The patented levelling control system uses sensor technology
stability and tractive effort needed
for steep terrain. Additionally, a
variety of boom sets featuring thick
plates and large pins and bushings
offer a sturdy solution with the
reach and durability required for
steep slope logging.
The John Deere tracked carriers
can also be used with third-
party winch-controlled traction-
assist systems. These systems
allow tracked feller bunchers or
harvesters to be tethered together
using a winch or cable system,
helping with traction while also
increasing machine stability.
Wheeled solutions
A leader in wheeled solutions,
John Deere G-Series Harvesters
and Forwarders offer loggers the
stability and power needed for
working on steep and uneven
terrain. Each machine is equipped
with a patented balanced bogie
system designed to deliver
industry-leading tractive effort.
Additionally, the eight-wheeled
harvester and forwarders, including
the 1270G Eight-Wheel Harvesters,
offer operators even more traction
and stability, and can be fitted with
tracks if desired, helping to provide
better flotation with less ground
disruption compared to chains.
All John Deere G-Series
Wheeled Harvesters are equipped
with standard Processing Power
Control (PPC). PPC optimizes
fuel efficiency by anticipating
the engine load and responding
with the right power increase. An
advanced twin-pump hydraulic
system ensures ample power for
smooth, simultaneous operation
and maximum control of the boom
and harvester heads.
“The G-Series Harvesters were
designed to provide the power
and precision needed to tackle
steep slope terrain,” said Sakari
Suuriniemi, Product Marketing
Manager for John Deere. “The
incorporation of PPC ensures that
the operator can maintain precise
control of the boom and head, and
provides ample power to climb
steep slopes.”

Harvesters increases processing
capacity, enhances machine
performance and precision, and
improves operator productivity.
The rotating and levelling cab on
the G-Series Harvesters features
ergonomically designed seats
and air conditioning and heating,
reducing operator fatigue and
boosting productivity.
Designed to provide the power
needed for steep slope operations,
the G-Series forwarders feature
a larger hydrostatic-mechanical,
2-spread gearbox transmission,
providing more tractive effort than
previous models.
For a traction-assist solution,
German-based HAAS Maschinebau
has developed a solution
exclusively for John Deere wheeled
harvesters and forwarders. Being
used in a variety of markets
including Europe, South America
and North America, this proven
winch solution is installed on the
front or rear of the machine. This
allows the operator to work above
or below the extraction road.
Additionally, it can be fitted with
an optional straw-line winch to
simplify the jobsite set-up.
