With the powerful G-Series forestry
swing machines, 750K and 850K
crawler dozers, and 620G and 622G
motor graders from John Deere,
accessing the timber stand has
never been so easy.
G-Series forestry swing
machines
The 2154G, 2654G, 3154G
and 3754G forestry excavator
models were designed to handle
unpredictable land and arm loggers
with productive, durable and
reliable machines. These machines
were designed based on over a
half-century of experience, offering
customers increased comfort,
uptime and performance.
A standout feature within
the G-Series swing machines is
the spacious cab design, which
was developed with operator
comfort at the forefront. The
climate-controlled, roomy cab is
quieter than its predecessors, and
equipped with ergonomic controls,
exceptional window clarity,
isolation mounting and optional
LED lighting. These features
provide operators with not only
maximum visibility, resulting in
improved jobsite safety, but superb
comfort during long workdays,
boosting productivity.
Electrical components on the
G-Series machines have been
reduced by 30%, increasing
machine uptime by reducing future
trouble-shooting for electrical
issues. Additionally, the G-Series
machines feature increased airflow
and lower operating temperatures
because of the efficient hydraulic
management systems, reversing
fans and stronger coolers.
Serviceability is also made simpler
with enhanced service bays
equipped with drop-down work
platforms and LED service lights,
leading to increased uptime and
long-term durability.
The 3154G and 3754G models
each boast a powerful 9 litre
engine, while the smaller 2154G
and 2654G models are equipped
with 6.8 litre engines. The 3154G
features the same hydraulic
pump as the 3754G – making
them both reliable and durable
multifunctioning machines.
The 3754G has larger lower
rollers and a longer track frame
option, while the 2154G and
3154G models have more durable
lower rollers. The entire line-up
is equipped with more robust
components for the arm, boom,
mainframe and undercarriage,
ultimately increasing machine life
and productivity.
Crawler Dozers
Boasting PowerTech 6.8 litre Final
Tier 4 (FT4) diesel engines with 165
The 2154G, 2654G, 3154G and 3754G forestry excavator models were
designed to handle unpredictable land and arm loggers with productive,
durable and reliable machines
feature excellent total fluid
economy (diesel fuel and DEF).
Additionally, the diesel particulate
filter (DPF) cleaning occurs
automatically, without disrupting
machine productivity. Extensive
engine testing resulted in the DPF
being able to reach up to 15,000
hours before requiring ash removal.
featured in the cab provides
operators with transparency. This
monitor shows real time values
for every pressure, temperature
and speed sensor on the machine.
Transmission temperatures are
constantly being monitored within
the crawler dozers to avoid damage
to the hydrostat system.
Motor Graders
John Deere motor graders keep the shoulder clear of any heavy debris
HP and 205 HP respectively, the
750K and 850K crawler dozers are
highly productive machines that
offer increased uptime and lower
daily operating costs.
The 750K and 850K models
The 750K and 850K models also excel in steep slope application by using
innovative winch systems that assist with traction and increase machine
stability

Crawler dozers can be
incredibly helpful when accessing
the timber stand. The combination
of the FT4 engines, robust HP and
optimal fluid economy ensure that
when they are clearing obstacles,
spreading ballast, and cutting
paths for roads, productivity is
top of mind. The 750K and 850K
models also excel in steep slope
application by using innovative
winch systems that assist with
traction and increase machine
stability.
These dozers use hydrostatic
transmissions, a feature John
Deere developed in crawler dozers
in North America in 1976. The
electronic control system provides
customers with improved response
and controllability, increasing
productivity and boosting the
operator experience.
The LCD colour display monitor
The John Deere 620G and 622G
motor grader models feature ample
torque and blade pull to excel in
even the toughest terrain. With
operating weights of up to 42,000
lbs and equipped with FT4 6.8
litre engines, the 620G and 622G
models at 215 HP and 225 HP
respectively, provide the powerful
performance that customers expect
from the G-Series line-up.
Because of their levelling ability
through the grading process, the
620G and 622G motor graders
assist with accessing the tree stand
by keeping the shoulder of the road
properly levelled. With the support
of their impressive horsepower,
they can also be used to keep the
shoulder clear of any heavy debris.
A popular feature on the
machines, the dual joystick
provides operators with an intuitive
control to the standard antler rack
and minimizes hand movement
during direction changes and
gear shifting. This advancement
improves control comfort by
eliminating the need to ‘twist’
for blade circle or articulation
movements.
All John Deere motor graders
come standard with Eco Mode,
optimizing fuel usage. Eco Mode
decreases operating costs by an
extra five to 10 percent compared
to the larger 670G and 672G motor
grader models.
