Levelling machines for tractors

Mara Laser is a business company that for 30 years and more has been examining, making and trading laser and GPS controlled levellers, calling on buyers in about 30 nations everywhere in the world.
Thanks to GPS and laser control technologies, it is feasible to achieve important results in different sectors of utility: from agricoltural ground 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 running velocity, to a total affidability and assurance of the result.

Mara’s technology

The technology used by Mara is what makes it unbeatable, and the results acquired all over the world witness this. Laser and GPS receiver technologies give 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 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 sees the natural tilt of the soil and communicates the signal to the receiver, which is instead put on the machine itself.
The laser beam, for its own 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 planning 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, made 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 poor or it is subjected to interference.
On the leveller, moreover, there is a control system to annul external interference. It decreases wind rumble, automatically intercepts the signal and sets the power of the tractor.

GPS receiver technology

GPS technology, after all, is used to regulate the position of the leveller and the height of the blade.
The levellers, that adopt this technology, obtain the laser signal from the satellites: even in this situation the planning is represented by the signal and reproduced on the soil.
Lately, thanks to technological advancement 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 for 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 parts with more than one inclinations, such as agricoltural ground and building constructions.

Integrated laser + GPS system

Mara Laser has produced and made an integrated system that matches the precision of laser technology with the potential of GPS, the right one for harsh soil.
The higher preciseness of the laser signal shows the plan within a radius of 1300 meters, while the GPS system communicates the precise spot of the leveller. Therefor, the Mara system can regulate the height of the tractor leveller and the precise spot 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 point where to start, and the best route 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 important preciseness and elasticity of the levellers made by Mara Laser ensure their use in more than one areas:

  • Laser levelling machines for agriculture:
    Mara’s laser levellers, among the different conveniences ensure a important increase of the arable parts. 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 decrease in work hours, besides, 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 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 a perfect slope for water to flow down, are other conveniences that make these machines worthy and priceless 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 hours, lower costs and greater preciseness in creating the horizontal plan and tilt, 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 sectors, repairing soil depressions without replacing the lawn.
  • Laser levelling machines for greenhouses:
    thanks to the preciseness, reduced 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 great aesthetic result are assured.
  • Laser grader machines for roads:
    in this field, important results are reached thanks to the skills 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 important conveniences, for example specialized labor is no longer necessary, on top to the fact that the use of fine materials is reduced.
