The dozers 23 feature two selectable Working Modes, Economy (E) and Power (P), that match machine performance to the application. E Mode is intended for all general dozing, leveling and spreading applications providing adequate speed and power while saving fuel. P Mode is intended for slot dozing, ripping, uphill dozing or other applications that require maximum power. The crawler dozers are equipped with KOMTRAX technology, allowing for remote diagnosis by the distributor.

The Komatsu Diesel Oxidation Catalyst (KDOC) has an integrated design that does not interfere with daily operation.  The system removes soot using 100 percent “passive regeneration” without the need for a Diesel Particulate Filter (DPF).
