John Deere Adds SmartGrade to Two Excavators

SmartGrade grade control is now available on the John Deere 210G LC and 350G LC excavators, factory-installed and -calibrated.

“By incorporating precision technology, such as SmartGrade, on our excavator lineup, we are boosting job site productivity and efficiency while enhancing the capabilities of our operators,” said Justin Steger, solutions marketing manager, in a prepared statement. “However, there isn’t a one-size-fits-all solution, and contractors need options to pair the right technology with their business needs. This is where customers really benefit from the flexibility of our grade management path.”

Deere offers four grade-management options for its excavators: SmartGrade, SmartGrade-Ready with 2D, 3D Grade Guidance, and 2D Grade Guidance. Upgrade kits for each grade management option are also available. A SmartGrade excavator automates the boom and bucket functions for the operator to easily achieve a smooth and accurate finish grade. Using GNSS positioning technology for accurate horizontal and vertical positioning, the machine controls boom and bucket movements to a precise design target. This enables the operator to focus on controlling the arm function while the system raises and lowers the boom to maintain grade.

SmartGrade-Ready with 2D provides a 2D system with semiautomated functions, improving the ease of use without the need for GNSS technology or 3D design plans. Additionally, the SmartGrade-Ready machines arrive from the factory prewired for the SmartGrade system, enabling the owner to upgrade in the future, if desired. The 3D or 2D Grade Guidance options provide reference information to the operator in the cab to improve productivity. The 2D Grade Guidance option shares bucket tooth and cutting-edge elevation information relative to a benchmark with the operator through the in-cab monitor. The 3D Grade Guidance option accurately provides the horizontal and vertical bucket position using GNSS technology and can make use of a 3D design plan. All guidance and control options are available with an optional laser receiver, which leverages an ultra-precise local external elevation reference.

With SmartGrade or SmartGrade-Ready machines, the selectable bucket control feature automatically maintains the user-defined bucket angle throughout grading passes. This feature helps the operator place material more effectively, reducing waste and saving money. Factory joystick integration provides the ability to adjust the grade offset, set a benchmark on the 2D system, measure a desired point on the bucket with the 3D system or easily turn on and off automatics and protect features, helping further boost productivity by keeping the operator’s hands on the joystick and in control.

New precision technology features include Virtual Front, which hydraulically limits and automatically stops the bucket cutting edge from contacting the front of the machine at a selectable distance, preventing machine damage. The over-dig protect feature limits the bucket’s cutting edge from going below the target design surface, preventing costly over digging on the job. Additional virtual fence technology features, such as Virtual Ceiling, Virtual Floor, Virtual Swing and Virtual Wall, provide the operator with audible alerts as the machine approaches an adjustable setpoint, allowing operators to focus on the task at hand.
