The Tigercat harvesting head product range continues to gain momentum globally as more contractors opt for the full Tigercat base machine and head set-up.

The Tigercat harvesting head product range continues to gain momentum globally as more contractors opt for the full Tigercat base machine and head set-up.

There are many advantages having the base machine and head from the same manufacturer. The head can be installed at the factory, which creates efficiencies, reduces lead times and freighting costs. Having one point of contact for all maintenance and service work is another key advantage that makes the day-to-day operations for Tigercat owners easier and more efficient.

User-friendly D5 Control System

The D5 system combines field-proven hardware and bucking (cross-cutting) control with a simple and intuitive Tigercat-developed user interface. Available on three levels of control and reporting, the D5 system handles multiple jobs with multiple operators, and allows for customising menus and settings, right down to joystick button functions. Over 70 operator specific parameters are available to tailor controls to each operator’s preferences. The clean and easy to follow layout of the touch control screen allows the operator to make adjustments as easily as using a smartphone or tablet.

RemoteLog for off-site access

RemoteLog provides machine monitoring and fleet management in real-time without need for a cellular signal. The RemoteLog data includes;

• Geographic location

• Satellite based text messaging

• Activity timeline

• Production metrics summary

• Diagnostics

• Fuel levels and consumption

• Mechanical data

• Analytics

Late last year Tigercat released new RemoteLog features including a new diagnostics dashboard where mobile users can easily review machine fault codes grouped in cards and colour coded by severity. Office personnel may view fault codes in an easy to sort and filter list. A single click brings up technical information for any fault code. The easily accessible engine troubleshoot guide gets you the answer you need quickly.

A new machine summary report was released with a new one-stop machine summary report being sent to the user weekly. It contains data such as operating time, production metrics, total fuel consumption, fuel rates, engine hours, machine utilisation, and summary of fault codes.

The offering provides enhanced machine management with easy access to the control software version running on the machine. Check telematics firmware version to see if it needs to be updated and quickly find your primary dealer contact.

Lastly the new production metrics can track how much you are producing with your machines. Mulchers now reporting mulched land area, harvesters and processors report production volumes and stem counts while forwarders report number of loads.

More improvements were released in April this year with a RemoteLog web service. You can now access the ‘Data that Matters’ from RemoteLog directly through a new web service using your IT servers. Now it is possible to share geographic position and production data for your machines with whomever the machine owner wants, such as landowners and forestry operations companies. RemoteLog utilises the well documented ISO 15143-3 (AEMP 2.0) Web API that is widely used in mobile machinery applications.

Direct on-site telematics via LogOn

LogOn is an on-board system that gives access to on-site telematics using a secure Wi-Fi hot spot. It gives the user quick access to the following data;

• Detailed activity chart

• Stem count and production volume

• Detailed failure cause and repair information

• Easy firmware updates with the Tigercat Mobile App update manager

• Access to operator and service manuals

Updates were also introduced for LogOn reports in April this year - You can now easily view production, activity timelines, and fuel consumption on your mobile device using LogOn at the worksite. Formatted reports in PDF or CSV formats are now downloadable to save to your mobile device. Reports can be viewed anytime or shared through email.

Tigercat harvesting head range

Tigercat harvesting heads are designed and built to match the high-performance capabilities of Tigercat tracked and wheeled carriers and are well suited to a variety of jobs including at-the-stump harvesting, roadside processing and debarking.

The range of Tigercat harvesting heads now includes a 575, 570 and 568 model.


The 575 (23”) is a heavy-duty harvesting head specifically designed to match the high-performance capabilities of Tigercat carriers.

With independent knife arms, the 575 harvesting head excels in tough timber with large limbs and poor stem form. Optional timed knives are available for easier picking in roadside processing applications.

The 575 harvesting head is productive and reliable in a variety of demanding applications and tree profiles. An extremely durable all-around harvester head, it is well suited to in-stand harvesting, roadside processing, multi-stem pulpwood processing and eucalyptus debarking.

Tigercat’s patented Autoshift™ drive system provides extra power and positive grip when feeding large trees, fast speed in smaller trees, and full manual control when required. The 575 starts in 3WD, maximizing feed force for faster acceleration and to quickly power through bigger trees. As the load drops, it automatically shifts to 2WD, improving efficiency and increasing feed speed. The system shifts back and forth seamlessly with no operator input required, all while maintaining precise and accurate length measurements.


The 570 (20”) is most productive working with trees 15-50 cm (6-20 in) in diameter in softwood and hardwood stands. Although best suited to the Tigercat H845 series, the 570 is designed to work with the H822, and H855 carriers. With optional hydraulically timed processor knives, the 570 can also be used for roadside processing. The 570 has recently proved itself beneficial in debarking eucalyptus.

The wheel arms, pins, bushings, cylinders, feed motors and rotator are shared with the 575 model for proven strength and long life. The chassis is designed for optimum strength-to-weight with focus on visibility, component protection and quick service access. A new integrated valve package enhances performance and service access with fewer hoses and connections to improve reliability. Clean electrical routing with common service parts further increases up-time.

An optional top-saw is available for the 570 giving it more versatility. The top saw housing is integrated into the saw chassis, providing optimum head balance, weight, and structure.

The 570 harvesting head is optimal for superior feeding, delimbing, measuring and debarking, especially in sub-optimal stem form conditions. Available on three levels of control and reporting including full optimizer and StanForD reporting capability and Geo Mapping, the D5 system handles multiple jobs with multiple operators, and allows for customizing menus and settings, right down to joystick button functions.


The latest addition to Tigercat’s line of harvesting heads is the 568 (22”). The new 568 harvesting head is a robust, high performance head designed for tracked carriers. It is best suited for roadside processing applications, particularly in tall straight softwood, or hardwood with fewer limbs in the 15-55 cm (6-22 in) range.

With timed knife arms and triangulated wheel arms, the 568 can quickly pick and maintain positive tree contact and control. The patented 4WD - 2WD auto-shift drive system provides extra power and positive grip when feeding large trees, fast speed in smaller trees and full manual control when needed.

Knife arms feature double-edged, replaceable blades with optimal contour for clean delimbing.  The front floating knife with spring preload follows the contour of the tree further enhancing delimbing performance.  Single or dual-track length measuring wheels and dual diameter encoders assure superior measuring accuracy.

Other features of the 568 include optional conventional boom or through-tip boom continuous rotation, laser diffuse, or through-beam find end sensors, colour marking and various feed wheels.

“Several of the Tigercat heads are now working in Australia in various applications and species. We are very encouraged by the feedback from the contractors that are reporting improved production and ease of maintenance. We are confident the Tigercat harvesting heads will result in a lower cost per tonne than competitor heads well into the future”, says David Hazell, Managing Director at Onetrak – the national dealer for Tigercat in Australia.
