GPS laser leveller for agricultural soil

Mara Laser is a business activity that for over 30 years has been examining, producing and trading laser and GPS controlled laser levellers, turning towards clients in about 30 nations everywhere in the world.
Thanks to GPS and laser control technologies, we can reach considerable results in many sectors of utility: from agricoltural ground to sport courts, from building constructions to road excavations, from landscaping to ground scraping.
Mara’s levellers ensure a series of returns and high capacity in various situations: from the machine operating speed regime, to a total trustworthiness and guarantee of the final success.

Mara’s technology

The technology used by Mara is what makes it unique, and the results obtained all over the world testify this. Laser and GPS system technologies give an unrivaled performance, in particular when they are used together.

Laser technology

Laser technology is applied to the levellers in a way that continually synchronize the height of the blade.
The laser leveller, the laser beam transmitter and the laser beam receiver are parts of the laser control system for levelling.
The transmitter is put on a tripod that sees the natural tilt of the soil and communicates the signal to the receiver, which is instead positioned on the machine itself.
The laser beam, beacuse of its internal characteristics, enables very high preciseness even over long land portions. After getting the signal, a technologically perfectioned rotating pentaprism, positioned on these machines, gives back an ideal program for the leveller to follow while operating.
The receiver also has an important role, because it correctly reads the laser light received from the transmitter, through special photodiodes. The receivers, made by Mara Laser, guarantee the levellers will be able to work on any kind of soil and receive the 360° signal, though it could be poor or experiences interference.
On the laser leveller, moreover, there is a control system to remove external interference. It lowers wind rumble, automatically captures the signal and sets the power of the tractor.

GPS system technology

GPS technology, after all, is used to settle the position of the laser leveller and the height of the blade.
The levellers, that adopt this technology, perceive the laser signal from the satellites: even in this situation the program is illustrated by the signal and reproduced on the soil.
Lately, thanks to technological progress and the use of dedicated software, an accuracy of ± 10 mm has been reached up, even though this technology offers minor accuracy than laser technology: GPS systems are subject to fluctuations beacuse of the periodic change of constellation of the satellites.
In any case, the minor preciseness is compensated by the wide elasticity of use, in particular when this technology is used to work on large parts with various inclinations, such as agricoltural ground and building constructions.

Integrated laser + GPS system

Mara Laser has created and made an integrated system that matches the precision of laser technology with the potential of GPS, perfect for harsh soil.
The higher preciseness of the laser signal shows the plan within a radius of 1300 meters, while the GPS system communicates the place of the leveller. Thus, the Mara system can settle the height of the tractor leveller and the place of the blade itself.
The creation of the 3D map of the soil enables to highlight the parts that has to be scraped, the loading areas, the point where to start, and the best route that enables to make the best work possible, with both the tractor and the leveller in the right position.
Thus, the operator will have immediate instructions through the constant updating of the data by the system.

Fields of application

The considerable preciseness and elasticity of the levellers made by Mara Laser secure their use in various fields:

  • Laser levelling machines for agriculture:
    Mara’s laser levellers, among the many plus secure a key increase of the arable parts. They permits a reduction in the amount of water used, they can provide more abundant harvest, a less use of chemicals, as well as seeds. The decrease in work hours, furthermore, makes the use of these machines a sure investment.
  • Laser levelling machines for construction:
    Mara Laser gives a perfect precision to obtain ground floors with very contained deflections (max 4 mm) and to remove cavities and gaps that would, later, be filled with concrete. The decrease of work hours and the possibility of obtaining a perfect slope for water to flow down, are other plus that make these machines worthy and priceless in this fields.
  • Laser levelling machines for earth-moving:
    the first-rate performance of the Mara levellers enables to move large amount of soil very quickly and with low power. In this way, shorter work hours, lower costs and greater preciseness in creating the horizontal plan and tilt, are attained.
  • Laser levelling machine for sportsground:
    this type of technology can be utilized very well in this area as it makes possible to level even existing sectors, repairing soil depressions without replacing the lawn.
  • Laser levelling machines for greenhouses:
    thanks to the preciseness, contained size and easy handling of Mara laser levellers, it is also doable to work for the maintenance of green spaces. In this way, the right tilt and also a great aesthetic result are assured.
  • Laser grader machines for roads:
    in this area, important results are attained thanks to the capacity of the Mara’s laser graders to perform the same job as the motor grader, with minor costs and more convenient times. In addition, there are key plus, for example specialized labor is no longer necessary, on top to the fact that the use of fine materials is reduced.
