What Is AccuGrade? Understanding Machine Control Ready Earthmoving Equipment

AccuGrade is a type of integrated 2D machine control system from Caterpillar that uses an Advanced Tracking System (ATS) to accurately determine and monitor blade position and grading. This solution is unique in that it was the first product of its kind to integrate a machine’s electro-hydraulic system with sensor-free, automatic grading capabilities.

 AccuGrade is one piece of how the construction industry has evolved over the last couple of decades, shifting from a field that required hours of labor and highly skilled operators to complete projects to one that relies on the most advanced technology available to boost productivity and fill in gaps caused by skilled labor shortages. 

Contractors today are becoming increasingly aware of the benefits of machine control systems and are adopting technology that enables a smoother, more efficient operation. With options like Cat AccuGrade and other 2D machine control systems that allow for third-party GPS integration, operators have several options for upgrading their fleet or automating their current machinery.

The Evolution of Construction Grading and 2D Control 

While heavy equipment operators may have once performed most of their grading “by hand,” machine control has altered the way operators work. Twenty years ago, operators would achieve grade by “watching and feeling the sacred bubble.” This method required meticulous human monitoring and calculation to accurately adjust the hydraulic operation to reach the desired grade slope. It would be up to operators to manually adjust the slope, rotation, and mainfall of their machines, a process that would involve hours of work, inevitable errors, and costly rework. 

The introduction of 2D machine control systems to the earthmoving field revolutionized the way operators maintain and achieve the desired slope. These advanced systems utilize lasers or sensors to maintain blade position in relation to the machine and often provide elevation reference or meet depth and slope targets. This technology works quickly and precisely, enabling crews to achieve grade in a fraction of the time it took before and to get it right the first time around. Additionally, 2D machine control systems benefit contractors of every skill level, helping the most skilled operators perform even more quickly and accurately than before while lowering the learning curve for newer operators. 

What Is Machine Control Ready?

Essentially, the terms “machine control ready” and “AccuGrade” mean the same thing. They’re also similar to commonly used terms such as SmartGrade Ready, Grade Control Ready, and Attachment Ready Options (ARO). Machine control technology relies on access to and control of a machine’s hydraulic system to manipulate its cutting-edge position. Before machine control-ready options were available, operators would need to pay to add a hydraulic valve to heavy equipment to control the raise and lower – an investment which could cost well over $10,000. 

As machine control has become integral to how many operators do earthwork, heavy equipment manufacturers have started building machinery that includes a hydraulic system that can be connected to the machine’s CAN or hydraulic interface with specialized cables. This system can be easily accessed and controlled by machine control providers, making it more feasible and affordable to install a machine control system.

While CAT was the first manufacturer to develop equipment with an “AccuGrade feature” many other companies have come out with their own variations of machine control ready dozers, graders, and excavators. This includes John Deere’s SmartGrade and Komatsu’s Intelligent Machine Control. 

These manufacturers may install brand-specific mounting hardware, cabling, or sensors on the machine at the factory. This brand-specific equipment can be useful and save time and money if it is the correct technology brand for your company – but it can also waste time and money if it is not the correct technology. No matter the brand of heavy equipment, the primary benefit of machine control ready machines is hydraulic system access. 

Upgrading to 3D Machine Control Systems 

The progression from grading by hand to utilizing 2D machine control systems made a significant impact for contractors; however, modern systems go a step further by utilizing 3D models and GNSS base and rover systems. 3D machine control systems utilize GNSS technology or a robotic total station to provide operators with real-time positioning data and surveying capabilities, including grade checking, and stake placing. They can also position equipment horizontally and take in-field volumetric calculations. 

3D machine control systems are the ideal choice for large projects or operators working in complex landscapes. For companies that currently utilize 2D machine control, these systems are scalable and stackable. Meaning you can continue utilizing your current technology while adding on equipment and systems that enable 3D machine control. 

How To Get Started With Machine Control Systems

There are many factors you need to consider to get started using machine control systems. 

Inspect Your Equipment 

First off, you need to consider your heavy equipment. If you’ll be upgrading your current fleet to use 2D or 3D grade control, you’ll want to know if your heavy equipment is machine control ready or if needs to have a hydraulic valve installed. If you’re planning to purchase new equipment, take into consideration if it is already prepped for a machine control system and if brand-specific equipment is the best use of time and money for your company. 

Choose Your Machine Control System 

You’ll also need to consider whether you want to invest in a 2D or 3D machine control system. This is highly dependent on the size of your operation, your budget, and the features you’re looking for. 3D systems can have the highest benefit on ROI as they drastically improve performance, speed, and accuracy. However, 3D machine control comes with a higher initial investment as you’ll need to consider the price of the system itself in addition to the costs associated with installation, creating Digital Terrain Models, and purchasing a total station or GNSS rover. 

Partner With a Qualified Machine Control Provider
