Super-slant nose
The standard D39EX-22 and low ground pressure D39PX-22 crawler dozers are equipped with Komatsu’s proven Hydrostatic Transmission (HST). The D39EX-22 features a super-slant nose coupled with a new cab forward design that moves the operator closer to the blade while improving machine balance, ride and stability. The dozers range in operating weight from 20,834 to 21,804 pounds. Komatsu’s 4.5-litre SAA4D107E-1 engine has 105 net horsepower at 2,400 rpm.
The steering system provides smooth agile movement when dozing, even in gradual turns, permitting the operator to approach objects accurately in corner grading and sidewall operations. The D39-22 dozers employ a large, power angle-tilt blade with a capacity of 2.89 to 3.01 cubic yards, which results in more material staying on the blade.
