MARA integrated laser system + GPS
The MARA integrated system works simply, accurately and effectively as it involves the use of laser control as well as the positioning via GPS. The most striking difference between the levelling system with laser control and the system with GPS control is its accuracy: the laser system allows you to create a more precise plan (± 2 mm error), while the GPS system gives an error of about ± 10 mm, which changes every 12 minutes when you activate the new constellation of satellites that give the reference plan signal. This is why MARA opted to use the laser system to implement the plan, despite the control limit of a circle of about 1300 m. It then uses the GPS system to define the position of the grader on the ground. The system is then integrated by the laser, which controls the height of the grader, and by the GPS, which controls its position.
The processing time and the yield per hectare will depend on the condition of the ground before work:
- The volume of soil to be moved;
- The distance between the areas to be dug out and those to be filled in;
- The texture of the soil (clay, sand or medium texture);
- Soil water content.
These parameters define the time required to complete the levelling.
The system does not require the operator to do anything or have extensive experience; accordingly, even an inexperienced operator will be able to carry out the work perfectly and in the set time.

An explanatory example for carrying out a plan, after the calculation made by the MARA integrated system, on a plot of 1 hectare with:
- A difference of a 20 cm drop between the highest and lowest point;
- A maximum distance of 80 m between the areas to be dug and those to be filled;
- Medium-textured soil;
- With a relative humidity of about 45%;
- Using a 4 m wide grader;
- With a 120 HP tractor.
The work will be completed in about 6 hours.
Another example of a plan made on a plot of 1 hectare already levelled in advance, but to be corrected, with:
- A drop of about 2-3 cm;
- The same conditions as those in the previous example;
- The same grader;
- The same tractor.
The work will be completed in about 1.5 hours.
