ADEM™ A4 Engine Controller. The air-
cooled ADEM A4 controller is the brain
of the engine and contains the engine’s
control software. It regulates fuel
delivery, airflow and other engine
functions. In addition, it directs the
HEUI injectors to deliver multiple
injections of fuel during the engine’s
compression stroke.
Fuel Delivery. Multiple injection fuel
delivery involves a high degree of
precision. Precisely controlling the
combustion cycle lowers combustion
chamber temperatures, which lowers
emissions and optimizes fuel economy.
This translates into more work output

Work Tools
The D6R Series III Work Tools are designed to provide flexibility to match the machine
to the job.

Variable Pitch Angle Tilt (VPAT) Blade.

The Variable Pitch Angle Tilt (VPAT)
blade allows the operator to hydraulically
adjust the blade lift, angle and tilt
simultaneously using the ergonomically
designed blade control. The operator
can also manually adjust blade pitch.
The versatility of the VPAT blade gives
the D6R III the ability to take on a
variety of applications such as finish
grading, spreading material, side
casting, V-ditching and backfilling.
The VPAT blade is available on the
XL, XW and LGP configurations and
requires either a counterweight or a
rear work tool attachment for optimal
machine balance.
The new D6R III VPAT blade offers
several improvements over the
Series II design:
• Manually adjustable blade pitch
• Better cutting edge visibility from
