Sowing is one of the fundamental factors for the successful establishment and subsequent productivity of the crop, therefore, seeders play an important role within the production process, as the productivity of a crop is significantly affected by the planting stand. plants, mainly due to the variation in the uniformity of seed distribution in the sowing furrow.

It is during planting that the productive potential of crops is defined. Planting a crop must be very well planned, as it determines the beginning of a process lasting around 120-140 days that will affect all operations involved, in addition to determining the possibilities success or failure of the crop.

Sowing must enable rapid and uniform establishment of the desired plant population. To achieve this, the seeder must create a favorable environment for the seed to come into close contact with the soil, enabling the absorption of water, essential for the beginning of the germination process, in addition to promoting the appropriate dosage of seeds to obtain the population. ideal number of plants/ha.

The importance of the planting operation can be analyzed from two aspects: financial and qualitative.

Regarding the financial aspect, it is noteworthy that it is during the planting operation that a large part of the production costs used in running a crop are allocated. In the case of soybeans, 69,6% of the total inputs used in the crop are applied during planting; 41,9% of the labor required to conduct the crop is used in planting and 15,9% of the operational cost of the crop is applied to the planting operation, so it can be stated that 47,7% of the total cost of the soybean crop is allocated during the sowing operation. In the case of corn, the costs allocated during planting reach 49,6% of the total cost of the crop.

Regarding the qualitative aspect, it must be considered that the quality of planting is influenced by several factors, among which the following stand out: the physical and physiological quality of the seeds, the seeder, planting speed, soil cover ( straw) and soil condition.

In the specific case of implementing different crops under the Direct Planting System (SPD), seeders play a fundamental role in the development of the process, for this purpose the machine has to perform five basic functions:

- cut the straw,

- open a furrow for fertilizer and seed deposit;

- distribute fertilizers and seeds in adequate quantities;

- deposit seeds and fertilizers in the soil at an appropriate depth;

- cover the groove.


NEWLAND FULL is a 100% pneumatic tiller, intended for Direct Planting of large grains on medium and large properties that meets the needs and requirements of the main crops. It features high technology on board to provide greater quality in the implementation of crops.

The technological package includes the unprecedented central fertilizer box system, as well as a central seed box, ISOBUS system and seed distribution through a pneumatic system.

Available in individual models of 13,15 and 17 lines with a spacing of 45cm and 22, 26, 30 and 34 lines using two coupled machines.

Fewer lubrication points, less maintenance and greater agility and speed in supplying fertilizer and seed result in high operational performance.

NEWLAND FULL was developed to provide greater efficiency in the sowing operation, combining greater planting quality and greater operational productivity (yield) in Direct Planting of large grains.

The quality of planting can be reflected by the use of pantograph sowing lines and the use of a pneumatic distributor Vacuum System to distribute the seeds, which is driven by the flexible cable system, ensuring precise and uniform movements of the distributing disc.

The great advantage of the machine is the use of a central fertilizer box where the distribution of the product is carried out by the Semeato Multi Doser – MDS, combined with the pneumatic system to guide the product to the lines, with high precision and low maintenance. In this system, the fertilizer is deposited in the central reservoir which has a single rotor at its lower base that is responsible for dosing the desired amount of fertilizer. When passing through the rotor, the product falls into a duct through which air flow generated by a turbine passes. The fertilizer is then taken to the manifold (hat) where division occurs for each of the machine lines. After passing through the 'hat', the product continues to be carried by the air flow to the lines.

The transmission of fertilizer and seed distribution mechanisms is carried out using hydraulic motors. The system is made up of high-torque, low-speed motors, providing continuous rotation movements, thus improving the uniformity of seed and fertilizer distribution.

The machine is equipped with the system ISOBUS - International Standard for Electronic Communication between different machines from different manufacturers. This system controls transmission, making it possible to change seed and fertilizer dosages with a simple touch of the screen.

The system ISOBUS allows the same tractor console to be used to control the planter, with no need to install other equipment on the tractor.

With this system, the machine is prepared to make variable rate applications of both fertilizer and seeds. For this, the tractor console must also be prepared.

Currently, seeds carry a very large technological “load”, so there is no point in purchasing the 'best' seed if, when distributing them in the soil, they are “mistreated”.

The success of a crop is the result of the sum of several factors, which, together, will determine the profit or loss, some under human control, others not.

The use of agricultural machinery and equipment, when done correctly, in addition to resulting in crops with high production potential, improves operational efficiency and increases effective work capacity, thus facilitating farmers' tasks.

When considering that it is during planting that the production potential of crops is defined, it is possible to state that the seeder is the most important equipment within the machinery park of a grain producing property.
