Your production partner

The XT445L-5 is our all-purpose tracked feller buncher. With its heavy-duty four-way leveling system, it is able to tackle the most rugged sloped terrain. This machine delivers high productivity with performance features such as an advanced cab and easy serviceability with smart design qualities.

  • Significantly greater lift capacity at full reach*
  • 10% more horsepower/16% more torque/5% lower fuel consumption*
  • Maximized uptime with optimized serviceability + Komtrax + Komatsu Care

Features and benefits

Outstanding serviceability

Gull-wing engine hood folds down for easy access to all engine service points, and doubles as an elevated work platform. Four additional swing-out doors open wide to provide easy servicing of all key components. All major service points can be easily and quickly accessed.

Exceptional maneuverability and multifunctioning

Easily work through dense forests with a short-tail swing. Cut close to the tracks with the proven set-back boom design. Powerful swing torque for demanding applications. Closed-loop track drive with dedicated pumps allows simultaneous operation of travel, swing, boom and tools for increased productivity.

Increased lift capacity

Due to refined boom and arm geometry, significantly greater lift capacity is achieved at full reach vs. previous models. Plus, this machine has excellent balance between boom lift and arm holding capacity. Can be equipped with a wide selection of Quadco high-speed disc saws.

Engineered modern forestry cab

Excellent comfort and visibility for total operator capability all day long. Positioned on the left side with superior visibility, especially of the tracks. Sloped roofline adds headroom for the operator. High-capacity automatic air conditioner, heater and defroster. Premium optional seat is ergonomic and heated/cooled.

Customizable operator controls

Advanced IQAN-MD4 digital control system enables customized control patterns and rates for up to three different operators. Helps to ensure precision and maximize multioperator productivity.

Rugged undercarriage

Using Komatsu engineering expertise, the tough and robust undercarriage provides significantly longer service life and day-to-day reliability.

Powerful, fuel-efficient engine

Get more done with the powerful and efficient Cummins QSL9 engine. 10% more horsepower; 16% more torque; up to 5% lower fuel consumption compared to XT-3 models. EPA Tier 4 final emissions certified.

Hydraulic protection

Robust forestry-specific guarding system covers the boom/arm/rear hydraulic tubes and hoses to help protect them from productivity-robbing operational hazards and debris.

Four-way leveling system

Heavy-duty four-way cab leveling system provides simultaneous front/rear/side leveling to ensure operator performance and safety on sloped terrain.

Reduced hydraulic oil needs

Innovative new hydraulic tank system design requires 55% less hydraulic oil compared to the XT-3 models which lowers your maintenance costs.

Standard Komtrax

Easily monitor vehicle usage insights that can boost productivity and aid in controlling cost with our standard telematics system. Monitors and records data such as location, operation map and fuel consumption. Notifies you when maintenance is due and helps keep your machine running at peak performance.

Komatsu Care

Every new Komatsu XT-5 is covered by our Komatsu Care maintenance program, so you can keep your machine producing at its best. For the first three years or 2,000 hours (whichever occurs first) we take care of most regular service, inspection, filter and fluid replacement, and labor – at your location, and using only genuine Komatsu fluids and filters.
