Entry-Level Machine Control with Topcon MC Mobile - The FourCast Ep.3
FourCast Spotlight: Entry-Level Machine Control with Topcon MC Mobile
In this episode of the FourCast, Derek from Foursight Solutions breaks down a powerful, accessible solution for contractors looking to step into machine control: the Topcon MC Mobile system.
A Smarter Way to Grade
Designed for compact machines, the MC Mobile system uses a network of sensors mounted on the bucket, stick, boom, and machine body to continuously calculate cut and fill based on a 3D project model. Inside the cab, a 7-inch display gives operators real-time guidance—helping them dig to precise grade without relying on stakes, lasers, or ground crews.
The goal? Get to grade faster, safer, and with fewer people on site.
Built for Owner-Operators
One of the biggest advantages of the MC Mobile system is its simplicity and affordability. It’s an all-in-one solution—complete with a base station, rover, and tablet—that allows operators to:
- Set up the job site
- Load and view 3D designs
- Control grading directly from the machine
With a lower price point, it’s an ideal entry into grade control for contractors who want the benefits of precision without investing in full-scale systems.
Real-Time Accuracy, Real-World Efficiency
Whether shaping a pond or fine-tuning finish grade, the system provides constant feedback as operators move the bucket. The goal is simple: get the cut/fill number as close to zero as possible.
Key capabilities include:
- Survey-grade GPS accuracy (±0.05' to ±0.08')
- Optional total station accuracy within hundredths of a foot
- Adjustable vertical offsets for subgrade or finish grade work
- Automatic model rotation that matches machine orientation
Flexible, Versatile, and Fast to Install
The MC Mobile system can be installed on nearly any machine—old or new, compact or full-size—making it highly versatile across fleets. Installation typically takes about a day, with Foursight providing hands-on training to ensure operators are ready to go almost immediately.
Beyond the Machine: Full Jobsite Visibility
Paired with Topcon’s Hyper VR GPS system and Pocket3D software, users can:
- Stake out utilities, property lines, and design features
- Navigate job sites with precision
- Prevent costly mistakes like hitting buried infrastructure
A Practical First Step into Machine Control
For contractors curious about grade control but hesitant to commit to larger, more complex systems, MC Mobile offers a practical, user-friendly starting point. As Derek explains, it’s about making the technology accessible—without sacrificing performance.
