When you need compact versatility

Designed to excel in underground utility and general construction in urban environments, this new Komatsu short tail swing excavator is at home in confined spaces. Extremely transportable, it delivers high attachment flow with in-cab programmable flow rates for a wide range of attachments.

Features may include:

Compact design

For working in tight areas, a compact short tail swing offers maneuverability in more confined areas than a conventional excavator, such as in a single lane of traffic. The conventional boom design has a greater raising angle to reduce the front bucket swing radius.

Fast cycles and custom modes

Faster boom up/swing speed, combined with responsive quick arm speed, makes excavating and leveling work easier and more efficient over previous models. Six working modes let you tailor the machine to the tasks required, whether it be for performance or fuel savings.

Versatility and efficiency come standard

Standard high flow auxiliary hydraulics with proportional joysticks allows you incredible job versatility while providing precise attachment control. Standard grading blade with new moldboard profile improves backfilling and light grading efficiency over previous models.
