Trimble Expands Excavator Grade Control with Dual DA2

Trimble is expanding its Earthworks 3D excavator grade control portfolio with a lower-cost configuration featuring dual DA2 GNSS receivers, aimed at small and medium-sized construction contractors. Scheduled for availability in mid-Q4 2026, the system combines Trimble’s ProPoint positioning engine with a subscription-based commercial model designed to lower the upfront cost of adopting digital machine control.

The configuration is intended to make 3D grade control more accessible to contractors operating smaller equipment fleets. It also includes access to Trimble WorksManager for managing construction data between the office and the job site, connecting machine positioning with digital design workflows.

The launch adds another option to Trimble’s existing earthmoving technology portfolio, allowing contractors to evaluate 3D machine control without necessarily committing to higher-cost configurations.

Dual GNSS Receivers Support 3D Excavation

Trimble’s new configuration combines two DA2 GNSS receivers with its ProPoint positioning engine to provide three-dimensional positioning for excavator grade control. The system is designed to help operators understand the bucket’s position relative to the digital project design during excavation.

Applications can include trenching, foundation excavation, drainage installation and formation preparation. By providing positioning information in the cab, grade control systems can help operators work towards specified depths, slopes and excavation profiles without relying exclusively on physical setting-out and repeated survey checks.

More accurate excavation can reduce unnecessary material movement and corrective work. The potential benefits depend on the project design, operating conditions, machine configuration and the accuracy requirements of the task.

Trimble says its ProPoint technology is designed to maintain reliable GNSS positioning in challenging satellite reception environments. However, the announcement does not specify the new configuration’s machine-level accuracy figures, detailed receiver arrangement or the automatic control functions included. Contractors will need to confirm these specifications when evaluating the system for particular applications.

As with other GNSS-based machine control technologies, performance depends on satellite visibility, suitable correction services, machine calibration and the quality of the underlying digital design. Sites with significant obstructions may require additional planning to maintain reliable positioning.

Subscription Model Targets Smaller Contractors

The new configuration introduces a subscription-based route to adopting 3D excavator grade control. Instead of relying solely on a conventional upfront purchase model, contractors can access the system through a Trimble Works subscription that includes WorksManager.

This approach is intended to reduce the initial financial barrier for smaller businesses that may have limited budgets for advanced equipment technology. Contractors operating only a few excavators can face different investment considerations from major civil engineering companies, which may distribute technology costs across larger fleets and multiple projects.

The commercial benefits will depend on the full cost of ownership. Hardware, installation, GNSS correction services, operator training and ongoing support can all affect the financial case for adopting machine control. Trimble has not provided specific subscription prices or detailed hardware payment terms in the supplied announcement.

Equipment utilisation is another consideration. Contractors carrying out frequent excavation to defined levels may have more opportunities to benefit from digital grade control than operators whose machines primarily perform less design-intensive work.

A subscription model can also make software expenditure easier to plan as a recurring operating cost. Whether it reduces overall expenditure compared with other purchasing arrangements will depend on the contract terms, the length of use and the productivity improvements achieved.

WorksManager Connects Office and Field Workflows

The inclusion of Trimble WorksManager supports the transfer and management of construction information between office teams and connected equipment. This is an important part of digital machine control, as excavators need access to the correct design files to work against specified levels and geometry. Trimble is also expanding its digital construction capabilities through AI-powered risk intelligence for construction drawings, extending the use of technology to analyse project documentation.

On projects where designs or construction requirements change, teams must ensure that updated information reaches the relevant machines. Centralised data management can help organise project files and reduce dependence on manual transfers between office computers and equipment.

Introducing a digital grade control system also involves more than fitting receivers to an excavator. Contractors need suitable digital designs, correctly established site coordinates, reliable data management procedures and operators who understand the information presented in the cab.

For businesses already using digital surveying or machine control technology, integrating another machine into an established workflow may be more straightforward. Contractors adopting these systems for the first time may need to update their surveying, design preparation and site supervision processes.

Expanded Earthworks Options for Construction Fleets

The new configuration extends Trimble’s existing Earthworks platform rather than establishing a separate product family. Contractors familiar with the software can assess the dual DA2 receiver option alongside other machine control arrangements, subject to confirming compatibility and technical requirements.

Cameron Clark, senior director of earthmoving solutions at Trimble, said the company aimed to provide a competitive alternative without compromising the positioning performance expected from its machine control products.

The company’s announcement positions the configuration as an option for cost-sensitive contractors seeking to introduce 3D technology across their operations. Wider adoption could help more businesses incorporate digital positioning into excavation workflows, although the practical benefits will vary according to fleet size, project type and utilisation.

The configuration is scheduled to become available through Trimble’s dealer network in mid-Q4 2026. Contractors can check regional availability and purchasing information through the Trimble dealer locator.

By combining dual DA2 receivers, ProPoint positioning and WorksManager access, Trimble is expanding the range of options available to contractors considering digital excavator control. Final pricing, installation requirements and detailed technical specifications will be important factors as businesses assess whether the configuration meets their operational needs.
