D7EFeatures
ElectricDrivePowertrain
The revolutionary electric drive system delivers
excellent dozing efi ciency and performance while
consuming considerably less fuel and fewer parts
to reduce lifetime owning and operating costs.
OperatorStation
Center post cab design offers more space,
all-around visibility and reduced noise levels.
ACERT™EngineTechnology
Cat C9.3 engine with ACERT™ Technology powers
an electric generator that efi ciently converts
mechanical energy into AC electrical current.
The engine is integrated with a Cat aftertreatment
solution to meet U.S. EPA Tier 4 Interim/
EU Stage IIIB emissions standards.
GradeControlReady
Deeply integrated wiring is installed at the factory
to make it simple to add a Cat AccuGrade™
system for improved accuracy and increased
productivity.
Serviceability
Tilt cab provides easy access to drive system
components, hydraulic pumps and lines.
Grouped service points and large access
doors facilitate easy daily maintenance.
Sustainability
Designed to do more work while consuming
fewer resources.
