The purpose-built Komatsu XT-3 machines carry a lineage of superior maneuverability, multi-function capability and high-production in demanding forest environments. Models include the XT430-3 (non-leveling), XT430L-3, XT445L-3 and the larger new XT460L-3 ranging in operating weight from 61,300 lbs. (27,805 kg) to 72,000 lbs. (32,659 kg), and each model features a powerful 300 peak HP (224kW) Cummins 8.3 liter engine and 58,400 lb-ft (79.1k/Nm) of swing torque.

With a focus on improved operator productivity, Komatsu designed the XT-3 to have an all-new cab. Changes include a sloped roofline that increases headroom above and forward of the seat, and reduces debris buildup. A 10 percent larger floor-to-ceiling front window, larger side windows with up to 90 percent greater viewing depth, and a 60 percent larger skylight window provide a widescreen field of view. For night operation, 11 brilliant white LED lights deliver two to three times more illumination in all directions.

The XT-3 cab design is more spacious and quieter. It is pressurized with fresh, filtered air for the new automatic heating, cooling and defrosting system. The ergonomic seat and easy-to-reach instrumentation add convenience, and provides easier access to new integrated storage areas including a cooler lunch box and thermos bottle. All comparisons and performance claims are made to previous Komatsu XT-2 models.


The Komatsu Forestry XT-3 Series features the IQAN-MD4 programmable digital control system.

The XT-3 Series features the new IQAN-MD4 programmable digital control system which is one of the most advanced systems on the market. All former analog gauges and warning lights are now prominently displayed on the highly visible and durable 7-in. (18 cm) LED color touchscreen monitor.

The system accommodates individual preference settings for multiple operators, records harvest data and provides advanced diagnostic reports. Highly intuitive Komatsu programming makes the system very easy to use.

The Komatsu XT-3 series machines include the latest Komatsu undercarriage and hydraulic improvements for greater reliability and durability.

The undercarriage has additional bottom rollers that improve track chain support and load distribution. The upgraded chain guide (rock guard) material extends service life and track chain alignment has been optimized by using a continuous straight-line chain guide profile and lengthened chain guide profiles at the idlers and sprockets. On the XT445L and 460L models the track roller guards are removable for easier access.

On the hydraulic system front, Komatsu upgraded the implement pump bearings on all models to provide longer service life. On the XT460L-3 model lift capacity at full reach increased by 37 percent.

The X-3 series can be equipped to meet a wide range of customer applications. There are up to nine hydraulic system arrangement, two heavy duty boom and four heavy duty arm options that accept a broad range of disc saw, bar saw and processing head cutting attachments. Komatsu’s advanced parallel boom geometry allows fast boom movement and smooth control which increases operator productivity and reduces fatigue.

Three swing-out service doors, featuring triple-hinged and positive dove-tailed lever latch designs, provide easy service access to all service and maintenance points including all fluid fill points, filters, batteries, hydraulic pressure checkpoints, and hydraulic hoses and pumps. Easy access to grease fittings provides simple maintenance which helps extend bearing life.
