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

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.


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 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

more fuel.

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

Deere forestry system helps you

keep more profi ts. A typical

How you can improve fuel effi ciency

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

and application.

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

go all-out?

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.
