with even more productivity- and uptime-boosting enhancements.
Eleven track frames, four
mainframes, and a variety
of blades let you choose the
right crawler configuration
for your kind of work.

Equipped with optional Integrated Grade Control (IGC), adding your preferred grade-control
system is “plug-and-play” easy.
Independent track control speeds up or slows
down each side – for smooth, full-power turns.
An automatic 10-percent power boost helps
carry more material in a turn.
No need to cross-steer or ride a brake. These
dozers steer the same and maintain their
preset speed whether working on level ground
or a 2-to-1 slope.

All dozers move the earth. But if you want one that does

Low-effort controls command
the blade and a full-featured
hydrostatic drivetrain, ensuring
predictable response at all
times in all conditions.
Simply set the maximum desired
ground speed and the powermanagement system automatically maintains peak engine rpm
and power efficiency without
stalling or shifting.
Infinitely variable range to 6.8
mph gives total flexibility to
match ground speed to the load.
Travel can also be varied to fit
specific applications, terrain, or
operating preferences — and
even limited to maximize undercarriage life.
Purpose-built mainframes for
power-angle-tilt and outsidemount blades allow optimized
component placement for
uncompromised grading ability.
Fully modulated drivetrain
ensures smooth starts and
direction changes, while
virtually eliminating jerky or
abrupt movements.
Counterrotation is a productivity-boosting feature
that enables an operator to overcome heavy
corner loads and quickly reposition the blade on
the go. Provides space-saving spot turns, too.

unsurpassed one-of-a-kind
control.
Want your operators to be more productive? Put them
in the seat of this spacious air-conditioned modular cab.
From their ergonomically designed fully customizable
controls to best-in-class visibility, J-Series Dozers
are loaded with everything you need to keep your
operators cool, calm, productive – and on your payroll.
Choose the decelerator
function that’s right for the
job. Slow both ground speed
and engine rpm, or ground
speed only to help maintain
traction without affecting
engine power and hydraulic
response. Fully depressing
the pedal applies the brakes.
Automotive-style
directional vents deliver
effective airflow to keep
the glass clear and the
cab comfortable. Air
conditioning is standard
on all cabs. For ROPS-only
crawlers, an optional underseat heater helps warm the
operator.
High-intensity halogen
driving lights are standard.
Or opt for the factoryinstalled 360-degree light
package and extend your
workday beyond normal
daylight hours.
Cab-forward design positions the operator for a more stable ride and a commanding
view behind, below, and beyond the blade. Side and rear visibility is equally unobstructed.
Monitor keeps a vigilant watch on vital machine functions with warnings you can see and hear.

No need for elevated
sprockets. Heavy-duty
double-reduction planetary
final drives are mounted
independent of the track
frames, where they’re
effectively protected from
shock loads.
One-piece rigid track frames

Bolt-on wear parts for the
chain guides and push-beam
mounts virtually eliminate
difficult and time-consuming

Perforations act as a “first filter,” preventing entry
of most debris. Anything that gets past the five-mm
holes also easily passes through the cooler cores.
Unitized mainframe with flush-fit bottom guards combines
with tight-fitting side shields to prevent debris from being
drawn into the engine compartment.
No stacked coolers in these crawlers. Side-by-side
cores with wide fin spacing reduce clogging and are
easy to clean.

Variable-speed fan automatically speeds up or slows down,
operating only as needed
to keep things cool. Helps
conserve power and fuel,
while reducing noise.
Air isn’t blown into the coolers,
so engine and transmission
reach operating temperatures
more quickly in cold weather.
Warm fluids flow easier, helping
extend component life, too.
Programmable fan automatically reverses to help eliminate
cooler-clogging buildup. Or
press a button on the dash
to actuate cleaning cycles as

With the fan positioned just
behind the grille, coolers are
less vulnerable to damage.
Hinged grille opens wide for
convenient clean-out.
Suction fan is more efficient
than blower designs, eliminating the need for oversize
coolers. There’s no need for
a radiator screen to decrease
tube erosion, either.

Control Owning and Operating Costs
Customer Personal Service (CPS) is part of John Deere’s proactive, fix-before-fail
strategy on machine maintenance that will help control costs, increase profits, and
reduce stress. Included in this comprehensive lineup of ongoing programs and services are:
Fluid analysis program – tells you what’s going on inside all of your machine’s
major components so you’ll know if there’s a problem before you see a decline in
performance. Fluid analysis is included in most extended coverage and preventivemaintenance agreements.
Component life-cycle data – gives you vital information on the projected life
span of components and lets you make informed decisions on machine maintenance
by telling you approximately how many hours of use you can expect from an
engine, transmission, or hydraulic pump. This information can be used to preempt
catastrophic downtime by servicing major components at about 80 percent of
their life cycle.
Preventive Maintenance (PM) agreements – give you a fixed cost for maintaining a machine for a given period of time. They also help you avoid downtime
Net engine power is with standard equipment including air cleaner, exhaust system, alternator, and
cooling fan at test conditions per ISO9249. No derating is required up to 10,000-ft. (3050 m) altitude.
Also available: winches, fair-leads, log arches, skidding grapples, trash packages, landfill protection
packages, cable plows, side booms, field-installed cab for canopy, canopy heater, and fire suppression systems.

by ensuring that critical maintenance work gets done right and on schedule. Onsite preventive maintenance service performed where and when you need it helps
protect you from the expense of catastrophic failures and lets you avoid wastedisposal hassles.
Extended coverage – gives you a fixed cost for machine repairs for a given
period of time so you can effectively manage costs. Whether you work in a severeservice setting or just want to spread the risk of doing business, this is a great
way to custom-fit coverage for your operation. And an extended coverage contract
also travels well because it’s backed by John Deere and is honored by all Deere
construction dealers.
Customer Support Advisors (CSAs) – Deere believes the CSA program lends
a personal quality to Customer Personal Service (CPS). Certified CSAs have the
knowledge and skills for helping make important decisions on machine maintenance and repair. Their mission is to help you implement a plan that’s right for
your business and take the burden of machine maintenance off your shoulders.
