Hitachi developed its integrated excavator grade-indication system, Hitachi Grade Guidance, with Topcon to help operators cut to final grade faster using real-time display of distance to grade.
The 2D Grade Guidance option displays the elevation of the cutting edge in relation to a laser reference plane. 3D Grade Guidance uses the Global Navigation Satellite System (GNSS) to locate the cutting edge's position and elevation.
The new option is now available on the Hitachi ZX210-6, ZX210LC-6 and ZX350LC-6 excavators, and will be offered on additional Dash-6 models in the future.
Grade Guidance’s real-time display of distance to grade allows for grade management without leaving the cab, and reduces the need for a grade checker or grade stakes.
Grade Guidance is supported by Hitachi’s dealer network, and it is installed and calibrated at the factory, so it arrives on jobsites ready to work. Its integration into the machine’s cab and structures helps shield key components such as wire harnesses and sensors from damage, and while also providing fingertip control with switches placed in joysticks.
Customers can choose 2D Grade Guidance or 3D Grade Guidance. The 2D Grade Guidance with an optional laser receiver displays the elevation of the cutting edge in relation to a reference 
A Grade Guidance-ready option that includes sensor mounting
brackets is also available to simplify installation of a Trimble, Topcon or Leica aftermarket grade kit.
In addition to the new factory-integrated Grade Guidance, Hitachi offers an open architecture option that includes sensor mounting brackets to enable installation of a Trimble, Topcon or Leica aftermarket kit.
