentation and controls
logically grouped by function.
All of the most frequently used
controls are mounted in the
right-hand armrest, which
moves with the seat so everything
always falls readily to hand.

Clarity at a glance

The instruments display information
either in digital, analogue or graphic
form to present data in the most
appropriate way for optimum clarity.

Quiet power

MF 6400 and MF 7400 tractors
are also exceptionally quiet, with
sound levels inside the cab of
70 dB(A) under load.

The tone of the sound has also
been ‘tuned’ to further reduce
any irritating noise, and levels of
vibration are minimised.

The result is that working long,
hard hours becomes far less
stressful and more productive. It’s
a driving experience that really has
to be tried to be fully appreciated.

A breath of fresh air

The heating and ventilation
system has a large number of
adjustable outlets, providing
excellent air distribution and
accurate temperature control.
There is also a choice of either
manually adjusted air conditioning
or full climate control*, which
will memorise your chosen
temperature setting and return to
it at start-up… automatically.

01

Excellent visibility

A large area of tinted, heat­refl ective glass, narrow pillars
and side-mounted exhaust all
help to ensure excellent all-round
visibility. Large telescopic rear view
mirrors - heated and electrically
adjustable on MF 7400 Series*,
and optional on MF 6400 Series,
are a further aid to safe
manoeuvring and transport.

The standard lighting gives
excellent night-time productivity,
with Xenon lights available as
an option for even higher
dusk and evening productivity.

Quiet, comfortable
and economical...
whatever the task

The standard seat provides exceptional comfort
but ride quality can be further enhanced...

01 The high specification swivelling seat,

featuring armrest-mounted controls and Dynamic

Damping System (DDS).

02 Lumber adjustment switch

on ‘super de-luxe’ seat.

03 QuadLink and cab

suspension switches,

giving full operator control.

High specification seats

The high specification, swivelling
seat is fully adjustable including
lumbar support, pneumatic height
adjustment, plus height and fore
and aft adjustment of the right
hand armrest so that the armrest­mounted controls can be perfectly
positioned. Options include a ‘low­frequency’, super de-luxe seat*
with double pneumatic lumbar
support, heating and ‘active
carbon’ seat covering for greater
comfort in really hot conditions.

QuadLink suspension

MF’s ‘QuadLink’ suspended front
axle* further enhances ride comfort
and control. It has a compact,
simple design that automatically
maintains a constant suspension
height, regardless of axle load.
The result is increased stability and
a significant improvement in driver
comfort, productivity and safety...
both on the road and in the field.

Operator-controlled

Unlike many other systems,
QuadLink is operator-controlled so
you can choose whether to have
the system on or off.

For example, when working in the
field with front linkage, where a
uniform depth of cultivation must
be maintained, it is beneficial to
be able to deactivate the system.
But when switched on, QuadLink
improves comfort, safety and
speed, especially in during loader
work.

Dual Stage suspended cab

To provide the ultimate in ride
comfort, MF’s cab suspension
system is available on all
MF 6400 and MF 7400 Series
tractors. The design features ‘dual
stage’ air suspension that can be
adjusted at the flick of a switch,
between two ride firmness settings

to suit field or road transport
conditions. This unique operator­controlled system stabilises cab
movement more effectively and
ensures a safer, more comfortable
ride in all conditions.

Ride comfort improvement

Compared to a ‘standard’ tractor,
the overall effect of having a high
specification seat, QuadLink
front axle suspension and cab
suspension can be a reduction in
vibration by up to 50%†.
The result is greater comfort when
operating for long periods, leading
to increased productivity, improved
work quality and a more relaxing
working day.

and more in reserve

All models featured in this brochure are powered by AGCO SISU
POWER, Tier lll emissions compliant engines, featuring common
rail fuel injection and 4-valve cylinder head design. They deliver
high power and torque and work in perfect harmony with the highly
efficient Dyna-6 and Dyna-VT transmissions to give superb field
and transport capabilities, with excellent fuel economy.

More usable power

All of the engines have significantly
more power at 2,000 rpm than at
2,200 rpm (rated engine speed).
This ‘power bulge’ gives incredible
lugging ability to pull through
difficult conditions or to help
haul fully laden trailers on long,
steep gradients.

Also, with an increased
constant power range of at
least 500 rpm, you can maintain
work rate at lower engine
speed, giving reduced noise
and fuel consumption.

Advanced Electronic
Engine Management

The Electronic Engine Management
system (EEM) controls not only
the very precise common rail
fuel injection, but also enables a
range of advanced engine control
functions, including Power Boost
and Engine Speed Control*.

Power boost

Due to sophisticated interaction
between the engine and
transmission management
systems, on MF 6400 models
when 3rd or 4th gear is selected
or when the PTO is engaged, EEM
automatically gives a significant
power and torque ‘boost’.

Engine speed control

Switches mounted conveniently
on the right-hand console enable
two engine speeds to be pre-set
and memorised.

This enables one engine speed to
be set for work and the other for
use when turning at the headland.

The ability to return quickly and
easily to precise engine speeds will
boost productivity, improve work
quality and simplify operation in
almost all of your daily tasks.

Improved fuel economy

Electronic engine management
constantly monitors a wide range
of parameters and makes continual
and incredibly fine adjustments to
fuel injection. Combined with four­valve cylinder head design and
Common Rail fuel injection, this has
given significant improvements in
both emissions and fuel economy.

Whilst lowering the absolute
Specific Fuel Consumption (SFC)
figure is important, the graph (right)
shows how the latest engines
achieve lower fuel consumption
over a much wider range of
operating conditions.

Common rail fuel injection

The common rail fuel injection
system uses precise electronic
control to continuously monitor
operating conditions and engine
load, and to regulate accordingly
the high-pressure fuel injection.

The result is faster response to
changes in field conditions and
engine load, more power and
torque over a wider engine speed
range, excellent fuel economy and
lower noise and emissions.

Four valves per cylinder

The cylinder head design features
two inlet valves and two exhaust
valves per cylinder enabling
the fuel injectors to be centrally
positioned in the cylinder head.

This design improves fuel/air
mixture and gas flow, giving
optimum fuel combustion and
reducing emissions and fuel
consumption, whilst also improving
engine reliability by reducing upper
cylinder temperature. The more
efficient combustion also improves
torque characteristics throughout
the whole working range.

transmission

With left-hand Power Control and smooth on-the-move clutchless
powershift changes, it’s simply the best ‘semi-powershift’
transmission in the fi eld today.

Simplicity and effi ciency

Dyna-6 uses four simple
synchromesh gears, each with
six Dynashift speeds. This wide
spread of speeds within each
range means you can change
up or down under full load as
conditions vary, to optimise output
and minimise fuel consumption.

Also, apart from starting the tractor
or hitching an implement, there is
never any need to use the clutch
pedal, so the seat can be swivelled
for fi eld work, eliminating the effort
of foot pedal operation. And with
a choice of either left- or right­hand control, there’s real operating
fl exibility to suit any application
or driver preference.

Left-hand Power Control

The left-hand Power Control lever
provides convenient forward/
reverse shuttle, powershift
changes, range changes* and
fi ngertip de-clutching, leaving the
right hand free to operate front
and rear mounted implements.

Shuttle operations are more effi cient
too, with programmable forward/
reverse speeds, to reduce repetitive
tasks and speed cycle times.

Right-hand control

The T-shaped gear lever is
mounted in the adjustable armrest,
so it’s always perfectly placed for
easy use. Simply ‘pulse’ the gear

lever forwards or backwards to
change up or down through
the six Dynashift ratios.

To change range, simply press
the range selection button as
you move the lever.

Dyna-6 AutoDrive (optional)
AutoDrive enables the operator to
select the engine speed at which
the transmission will automatically
upshift and will also downshift
automatically according to load.

The AutoDrive Controller has
three main settings:

• Manual, gives full manual
control with Speedmatching
switched off.

• Speedmatching, available within
both Transport and Field sectors,
provides automatic selection of
the most appropriate Dynashift
ratio after a range change has
been made.

Gear changes can then be made
either individually or rapidly, from
A to F range by holding the gear
lever (or Power Control lever)
forwards or backwards.

In Transport, sequential changes
also include range changes,
enabling 24 ratio changes, from
1A to 4F, all at the touch of either
the left-hand PowerControl lever
or the right-hand gear lever.

• AutoDrive (see diagrams on
right); in the Field sector, gives

fully automatic upshifting and

downshifting of Dynashift
changes, and in the Transport
sector, gives automated
Dynashift and range changes.

By adjusting the control, you
can pre-select the engine speed
at which upshifting takes place,
between 1600 and 2200 rpm.

Downshifting takes place when
engine speed falls under load
by around 20%, maintaining full
control and engine braking.

AutoDrive gives you total control
of the transmission, with the exact
level of automation you require for
any application, simply by turning
the AutoDrive Controller.

Creeper speeds

The (optional) creeper gearbox
provides a 4.0:1 speed reduction,
giving additional 12 forward
and 12 reverse creeper gears
with speeds down to around 400
metres per hour at rated engine
speed.
