To provide an aggressive working angle but with maximum penetration force, the seed discs are mounted in an OffSet position. Spirit is able to reach the desired working depth irrespective of soil type or conditions on the field.
The large diameter seed discs offer a smooth ride, whilst the robust V-55 Swedish steel provides an extremely long working life.
OffSet seed discs
To effectively prepare the seedbed, Spirit is equipped with heavy-duty front tools. The individually mounted discs provide perfect precision and throughflow. The conical shape of the discs create a high degree of fine tilth, important for the seed-to-soil contact. The front tools can be adjusted from the cab on the move. Since the front tool is mounted on a parallel linkage, an even working angle is guaranteed irrespective of working depth. For levelling an individually adjustable CrossBoard can be mounted ahead of the disc tool.
To ensure a firm seedbed, large packer wheels consolidate the soil prior to seed placement. Each individual seed coulter has a wide coulter press wheel. This allows the seed coulters to respond to any irregularities or soil variations on the field, thereby ensuring the working depth is constantly maintained. The generous diameter of the coulter press wheel, further results in a smooth ride with minimal impacts from vibrations, thereby increasing precision at high speed.
A rapid and even emergence provides the crop with considerably higher competitiveness against weeds, this is especially important as more herbicide resistant weeds are on the increase. Research show that 125mm row spacing result in 20% less weeds than 150mm. A narrow row spacing allows for a larger seed spacing, thereby lowering the fungi pressure. The rapid and even emergence leads to lower evaporation, at a time when the access to moisture is most crucial.
By equipping Spirit R 300S with SeedEye blockage monitoring, the seeding can be visualised in real time.
The active coulter pressure ensures an impressive depth control. With sensors in the hydraulic system, the machine immediately compensates for any rise or dip in the field.
Seed is metered by two Fenix III units, each metering one half of the machine, this enables half machine shut-off from the cab.
Headland management increases precision
The pivot packer consolidates the soil between the tractor wheels enabling each seed to have the same conditions for germination.
The pivoting function minimises soil drag on the headland.
One important feature of Fenix III is the soft rotor that seals the system and lowers the air requirement, in turn saving diesel.
Fenix III achieves great precision which leads to an even emergence.
The coulter pressure is maintained at the pre-set value, irrespective of coulter working angle in relation to the rest of the machine.
