Tigercat release their L857 feller buncher and LH857 harvester, both built on the new sloping tail platform for steep terrain logging.
Tigercat has released two new track carrier models based on the new sloping tail platform for steep terrain harvesting operations. Both the L857 feller buncher and LH857 harvester are powered by the efficient Tigercat FPT N67 engine. Power is delivered to the track drives via a refined, efficient open loop hydraulic system, providing high tractive effort and excellent performance on steep slopes.
The sloping tail platform takes ground based steep terrain logging to the next level. Optimized weight distribution and low centre of mass, along with Tigercat’s patented super duty levelling undercarriage provide the operator with comfort, stability and confidence on steep terrain. The sloped tail profile provides increased levelling capability to 26 degrees, and better cable clearance in winch assisted applications. For roadside processing applications, the sloping tail with its ability to clear obstacles allows the LH857 to work more effectively on smaller, congested landings.
Other enhancements include further improvements to service access, and in-tank hydraulic filtration for extended service intervals. The side opening engine enclosure completely exposes the engine and most hydraulic components. When open, the enclosure roof serves as a safe, spacious and convenient work platform.
The harvester can be equipped with several Tigercat boom and harvesting head options including the 573 and 575. The feller buncher is well suited to the 5702 and 5702-26 felling saws and 5185 fixed felling saw. Source
The Greasing System is a new optional accessory for Ponsse harvester heads, designed for chainsaw lubrication.
The system feeds grease to the chainsaw from screw-in grease cartridges according to the dosing settings made through the Opti5G information system. Grease cartridges stored in a warm place ensure effective lubrication throughout the work shift.
This is a solution that makes the workday of a forest machine operator easier, especially in cold weather. The grease cartridges replace the fixed grease tank in the harvester head, so you no longer need to pump cold grease from an external container to the harvester head’s grease tank. The cartridge is quick and easy to replace. The cartridges are easy to transport and can be stored in car or cabin.
The lubrication system can hold two 400-gram screw cartridges, which last approximately 8 to 16 hours, depending on the amount of sawing and dosing settings. The dosing settings can be adjusted from the Opti 5G information system according to the situation and need.
The information system notifies the operator when it is time to change the cartridge. The grease cartridge is quick to change, so the machine's downtime is very short. The grease cartridge can be refilled.
Ponsse’s range includes grease cartridges suitable for various needs such as mineral oil-based grease or new biodegradable oil-based grease. The Ponsse Greasing System is currently available for all Ponsse H6, H7, and H8 harvester heads. The Greasing Systems can also be retrofitted. Source
Improved performance and dependability with a redesigned valve block and improved hydraulics for the feeding system.
Both of these improvements contribute to increased productivity and enhanced user experience. For the most part, these are the same upgrades that have been done for the C124, ensuring that both heads align in terms of performance and maintain the same high standards of productivity and quality.
One of the standout enhancements is the new valve bank, which brings increased durability, less wear, and minimized energy losses—contributing to lower fuel consumption. Additionally, the pressure control for the front and rear knives has been optimized for enhanced precision, with all adjustments now fully handled via software. This enables operators to easily configure and maintain the correct pressure settings over time, directly from the cab. The hydraulics for the tilt functions have also been upgraded, providing smoother operation and potentially improving measurement accuracy during processing.
To maintain consistent and high-quality measurements, Advanced Length Measuring is now a standard feature on the C93. This upgrade includes a reinforced cylinder and redesigned mechanics to minimize wear and tear.
The saw unit has been improved with greater clearance between the saw bar and the frame, reducing the risk of collisions. A strengthened, curved base plate increases durability while decreasing the head’s ground footprint. The new design also creates more space around the saw motor, simplifying daily maintenance.
The 2025 model includes several new options and improvements to enhance efficiency and operator convenience. The “Find End” option, for example, streamlines operations by resetting length measurements without requiring a new cut, reducing waste. This feature has been updated with a more robust lens and a debris-resistant design for increased longevity.
A head-mounted, integrated working light—previously available on other C-heads—is now an option for the C93 as well. This light improves visibility, making it easier for the operator to position the head against the tree while also reducing the risk of accidentally cutting into rocks or other obstacles in the forest.
Additional upgrades include more robust bushings with effective sealing for the front delimbing knives. The smaller option for feed wheel motors now has a feed speed of 6 m/s (19.7 ft/s), making it more effective. Together, these updates make the Komatsu C93 a more efficient, durable, and operator-friendly harvesting head, delivering greater productivity and reliability in even the toughest working environments.

The new A30 Electric and A40 Electric are the world’s first serial-produced battery-electric articulated haulers of their size class.
As inventor of the world’s first articulated hauler, it is a natural, yet pivotal, step forward for Volvo CE to create the first electric hauler of its kind. Announced for the first time at Bauma 2025, the A30 Electric and A40 Electric are planned to be available to select customers in Europe from 2026.
Boasting the same unrivalled off-road performance as conventional models, the two new machines are matching zero emissions with world-class hauling for a range of segments including quarrying, mining and construction. With a payload of 29 tons and 39 tons respectively, these machines are now among the largest in Volvo CE’s electric portfolio.
The launch is the latest milestone in a series of hauler innovations. It not only comes 60 years after Volvo CE pioneered the world’s first articulated hauler, but also arrives shortly after the company’s recent unveiling of a new generation of conventional articulated haulers. As part of the company’s largest product portfolio renewal in decades, within which 35% of the company’s total portfolio has been updated, this new generation makeover enjoys improved productivity, safety and fuel efficiency.
Thanks to their powerful lithium-ion batteries, the A30 Electric hauler and A40 Electric hauler are designed to offer a runtime of 4-4.5 hours across most applications, though high-energy jobs may require more frequent recharging. They can even enjoy a runtime of up to seven hours depending on driving conditions. Ideal applications include downhill load carrying and uphill empty runs, tunnel work and quarries and underground operations, where emission reduction is critical.
Fast charging from 20-80% in around one hour is made possible when using a DC charging solution with a maximum charging capacity of 350 kW. What is more, when powered by renewable energy these two machines offer a CO2 saving of 84% (for the A30 Electric) and 90% (for the A40 Electric) across their entire lifecycle, when compared to their diesel equivalents.
A limited volume of A30 Electric and A40 Electric haulers are planned to be available in Europe for select customers from 2026, with increased production in the coming years. Source
