Powertrain

Built for power, reliability, low maintenance, excellent fuel economy and low emissions.

Powerful Performance

The Cat® C9 electronically controlled ACERT delivers power

while meeting all current Tier II emission standards. All

models contain a fuel/water separator, engine air intake heater

and a dual-stage combination air cleaner with pre-cleaner.

High Capacity Cooling System

The side-by-side radiator/oil cooler gives excellent cooling

capacity for high production bunching and harvesting.

On-demand Flexxaire™ fan activates only when required and

allows the cooling fan to purge debris from the radiator area,

keeping a cleaner cooling system. The IQAN control system

infinitely controls blade pitch angle to reduce horsepower

demand from the cooling package, and lower operating costs.

Engine Oil

Caterpillar engine oil is formulated to optimize engine life and

performance and is recommended for use in Cat diesel engines.

The engine oil change interval has been increased to 500 hours.

Service

The clamshell engine compartment provides easy access to

oil filters, oil dipstick, hydraulic fill pump and hoses reducing

maintenance time.

Low Exhaust Emissions

The Cat C9 ACERT engine is a low emission engine designed

to meet US EPA off-road Tier II emission regulations.

Page 4

Hydraulic Packages

Powerful hydraulic system combined with a powerful boom and

stick maximize productivity in any felling or harvesting job.

Electric Hydraulic Oil fill Pump

The hydraulic oil site gauge provides easy visibility to know

when hydraulic oil needs to be added. An easy accessible

service wand allows hydraulic oil to be pumped through the

hydraulic filtering system and into the tank. This reduces

maintenance down time and helps to maintain oil cleanliness

requirements.

Variable Displacement Pump

All Cat® 500 series FTS Track Feller Bunchers are equipped

with 200 cc variable displacement pump for travel, a 200 cc

boom and implement functions, and a dedicated 55 cc variable

displacement pump for felling attachments. Optional hydraulics

for dangle harvesting or processor heads and intermittent

saw heads are available for all models.

Caterpillar® Hydraulic Oil

Provides maximum protection against mechanical and corrosive

wear in all hydraulic systems. It’s high zinc content reduces

wear, and extends pump life. Provided certain requirements are

met (e.g. S-O-SSM analysis every 500 hours), the hydraulic oil

change interval is extended from 2,000 hours to 4,000 hours.

Biodegradable Hydraulic Oil

The optional biodegradable hydraulic oil (HEES) is formulated

to provide excellent high-pressure and high-temperature

characteristics and is fully compatible with the all hydraulic

components. HEES is fully decomposed by soil or water

microorganisms, providing a more environmentally-sound

alternative to mineral-based oils.

ToughGuard Hoses

Abrasion resistant hoses along the boom and stick provide

strength and flexibility. The ToughGuard cover consists of a

thin layer of UHMW polyethylene bonded to the rubber cover,

providing exceptional abrasion resistance. In many applications,

it eliminates the need for external guarding.

Operator Comfort

The interior layout maximizes operator space, provides exceptional comfort and reduces operator fatigue.

IQAN

IQAN display allows the operator

to continuously monitor the

operating systems of the machine.

This provides early warning for

potential problems, and allows the

operator to adjust control parameters maximizing performance

and productivity.

Control Convenience

Each control is placed within easy

reach of the operator. Joysticks

control the implement and

attachment functions, providing

Viewing

Cab design optimizes post structures and window placement

to provide excellent operator visibility to front, sides and rear.

Standard 1.25" thick “Margard” front window maximizes

operator protection. All purpose

built forestry cabs are designed

with heavy-duty guarding, meeting

FOPS/ROPS/OPS requirements.

Fresh Air

Large sliding side window with

screen to allow fresh air into cab.

easy operation.

Foot Pedals

Ergonomically located pedals with

side-by-side foot rests provide for

maximum operator comfort while

operating machine travel.

Skylight

A unique large polycarbonate

skylight provides excellent

upward visibility, and acts as an

alternate escape hatch.

Interior Operator Station

The operator station is

quiet with conveniently

placed controls, joysticks

and an ergonomically

designed seat reducing

operator fatigue.

Quiet Operation

Isolation mounted cab and engine reduces sound levels and

vibration for quiet and comfortable operation.

Large Storage Compartment

A large storage space behind the seat, provides

sufficient room for a lunch box, hard hats and work tools.

Electrical System

24-volt electrical system with

in-cab 24-12 volt converter,

dual in-cab 12 volt power points and one 24 volt power point.

may be selected to provide two additional batteries, a HD starter,

and HD cables.

Page 6

Leveling System

Tilting mechanism provides stability and

comfort in steep slope conditions.

Tilt Mechanism

With the most robust tilt mechanism in the industry, the

FTS 552 tilter has a patented 3-cylinder tilt mechanism with

simultaneous tilting forward and side-to-side. Trunion cylinders

are mounted on 2" (51 mm) steel plates and transfer vertical

loads down to the interface of the track frames and carbody,

putting the load into the track and ground.

Cylinders

Three-cylinder tilt mechanism with simultaneously

20 degree forward tilt and 11 degree side-to-side tilt.

Ground Clearance

FTS machines have excellent ground clearance and

open carbody design. This provides increased mobility

by eliminating debris interference and other obstacles

encountered in rugged working conditions.

Page 7

Undercarriage

High quality custom engineered, heavy duty forestry undercarriage.

Reliable

Precision welded, high-wide carbody has strong frames that

reduce flexing and increase reliability of rollers and track

links throughout the life of the machine. Nine bottom rollers

per side.

Travel Motor

Proven final drives and travel motors provide up to

104,000 lb (47174 kg) of tractive effort on the 552 giving

excellent traction and power to the ground.

Track Guards

All models contain bolt-on track guards.

Carbody

Leveling 552 model features a bolted track frame to

carbody design. This provides a standard gauge width,

or allows adjustment to a wide gauge width to improve

machine stability, and increase productivity on steep slope

applications.

Page 8

Boom and Stick

Designed for maximum reach and lift capacity.

With up to 21,800 lbs (9400 kg) of bare pin lift capacity at

21.5' (6.6 m) on the 552 track feller buncher (with the

standard linkage), the 500 series machines are dominant

over competitors in their size classes. With market leading

lift capacity, 28.8' (8.6 m) of reach, and tight stick tuck-in

capabilities, these machines deliver high performance felling in

all applications. The 552 track harvester delivers the same high

performance with 12,500 lbs (5700 kg) of bare pin lift capacity

and 37' (11.3 m) of maximum reach, while the 552 long felling

linkage delivers 16,900 lbs (7700 kg) of bare pin lift capacity at

32' (9.7 m).

Versatility

Caterpillar® disc saw attachments are available to meet felling needs.

Attachments

From plantation thinning to select cut of large diameter

wood, Cat felling attachments provide reliable productive

felling solutions. These range in cut capacity from 22" to

24". Designed to allow maximum visibility of the cutting

area, all saws utilize high pressure hydraulics for fast saw

recovery and quick arm speed. This provides a positive

impact on production and better tree control.

Tilt

All models are available with a standard 40 degree partial

lateral tilt, or an optional 220 degree full lateral tilt.

Owning and Operating Costs

Cat provide the best value for your operation.

ACERT Technology Fuel Economy.

Based on Caterpillar

engines with ACERT technology is 3 to 5 percent better

than current competing technologies. This fuel economy

is directly related to the complete combustion of fuel

due to the integration between the electronic control that

monitors conditions, the air management system that

controls air volume and the fuel injection system that

delivers just the right amount of fuel as needed.
