GPS leveller for agricultural soil

Mara Laser is a business company that for over 30 years has been examining, producing and trading laser and GPS controlled levellers, turning towards buyers in about 30 nations all over the world.
Thanks to GPS and laser control technologies, we can get to outstanding results in many areas of utility: from agricoltural ground to sport facilities, 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 running 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 are proof of this. Laser and GPS receiver technologies provide an unrivaled performance, in particular when they are combined.

Laser technology

Laser technology is applied to the levellers in a way that continually synchronize the height of the blade.
The laser levelling machine, the laser beam transmitter and the laser beam receiver are the elements of the laser control system for levelling.
The transmitter is located on a tripod that sees the natural tilt of the soil and sends the signal to the receiver, which is instead positioned on the machine itself.
The laser beam, beacuse of its own characteristics, enables very high preciseness even over long land portions. After obtaining the signal, a technologically perfectioned rotating pentaprism, positioned on these machines, gives back an ideal pianification for the leveller to follow while running.
The receiver also has an important role, because it correctly reads the laser light received from the transmitter, through special photodiodes. The receivers, manufactured by Mara Laser, guarantee the levellers will be able to move on any kind of soil and receive the 360° signal, though it could be low or it goes through interference.
On the laser levelling machine, also, there is a control system to remove external interference. It cuts wind sound, automatically reaches the signal and regulates the power of the tractor.

GPS receiver technology

GPS technology, after all, is used to regulate the position of the laser levelling machine and the height of the blade.
The levellers, that implement this technology, obtain the laser signal from the satellites: even in this situation the pianification is defined by the signal and reproduced on the soil.
Nowadays, thanks to technological advancement and the use of dedicated software, an accuracy of ± 10 mm has been reached up, even though this technology offers less accuracy than laser technology: GPS systems are subject to fluctuations beacuse of the periodic change of constellation of the satellites.
In any case, the less preciseness is compensated by the wide elasticity of use, in particular when this technology is used to work on large land portions with various inclinations, such as agricoltural ground and building constructions.

Integrated laser + GPS system

Mara Laser has created and manufactured an integrated system that matches the precision of laser technology with the potential of GPS, proper for harsh soil.
The higher preciseness of the laser signal represents the plan within a radius of 1300 meters, while the GPS system communicates the location of the leveller. Hence, the Mara system can regulate the height of the tractor leveller and the location of the blade itself.
The creation of the 3D map of the soil enables to highlight the land portions that has to be scraped, the loading areas, the starting point, and the best route that enables to do the greatest job possible, with both the tractor and the leveller in the right position.
Hence, the operator will have prompt instructions through the constant updating of the data by the system.

Fields of application

The outstanding preciseness and elasticity of the levellers manufactured by Mara Laser ensure their use in various fields:

  • Laser levelling machines for agriculture:
    Mara’s laser levellers, among the many benefits ensure a important increase of the arable land portions. They permits a reduction in the amount of water used, they can provide more abundant harvest, a considerable reduction of chemicals used, as well as seeds. The lowering in work hours, furthermore, makes the use of these machines a sure investment.
  • Laser levelling machines for construction:
    Mara Laser gives an absolute 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 lowering of work hours and the possibility of obtaining an absolute perfect inclinatoin for water to flow down, are other benefits that make these machines worthy and incomparable in this fields.
  • Laser levelling machines for earth-moving:
    the fine performance of the Mara levellers enables to move large quantity 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 achieved.
  • 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 areas, repairing soil depressions without replacing the lawn.
  • Laser levelling machines for greenhouses:
    thanks to the preciseness, contained size and easy handling of Mara levellers, it is also feasible to work for the maintenance of green spaces. In this way, the right tilt and also a fabulous aesthetic result are assured.
  • Laser grader machines for roads:
    in this area, important results are achieved thanks to the capacity of the Mara’s laser graders to perform the same job as the motor grader, with less costs and more convenient times. In addition, there are important benefits, for example specialized labor is no longer necessary, besides to the fact that the use of fine materials is reduced.
