522B
The new B Series track feller bunchers feature smoother hydraulic performance, increased engine HP, a more comfortable operator station and better right side operator visibility. The 522B Series are zero tail swing machines designed for medium to high production clear cut and or select cut on rough terrain. These machines perform in a variety of small through larger tree size applications. The 522B model is a leveling machine for more comfort on steep terrain. A robust undercarriage utilizes proven components, customized for demanding forestry conditions. The unique boom design provides industry leading lift capacity throughout full reach range, a benefit in large timber.

BENEFITS & FEATURES
Power Train
Powerful Performance
The Cat C9 electronically controlled ACERT engine delivers power while meeting all current U.S. EPA emission standards. All models contain a fuel/water separator, engine air intake heater and a dual-stage combination air cleaner with precleaner.
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 automatically adjusts the Flexxaire fan blade angle, reducing horsepower demand and lowering fuel consumption. The purge cycle frequency and duration can be set by operator in the cab to suit varying application conditions.
Engine Oil
Cat engine oil is formulated to optimize engine life and performance and is recommended for use in Cat diesel engines. Extended oil change intervals reduce maintenance and machine downtime.
Service
The clamshell style engine compartment provides easy access to all filters, oil dipstick, coolant reservoir, hydraulic fill pump, valves and hoses reducing maintenance time.
Low Exhaust Emissions
The Cat C9 ACERT engine is a low emission engine designed to meet U.S. EPA emission regulations.
Batteries
An optional starting aid for colder climates is available for 522B machine models. This option provides two (2) additional batteries and HD battery cables.
Hydraulic Packages
Electric Hydraulic Oil Fill Pump
An easy accessible service wand allows hydraulic oil to be pumped through the hydraulic filtering system and into the tank. This reduces maintenance downtime and helps to maintain oil cleanliness requirements.
Variable Displacement Pump
522B track feller bunchers are equipped with variable displacement pumps for travel and implement functions. Optional hydraulics for dangle harvesting or processor heads are available for all models.
Cat Hydraulic Oil
Provides maximum protection against mechanical and corrosive wear in all hydraulic systems. Its high zinc content reduces wear and extends pump life. Biodegradable hydraulic oil (HEES) is also available from your Cat dealer and provides an 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.
Operator Station
Operator Comfort
The operator station is designed with joysticks and an air ride seat, reducing operator fatigue and providing easy operation. An HVAC system with updated air ducts provides better cooling and heating. A large side window with side screen allows fresh air into the cab, and an isolated mounted cab and engine reduces noise levels and vibration. Ergonomically located pedals with side-by-side foot rests provide operator comfort while operating machine travel.
Visibility
The cab design optimizes post structures and window placement to provide excellent operator visibility to front, sides and rear. A large polycarbonate skylight provides excellent upward visibility.
Safety
The standard 32 mm (1.25 in) thick “Margard” front window maximizes operator protection. All purpose built forestry cabs meet FOPS/ROPS/OPS/WCB, OR-OSHA requirements. The skylight provides an alternate escape hatch.
Monitor
The IQAN MD3 display allows the operator to continuously monitor the operating system of the machine. The monitor has been downsized slightly to improve the operator's line of sight out the right front corner of the cab. The IQAN control system allows the operator to adjust all control parameters.
Electrical System
The B Series track feller bunchers feature dual in-cab 12 volt power points and one 24 volt power point. Power is provided by two 12 volt maintenance free batteries and 95 amp alternator. An optional cold weather starting attachment may be selected to provide two additional batteries and HD starter cables.
Leveling System
Tilt Mechanism
With the most robust tilt mechanism in the industry, the 522B tilter has a patented 3-cylinder tilt mechanism with simultaneous forward and side-by-side tilting. Trunnion cylinders are mounted on 51 mm (2 in) 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
A three-cylinder tilt mechanism features simultaneously 21 degree forward tilt and 11 degree side-to-side tilt.
Ground Clearance
The 522B machines have excellent ground clearance of 889 mm (35 in) and open carbody design. This provides increased mobility by eliminating carbody interference with large stumps, rocks or other obstacles.
Undercarriage
Undercarriage
522B Series machines utilize larger 330 size components providing extended life and reduced O&O costs.
Travel Motor
The proven final drives and travel motors provide up to 34 246 kg (75,500 lb) of tractive effort as standard on the 522B, giving excellent traction and power to the ground. An optional High Drawbar final drive is available on the 522B model providing increased tractive effort of 38 555 kg (85,000 lb). Three (3) travel speed range selections are standard.
Track Guards
All models feature full length track guards to maximize shoe support in all types of terrain.
Carbody
The 522B model features a bolted track frame to carbody design. This provides a narrower gauge width, or allows adjustment to a wider gauge width to improve machine stability, and increase productivity on steep slope applications. The 522B provides maximum ground clearance and a smooth carbody under-surface to resist snagging on debris or large obstacles. The precision welded track frames reduce flexing and increase the durability of rollers and track links throughout the life of the machine.
Carrier Rollers
B Series models offer a choice of either standard single flange carrier rollers for moderate terrain and warm climates or star carrier rollers for severe terrain and cold climate applications. Nine bottom track rollers are used per side.
Boom and Stick
Boom and Stick
The track harvester configuration delivers the same high performance with 4000 kg (8,800 lb) of bare pin lift capacity and 9.9 m (32 ft 6 in) of maximum reach.
Sustainability
The B Series track feller bunchers are designed to maximize efficiency and productivity while conserving natural resources.
- The C9 ACERT engine meets all current U.S. EPA emission standards.
- The IQAN control system automatically adjusts the Flexxaire fan blade angle, reducing horsepower demand and lowering fuel consumption.
- Major structures and components are built to be rebuilt, reducing waste and replacement costs.
Serviceability
Extended Service Intervals
Caterpillar service and maintenance intervals have been extended to reduce machine service time, increase machine availability and reduce operating costs. Hydraulic oil change intervals can be extended from 2,000 hours to 4,000 hours. Engine coolant change intervals are 12,000 hour with Cat Extended Life Coolant/Anti-freeze. Regularly scheduled maintenance extends machine service life and lowers overall operating costs. 500-hour oil change interval reduces overall maintenance costs.
Flexxaire Fan
Standard Flexxaire fan automatically adjusts the fan blade pitch to optimize cooling and reduce fuel consumption. The reversing purge debris cycle frequency and duration can be set by operator in the cab to suit varying application conditions.
Clam-Shell Service Door
The hydraulically actuated clam-shell service door provides easy and quick access, reducing maintenance downtime.
