Mara - Laser Levelers

Laser leveller blades for agricultural soil

Mara Laser is a business company that for over 30 years has been examining, making and marketing laser and GPS controlled laser levellers, turning towards clients in about 30 states everywhere in the world.
Thanks to GPS and laser control technologies, we can get to outstanding results in many areas of use: from agricultural soil 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 functioning velocity, 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 unrivaled performance, in particular when they are combined.

Laser technology

Laser technology is applied to the levellers in a way that without stopping synchronize the height of the blade.
The laser levelling machine, the laser beam transmitter and the laser beam receiver are parts of the laser control system for levelling.
The transmitter is placed on a tripod that observes the natural inclination of the land 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 accuracy even over long land portions. After getting the signal, a technologically perfectioned rotating pentaprism, mounted on these machines, gives back an ideal pianification for the leveller to follow while functioning.
The receiver also plays a very important part, 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 ground 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 lowers wind rumble, automatically captures the signal and regulates the power of the tractor.

GPS receiver technology

GPS technology, however, is used to set the position of the laser levelling machine 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 illustrated by the signal and reproduced on the land.
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 less accuracy than laser technology: GPS systems are subject to fluctuations for the periodic change of constellation of the satellites.
In any case, the less accuracy is compensated by the wide adaptability of use, in particular when this technology is used to work on large parts with various inclinations, such as agricultural soil 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, the right one for tough land.
The higher accuracy of the laser signal lays out the plan within a radius of 1300 meters, while the GPS system communicates the location of the leveller. Thus, the Mara system can set the height of the tractor leveller and the location of the blade itself.
The creation of the 3D map of the land enables to highlight the parts that has to be scraped, the loading areas, the section where to begin, and the best way that enables to make the best work possible, with both the tractor and the leveller in the right position.
Thus, the operator will have prompt instructions through the constant updating of the data by the system.

Fields of application

The outstanding accuracy and adaptability 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 important 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 times, 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, afterwords, be filled with concrete. The decrease of work times and the possibility of obtaining an absolute perfect slope for water to flow down, are other plus that make these machines worthy and incomparable in this fields.
  • Laser levelling machines for earth-moving:
    the superbe performance of the Mara levellers enables to move large amount of soil very quickly and with low power. In this way, shorter work times, lower costs and greater accuracy in creating the horizontal plan and inclination, are reached.
  • Laser levelling machine for sportsground:
    this type of technology can be utilized very well in this field as it makes possible to level even existing areas, repairing slope without replacing the lawn.
  • Laser levelling machines for greenhouses:
    thanks to the accuracy, contained size and easy handling of Mara laser levellers, it is also feasible to work for the maintenance of green spaces. In this way, the right inclination and also a great aesthetic result are secured.
  • Laser grader machines for roads:
    in this field, important results are reached thanks to the skills 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 plus, for example specialized labor is no longer necessary, besides to the fact that the use of fine materials is reduced.
