Features and benefits

Tracked Harvester_XT430 5_Canada_SR_220412_03.jpg

Helps reduce servicing downtime

The faster you can service your machines, the faster they can get back to work. Komatsu’s engine gull-wing and wide swing-out doors offer quick and easy access to all engine service points and all key components.

Equipped to multi-task

Closed-loop system allows operators to simultaneously travel, cut, delimb, harvest and swing timber — all in one powerful and agile machine. Engineered with hydraulic lines for each function, driving performance while helping to prevent machine damage.

Maneuvers in dense terrain

Work better through dense forests and clear-cutting environments with a short-tail swing design. Cut close to the undercarriage and tracks with set-back boom engineering. Powerful swing torque for demanding applications.

Better lift capacity

Handling trees with the arm fully extended is even easier with a design that significantly increases lift capacity compared to previous models. Excellent balance between boom lift and arm holding capacity. Can be equipped with a wide selection of harvesting saw heads.

Designed for operator comfort

Help reduce fatigue and support productivity by giving your operators a roomy, comfortable work environment. Features include superior visibility - especially to the tracks - and provides powerful heating, cooling and defrosting systems.

Customizable for each operator

When working shifts switch, the controls can be swapped by adjusting to each operator’s preference (up to three setting) to help maximize productivity. Set preferences for joystick, boom, stick, tool tilt, swing, cab leveling and more.

Adapts to long or short reach

Adapt your equipment to the job with two different working ranges. Use the short reach and larger-scaled head when the job demands it. Switch to a longer reach and more compact designed head when working in restricted spaces.

Powerful and fuel-efficient

Get more done with the powerful and efficient Cummins QSL9 engine that delivers more horsepower and torque while using less fuel consumption compared to XT-3 models. EPA Tier 4 final emissions certified.

Stands up to debris

Forestry conditions pose debris hazards that can slow operations and reduce productivity. Komatsu’s harvesters help minimize that risk with various design specific forestry guarding.

Promoting stability on slopes

Operators can work with confidence even on sloped terrains. A heavy-duty, four-way leveling system promotes front/rear/side leveling for exceptional stability. The fuel tank placement lowers the center gravity to offer even more enhanced stability.

Designed to meet your job demands

Forestry harvesting demands vary widely, so Komatsu tracked harvesters are designed to adapt. You can factory-equip your machine with a broad selection of harvesting saw heads — to match the type of performance your job sites require.

Promote lower maintenance costs

Save on maintenance costs with an innovative hydraulic tank system design that requires 55% less hydraulic oil compared to the XT-3 models. Plus, pumps are equipped with hydro-nucleation to help prevent pump cavitation and are 17% larger* to help extend component life by operating 500 rpms slower. *17% larger than the XT-3.
