New Komatsu XH951XC-1 is Built to Rule the Forest

In the dynamic world of forestry, where terrain is rugged and productivity is king, professionals need machines that are more than tough — they need to be smart, stable and operator-focused. That describes the updated 951XC-1 wheeled harvester Komatsu has brought to the North American market, a machine tailored to the demands of final logging. With an eight-wheel drive system, an intuitive operator environment and exceptional hydraulic power, this harvester is designed to tackle the most challenging logging assignments efficiently, comfortably and with precision. It’s also Komatsu’s largest forestry machine.

Let’s explore standout features that make the 951XC-1 a powerful ally in modern forestry.

Benchmark stability with eight-wheel traction

Forestry professionals know that challenging terrain is par for the course. That’s why the Komatsu 951XC-1 is equipped with eight powered wheels and dual suspension systems, providing outstanding traction and stability on steep slopes and uneven ground. The combination of eight wheels, and a swing axle/bogie suspension ensures the harvester’s weight is distributed more evenly, promoting a more stable lower center of gravity and more continuous ground contact.

This not only improves climbing ability and maneuverability but also reduces ground pressure, a vital factor when operating on sensitive or wet forest floors.

 A cab built for endurance

Long hours in the woods require a workspace that keeps operators alert and comfortable. The Komatsu 951XC-1 delivers with a spacious, rotating cab offering 360° visibility, intuitive control placement and a self-leveling system that keeps both the cab and crane level in sloped terrain.

The seat is air-suspended, heated, cooled and highly adjustable for lumbar and posture support. Climate control systems include high-capacity HVAC, helping operators stay focused in extreme temperatures. There is also a heated/cooled food box and a second beverage cooler — small touches that make a big difference on 12-hour shifts.

Smart hydraulic system for multitasking power

The heart of any harvester is its hydraulic system and Komatsu’s three-pump version is designed for multitasking without compromise. This dual-circuit setup allows operators to slew the crane, feed the log and reposition the machine simultaneously without losing flow or pressure.

With a flow rate of 139 GPM and system pressure up to 4061 PSI, the 951XC-1 delivers smooth, responsive performance under heavy workloads. Whether you're processing hardwood or clearing final cuts, it delivers the hydraulic strength needed to operate large heads and fast feed rollers with precision.

Engineered for power and efficiency

The 951XC-1’s 287 HP engine doesn’t just offer raw muscle; it’s tuned for the unique demands of forestry. Delivering up to 944 lb-ft of torque at low RPM, it provides consistent power while keeping fuel consumption in check. This Tier 4 Final and EU Stage V-compliant engine also features:

• EGR-free design for better fuel economy
• 123-gallon fuel tank and 11-gallon AdBlue tank for long operational windows
• Easy-to-access filters and grouped service points for reduced downtime

Enhanced crane control with smart features

The optional Smart Crane system on the 951XC-1 simplifies repetitive crane operations. With one joystick motion, the operator can return the crane from full reach to full retract — ideal for felling and processing in tight windows.

Precision and responsiveness are key advantages. Operators can easily position the harvesting head exactly where they need it, reducing cycle times and operator fatigue. It’s a game-changer for productivity.

Harvester heads built for every task

From crooked hardwoods to high-volume final felling jobs, Komatsu’s wide selection of harvester heads ensures there’s a perfect match for every assignment. The 951XC-1 supports multiple C and S class heads, including:

• Komatsu C144 and C164: Known for their high feed force and fuel-efficient roller feed systems
• Komatsu S132 and S172: Ideal for durability in rough weather, with debarking capability on select models

  Operators can also benefit from advanced head technologies such as:

• Constant Cut: maintains optimal chain speed for smooth, precise cutting
• Flex Friction Control: reduces feed resistance on crooked stems
• Find End Option: accurate log measurement even when processing pre-felled timber

Customization and operator-focused technology

Recognizing that the cab is an operator’s office, Komatsu offers significant customization options. From mini steering wheels to joystick layout personalization, touchscreen computers to rearview cameras, the 951XC-1 allows each crew to set up the machine to match their workflow.

Other optional features include:

• Smart Crane/Smart Flow
• Extra LED working lights
• Komatsu MediaZone for audio entertainment
• Reinforced hood guards
• Multiple tire and tread configurations for varied terrain
  

And when it’s time for maintenance, operators will appreciate ground-level daily inspection points, automatic lubrication and onboard diagnostics via the MaxiXT control system.
