Continuing the industry leading trend, the D3 Series also includes as standard, seat mounted adjustable joystick controls for operator comfort.
Maximum Performance
High performance power train provides maximum performance and production capability through the Electronic Torque Management system, standard two speed travel and an electronic hand/foot throttle with decel pedal capability.
Making Your Job Easier
Cat® “Intelligent Leveling” system provides industry leading technology, integration, and available features such as dual direction self level, work tool return to dig, and work tool positioner.
A Smooth Ride
A standard, fully independent torsion axle suspension combined with the optional Speed Sensitive Ride Control system improves operation on rough terrain, enabling better load retention, increased productivity and greater operator comfort.
Optimized Machine Capability
Maximize machine capability and control with the available Advanced Display, providing on-screen adjustments for implement response, hystat response and creep control. Also features multi-language functionality with customizable layouts, security system and rearview camera.
Sustainability
- The Cat® C3.3B engine meets U.S. EPA Tier 4 Final and EU Stage V emission standards.
- Cat diesel engines are required to use ULSD (ultra-low sulfur diesel fuel with 15 ppm of sulfur or less) or ULSD blended with the following lower-carbon intensity fuels up to: 7% biodiesel FAME (fatty acid methyl ester). Refer to guidelines for successful application. Please consult your Cat dealer or “Caterpillar Machine Fluids Recommendations” (SEBU6250) for details.
- Cat® Extended Life Coolant and long-life HYDO Advanced hydraulic fluids not only reduce downtime but help decrease the amount of fluid and filters that are replaced over the life of the machine.
- Boost productivity with Cat technologies like work tool positioner, return to dig, and Cat Smart Attachments.
- Save fuel and reduce your greenhouse gas emissions with efficiency features such as foot throttle pedal and cooling system demand fan.
