Tier 4 Interim
They are powered by the new Perkins 854E-E34TA 3.4L, four-
cylinder, turbo-aftercooled engines meeting the Tier 4 Interim
emission standards. Based on cutting-edge technology, these
engines feature a two-valve cylinder head and a common rail
injection system and deliver outstanding performance in terms
of power, torque and fuel economy.
The X50m tractors have a mechanical gearbox with synchro
shuttle lever under the steering wheel that provides four speeds
in three ranges, offering 12 forward and 12 reverse gears. The
basic transmission can be combined with an overdrive and a
creeper providing 24 forward and 12 reverse speeds.
Besides new more-efficient engines, the X50m range has also
received a brand new look. The hood has been fully redesigned
to reflect the new McCormick family styling and the cab interior
has been refreshed to offer the operator higher levels of
ergonomics and comfort.
The X50m tractors come in both two- and four-wheel drive
version with either a cab or an iso-mounted platform giving this
range all the versatility to tackle a wide variety of farming tasks.
The McCormick tractor line-up expands with the introduction of
the X50m Tier 4 Interim series. Developed as an evolution of the
C-Max, the X50m tractor range comprises three models with
power outputs from 85 to 102 hp: the 20, 30 and 40.

A
ENGINE
The X50m (Tier4i) tractors are powered by
the new Perkins 854E-E34TA four-cylinder
turbo-aftercooled engines with two-valve
cylinder head and electronic common rail
injection system that provide power outputs
from 85 to 102 hp.
These 3.4-liter engines utilize an innovative
exhaust gas recirculation system (EGR) in
conjunction with a diesel particulate filter
(DPF) to meet the Tier 4 Interim emission
regulations.
These units incorporate advanced
technologies that improve tractor
performance in terms of power, torque and
fuel economy.
Fully reshaped to reflect the new McCormick
family style, the tilt-up hood opens wide to
provide easy access to the engine
compartment for routine service and
maintenance.

FRONT AXLE
The 4WD front axle with electrohydraulic engagement offers a 55°
steering angle providing excellent ground clearance and optimum
manoeuvrability (fig. B).
The combined action of the front and rear wet disc brakes ensures
efficient braking on all four wheels. Featuring a full differential lock with
electrohydraulic engagement, the front axle provides maximum traction
even in the toughest ground conditions.
TRANSMISSION
The X50m tractors feature a modular
transmission (Speed Four) with four
speeds in three ranges (12FWD+12REV)
that provides a maximum speed of 30
km/h. This basic configuration is available
only for the 2WD version and can be
optionally equipped with a creep speed
unit. On the 4WD version, the “Speed
Four” transmission can be combined with
an overdrive unit to provide 24 forward
and 12 reverse gears and maximum speed
of 40 km/h. With the creeper option, this
configuration offers up to 36 forward and
12 reverse speeds (fig. C).
Conveniently located to the driver’s left
under the steering wheel, the synchro
shuttle lever allows for easy direction
changes. The same lever is also used to
engage the overdrive transmission (fig. D).
