IMPRESS THE GUYS BACK AT THE LANDING.
Standard decking blade has a
replaceable, weld-on cutting
edge of high-carbon material
for longer life.
A heavy-duty blade (optional on
the 648G-III, standard on the

You can count on John Deere Grapples to pick up a load the fi rst try.
The innovative G-III Series Grapples are designed with
two hydraulic cylinders, one for each tong, so they adjust
to each load with a secure grip. Closed-center, load-sensing
hydraulics maintain constant pressure on the tongs from
start to fi nish. Box construction with three internal ribs
on each tong makes them stronger without adding weight.
Choose from four single-function grapples
or three dual-function grapple versions.
A high torque motor drives the grapple
through 360-degree continuous rotation.
The single-function arch simply lowers and raises the
grapple head. It’s most productive working where it can pick up
tightly bunched piles in a single pass. Dual-arch geometry
uses four cylinders to reach out as well as lift. It pulls the load
over the rear for the best weight distribution and heavy load
control over longer hauls.

John Deere winches provide the power and
confi dence you need to skid big loads.
CABLE SKIDDERS
MAKE THE MOST OF EVERY LOAD.
G-III Series Cable Skidders have the power to skid big loads.
John Deere winches give you the power and reliability you need.
They are easy to operate with a single lever, and feature powerful
line pull, sealed wet-disc clutches, and spring-applied, hydraulically
activated brakes for extreme durability.
The rear assembly is built forest-tough to withstand the heavy
buffering they endure. The adjustable fairlead, heavy butt pan,
see-through ramguard screen, and strong fenders protect the tires,
rear frame, winch, and more importantly—the operator.
The fenders are shaped
to guide butts into the best
position for load control
during skidding.

THE 600 SERIES SKIDDERS
SKIDDERS
RUN CLEAN WITHOUT COMPROMISE.
The muscle behind the 600 Series Skidders is the powerful PowerTech Plus™
6.8 L engine that runs clean without sacrifi cing power.
All John Deere skidder engines meet EPA and CARB
emission non-road regulations, while maintaining the
legendary John Deere power.
Exhaust gas recirculation (EGR) cools and mixes measured
GRAPPLE 548G-III 648G-III 748G-III CABLE 540G-III 640G-III
amounts of exhaust gas with incoming fresh air to lower
peak combustion temperatures and reduce emissions.
And the engine’s four-valve design, with high-pressure
common rail fuel injection, provides greater low-speed
torque and better transient response.
The 600 Series Skidders feature an enhanced cooling system
with a new, more effi cient sucker fan design, which draws
air in the front, through the cooling package and out the
sides. The hydraulically driven cooling fan is temperature
controlled, so it runs only as needed, minimizing horsepower
use and drag. The fan is fully reversible to automatically
blow debris off the grill screen, optimizing air fl ow.

The hydraulic reversible fan maximizes
debris management, and productivity,
by automatically blowing off the screen.
The new sucker fan design on the cooling
package pulls air in through the front

Southern Thinning Special
Designed specifi cally to make fi rst thinnings more profi table, the optional 648G-III Single Arch Grapple Skidder can pull larger loads each turn
to increase the amount of wood to the landing every shift. It has a large 123-in (312 cm) grapple and an extended 145-in (368 cm) wheelbase
for better balance and stability to handle larger loads. The wider stance improves traction when reversing uphill or backing up to a gate delimber.
• New bulkhead fi ttings in the cab
improve the electrical system’s
reliability and simplifi es serviceability.
• The dual-arch 648G-III features a new
125-inch grapple, with 12.5 square
feet of carrying capacity, a 6.8%
increase over the previous model.
And added wear plating to the tongs
improves its durability.
• The fuel tank on the single- and
dual-arch 648G-III Skidders has
been increased by 10 gallons,
increasing the machine’s productivity
by minimizing fuel-ups.
• Torque converter transmission, with
six forward and three reverse gears,
available in the 648G-III Grapple
Skidder and 640G-III Cable Skidder.

All John Deere engines use an advanced, electronically controlled
fuel injection system that produces more torque for quick
turnaround and faster cycles. The common rail fuel injection system
controls the big power bulge programmed into the torque curve.
Power automatically adjusts as the load increases, optimizing
performance and productivity.
The quiet, isolation-mounted cabin on the G-III Series Skidders
will keep the operator working effortlessly without sacrifi cing
control or production effi ciency. The seat is fully adjustable
for individual height and weight, and it swivels so the operator
doesn’t have to. The steering wheel with spinner knob is adjustable
as well. And the soft-touch levers are positioned to give easy control
with the least amount of effort.
• The standard cab is isolation-mounted
for quiet operation, with tinted front
windshield, sun visor, and heavy screens
to secure the sides and back.
• The optional cab is fully enclosed with
polycarbonate windows on all openings
and screens on the door windows
only. This well-sealed cab keeps dust
out and helps the air conditioning,
venting, and heating systems operate
at peak effi ciency.
• Optional AM/FM stereo, located in
the contoured headliner with remote
speakers, has a CD or cassette option.
• An electronic hand throttle option with
three pre-set speeds lets the operator
free up his throttle pedal foot.
• The little things that mean a lot—
a dome light, storage under the armrest
with cell phone hookup, a beverage
holder, door bins, and easy-to-read
gauges, indicators and switches.
• Controls for heating, venting,
air conditioning, and windshield wipers
are handy without obstructing visibility.
• A quick glance tells you engine
temperature, transmission oil temperature,
and fuel level. The select button to the
left calls up digital readouts for hour
meter, gear selection, battery voltage,
engine rpm, and hydraulic oil temperature,
along with fault codes for the engine and
transmission. The warning indicators
across the bottom are accompanied by
audible alarm beeps, either critical for
immediate shut-down or cautionary to
warn of less critical malfunction.
• For really soft going, steep slopes
or severe ground, the smooth, steady
traction of the torque converter
powershift can make all the difference.
Some features differ from model to model.
Fast maneuvering with 90-degree stop-to-stop

AS RELIABLE AS THE WORKDAY IS LONG.
Building reliability into the transmissions and axles sets the G-III Series Skidders
apart from the competition load after load.
Not only are John Deere transmissions built to work effi ciently,
but the internal oil fl ow for the bearing to the front housing
gives a more consistent fl ow, eliminating external lines to
avoid damage and extending the transmission’s life cycle.
The engines have heavy-duty blocks, high-capacity oil and
water pumps, and hardened, replaceable wet cylinder liners
that make them as durable as they are productive.
With a choice of tires and axles, you can build a skidder
to your working conditions. The powerful, dependable
driveline gives you the rim pull to skid heavy loads shift
after shift. It all adds up to a skidder you can count on
no matter what the terrain.
Page 13
Direct drive or torque converter powershift—choose
the one that’s right for your job. The standard direct
drive powershift transmission puts the most power
to the axles on mostly fi rm ground and for short-tomedium skidding distances.
The 100-inch (254 cm) SWEDA axles, for fl otation
tires or duals, has a massive housing, large axle and
fl ange, plus its own dipstick for fast oil check.

and oil drain shut-off for spill-free oil changes make daily
maintenance a snap.
• The panel door behind the cab can be lowered for easy
access to HVAC’s fi lers, evaporators, blower motor, and
optional precleaner.
• Extended Coverage Warranty lets you custom fi t coverage
to your specifi c needs, giving you a fi xed cost for machine
repairs over a given period of time. Whether you work in a
severe-service operation or just want to spread the risk of
