Next generation Tigercat feller bunchers come with major upgrades for the operator.
The Tigercat H-series feller bunchers are set to enter regular production beginning October 2025. The three-model line-up includes the 720H, 724H and 726H. The wheelbase of all three machines has been increased by 4.5 in (115 mm) and the physical size of the 720H and 724H remains identical. The increased wheelbase, along with a built-in 900 lb (410 kg) rear bumper, improves handling and stability while decreasing the turn radius for increased agility in tight stands.
The primary differentiator between the three models is engine horsepower. When equipped with the Tigercat FPT N67 Tier 4f engine, the 720H is rated at 203 hp (151 kW), the 724H is rated at 246 hp (183 kW), and the 726H is rated at 285 hp (212 kW).
The common operator’s cabin has been completely redesigned with increased interior volume, resulting in more legroom, additional storage and a roomier feel. Operator sightlines have been improved with a front windshield that is 27% larger and rear quarter windows that are 40% larger. Visibility is further augmented by the dual camera rearVIEW system. For upward visibility, the skylight is 40% larger and installed directly on a ¾ in (20 mm) forward sloping roof plate to easily shed debris. The operator can easily access the outside of the front window area for cleaning.
Simplified joysticks with programmable buttons allow the operator to customize controls for the clamp and accumulator arms, saw, differential locks, and drive functions. The roof-mounted A/C system, common with the 600H series skidders, improves cooling performance and comfort.
Another major change for the H-series feller bunchers is a new hydraulic system option. Loggers will now have the choice of the tried-and-true gear pump system, or the new piston pump load sense system for improved multifunctioning. Both system choices maintain the use of pilot operated joysticks for boom and steer control. New in-tank hydraulic filtration extends service intervals up to 2,000 hours.
Maintenance and service improvements include a larger engine air filter, a more conveniently located manual fuel fill port, an optional ground level fueling system and improved access to the hydraulic pumps and electrical systems. Source
Agility and hauling are enhanced for the company’s largest wheeled forestry harvester.
Komatsu is launching a new model of its largest harvester, the 951XC-1 harvester. It is purpose-built for enhanced stability, performance and productivity to the most demanding forestry operations. The Komatsu 951XC-1 is one of the largest harvesters on the market. Its eight driven wheels deliver good traction, manoeuvrability and stability, especially in steep, soft or rugged conditions. Inside the cab, operators experience automotive-level quality with refined controls and features built for all-day comfort and precision.
Key performance highlights:
- Eight-wheel drive ensures excellent stability and low ground pressure.
- Tractive force of 54,400 lbf (242 kN) supports operation in tough terrain.
- Komatsu’s 3PS hydraulic coordination system allows multiple head and crane functions to operate at full power simultaneously.
- Shortened crane centre-to-front-wheel distance enables wider working range and stronger reach.
- Cab includes an automatic 4-way levelling system, spacious layout, climate controls and high-visibility design to reduce operator fatigue
Designed for reliability and control, the 951XC-1 gives operators the confidence to perform efficiently in sloped, rough or soft terrain while maintaining Komatsu’s signature quality and productivity. What is special about the 951XC-1 is that it combines the strength of a 951-1 with an extremely compact design. Since it has about the same dimensions as the 931XC-3 it can be used in denser stands.

It is strong, it is stable, and it has eight wheels.
The Eco Log 688 takes the step into the next generation and joins the pendulum arm harvesters in the G series. The new 688G also comes with several other improvements. With a new hydraulic system, new pumps and naturally equipped with Eco Log´s modern harvester cabin, the 688G now offers an even higher tractive force and strength than before – in the machine as well as in the already strong harvester crane that has now been lifted to yet another level.
In the development of our 688G Eco Log have introduced a lot of new technology – an updated transmission, a new hydraulic system and a new generation of pumps. These are large updates that generate both high tractive force and performance to the machine. Thanks to a new crane valve and an electrically controlled crane pump, Eco Log get more power to the crane that can work efficiently even on full reach. As a customer, you get a really strong all-round machine in the same class as the largest machines on the market, a machine that can be used for everything from bigger thinning.
To achieve maximum traction force, the transmission and powertrain have been developed by equipping the machines with a completely new transmission pump and motor. Depending on the conditions in the forest and what the operator prefers, you can choose between different selectable driving modes where there is also a boost function for the situations when you need that extra power.
New on the eight-wheeled harvesters is also variable pressure levels, which means that the pressures to crane and harvester head is automatically calibrated and adjusted. It means that the machine is working with different pressure levels depending on the situation and external conditions. One gets plenty of power in both machine and crane when needed but can also operate with significantly lower pressure and save fuel when possible. Since the pump pressure calibration is automatic, it also makes servicing easier, and you never have to control the pressure on the crane or harvester head pumps. The machine takes care of that.
Other improvements that have been made on the machine are, amongst others, better tilt angles on the crane base and a stronger oscillation frame lock that adapts automatically to both speed and crane position. Also, the machine’s design has been given a boost. Source
The upgraded interior puts control at your fingertips
Caterpillar introduces a smarter articulated truck design with built-in automatic features for the next generation Cat® 725, 730, 730 EJ and 735 models. The upgraded interior puts control at your fingertips, with all functions accessible through a sleek touchscreen or a smooth, responsive keypad—plus, the touchscreen can be effortlessly navigated using the integrated jog dial for added convenience. New push-to-start with operator ID stores up to 50 operator IDs to quickly get to work and safeguard against unauthorized use.
Caterpillar’s latest machine design makes operating our next gen articulated trucks feel more comfortable, responsive, and user-friendly than ever. With the introduction of the Cat C13B engine on the 725, the improved power-to-weight ratio means it is up to 14% more efficient on our Tier 4 Final [and equivalent] machines1
The new Cat C13 engine powers the next generation of trucks with ratings from 257 to 316 kW (345 to 424 hp), depending on the model. Designed to meet global emission standards—including U.S. EPA Tier 4 Final, EU Stage V, Japan 2014, and Korea Stage V—the C13 features a compact, lightweight design with no need for exhaust gas recirculation. The machine is available in configurations suitable for all regions worldwide, ensuring reliable performance across a wide range of applications.
Requiring no operator input, advanced automatic traction control prevents wheel slippage in poor underfoot conditions for maximum traction and productivity. The new engine overspeed control works seamlessly with Automatic Retarder Control (ARC) to manage braking and automatically adjust engine speed—enhancing truck handling, improving steering response, and building confidence for newer operators in challenging conditions. Machine speed limiting supports safe operation by allowing ground speed to be set by the operator or in service mode—ideal for uneven terrain, high-traffic areas, or sites with strict speed regulations. Additionally, the integrated body height limiter promotes safety by helping ensure the machine operates within jobsite standards and height restrictions.
Caterpillar’s unique feature, Dynamic Roll Protection, supports rollover prevention, working in parallel with the field-proven Stability Assist, which prevents hoisting on uneven terrain. Configurable to material and jobsite conditions, this new feature monitors conditions to detect when the truck is experiencing high lateral acceleration, provides a visual and audible alarm, reduces fuel and applies service brakes automatically. It reduces the risk of machine rollover due to high-speed cornering, helping minimize downtime and safety repairs from rolling the truck. Additionally, Stability Assist software reports information via VisionLink® to increase awareness of when an event has occurred.
Reducing operator fatigue, the new Auto Wait Brake (AWB) automatically applies service brakes when the shift lever is in any position other than park and ground speed reaches 0 kmph. The service brakes apply in less than one second after the machine has stopped, and, after eight seconds, the transmission shifts to neutral with AWB engaging. Simply applying the throttle re-engages the transmission and releases the service brakes. This new feature eliminates the need to shift to park for short duration stops and saves fuel when shifting to neutral. This feature also works with the machine Hill Assist, by applying the service brakes, preventing rollback.
Providing front and rear proximity detection, all next generation articulated trucks offer an optional object detect and multiview camera via a separate secondary monitor. The system’s radar sensors, mounted fore and aft, provide visual and audible alerts when objects are within the truck’s travel path. Four discrete camera views, that are configurable to the operator's preference, are mounted at the front, rear and sides in order to enhance the operator’s view around the truck. Source
