They deliver high power and torque
and work in perfect harmony with
the highly efcient Dyna-6 and
Dyna-VT transmissions to give
outstanding performance in a
wide range of applications, with
excellent fuel economy.
More usable power
All of the engines have high torque
right down to 1,000 rpm, giving
incredible lugging ability to pull
through difcult conditions or to
help haul fully laden trailers on
long, steep gradients. There is
also signicantly more power at
2,000 rpm than at 2,200 rpm (rated
engine speed), to maximise PTO
performance.
An increased constant power
range of around 500 rpm, also
helps maintain work rate at lower
engine speed, giving reduced
noise and fuel consumption.
Advanced Electronic Engine
Management
The Electronic Engine Management
system 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 range is selected
or when the PTO is engaged, EEM
automatically gives a signicant
power and torque ‘boost’ (see
specications for details).
Any PTO application and any draft
application requiring a speed of at
least 8 Kph can therefore benet
from a signicant power increase.
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 ne adjustments to
fuel injection. Combined with four-
valve cylinder head design and
common rail fuel injection, this has
given signicant improvements in
both emissions and fuel economy.
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 the high-
pressure fuel injection.
The result is faster response to
changes in eld conditions and
engine load, more power and
torque over a wider engine speed
range, excellent fuel economy and
lower noise and emissions.
All models featured in this brochure are powered by either Perkins or
AGCO SISU POWER, Tier lll emissions-compliant engines, featuring
common rail fuel injection and 4-valve cylinder head design.
Plenty of power ...
and more in reserve
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 ow, giving
optimum fuel combustion and
reducing emissions and fuel
consumption, whilst also improving
engine reliability by reducing upper
cylinder temperature. The more
efcient combustion also improves
torque characteristics throughout
the whole working range.
The overall result of all of the new
engine features is that, model for
model, there is much more power
and torque.
01 Common rail fuel injection.
02 MF’s electronic engine
management system broadens the
operating range within which the
tractor is operating at optimum
fuel efciency.
03 Use ‘+/-‘ to pre-set engine
speed and ‘A/B’ to memorise and
select the required setting.
