Dozers-Crawlers - D39EX-22

Download Specifications

Overview

​Komatsu's D39EX-22  dozer has the new 'unique' slant nose design which delivers industry leading visibility to the blade thanks to a short forward-sloping bonnet. This means improved machine control which results in increased efficiency and productivity.

The slant nose design achieved by mounting the cooling package at the rear of the machine, gives the dozer operator a clearer view of the blade and work area.

Typical applications for the D39EX-22 dozer, include subdivision, golf courses, reclamation projects and mine site maintenance.
