Introduction
In the forestry industry, adaptability and efficiency are paramount. One innovative approach to enhancing felling operations involves integrating the Hultdins 850 Super Fell Head onto a Timberjack 950 Feller Buncher. This combination aims to leverage the strengths of both machines, offering improved productivity and versatility in harvesting operations.
Understanding the Equipment
To successfully integrate the Hultdins 850 onto the Timberjack 950, several technical aspects must be addressed:
A logging crew faced challenges with dense underbrush and uneven terrain, which hindered the efficiency of their traditional hot-saw setup. By retrofitting a Timberjack 950 with a Hultdins 850 head, they achieved significant improvements in productivity. The ability to switch between the hot-saw and felling head allowed them to adapt to varying conditions, reducing downtime and increasing overall efficiency.
Conclusion
Integrating the Hultdins 850 Super Fell Head onto a Timberjack 950 Feller Buncher presents a viable solution for enhancing felling operations. By addressing hydraulic compatibility, control systems, and mechanical interfaces, this integration can lead to improved productivity and versatility in the field. However, careful planning and execution are essential to overcome the associated challenges and ensure the success of the retrofit.

Understanding the Equipment
- Hultdins 850 Super Fell Head: A high-performance felling head known for its robust design and efficient cutting capabilities. It requires approximately 50 GPM at 4700 PSI for optimal saw function.
- Timberjack 950 Feller Buncher: A powerful tracked machine equipped with multiple hydraulic pumps, including a main pump delivering 146 GPM at 5400 PSI, a saw pump at 30 GPM, and a head function pump at 20 GPM.
To successfully integrate the Hultdins 850 onto the Timberjack 950, several technical aspects must be addressed:
- Hydraulic Compatibility: The Timberjack 950's hydraulic system must be adapted to provide the necessary flow and pressure for the Hultdins 850. This may involve adding a section to the main or carrier valvebody and rerouting oil from the main pump to the saw and tilt functions of the head.
- Control Systems: Implementing an electric-over-hydraulic valve system can facilitate the operation of the saw and tilt functions. A three-way rocker switch combined with a two-way toggle on the joystick can be used to control these functions, mimicking the original Hultdins control setup.
- Mechanical Interface: Fabricating a custom knuckle to mount the Hultdins 850 head onto the Timberjack 950's heel rack is essential. This ensures a secure and stable attachment, allowing for efficient operation.
- Hydraulic Flow Management: Ensuring that the Timberjack 950's hydraulic system can supply the required flow and pressure without compromising other functions is crucial. Careful planning and possibly upgrading certain components may be necessary.
- Weight Distribution: The additional weight of the Hultdins 850 head can affect the balance of the Timberjack 950. Proper weight distribution and possibly adding counterweights can mitigate this issue.
- Control Integration: Integrating the control systems of the Hultdins 850 with the Timberjack 950's existing systems requires meticulous wiring and calibration to ensure seamless operation.
