This dozer stands as a reliable workhorse in any fleet—versatile and powerful, ready for the demands of daily use. Purpose-built from the ground up, it features a Tier 4 Final engine and an electronically controlled hydrostatic transmission, ensuring remarkably low fuel consumption without compromising power. The standard parallel link undercarriage system incorporates rotary bushings, extending wear life and reducing repair/maintenance costs. With economy and power modes, as well as a high engine rpm H mode, operators can maintain ground speed even under heavy loads.
- Quickly train new operators
- Accelerate from mass excavation to finished grading
- Seamlessly integrate 3D design data into your machines
- Empower operators for efficient performance, pass after pass
Product Features and benefits:
Continuous Learning in Action
With proactive dozing control, even operators with limited experience can effortlessly cut or strip from existing terrain. The dozer analyzes the tracked terrain, utilizing this data to plan the subsequent pass. This approach can enhance productivity by up to 60% compared to the previous generation.
Automatic Spread Control
The lift layer control empowers operators to automatically spread fill material with a simple button press. By measuring the tracked terrain and utilizing gathered data, the dozer ensures double production and consistent layers for superior compaction quality.
Effortless Material Leveling
Tilt steering control automatically tilts the blade, maintaining straight travel during rough dozing and reducing operator steering input by up to 80%.
Rapid Surface Creation
Operators can swiftly create a temporary design surface with the quick surface creation feature. This, combined with other IMC 2.0 functions, allows the crew to automate stripping or spreading while awaiting the finish grade model.
Closing the Skill Gap
Machine logic enables continuous learning of the terrain, making calculated decisions for the next pass. Intelligent Machine Control significantly reduces the skill gap between new and experienced operators.
Cutting-edge Machine Control
In specific scenarios—auto stripping, rough dozing, spreading, advanced finish grading—operators can opt for nearly 100% machine control auto usage. They can even apply automatic control without the need for a 3D model.
Adaptable Learning Machine
Automatic functions endow the dozer with the ability to learn from the operator’s blade input, resulting in increased adaptability, easier operation, and reduced reliance on operator input.
Exceptional Blade Response
To deliver unmatched grading performance, IMC enables the dozer to anticipate grade transitions and adjust the blade angle accordingly, ensuring outstanding blade response for finish grading.
