Grimme presents a new generation of its 12- and 18-row Matrix precision seeder for seed beets, canola and root chicory. The machine features a compact design, optimised weight distribution and increased driver relief in terms of adjustment options and assistance systems. A version with hydraulic pressure support and spraying track marking is the latest addition.
Modularity, weight optimization and precise spacing of the seed were at the forefront of the revision of the seeding unit. The parallelogram, which guides the single-row seeding unit in depth, is now made of hardened cast aluminum. The lower weight combined with increased rigidity ensures improved adaptation to the ground contour. In addition, acting forces can be better dissipated. Another new feature is that the parallelogram is equipped with maintenance-free plastic bearings. The increasing importance of mechanical weed control makes a precise, central placement of the seed in the row necessary. The newly revised parallelogram meets these requirements in a perfect way, thanks to its true-to-gauge seed-placement.
The new seed hopper has a lid that protects the seed against dust and water and can be closed tightly with a spring-loaded snapper.
The machine has a new optical sensor, which is now protected inside the seeding coulter. The sensor reliably detects and counts beet, canola and root chicory seed – even under difficult conditions. Furthermore, the new sensor reliably indicates possible blockages of the seeding coulter to the driver.
Thanks to the modular design of the single-row seeding unit, it can be converted from conventional seeding to mulch seeding. The row spacing can also be changed from 50 cm to 45 cm. The two setting options are particularly advantageous if the cultivation method changes over time due to new requirements.
Intelligent operating and assistance systems
For precise seed placement at different driving speeds, a radar sensor for slip-free speed detection was installed centrally under the main frame. Alternatively, the tractor’s speed signal can be used. With the intuitive Grimme Digital Interface (GDI), operators can quickly find their way around and have all adjustable parameters at their fingertips. To maximize yield and save seed, Clever Planting is on board as standard and Section Control is available as an option.
This is new in connection with the so-called MATRIX seed: Within the machine width, each individual seed is placed in a triangular formation for an optimised crop distribution.
Another new feature is the creation of so-called turnpike-rows. This method increases the seeding rate in defined rows towards the edge of the field. This limits possible feeding damage to the outer rows, which at the same time promotes a homogeneous crop in the centre of the field until harvest.
With a view to the harvest, it is already possible to create so-called ‘harvest windows’ during seeding. This means that seeding is interrupted for a certain area. The resulting marking helps the harvester driver to find the right match of (6-12-18) rows in relation to the seeding process, increases harvesting efficiency and provides additional relief and driving comfort.
Hydraulic, infinitely adjustable pressure support
With the Matrix’s hydraulic pressure support, the additional pressure on the seeding coulter can be adjusted continuously and conveniently from the operator terminal from 0 to 120 kg per seeding unit. As an option, an additional 20 % coulter pressure can be applied to the seeding units which run in the tractor track to ensure smooth running of the machine and precise placement of the seed.
Both the pressure adjustment of the individual seeding units and the spraying track marking are fully integrated into the Grimme Digital Interface (GDI) software, enabling simple and intuitive operation. The machine can be operated via load-sensing or via a double acting hydraulic control box.
The new Matrix has an optional telemetric-unit so that information and parameters can be transmitted to the web-based end customer portal myGRIMME. The new myGRIMME functions such as ‘Fields’, i.e. field-related documentation and visualisation, and ‘Crops’, i.e. capturing and documentation of different varieties, can now be used.
