Hydraulic Horsepower
Hydraulic horsepower is the actual machine power available to do work through implements and work tools. It's much more than just the engine power under the hood - it's a core strength that differentiates Cat® machines from other brands. In fact, hydraulic horsepower for the 568 increased from the previous series' output due to pump and other system improvements. This translates into moving more material in less time.

Main Control Valve and Auxiliary Valves
The 568 uses a high-pressure system to tackle the toughest of work in short order. A new one-piece, cast-block, back-to-back main control valve features resized and reshaped oil passages to improve efficiency and serviceability; stackable auxiliary valve attachments mount on top of the main valve, which allows for auxiliary hydraulic lines and valve configurations to be simplified for greater reliability.

Return Filter
The return filter is a capsule-type design with a cartridge inside. Unlike many competitors' offerings, the Cat cartridge features a handle to help remove and change without oil spillage or contamination. A sensor attached to the filter warns the operator if it is plugging or exceeds a certain pressure level.

Swing Priority Circuit
The swing priority circuit on the 568 uses a new electric valve that's operated by the machine's improved Electronic Control Module (ECM). Compared to using a hydraulic valve, an electric valve allows for more finely tuned control, which is critical during material loading.

Electric Boom Regeneration Valve
A new electric boom regeneration valve minimizes pump flow when the boom lowers down, which improves fuel economy. It is optimized for any dial speed setting being used by the operator, which in turn aids controllability and enhances component durability.

Stick Regeneration Circuit
The 568 regenerates the flow of oil from the rod end of the stick cylinder to the head end of the stick cylinder during low-load, stick-in operation - an approach that saves energy and expense.

Operator Station

A new seat range includes air suspension, heated standard, and heated and air cooled option. Each seat includes a reclining back, upper and lower seat slide adjustments, and height and tilt angle adjustments to meet operator needs for comfort and productivity.

The right and left joystick consoles can be adjusted to meet the operator's desired preference, making him (or her) more comfortable and productive during the course of a day. With the touch of the button, one-touch idle reduces engine speed to help save fuel; touch it again or move the joystick and the machine returns to normal operating level. The optional heavy lift mode increases machine system pressure to improve lift - a nice benefit in certain situations. Heavy lift mode also reduces engine speed and pump flow in order to improve controllability.


The 568 is equipped with a new LCD (Liquid Crystal Display) monitor that's 40% bigger than the previous model's with higher resolution for better visibility. In addition to an improved keypad and added functionality, it is programmable to provide information in a choice of 42 languages to support today's diverse workforce. A new “Engine Shutdown Setting” accessible through the monitor allows owners and operators to specify how long the machine should idle before shutting down the engine, which can save significant amounts of fuel.


MP3-Ready Radio and Power Supply
The standard radio is equipped with a new auxiliary audio port for MP3 players. Two 12-volt power supply sockets are located near key storage areas for charging.

Storage spaces are provided to the front and rear of the right-side console to hold small items.

Automatic Climate Control
An updated climate control system helps provide a comfortable working environment in the 568. Improved AC ducting provides increased airflow and operator comfort. A standard sun screen provides reduced sun glare and heat build up in cab.


Cat® C9.3 ACERT™ Engine
The C9.3 ACERT engine delivers more horsepower using less fuel than the previous series engine.

Emissions Solution
The C9.3 ACERT engine is equipped to meet current Tier 4 Interim emissions standards. Driven by customer input, Cat aftertreatment regeneration solution ensures the machine works as normal with no operator intervention needed. The machine comes with two programmable modes of operation: automatic and manual regeneration. In automatic mode, the machine starts the regeneration process once the filtering system reaches a certain level and conditions are optimal. The system will not interrupt the work process and can regenerate during machine operation. Manual mode enables the operator to override the automatic mode. With a touch of a button (1) inside the cab, this mode allows the operator to move the machine from sensitive work areas before initiating the regeneration process.

Emissions Solution

Bio Diesel-Ready Fuel System
The C9.3 ACERT engine is equipped with a high-pressure common rail fuel system that includes a new electric priming pump and three-layer fuel hose to allow the use of bio fuel up to B20 (bio fuel 20% mixture).

Cooling System
The high-ambient cooling system features side-by-side-mounted radiator and oil and air coolers for easy cleaning and a new Flexxaire variable pitch, auto reversing fan for enhanced energy efficiency as standard equipment.

Speed and Power Control
The new 568 features isochronous speed control to maintain a constant speed - regardless of load - to improve fuel economy. Three different power modes are offered: high power, standard power, and economy power. The operator can easily change between modes through the monitor or console switch to meet the needs for the job at hand - all to help manage and conserve fuel.

Structures and Undercarriage

The upper frame includes new reinforced mountings to support the Roll-Over Protective Structure (ROPS) cab; the lower frame is reinforced to increase component durability.

A longer undercarriage system provides added stability in the most demanding applications. Heavy-duty track rollers, and carrier rollers, press-fit pin master joints, and enhanced track shoe bolts improve durability and reduce the risk of machine downtime and the need and cost to replace components. A new full length guiding guard maintains track alignment and improves performance and undercarriage life in multiple applications. A redesigned motor housing prevents mud packing and debris buildup around seals.

Two counterweight options are available for General Forestry: 6.0 MT and 8.3 MT. The 8.3 MT counterweight is standard on the Log Loader configuration. Each is designed to match the height of the machine, and each comes with new integrated links that enable easy removal for maintenance. Regardless of choice, counterweights are bolted directly to the main frame using four M36 bolts for rigidity.

Front Linkage

Booms, Sticks and Heels
The 568 offers both General Forestry and Log Loader booms and sticks. Each is built with internal baffle plates for added durability, quality and reliability. Large box-section structures with thick, multi-plate fabrications, castings, and forgings are used in high-stress areas to improve durability.

Booms, Sticks and Heels

There are two General Forestry, two Log Loader boom and stick, and three heel options available to match a variety of forestry applications. There is also a DB-Family Bucket Linkage available for the General Forestry configurations.

Work Tools

Work Tools
An extensive range of tools can be fit up to the 568 includes grapples, buckets and thumbs. Each is designed to optimize the versatility and performance of your machine.

A thumb control group can be fit up to the General Forestry, and Butt-n-Top and Power Clam hydraulics can be installed on the Log Loader. Several different boom and stick line groups are available as options on the 568 for running various work tool attachments.

GLL Logging Grapples
The Cat brand offers a complete line of shovel and loading grapples. These are available in 52", 55" and 60" sizes to meet a range of application requirements.

GLL Logging Grapples

Cat buckets are designed for better performance. The leading edge has been pushed forward, resulting in more efficient filling and better operator control for greatly improved productivity. Wear coverage in the corners and side cutter and sidebar protector coverage are improved; a new lift eye design accepts a wide range of shackle sizes.


Quick couplers allow one person to change work tools in seconds for maximum performance and flexibility on a job site. One machine can move rapidly from task to task, and a fleet of similarly equipped machines can share a common work tool inventory.


Integrated Technologies

Electric Boom and Stick Regeneration Valve
The 568 features unique electric boom and stick regeneration valves. The valves use gravity during typical “boom down” or “stick in” operations to regenerate flow of oil from the head end of the cylinder to the rod end of the cylinder instead of sending it all the way back to the hydraulic tank. This distinct Cat solution increases efficiency and reduces cycle times and pressure loss for higher productivity and lower fuel costs.

Main Control Valve
The 568 uses a high pressure hydraulic system as standard. It is a one-piece, cast-block, back-to-back (BTB) control valve, improving efficiency and serviceability versus the previous series machines. Auxiliary valves are stackable and mounted on top of the main valve, which simplifies, and leads to greater reliability. Fuel consumption is reduced by re-sizing and shaping of the oil passages inside the new BTB valve.

Flexxaire Auto-Reversing Fan
The cooling system's new variable pitch reversible fan is controlled by hydraulic temperature, coolant temperature, and ATAAC charge air temperature in different ambient conditions to optimize cooling. The fan has a pitch sensor that is controlled by the Electronic Control Module (ECM).

Cat Product Link*
This deeply integrated machine monitoring system is designed to help customers improve their overall fleet management effectiveness. Events and diagnostic codes as well as hours, fuel consumption, idle time, machine location, and other detailed information are transmitted to a secure web based application called VisionLink™, which uses powerful tools to communicate to users and dealers. *Product Link licensing is not available in all areas. Please consult your Cat dealer for availability.


Ground-Level Maintenance
The machine is designed to accommodate servicing most maintenance items from the safety and comfort of ground level.

Service Doors
Wider, taller service doors feature sturdier hinges and latches and a new slotted hole vent design to prevent debris entry; a new one-piece hood provides easier access to the engine and cooling compartments along with a new hood screen design to prevent debris entry.

Service Doors

The radiator, pump, and air cleaner compartments provide easy access to major components. When an air cleaner plugs, a warning is displayed on the monitor inside the cab.

Other Service Improvements
The water separator with water level sensor has a primary fuel filter element located in the pump compartment near ground level; the electric priming pump is mounted on the primary filter base and is more reliable and easier to service than traditional hand-priming pumps. The engine oil check gauge is situated in front of the engine compartment and is easy to remove. The engine oil filter is situated in the pump compartment for easy access. Changing engine oil is simple due to a drain cock designed to prevent spills. The 568 has two fuel tanks as standard equipment, reducing refill intervals. Drain cocks are provided to make it easy to remove water and sediment during maintenance.


Reinforced Frame
The upper frame is reinforced to accommodate the ROPS cab.

Sound Proofing
Improved sealing and cab roof lining help lower noise levels during machine operation.

Anti-Skid Plates
The surface of the upper structure and the top of fuel tank area are covered with anti-skid plates to help prevent service personnel and operators from slipping during maintenance.
