Power at the speed you need

Tough transmissions

Challenger offers industry-leading
transmission options to tailor your
tractor to your unique applications.
MT400B Series tractors offer a
standard 16F/16R sychronised
manual shuttle transmission, with a
full power shuttle option available.
For even more refinement and
performance, the AutoPower IV
option can be specified. The
standard speed range is 2.7 to

40.2 kph. If slower speeds are
required, the tractor can be equipped
with either a creeper or a super­creeper option. The standard creeper
allows the tractor to operate at a
minimum 0.4 mph (0.6 kph) at rated
engine rpm. The super-creeper runs
as slow as 0.12 mph (0.19 kph).
The creeper and super-creeper

speeds are ideal for many specialised
planting and harvesting applications.

Speed selection and
shifting

Speed selection and shifting are
easy and comfortable with the
ergonomically designed right-hand
gear selector and a choice of either
a synchronised mechanical shuttle
or a single-function power shuttle.
The single “H” pattern of the shift
lever and push-button high/low
control allow for smooth gear
transitions when moving up or down
within the gear range.

flexibility over a wide speed range,
and delivering maximum field
performance. With the capability of
both powershift and range changes
being made under load, without the
need to use the clutch pedal,
AutoPower IV is exceptionally easy to
use. And with a choice of either left-

Caterpillar®engine - legendary strength and efficiency

Legendary Caterpillar 1104C diesel engines power each of the MT400B
Series tractors, providing outstanding power and reliability. In addition,
these engines include the latest Tier II technology for increased fuel
efficiency and decreased noise levels from their high-contact gear train.

or right-hand control, there’s real
operating flexibility to suit different
applications and driver preference.

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

With your right hand, simply move
the T-shaped gear lever forwards or
backwards to change up or down
through the four powershift ratios.
To change range, simply press the
range selection button as you move
the lever. When changing range,
speedmatching automatically selects
the correct AutoPower IV ratio to
match the tractor’s forward speed.

Your choice of axle

The MT400B Series offers you the
choice between a 2 or 4WD front
axle to give you the perfect machine
for your specific applications.

4WD front axle

The axle is designed as an integral
component of the tractor, not an
add-on, and is perfectly matched to
the tractor’s horsepower and chassis
size. The system features a centre­line drive and has no universal joints
in the driveline from the
transmission to the front axle. The
front axle drive operates electro­hydraulically with the push of a button
from a rocker switch in the cab.
Additionally, the 4WD front axle will
engage when the brake pedals are
pressed at the same time, delivering
4-wheel braking capability and
increasing control with heavy loads.

More power, more control, more productivity

MT400B

Challenger hydraulics

Open-centre hydraulics are standard
on the MT400B Series, offering
hydraulic flow and pressure for a
wide range of applications. Two
mechanical valves are standard with
the option to add valves up to a
maximum of four. If a joystick is
required, two mechanical valves can
be combined in a mechanical joystick
configuration. In addition, a dedicated
loader joystick can also be added to
allow the remotes to be used for
operating other implements.

As an option on these machines,
100 l/min oil flow can be achieved
by combining the flow from two
hydraulic pumps. The higher flow is
made available by the simple flick of
a switch that "locks out" the 3-point
linkage, providing extra speed and
power for loader work.

Electronically controlled
3-point rear linkage

Linkage-mounted implements can
be controlled with precision using
the MT400B Series’ Electronic
Linkage Control (ELC) 3-point hitch.
These category II hitches are ideal
for implements such as planters,
cultivators, rear blades and mowers.
Also available on the MT400B Series
is a factory-installed front linkage
package, including front hydraulics
and PTO, with the front PTO
electro-hydraulically engaged
through a console-mounted rocker
switch. The system is ideal for
cultivation equipment and other
implements, offering a better
operator view compared to more
traditional rear-mounted tools.

System control

The system's controls allow for quick
customisation for various tasks such as
mowing, cultivating and grading. The
integrated Active Transport Control on
the rear linkage works independently of
the transport lock to absorb shock and
minimise the pitching action,
automatically adjusting for different
implement weights. It can be controlled
manually or linked to the ELC's
lift/lower system to activate
automatically as required for smoother,
safer and faster transport with minimal
damage to the lift system.

PTO

The PTO on the MT400B Series has
been carefully designed. Each
features an independent
(540/540E/1000 rpm) PTO. Speeds
are easily read on the digital display
on the cab instrument panel, and the
PTO can be engaged and disengaged
independently of the main
transmission clutch, allowing for
starting and stopping at any time for
optimum productivity.

engine speed by 23 percent, from
2000 rpm to 1550 rpm, while still
maintaining full PTO shaft speed. The
slower engine speeds reduce fuel
usage, noise and vibration while
increasing overall tractor versatility
and engine life.

A live shaft drives the electronically
controlled system through a wet
multi-disc clutch. The PTO
automatically disengages when the
engine is turned off, while a
hydraulic brake prevents shaft
rotation when the PTO isn’t engaged.

The economy PTO is perfect for
equipment that does not require
maximum horsepower. It reduces

No longer a chore

Service and maintenance

Daily service points on the MT400B Series are at your fingertips.
Standard side panels are fully removable and give unobstructed
access to the engine, air filter, coolant level, belts, alternator, air
conditioning compressor and windscreen washer fluid. The radiator,
oil cooler and air conditioning condenser are also easy to reach for
cleaning and maintenance.

Daily service checks such as the engine oil level, engine oil fill and
fuel filter drain are accessed without removing the side panels.
Transmission and hydraulic oil checks are done from the rear of the
tractor. The MT400B Series tractors feature ground level fuelling with
a large opening to minimise backsplashes and spills.

Equipped for the job

MT400B Series models are equipped
to handle a wide variety of tasks,
whether the job is up front or behind
the tractor. The electronically
controlled 3-point hitch, for example,
features electronic draft sensing and a
standard lift capacity of 5000 kgs or
an optional 6000 kgs. With a total
hydraulic flow of 132 l/min, with
57 l/min available at the remotes,
MT400B Series tractors also offer a
combined flow option which gives you
100 l/min flow at the spool valves
which is very useful for loader work.

A 540/540E/1000 rpm PTO is also
standard on all models.

Best of all, these tractors are a
pleasure to drive and easy to
operate. Regardless of which
productivity features you use most
often, the controls are well organised
and within easy reach.
