GPS laser levellers for tractors

Mara Laser is a business activity that for over 30 years has been analyzing, making and trading laser and GPS controlled laser levellers, turning towards clients in about 30 states everywhere in the world.
Thanks to GPS and laser control technologies, it is feasible to achieve significant results in different sectors of use: from agricoltural ground to sport courts, from building constructions to road excavations, from landscaping to ground scraping.
Mara’s levellers ensure a series of advantages 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 unbeatable, and the results obtained all over the world are proof of this. Laser and GPS system technologies give an unrivaled performance, mostly 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 leveller, the laser beam transmitter and the laser beam receiver are the elements of the laser control system for levelling.
The transmitter is placed on a tripod that examines the natural tilt of the soil and communicates the signal to the receiver, which is instead put on the machine itself.
The laser beam, beacuse of its internal characteristics, permits very high preciseness even over long land portions. After picking up the signal, a technologically perfectioned rotating pentaprism, put on these machines, returns an ideal pianification 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, manufactured by Mara Laser, guarantee the levellers will be able to move on any kind of soil and receive the 360° signal, even though 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 sets the power of the tractor.

GPS system technology

GPS technology, however, is used to settle 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 pianification is defined 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 obtained, 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 adaptability of use, mostly 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 manufactured an integrated system that connects the precision of laser technology with the potential of GPS, proper for tough soil.
The higher preciseness of the laser signal represents 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 permits to highlight the parts that has to be scraped, the loading areas, the starting point, and the best way that allows 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 significant preciseness and adaptability of the levellers manufactured by Mara Laser ensure their use in various fields:

  • Laser levelling machines for agriculture:
    Mara’s laser levellers, among the different conveniences ensure a key increase of the arable parts. They enable a reduction in the amount of water used, an increased production, a less use of chemicals, as well as seeds. The decrease in work times, moreover, 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 annul cavities and gaps that would, later, be filled with concrete. The decrease of work times and the possibility of obtaining a perfect inclinatoin for water to flow down, are other conveniences that make these machines worthy and incomparable in this fields.
  • Laser levelling machines for earth-moving:
    the fine performance of the Mara levellers permits to move large quantity of soil very quickly and with low power. In this way, shorter work times, 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 used very well in this area as it enables to level even existing sectors, repairing slope 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 fabulous aesthetic result are secured.
  • Laser grader machines for roads:
    in this area, important results are attained thanks to the skills 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 conveniences, for example specialized labor is no longer necessary, besides to the fact that the use of fine materials is reduced.
