Fuel effi ciency in the forest
In today’s economy, the amount of work you squeeze from a
gallon of diesel is paramount to survival. Yet, for a business
to thrive in this market, we know you need forestry machines
that burn the least amount of fuel per ton of wood moved.
We know it’s about optimum effi ciency.
That’s why at John Deere we look beyond the engine to the
entire drivetrain, including the transmission and hydraulics,
to ensure you are getting optimal equipment. We also compare
our machines head-to-head against competitive equipment to
ensure superior fuel effi ciency.
Recently we ran a controlled test that pitted our 748H
Skidder against a leading competitor. The Deere machine
moved 28-percent more material per hour than the competitor
on the same amount of fuel. Project this result across a
year, and the savings add up to about $9,000. Not too shabby!
You can run the numbers yourself by reading all about it at
I personally assure you that John Deere engineers are
working to deliver the best possible fuel effi ciency so you’ll
not only survive but will thrive in the current economic
climate. For more information on how we stack up in the
fuel-effi ciency arena, read the story that begins on page

You asked for it
And John Deere delivered. These new D-Series Swing Machines
are purpose built with loggers’ input front and center. Swing
torque, tractive effort, horsepower, hydraulic fl ow, and seamless
attachment integration all add up to more cycles per dollar for
your operation. The 2954D live heel boasts 12 more inches of
reach and a larger arm cylinder for additional lifting power, too.
There’s no mistake about it: These are some of the most
rough-and-tumble machines Deere has ever built. Their robust
upper frames include a strong boom tower, thick base plates,
substantial after-welding machining in critical areas, and largediameter
swing bearings. And the new heavier-duty booms and
arms are ready to take on all applications, from processing to
handling trees and any other jobs you throw their way.
Hail this cab
Depending on the machine’s application, the cab comes
mounted on either a 7- or 48-inch hydraulic tilting riser. And,
all models are available with rear-entry cabs with integrated
steps. These new D-Series machines provide the ultimate working
conditions while ensuring maximum productivity.
The D saves dollars
These new D-Series machines were bred for improved durability
so they stay in the forest and out of the maintenance or
repair bay. They are purpose built to stand up to harsh forest
environments, so each durable D model features a sturdy steel
frame, heavy-duty track chain, and a swing system with larger
bearings for extended wear life. The hydraulic cool-on-demand
fan allows the machine to continue producing, and the optional
reversing fan keeps the cooling system debris free.

Because anything less is really just prey.
Rising fuel costs cutting into your bottom line?
From the Southeast to the Northwest, loggers are feeling
the crunch of rising fuel costs, which have increased as
much as 60 percent in the last two years. With fuel prices
eating away at your profi t margins, it’s not enough to have
forestry equipment that is highly productive. To survive, you
need machines that are also extremely fuel effi cient.
Deere forest harvesting machines not only haul and
process more material, they are frugal, burning fewer gallons
per hour than leading competitors. Simply put, our highly
effi cient machines burn the least amount of fuel per ton of
harvested timber, which can save you thousands of dollars
every year and pad your bottom line with more profi t.
The Deere advantage
John Deere is passionate about designing and manufacturing
forestry machines that process more tons of timber per
gallon of diesel burned. Consider the miserly 748H Skidder,
for example. In a head-to-head comparison to one of the
industry’s leading competitors, the 748H moved
28-percent more tonnage per hour, while burning
14-percent less fuel. If diesel fuel costs $3
per gallon, that translates to savings of up
to $200 per week, or $9,000 per year,
and 13.5 more loads per week, or
607 more loads per year.
DARE TO COMPARE
Deere vs. the competition
In a series of side-by-side comparisons, Deere
forestry machines were tested against similarly
sized machines from other manufacturers. All
machines were confi gured as competitively
as possible to perform the same operation
on the same course. In demonstration after
demonstration, the Deere consistently proved
itself to be the more effi cient machine.
The Deere study matched the machines “apple for apple.”
The fuel savings fi gures assume 90-percent uptime at 10
hours per day, 5 days per week, 45 weeks per year, at $3
per gallon diesel cost. Actual conditions may vary. Check
www.JohnDeere.com/forestry for more details on the comparison
Deere knuckleboom delivers
The 437C Knuckleboom Log Loader also delivers impressive
fuel effi ciency and performance. In a side-by-side comparison
to a leading competitor, the 437C burned 34-percent
less fuel (2.5 gallons per hour), while processing 12-percent
more stems per hour and 11-percent more tons per hour.
Using a 437C, a logger could save $230 per week — or
$10,400 per year — while processing more tons than
the competitor. > > >
Factors impacting fuel economy
Fuel effi ciency is dependent on several factors, two of the most important being machine weight and type of transmission.
Here is what you need to consider when you are comparing fuel usage across brands and models:
Machine weight. Simply put, the lighter your machine,
the better your fuel economy. Weight is a particularly
important consideration for skidders. You want a machine
that pulls a lot of timber out of the woods, but doesn’t
drag a lot of heavy iron back into it. On average, Deere
skidders are 2,000 pounds lighter than comparably sized
machines from other manufacturers. Knuckleboom loaders
tend to stay put while they work, so weight is not a
signifi cant factor in fuel effi ciency.
Transmission. The type of transmission is another key
consideration. Direct-drive transmissions are the most
fuel effi cient, followed by the lockup torque converter.
Direct drive is available on the 648H and 748H Skidders,
while the lockup torque converter is available on the 648H
and the 848H.
The lockup torque converter stays engaged when
shifting gears and puts more power to the ground than
a regular torque converter. With advantages similar to
those of a direct-drive transmission, it is fuel effi cient.
Hydrostatic transmissions are the least fuel effi cient and
also generate a lot of heat.
Engines. If an engine is constantly cycling up and down
and hunting for the right rpm, then it’s probably burning
John Deere PowerTech Plus Tier 3 engines boast best-inclass
fuel economy, while delivering unprecedented power
and performance. To achieve improved fuel economy and
lower emissions, the engines employ three key technologies:
cooled exhaust gas recirculation, a variable-geometry
turbocharger, and a state-of-the-art engine-control unit.
Tires. Different tire widths can have a substantial impact
on fuel economy. Wider tires are heavier and create more
resistance, decreasing fuel effi ciency. If you decide to demo
several machines on your site to compare fuel effi ciency,
make sure all machines are confi gured exactly the same,
including being equipped with tires of the same widths.
Hydraulics. The 437C Knuckleboom Loader employs a
load-sensing hydraulic system that uses only as much
power as needed. Unlike other systems that share fl ow, the
Deere dedicated swing system features two-pump variable
displacement with a dedicated swing pump. The reduced
hydraulic load signifi cantly reduces fuel consumption.
Cooling. The hydraulically driven fan on John Deere skidders
runs only as needed, for more effi cient cooling and
reduced fuel consumption.

When you consider a typical Deere full-tree system, the
total annual savings are even more impressive. On average,
a logger in the South produces 450 tons per day (15 loads
times 30 tons per load). Assuming the logger burns 240
gallons in a 9-hour day with diesel at $3 a gallon, it will
cost him approximately $700 in fuel per day.
Here is where the miserly

system comprised of an 843J Feller
Buncher, two 648H Skidders, and a
437C Knuckleboom Loader decreases
fuel consumption 3.9 gallons per hour,
or 35 gallons per day, for a savings of
$105 per day.
If you cut 180,000 tons per
year, you’d save $0.23 per ton
on fuel, or over $25,000 per year.
That’s like receiving a fuel subsidy
of $0.23 per ton. ■
Selecting fuel-effi cient forestry equipment is an important fi rst step toward reducing fuel costs. But to haul the most timber
on the least amount of fuel, you need to abide by a few rules of the road. Here are a few suggestions:
Turn off the machine. If a machine is not in use, don’t let it
idle. It sounds like common sense, but a surprising number of
operators leave their machines running.
Don’t neglect maintenance. Well-maintained machines run
far more effi ciently. Again, this is common sense, but regular
maintenance doesn’t always get done.
Make sure operators are performing daily checks and
changing air and fuel fi lters regularly. Grease and service
your machines at prescribed intervals. Deere machines are
designed to ensure maintenance gets done quickly and easily.
Check tire pressure. Make sure tires are infl ated to the
correct pressure to match ground conditions.
Keep access roads in top shape. Keeping the roads you
use clean will help prevent trucks from getting stuck. This
eliminates the need to have skidders pull them out, saving
time and fuel.
Lay off the throttle. When you are trying to achieve maximum
productivity, you often run the machine as hard as you
can. But you may be able to achieve your quotas without
going full throttle.
Experiment with running at lower engine speeds and see
how it affects production. With knuckleboom loaders, for
example, you may fi nd you can run them 200-rpm slower
and still process wood effectively, depending on the jobsite
Think in terms of site effi ciency. It’s human nature for an
operator to work as fast as possible. But if your knuckleboom
loader has all it can handle, do your skidders really need to
The site foreman must consider the big picture and fi netune
the operation. Is there a machine that can’t keep up and
is causing a bottleneck? Can any of the other machines be
slowed down to burn fuel more effi ciently? The goal is to not
only maximize productivity, but to reduce fuel consumption
and daily operating costs as well, so you’re maximizing profi ts.
It starts stashing money away its fi rst day on the job.
Using up to 14% less fuel than a leading competitor, the industry’s best skidder is also its
most frugal. In a head-to-head study, the Deere 748H and a Tigercat 620C pulled an
18,540-lb. load on a ¾-mile course with measured fuel burns. The result? The 748H
moved 28% more tons per hour while using 14% less fuel. That translates to thousands
saved in fuel costs annually. So pad your bottom line. See your John Deere dealer today.
