Every dozer fleet relies on robust and versatile workhorses, machines that consistently deliver day after day and year after year. This dozer is purpose-built to fulfill that crucial role. With a Tier 4 Final engine and an electronically controlled hydrostatic transmission, it achieves remarkably low fuel consumption without compromising on power. The standard parallel link undercarriage system includes rotary bushings designed to prolong wear life and reduce repair and maintenance costs. Alongside economy and power modes, a high engine RPM H mode enables operators to maintain ground speed even when handling heavy loads.
- Facilitate swift training for new operators
- Transition from mass excavation to finished grading at an accelerated pace
- Seamlessly integrate 3D design data into your machines
- Empower operators for efficient work pass after pass
Product Features and benefits:
Continuous Learning Capability
The dozer learns as it works with proactive dozing control, allowing even less experienced operators to automatically cut or strip from existing terrain. The dozer measures the terrain it moves over and uses that data to plan the next pass, potentially improving productivity by up to 60% compared to the previous generation.
Automated Fill Spreading
Lift layer control enables operators to spread fill from existing terrain with the press of a button. The dozer measures the terrain it tracks over, using the data to plan the next pass. This can lead to achieving up to double the production and consistent layers for compaction quality.
Efficient Material Leveling
Tilt steering control automatically tilts the blade to maintain straight travel during rough dozing, reducing operator steering input by up to 80%.
Quick Surface Creation
Operators can create a temporary design surface with the press of a button. Combined with other IMC 2.0 functions, the crew can begin stripping or spreading using automated input while waiting for the finish grade model.
Bridging Operator Skill Gap
Machine logic allows the dozer to continuously learn the terrain and make calculated decisions for the next pass. Intelligent Machine Control helps narrow the skill gap between new and experienced operators.
Advanced Machine Control Options
In select situations like auto stripping, rough dozing, spreading, and advanced finish grading, operators can choose nearly 100% machine control auto usage, even without a 3D model.
Adaptable Machine Learning
Automatic functions give the dozer the ability to learn from the operator’s blade input, resulting in increased adaptability, easier operation, and less reliance on operator input.
Precision in Finish Grading
To deliver unparalleled grading performance, IMC enables the dozer to look ahead at grade transitions and alter the blade angle accordingly.
