Laser levelling machines for agricultural soil

Mara Laser is a business activity that for 30 years and more has been analyzing, producing and marketing laser and GPS controlled laser levelling machines, calling on buyers in about 30 states everywhere in the world.
Thanks to GPS and laser control technologies, we can reach outstanding results in different sectors of use: from agricoltural ground to sport courts, from building constructions to road excavations, from landscaping to soil scraping.
Mara’s levellers ensure a series of returns and high productivity in various situations: from the machine running speed regime, to a total affidability and certainty of the result.

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 receiver 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 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 positioned on a tripod that sees the natural inclination of the land and sends the signal to the receiver, which is instead mounted on the machine itself.
The laser beam, as it is one of its internal characteristics, permits very high preciseness even over long sections of land. After obtaining the signal, a technologically perfectioned rotating pentaprism, mounted on these machines, gives back an ideal pianification for the leveller to follow while running.
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 kind of ground and receive the 360° signal, though it could be poor or experiences interference.
On the laser leveller, also, there is a control system to remove external interference. It decreases wind sound, automatically captures the signal and sets the power of the tractor.

GPS receiver technology

GPS technology, after all, is used to settle the position of the laser leveller and the height of the blade.
The levellers, that implement this technology, perceive the laser signal from the satellites: even in this situation the pianification is illustrated by the signal and reproduced on the land.
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 as it is one 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 land portions with various inclinations, such as agricoltural ground and building constructions.

Integrated laser + GPS system

Mara Laser has produced and manufactured an integrated system that adds the precision of laser technology with the potential of GPS, perfect for harsh land.
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. Therefor, the Mara system can settle the height of the tractor leveller and the location of the blade itself.
The creation of the 3D map of the land permits to highlight the land portions that has to be scraped, the loading areas, the starting point, and the best way that enables to do the greatest job possible, with both the tractor and the leveller in the right position.
Therefor, the operator will have instant 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 assure their use in various areas:

  • Laser levelling machines for agriculture:
    Mara’s laser levellers, among the different benefits assure a key increase of the arable land portions. 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 provides a perfect precision to obtain ground floors with very contained deflections (max 4 mm) and to remove cavities and gaps that would, afterwords, be filled with concrete. The decrease of work times and the possibility of obtaining a perfect slope for water to flow down, are other benefits that make these machines incomparable and incomparable in this areas.
  • 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 inclination, are achieved.
  • Laser levelling machine for sportsground:
    this type of technology can be utilized very well in this field as it enables 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 levelling machines, it is also doable to work for the maintenance of green spaces. In this way, the right inclination and also a great aesthetic result are assured.
  • Laser grader machines for roads:
    in this field, important results are achieved thanks to the capability of the Mara’s laser graders to provide the same job as the motor grader, with minor costs and more convenient times. In addition, there are key benefits, for example specialized labor is no longer needed, besides to the fact that the use of fine materials is reduced.
