GPS levellers for tractors

Mara Laser is a business company that for over 30 years has been analyzing, producing and marketing laser and GPS controlled laser levellers, calling on buyers in about 30 nations all over the world.
Thanks to GPS and laser control technologies, we can get to outstanding results in different sectors of use: from agricultural soil to sportsground, from building constructions to road excavations, from landscaping to soil scraping.
Mara’s levellers ensure a series of returns and high capacity in more than one situations: from the machine operating velocity, 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 acquired all over the world witness this. Laser and GPS system technologies provide an unique performance, in particular when they are used together.

Laser technology

Laser technology is applied to the levellers in a way that without stopping synchronize the height of the blade.
The leveller, 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 observes the natural inclination of the soil and communicates the signal to the receiver, which is instead mounted on the machine itself.
The laser beam, for its own characteristics, enables very high preciseness even over long sections of land. After picking up the signal, a technologically perfectioned rotating pentaprism, mounted on these machines, gives back an ideal planning for the leveller to follow while operating.
The receiver also plays a very important part, 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 type fo ground and receive the 360° signal, even if it could be low or it goes through interference.
On the leveller, besides, there is a control system to annul external interference. It decreases wind rumble, automatically reaches the signal and settles the power of the tractor.

GPS system technology

GPS technology, however, is used to set the position of the leveller and the height of the blade.
The levellers, that implement this technology, get the laser signal from the satellites: even in this situation the planning is illustrated by the signal and reproduced on the soil.
Nowadays, thanks to technological progress and the use of dedicated software, an accuracy of ± 10 mm has been reached up, even though this technology offers poorer accuracy than laser technology: GPS systems are subject to fluctuations for the periodic change of constellation of the satellites.
In any case, the poorer preciseness is compensated by the wide adaptability of use, in particular when this technology is used to work on large land portions with more than one inclinations, such as agricultural soil and building constructions.

Integrated laser + GPS system

Mara Laser has produced and manufactured an integrated system that connects the precision of laser technology with the potential of GPS, suitable for harsh soil.
The higher preciseness of the laser signal lays out the plan within a radius of 1300 meters, while the GPS system communicates the place of the leveller. Thus, the Mara system can set 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 land portions that has to be scraped, the loading areas, the section where to begin, and the best route that enables to do the greatest job 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 outstanding preciseness and adaptability of the levellers manufactured by Mara Laser secure their use in more than one fields:

  • Laser levelling machines for agriculture:
    Mara’s laser levellers, among the different plus secure 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 less use of chemicals, as well as seeds. The decrease in work hours, besides, 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 reduced deflections (max 4 mm) and to annul cavities and gaps that would, afterwords, be filled with concrete. The decrease of work hours and the possibility of obtaining an absolute perfect inclinatoin for water to flow down, are other plus that make these machines priceless and priceless in this fields.
  • Laser levelling machines for earth-moving:
    the first-rate 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 inclination, are gained.
  • Laser levelling machine for sportsground:
    this type of technology can be used 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, reduced 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 inclination and also a fabulous aesthetic result are secured.
  • Laser grader machines for roads:
    in this area, important results are gained thanks to the capacity of the Mara’s laser graders to provide the same job as the motor grader, with poorer costs and more convenient times. In addition, there are important plus, for example specialized labor is no longer necessary, on top to the fact that the use of fine materials is reduced.
