Weiler Forestry
Weiler Forestry have been busy growing their product offering including a new full tail swing, flat bottom and leveling feller buncher and harvester platform.
The company says that the new 700 Series is industry leading in all the key performance criteria important for extreme logging operations including swing, lift capacity, tractive effort, tilting range and overall multi-functioning.
Running a C9.3B Cat engine rated at 375 hp, the B768 and H768 are described as having unmatched performance capability. The optimized hydraulic system consists of eight dedicated pumps, and was designed specifically to maximize efficiency in feller buncher applications. Closed loop drive and closed loop swing offer excellent multi-functioning capability and facilitate smooth, efficient and fluid machine operation, says the company.
Weiler also offers a reduced tail swing B458A machine. Now at 330 hp, this machine has updated travel and multi-functioning capabilities. With the longest track frame in the industry with 11 bottom rollers, the B458A extended frame is described as a very stable mid-sized machine.

Tigercat
Tigercat is a world leader in steep slope harvesting and extraction systems. For over 20 years, it has been at the forefront of steep slope innovation, with products such as six-wheel-drive rear bogie skidders, leveling shovel loggers, the 5195 directional felling head, the 180 swing yarder and the 120 winch assist.
One of the latest developments is the new LX877 feller buncher, a machine that can achieve even higher performance and productivity on steep slopes, and has enhanced leveling capabilities. Building on the highly successful LX870D platform, the LX877 re-imagines what a steep slope carrier should be, says Tigercat.
The sloping profile of the upper assembly allows for increased track clearance resulting in greater leveling capability equal to Tigercat’s near-zero tail swing LX830E. The sloping rear also results in superior cable management for winch assisted applications.
The leveling structure itself is constructed with thick steel cylinders, pins, and bushings. When combined with long track frames and wide stance carbody, the leveling system’s clever geometry optimizes balance and weight distribution, improving comfort and confidence on sloped terrain, says the company.
Eltec
Eltec, a leading forestry harvesting equipment manufacturer in Canada, says that it has raised the bar with its latest innovation in leveling systems. Its cutting edge technology now offers quicker and smoother transitions, revolutionizing the operator experience.
At the heart of this advancement is its improved flow sharing valve system, engineered to enhance precision and responsiveness. This upgrade allows for seamless operation on even the steepest slopes, maintaining optimal operator positioning whether climbing or descending challenging terrain.
Eltec says that its proprietary leveling systems are now more responsive and self-adjusting than ever before. In combination with its heavy-duty rotation system, the tilt angle of the levelers keeps the cab horizontal, ensuring operator comfort and safety.
Designed by loggers for loggers, Eltec says that its machines continue to be the workhorses of the forestry sector and encourages loggers to experience the difference of its enhanced leveling technology—boosting productivity, reducing operator fatigue, and conquering the toughest terrains with ease.
John Deere
The John Deere 959M tracked feller buncher has been upgraded with new operator assistance features and durability enhancements, reinforcing its reputation as a top performer in steep and demanding forestry environments.
A key update is the Dedicated Travel System, now standard on the 959M, which isolates travel functions from boom and swing operations, allowing for smoother, uninterrupted movement and increased efficiency.
The Return-To-Level functionality, part of the optional Slope Management System, enables operators to automatically level the rotating upper structure with a single button press, reducing workload and improving stability on uneven terrain. This pairs with the John Deere Slope Monitoring system, which displays real-time terrain slope data.
John Deere says that the 959M maintains its industry-leading leveling system, offering 26 degrees of forward tilt, 14 degrees rear tilt, and 7 degrees of side-to-side tilt. Upgraded cylinder pin joints and reinforced track frame steps further improve durability, ensuring long lasting performance in the toughest conditions.
TimberPro
The TimberPro D-Series has leveling capabilities and has been fitted out with a new larger cab that has improved visibility, both out the front of the cab as well as the boom side.
The leveling system is capable of tilting 28 degrees to the front, 7 degrees to the rear and 24 degrees to the side.
It is also now equipped with high output LED lighting that will increase night time visibility in both the work area as well as directly under the cab to illuminate the tracks. The last major refinement of the cab is the addition of a digital climate control system to keep the cab temperature steady and comfortable.
The Cummins L9 Performance Series Stage V engine contains an EGR-free architecture and compact Single-Module after-treatment system.
The new L9 engine also boasts increased fuel economy and longer maintenance intervals over the previous models, that contributes to a reduced cost of operation and lower overall total cost of ownership, says the company.
