From thinning through nal harvest applications, the
CSeries model line up is the most versatile in the industry.

563C
The heart of the CSeries wheel feller buncher is the 563C.

From thinning to nal harvest, the 563C is the best of both
worlds with more power and stability, as well as a shorter
wheelbase for improved agility.

573C
The 573C delivers unmatched performance in the most

severe applications and was developed to excel in
large timber, adverse terrain and ultra high production
applications. The 573C is larger than the 563C, making
itthe most powerful and stable machine in the market.

We Get It.

You asked, we answered.

The “Voice of the Customer” drove the design of the completely new Cat® CSeries wheel feller buncher. We heard your voice loud
andclear at every stage of the machine’s development.

You asked for a machine with…

Lower Owning and Operating Costs

Even with the more powerful Cat® C7.1 ACERT™ engine,
field data and customer input have shown an improvement
in fuel efficiency. You’ll burn less fuel and get more power
because of Caterpillar’s advances in engine technology and
machine design. This includes more power generated at lower
rpms and an on-demand cooling fan that only spins when
needed and, therefore, draws less engine power.

Ground Level Serviceability

Serviceability has been reinvented with the CSeries – the first
and only wheel feller buncher that can be serviced standing
on˛the ground. This includes fueling. Many other features
contribute to the ease and safety of servicing the CSeries
machines: hinged access panels, tilting cab, and three-sided
access to the engine and hydraulic pump, to name a few.

Powerful Performance

Power, stability, agility and superior multi-functioning
capability work together to give you the performance
youneed to maximize productivity.

The new Cat C7.1 ACERT engine delivers power where
andwhen it is needed as a result of PowerDirect Plus, a new
system that optimizes machine efficiency, performance and
productivity. You’ll see better performance in all applications
on both steep and flat ground. Simultaneous lift-tilt and lift­steer functions and saw recovery are significantly faster than
major competitive machines.

Unprecedented Stability and Agility

Place trees where you want with the unmatched cut and
carry capability of the CSeries. The engine was placed at
the back of the machine providing better weight distribution
and balance. The center hitch is positioned between the front
and rear axles to facilitate tire tracking. Combined with
the improved weight distribution and balance that results
from the rear engine position, the agility of the CSeries is
adistinct advantage.

Unmatched Reliability

Robust box section frames and a field-proven center hitch
design provide a solid foundation for a machine designed to
keep you in the woods. New components – like the control
valve, pumps and cylinder seals – were “torture” tested to
ensure reliability. Steering cylinder mounts and chrome
plated lift arm and tilt link pins are two more examples of
structural changes built into the CSeries to increase uptime
and machine life.

Comfortable and Adjustable Operator Station

The cab is centered between the axles for a smooth ride.
Thestandard air suspension seat with neck and back support
and new high capacity HVAC system adds to your comfort.
A clean three-piece front windshield, large rear windows
and skylight give you a 360º view, including the rear tires.
The CSeries features additional functions including Control
Adjustability, Terrain Selection Mode, Creep Mode, and
Road Steer Mode.

Engine

More horsepower, less fuel

The Cat C7.1 ACERT engine delivers more horsepower using less fuel than the previous series engine.
The C7.1 meets U.S. Tier 4 Interim and EU Stage IIIB emission standards. In designing the C7.1, new
technology was incorporated to ensure that changes to meet emissions requirements would not increase
operating costs,reduce uptime or shorten service life.

Emissions Solution

Driven by customer input, Caterpillar’s aftertreatment regeneration works with no operator
intervention needed. The machine comes with two modes of regeneration: automatic and manual.

In automatic mode, the machine starts the regeneration process once the filtering system reaches a
certain level and conditions are optimal. Productivity is not affected by the regeneration process. The
system will not interrupt work and can regenerate during machine operation with no impact on
machine performance.

With a touch of a button inside the cab, the operator can override the automatic mode and switch to
manual mode for initiating the regeneration process.

On average, regeneration is needed only every 10 hours and takes 20-25 minutes. The diesel particulate
filter only needs to be cleaned every 5,000 hours – approximately every two years.

Biodiesel-ready Fuel System

The C7.1 ACERT engine is equipped with an electronic-controlled high-pressure fuel system that includes
an electric priming pump and three-layer fuel hose to allow the use of biodiesel (meeting ASTM6751
orEN14214) up to B20 (biodiesel 20 percent mixture).

4

Cooling System

High capacity, easy servicing

The high capacity cooling system and on-demand reversing fan
keep the machine running at the proper operating temperature,
optimizing performance, durability and fuel efficiency.

Cooling System

The cooling system is arranged in two panel sections for easy
access to all components. The air conditioning condenser
and fuel cooler are in a hinged panel that tilts out for easy
cleaning and access to the other section with the side-by-side
mounted hydraulic oil cooler, engine radiator and air to air
after cooler (ATAAC).

On-demand Reversing Fan

The oversized, hydraulically driven fan spins at a slower
speed overall and only turns as fast as needed to maintain
proper hydraulic and engine temperatures. In colder weather
or when the machine is first started, for example, the fan
spins more slowly to conserve power and fuel and reduce
noise. Air is pulled in from the side – not from the engine
and not from under the hood – preventing debris build­up around the engine. It automatically reverses every five
minutes of run time to keep the cooling system free of debris.
A manual override allows the operator to activate reversal
between scheduled cycles. A heavy-duty fan shroud provides
protection when servicing.

5

Power Train

New pump layout adds to durability

The new Cat C7.1 engine, field-proven hydrostatic drive and
axles make a solid, responsive power train. A new design for
keeping the pump drive and gearbox well lubricated gives it
even more durability.

Dual Pad Pump Drive

Caterpillar’s CSeries design features a dual pad pump drive.
One drive runs the attachment and main pumps; the other
runs the hydrostat and fan pumps. The improved dual pad
pump drive is more durable because it is not dependent on
splash lubrication.

Two-speed Gearbox

Similar to the pump drive, the two-speed gearbox is now
mounted horizontally instead of vertically, eliminating the
need for splash lubrication and improving durability.

Axles

Axles feature a full-length oil sump for excellent heat rejection
and long component life when using single tires (upto 30.5 × 32
with chains), odd size dual tires (up to 30.5 × 32 with 24.5 × 32),
or wide flotation tires (up to 73 × 44). Anoscillating rear
axle absorbs shock loads caused by stumps and holes and
helps isolate the cab from axle movement for a smooth,
comfortable ride, while maximizing fore-aft stability.

Brakes

The inline parking brake is spring applied and hydraulically
released. Inboard service brakes provide excellent performance
and are protected from water, dust and oil.

Differential Locks

During normal operation all four wheels move independently
to maximize agility. In extreme conditions like slippery or
steep terrain, pressing and holding a trigger button on the
joystick will engage the front differential lock to make the
front tires turn in sync. The rear differential lock is easily
engaged and disengaged by an on/off button on the right
hand console.

6

Structures

Durability built into every part

Robust box section frames provide a solid foundation for a machine designed to keep you in the woods.
Every structure was engineered for durability and verified through lab and field tests.

Center Hitch

The field-proven center hitch design features large dual tapered roller bearings and 76.2 mm (3 in)
diameter pins providing maximum durability. With up to 90º articulation, maneuverability in tight
thinning stands is an advantage of the Cat wheel feller bunchers.

Lift Arms

The precision manufactured lift arms are rugged and designed to support severe loading from
theattachment.

Pins

Lift arm and tilt link pins are 63.5 mm (2.5 in) diameter and chrome-plated to prevent corrosion.
Micro-cracks in the chrome plating help retain grease on the pin surface to increase durability.

Steering Cylinder Mounts

The steering cylinders are mounted to large, thick plates that are integrated into the frame and extend
from the steering cylinders in the center hitch to the axle housings in the front and rear of the machine.
These plates carry the steering cylinder force straight to the axles, rather than sending the load through
the machine’s frame, increasing structural life.

Other Structural Features Include:

• Robust guarding on the tilt arm cylinders to prevent damage from limbs.

• New cylindrical steering stops designed to take abuse and protect the frame when the machine

makes a hard turn.

• Big, rigid steps with gripper surface.

7

Hydraulics

Fast and smooth with PowerDirect Plus

The heart of the CSeries hydraulic system is the new
PowerDirect Plus system, which goes beyond load sensing
toefficiently distribute power to increase the capability of
each system and maximize productivity.

Electrohydraulic Controls

The new CSeries features an electrohydraulic control
system.The pedals and joysticks communicate through the
machine controller to the pumps and motors using electrical
signals, rather than hydraulic, to produce more precise and
smoother control.

PowerDirect Plus

PowerDirect Plus is a new system that optimizes the machine’s
performance by monitoring operator and attachment demand
and delivering power where and when it is needed.

PowerDirect Plus does not require the operator to reduce
demand or do anything differently – just focus on the work
and push the machine. Critical machine systems in the
CSeries are oversized, which increases overall machine
capacity. This gives each machine system – hydrostat, main,
attachment and fan – more capability than ever before.

PowerDirect Plus provides better performance in all
applications on both steep and flat ground. If you’re carrying
a tree in the head and backing up a hill, the system will focus
full power to the drivetrain. On flat ground where drivetrain
demand is lower, more power is available to the attachment
and the oversized attachment pump pushes more flow to the
saw. Saw recovery time is significantly faster compared to
previous wheel feller bunchers.

Control Valve and Pumps

Multi-functioning, always an advantage for Cat wheel
feller bunchers, is the result of a high performance control
valve. In addition to field-testing, we put the control valve
and hydraulic pumps through extensive lab “torture”
tests that simulated the most brutal logging conditions
and environment. The tests verified a significant increase
intheservice life of the control valve and pumps.

Cylinder Seals

Rigorous testing similar to the control valve and pumpsand
side-by-side testing against competitive cylinders was conducted
on the new cylinder seal packages to ensure durability.

8

Filtration

Dual spin-on hydraulic oil filters keep hydraulic oil clean, which is critical for machine health.
Theelectric fill pump uses a quick coupler hose stored on the machine to pump oil through the
filtration system before it enters the tank, safeguarding the hydraulic system.

Cat Hoses

Cat ToughGuard™ hoses and O-ring face seals throughout the machine improve machine life and
reliability, particularly along the lift arms and through the center hitch due to the increased strength
and flexibility. The ToughGuard cover consists of a layer of UHMW polyethylene bonded to the
rubbercover, providing exceptional abrasion resistance. Extreme-duty rubber tube covers provide
additional protection to the lift arm hoses. The covers reduce downtime by deflecting impact to
thehoses from debris.

9

Operator Station

Superior comfort and visibility

Comfort and visibility, of course, but you’ll find cab features that go beyond the basics to give you control options that can be
customized and new operating functions, including special modes for thinning, road travel and terrain settings.

Ride

Sit on either end of a teeter-totter and feel every bump; sitinthe center and get a level, smoothride. This principle applies to
the new CSeries. The cab is centered between the axles for the most comfortable ride possible. No bucking. The standard air
suspension seat with neck and back support adds to a smooth ride, keeping the operator comfortable andfocused.

HVAC System

The durable, high capacity HVAC (heating, ventilation, andair conditioning) system provides dependable cooling or heating no
matter how hot or cold it gets. Vents in front and on both sides can be directed toward the operator or the windows. Thisalso
contributes to increased operator productivity and can help reduce mental and physical fatigue at the end of the day.

Visibility

A clean three-piece front windshield, large rear window andskylight give the operator a 360° view, including the rear tires.
Theoperator can see the work zone easily without having to strain or move the machine around all day. Witha clear view

tothetreetops, picking out the bad or stunted trees inthinning jobs is faster.

10

Monitor

The display allows the operator to continuously monitor the machine’s
systems. Early indications give the operator the opportunity to react
before potential problems become actual problems. A clean and clear
monitor provides detailed machine data to maximize machine uptime
and productivity. Finding information is intuitive:

• The home screen displays the condition of primary systems, such

• If an engine or hydraulic problem occurs, the monitor will display

• If a machine condition requires immediate action, a warning

• Everything the system does is recorded in the system log, a useful

as fuel level, engine and hydraulic temperatures, and engine and
saw rpms. Press the corresponding button along the bottom of
the screen to get more detail on any item. As an example, under
the hydraulic system selection, the two-speed gearbox oil level
indicator is displayed.

an easy-to-understand text explanation, along with any applicable
fault codes.

buzzer will sound to draw the operator’s attention to the monitor.
The operator must acknowledge the warning to turn off the
alarm. Depending on how serious the warning, the alarm will
continue to sound until the condition is remedied.

feature for monitoring machine health andoperator activity.

Control Adjustability

All key operator functions – steering, lift and tilt – are fully adjustable
through the machine monitor. Overall speed and response to operator
input can be adjusted, maximizing operator comfort and performance.
The gathering arm and bunching finger controls also are easily
reversed, iftheoperator is used to that configuration.

Joysticks

New electrohydraulic joysticks mold to the operator’s hands for all day
comfort and increased functionality. Converting to electrohydraulic
control also means the hydraulic pilot lines running to the joysticks
could be removed, eliminating apotential source of heat in the cab.

Button Pad

The button pad on the right hand console features on/off buttons
clearly labeled with large icons for many features, including the
parking brake, hydraulic arming and reversingfan.

Other Cab Features Include:

• Two cup holders

• Two 12-volt power points for cell phone chargers etc.

• Coat hook

• Optional AM/FM/CD/Sirius satellite radio package withUSB

andauxiliary inputs

• Multiple steering and gathering arm control configurations

11

Advanced Controls

Maximize machine and operator performance

Unique operating modes, combined with complete
electrohydraulic controls, provide the operator with a
smoother machine with increased productivity. These modes
include Terrain Selection Mode to optimize performance
on hills or flat ground, Creep Mode to improve machine
functionality, particularly in first thinnings, and Road Steer
Mode for high-speed transport of the machine.

• Terrain Selection Mode: Quickly and easily optimize

machine performance based on application requirements.
Select Hill Mode to boost drivetrain power for working
in rough conditions like hills, wet ground or bedded
plantations. Select Flat Mode to maximize speed
and optimize fuel efficiency when ground conditions
aregood.

• Creep Mode: A great feature for first thinning applications,

Creep Mode gives the operator the ability to dial down
the speed of the machine when a propel pedal is depressed
completely. This allows the operator to keep the pedal
depressed – rather than continually having to start and
stop – while working down a row of trees. Noneed for
feathering to find that sweet spot – just relax and push
the pedal completely down. The Creep Mode makes it
easy to get into a steady rhythm of cutting, gathering
and dumping. Productivity is increased andoperator
fatigue reduced.

Here’s how it works: On the monitor set the Creep Mode
speed to the percent of maximum machine speed desired.
Hit the creep button on the joystick and fully depress
the forward pedal to move forward at the set speed.
Cut the first tree, cycle the arms; cut the second tree,
cycle the arms, etc. When the head is full, hit the Creep
Mode button again to regain full speed while backing
up, dumping and driving back to the trees. Hit the Creep
Mode button and depress the forward pedal to go back
into Creep Mode and begin cutting again.

• Road Steer Mode: Fast steering is required when working

in the woods, but slower steering is preferable when driving
down a road to a new job site. Road Steer Mode slows
the joystick’s response so the operator can steer the
machine safely to the next site.

Cooling System Air Intake

Engine/Hydraulic Compartment Air Intake – Electric reversing fan pressurizes the engine/hydraulic compartment with cool ambient air

Cooling System Air Exhaust

Aftertreatment Compartment Pressurization

Engine/Hydraulic Compartment Pressurization – Hot air from the engine/hydraulic compartment is pushed out of 3 openings

Pressurized Compartments

For a cooler and cleaner machine

In designing the CSeries, special attention was focused on keeping the machine cool and free of debris. The machine is
segmented into separate compartments that are pressurized to prevent debris from entering. Less debris build-up means less
time required for cleaning it out and better performance. The pressurized airflow keeps electronics, sensors and other key
components cool during long workdays.

Engine/Hydraulic Compartment

The engine and hydraulics are located in a separate compartment at the rear of the machine. An electric reversing fan draws
cool ambient air into the compartment. This forces hot air out of the engine compartment while pressurizing it, preventing
debris from entering and keeping engine electronics and sensors cool.

Cooling Compartment

Removable rubber baffling separates the cooling system from the engine/hydraulic compartment. This prevents the cooling
system from pulling hot air from the engine through the cooler, maximizing the cooler’s efficiency.

Aftertreatment Compartment

The aftertreatment compartment, which contains the Cat Clean Emissions Module (CEM), is pressurized by airflow from the
cooling package. As the air is pulled through the cooling package, the side screens provide resistance and some of the airflow
enters the aftertreatment compartment and forces hot air out while preventing debris from entering thecompartment.

13

Serviceability

Easy ground level servicing to keep you safe

The CSeries is the first and only wheel feller buncher tobe
truly serviceable from ground level. This includes daily service
checks, preventative maintenance, and emergency service.

Engine/Hydraulic Compartment

Large hinged doors at the rear of the machine, along
with hinged doors on both sides and the bottom of the
compartment, provide superior ground-level access to the
engine, hydraulic pumps and key components, including:

• Fuel, air and oil filters

• Starter

• Drive belt

• Water pump

• Alternator

• AC compressor

• Engine oil drain

• Hydraulic hose connections

• Centralized bank of pressure test ports around the pumps

• Engine and pump drive oil level check

Cooling Compartment

Removable rubber baffling and a split side screen protect the
cooling system while making it easy to access for servicing.
Alocking latch on the lower half of the side screen allows
for quick and easy access for cleaning out debris.

Aftertreatment Compartment

The aftertreatment compartment has full three-sided access
to the Cat Clean Emissions Module (CEM) optimizing
service and cleaning access.

Tilting Cab

The tilting cab provides full access to the interior of
themachine, where the two-speed gearbox and hydrostat
are located. You can also access the hydraulic hoses and
electrical harnesses where they enter the center hitch area.
The tilting cab also improves access to clean the machine
andremove the batteries.

Fueling

No more climbing up on the machine, dragging a fueling
hose to fill the tank. The fuel tank is located behind the rear
axle and the fill is at ground level. Simple, easy, safe.

14

Hinged Access

Additional hinged panels are used throughout for easy access
to other components, such as the batteries, hydraulic filters
and strategic bulkheads. All hinged panels are fabricated
of heavy-duty steel for durability and can be completely
removed if desired.

Large hinged mesh screens over the door windows protect
the operator when the sliding windows are open. These mesh
screens swing out to remove debris caught between the door
and screen.

Heavy-duty belly pans are also hinged providing durable
guarding and access to the bottom of the machine for
machine clean out.

Electric Hydraulic Oil Fill Pump

Hydraulic oil is added to the system quickly and easily from
ground level with the standard electric hydraulic oil fillpump
and a quick coupler hose stored on the machine. Oil is pumped
through the filtration system before it enters the tank,
safeguarding the hydraulic system.

Electrical Routing

Electrical harnesses segregate the wiring and connections
within the core systems they support and are bulkheaded
between each system. So, for example, a separate electrical
harness that supports the engine is bulkheaded where it
connects to the cooling package electrical harness. No more
complex, spaghetti wiring. Troubleshooting electrical issues
and replacing wires are greatly simplified.

Just a single, short harness (bulkheaded on both sides)
crosses the center hitch. This harness is protected, making
it much less prone to damage, and is easily replaceable if
necessary. All electrical harnesses are bulkheaded before
theyenter the cab, instead of lines fed in through holes
inthefloor. This keeps the cab quieter.

Hydraulic Hose Routing

The same thinking was applied to hydraulic hose routing.
Strategically placed bulkheads keep hoses short. In the
center hitch, hoses are short and positioned dead center as
they cross through the center hitch, so bending is minimized
asthemachine turns.

Special attention was focused on limiting the number
ofdifferent hose sizes that would be needed in the woods.
Liftarm hoses are all the same diameter and common
lengths are used wherever possible.

Integrated Technologies

Work smarter

Caterpillar offers solutions to help you work smarter.

Machine Troubleshooting

The CSeries machines come with a troubleshooting feature
that allows the operator to drill down and pinpoint the root
cause of a problem, reducing the need for service calls and
holding down costs. The operator can also check the main
hydraulic pump and attachment pump pressures through
the monitor in the cab – a feature unique to Cat wheel
fellerbunchers.

Attachments

Work tool attachments to meet your needs

New work tools have been developed to meet the increased
capabilities of the C Series wheel feller bunchers, including
the new SH-56B, the most versatile and balanced high
capacity bunching saw in the market.

At the heart of each saw attachment is Caterpillar’s field­proven and patented tapered saw shaft and bearing design.
The tapered shaft supports the continual shock loads created
in high cycle applications. Sealed upper and lower bearing
chambers are individually lubricated and vented from the
bottom up.

Highly abrasion-resistant materials are used extensively
inthe saw housing, carry plate, and discharge chute areas to
maximize durability. Many of these areas are reinforced with
additional pieces of replaceable abrasion-resistant material.

SH-56B High Capacity Bunching Saw

The SH-56B excels at cutting and handling high volumes
of small stems, mixed stems and large single stems up to

56.0cm (22.0 in). The saw features Caterpillar’s patented
Strait Grip bunching finger and no-pinch-point tower.

The bunching finger is the most powerful in the industry
andkeeps bunches tightly compressed and straight,
providing excellent productivity in thinning applications.
It also optimizes skidder and loader efficiency because the
stems are well organized. The SH-56B can also handle single
and multiple large stems. The load is carried inside the lift
arms for superior balance, and the no-pinch-point tower
prevents stems from getting caught in the pocket, as is the
case with other high capacity bunching saws. The SH-56B
is also the first saw in the industry to feature tapered roller
bearing joints in the high cycle pin joints of the gathering
arm and bunching finger.

The extended life joints, robust structure and abrasion­resistant materials make the SH-56B an extremely durable,
high capacity bunching saw. Common fittings and only
twohose lengths are used for the SH-56B lift arm hoses.

18

SC-57 Center Post Saw

The SC-57 excels at cutting and handling large single stems
up to 57.6 cm (22.7 in). It also bunches medium and small
stems, making it a versatile saw for thinning through final
harvesting. The gathering arms and tower work together
to grip and tightly hold large single stems and smaller stem
bunches for better control. A single cylinder and link control
the left and right side gathering arms and bunching fingers
simultaneously, improving speed and holding power.

The large, robust structure supports the twisting and bending
loads of large stems on the gathering arms and bunching
fingers created. Chrome plated pins and abrasion-resistant
materials are also used to provide a durable center post saw
for many applications. Common fittings and hose lengths
areused for the SC-57 lift arm hoses.

SS-56 Felling Saw

The SS-56 is a highly versatile saw specially designed
forharvesting large timber. It features a single cut capacity
of56.0 cm (22.0 in), along with small stem accumulation.
Forharvesting larger diameter trees, the SS-56 features the
industry’s only side cut door, a unique solution for harvesting
trees up to 76.0 cm (30.0 in) from a single side on either flat
or adverse terrain. Common fittings and hose lengths are
used for the SC-57 lift arm hoses.
