Cat Grade with 2D
Standard on all Next Gen excavators. Provides real-time bucket depth and slope guidance on the in-cab display, eliminates manual grade checking and re-work.
Cat Grade with Advanced 2D
Adds automatic bucket floor control and fine-grading capability. Reduces operator fatigue and improves grade accuracy to ±25 mm without GPS infrastructure.
Cat Grade with 3D
Full GPS/GNSS machine control for automated bucket positioning to design surfaces. Works with any major site design software; no stakes, no string lines.
Smart Mode
Automatically matches engine speed and hydraulic flow to load conditions, delivering up to 45% fuel savings on the 320 vs. previous-generation excavators.
VisionLink® Telematics
Remote equipment monitoring via Cat's VisionLink platform, tracks location, fuel burn, operating hours, fault codes, and maintenance intervals in real time.
