Choosing the Right Machine for 3D Grading
If you're using these machines for more than just lifting and loading, precision matters. That's where 3D guidance systems like those from FJDynamics come into play. For example, if you pair a large skid steer with the FJD G31 PRO 3D Excavator Guidance System, or use the FJD H36 PRO 3D Motor Grader Control System, you're upgrading from brute strength to surgical precision. These systems help eliminate over-digging, increase grading efficiency, and reduce operator fatigue. Need something lighter for smaller skid steers? FJD Easydig G31 Lite is a great choice.Use Cases: Where These Machines Excel
- Road construction: Larger skid steers can mill, grade, and prep.
- Demolition: High ROC and horsepower let you rip through tough materials.
- Site prep: With 3D control systems, you can hit grade on the first pass.
- Material handling: Pallets, debris, or fill — no problem.
