HARVESTERS
903KH/909KH TRACKED

Tough equipment for a tough job.
Logging isn’t easy. Of course, nobody ever said it would be. And when it comes down to it, you’re
okay with that. But when you’ve got a tough job to do, you need equipment. We’re proud to say our
KH-Series Tracked Harvesters fit the bill.
The KH-Series is more powerful than ever. So you can get more done. Take on more of the forest. With
a larger displacement 9.0L engine, these machines deliver the power you need to move, swing, and
harvest faster than ever. Thanks to the lowest daily fuel cost in the industry, you’ll be more efficient
than ever, too. And with our redesigned cab, you’ll be more comfortable than ever.

Logging isn’t easy, but choosing — and using — your equipment should be. Which is why we’ve created
the KH-Series Tracked Harvesters. They’re tough machines that make your job, well, a little less tough.

Looking for a harvester that can handle the worst of the woods? Meet the KH-Series.

Redesigned cab. In the KH-Series, you’ll enjoy a clearer
view, a powerful HVAC system, more storage, and an
optional deluxe seat. We’ve also improved the placement
of the key switch and six USB ports for easy access.
Waratah factory installation. The KH-Series’ electrical
and hydraulic components have been factory installed and
fully documented for optimized performance and quick,
consistent troubleshooting. And with structural and hose
routing improvements, top-of-the-line Waratah harvesting
heads will keep you running longer, better.
Power. The 9.0L engine, available in 300 or 330 maximum
horsepower, makes lifting, swinging, and tracking
easier. And the 295-gallon fuel tank lets you get more done
between fill-ups.
CommandCenter. The factory-standard Advanced
Display Unit gives the operator a clear view of critical
gauges and superior on-board diagnostics. And the Sealed
Switch Module lasts ten times longer than standard dash
switches.
Service access. For ease of maintenance, there are two
points of entry into the engine and pump enclosure that
can be reached via a walkway from the cab so you don’t
have to leave the machine.
Debris management. The reverse cooling fan keeps leaves
and pine straw off the grill for better airflow to the engine
while on-demand fan speed keeps noise levels down, for
you and bystanders.
Hydraulics. With dual-swing motors for high torque, the
KH-Series has all the brawn you need — and a power management
system that makes sure none of your horsepower
is wasted.
Protected undercarriage. With double flange rollers for
maximum durability, this harvester handily clears nearly
every obstacle.

It works harder,
so you harvest easier.
The KH-Series is built to perform, from its factory-installed Waratah harvesting head to its agile,
long-wearing tracks. So you can get more done in less time. The woods will never know what hit ‘em.
Sturdy, hard-working boom designed specifically
for harvesting operations.
Powerful, factory-installed Waratah heads are
easy to inspect and maintain.
See the terrain, the trees, and the machine from
every angle, thanks to a skylight, a bottom window,
and better all-around visibility.
The 9.0L engine is unmatched in performance.
Reliable leveling keeps you secure on steep
inclines and rough terrain.
A high tractive effort-to-weight ratio with low
ground pressure guarantees agility.

Get in the know
with JDLink.
JDLink, John Deere’s innovative machine-monitoring
system, takes the guesswork out of productivity.
Through a secure Web site and text messages,
you can track location, fuel consumption, efficiency,
engine load, and more. Use the data you receive to
adjust your usage and work habits to get the most
from your machine — and your time on the worksite.
With JDLink, everyone from the operator to the
comptroller is on the same page.
With JDLink, you can:
• Get the data you need to adjust usage and boost
productivity.
• Be alerted when your machine needs attention.
• Know whether a machine is harvesting, idle, or
turned off.
• Estimate future jobs more accurately.
• Monitor fuel consumption rates.

More rock. Less roll.
Steep, rocky worksites are no problem for the KH-Series. Its bestin-class
leveling system keeps you steady, centered, and parallel
to the ground — even when climbing or tilting. That means you
can work in a wider area and stay focused on harvesting, not on
fighting gravity.
The KH-Series offers all-around leveling: 26
degrees forward, seven degrees rearward, and
14 degrees on either side.

Get where you need to go — this harvester
can handle steep grades, stumps, and sloping
terrain.

Where logging and
luxury meet.
You’re no stranger to the 12-hour workday. So you need a cab that’s built for comfort. One like we’ve
put in the KH-Series. Redesigned with you in mind, it’s got a deluxe seat. A wide view. A powerful HVAC
system. Brighter lighting. More convenient storage. New power ports. We like to think of it as the
logger’s lap of luxury.

With the new factory-mounted keyboard and mouse,
and repositioned key switch and USB port, you’ll have
everything you need in front of you and within a
comfortable reach.
With a redesigned HVAC system, this machine heats,
cools, and defrosts quickly so you’re ready to go in any
weather.
1. The KH-Series features better all-around visibility.
2. The optional Air Ride Seat reduces operator fatigue.
3. Refined harvester integration including factorymounted
keyboard and mouse.

4. You’ll appreciate the AM/FM/CD/AUX radio, factorywired
two- and three-pin connections for additional
accessories, two 12-volt power ports, expanded storage
space, and brighter cab lighting.

Harvesters that put you
ahead of the game.
With John Deere, harvesting heads are never an afterthought. The KH-Series was designed
specifically for top-of-the-line Waratah equipment, from our integrated plug-and-play wiring
to our factory-installed hydraulic system.

With several top-of-the-line Waratah head options — all
with integrated plug-and-play wiring and plumbing — your
operational capabilities have never been broader.
The KH-Series has been designed specifically for Waratah
heads, from the cab to the tip of the stick.
The consistent TimberRite measuring system optimizes
performance so you can spit out more trees every hour.
Structural and hose routing improvements.

Maximum Cutting Diameter (top saw) 16 in. (40 cm) 18 in. (45 cm) 20 in. (50 cm)

Uptime that won’t let you down.
Dependability. It’s one of the things we like most about the KH-Series. These machines are made
for maximum uptime, starting with an intuitive, easy-to-read, full-color LCD monitor that provides
onboard diagnostics, gauges, and vital system status lights. Then there are the longer-lifespan
switches, the protective hood, and the dual-swing drives that cut down on wear. The harvester
doesn’t disappoint — and won’t keep you waiting.
Logging isn’t easy. Of course, nobody ever said it would be. And when it comes down to it, you’re
okay with that. But when you’ve got a tough job to do, you need equipment. We’re proud to say our
KH-Series Tracked Harvesters fit the bill.
Another downward trend, a positive one, is lower operating costs. The KH-Series provides easy access
to components ad compartments to minimize maintenance time. Its superior design keeps you
running longer. And its best-in-class fuel economy means fill-ups won’t drain your budget.
1
1. Our Sealed Switch Module (SSM) lasts ten times
longer than traditional dash switches — and it’s
easy to see and reach.

2. The intuitive ROPS post-mounted, full-color LCD is
easy to navigate, well lit for night use, and starts up
immediately. Even in cold weather.
3. KH-Series hoses are routed to maximize flow — and
minimize potentially harmful heat build up.

Stronger, reinforced steel hood keeps internal
components safe from falling objects.
Low-velocity cooling system, designed to
accommodate engine heat loads, minimizes
the draw of debris.
Two swing drives keep loads evenly distributed
to prevent damage.
Reduced fuel consumption. The auto-idle
feature conserves fuel during non-productive
times, and the hydraulic reversing fan
draws just enough power to meet cooling
requirements.
Easier maintenance. The KH-Series offers
easy access to the engine and pump
compartment and all major compartments,
including rollers. Maintenance work that
used to cost you a day takes just an hour.
Smart design. From adjustable thrust bearings
that keep the tilt mechanism tight to
an in-tank hydraulic filtration with spin-on
filters for fewer filter changes and superior
dirt capture, the KH-Series is as reliable as it
is rugged.
An unmatched dealer network. When you
have a Deere, you have the entire John Deere
network at your disposal.
