This universal seed drill combination Kverneland u-drill plus is available in working widths of 3.0m, 4.0m rigid and 4.0m and 6.0m folding. The Kverneland u-drill plus carries out seedbed preparation, levelling, reconsolidation, seeding, fertilising and pressing in one pass - featuring high efficiency, large performance and high hectare output as main characteristics. The “plus” stands for the extra feature of the grain and fertiliser version to apply either grain and fertiliser or, alternatively, two different sorts of seeds at the same time. This has been achieved by the divided hopper equipped with two metering devices.
Depending on the working width of this universal trailed seed drill combination, the hopper capacity is either 3000l (3m and 4m) and 4350l (6m). The hopper of the rigid u-drill plus is divided lengthwise and the two metering devices are accordingly positioned either side. The proportion is 40 : 60.
The Kverneland u-drill plus is able to deliver fertiliser application rates up to 400kg/ha and 15kph. The pressurised hopper system of the u-drill 6m fold ensures that these rates are maintained even under the most difficult conditions.
In order to balance the shorter vegetation phase, the phosphoric fertiliser application supports the initial germination and development of the plants in the most efficient way. In trials of spring sown crops, yields have shown increases up to 25% compared to crops where the fertiliser has been applied by other methods.
In addition, in current farming processes flexibility and strong performance are requested since the application of two different seeds in one pass has become more and more popular. The second crop mainly developing after the harvesting of the main crop.
Step 1: Level the soil
For the best possible preparation, the front tyre packer levels the soil, crushes large clods and thus paves the way for the optimum depth control of the following tools. The front tyre packer has a diameter of 800mm. When it is not needed, it can be lifted hydraulically, simply by pushing a button..
Step 2: Prepare the seedbed
The disc harrow section consists of two rows of aggressively pitched conical discs. The discs are 5mm thick and hardened for long life. Thanks to their conical shape, the cutting angle remains constant. The high rotation speed ensures an excellent cutting quality over the entire working width. The distance between the sowing rows can be 12.5or 16.7cm.
The MD disc section consists of two rows of straight waved discs. The MD disc have been designed for vertical penetration through the flutes. The blade keeps turning, penetrating and cutting even in the most challenging conditions. A seedbed is created only in stripes of 3 to 5 cm in width, in which the seed is placed by the CD coulter.
The MD disc section is available for machines with 16.7 cm row distance and with the u-drill plus in combination with double entry fertiliser injection.
Step 3: First pack, then seed
For perfect depth control of the coulters and an optimum seed-to-soil contact providing excellent capillary action, the loosened soil is re-compacted by a large tyre packer. The large tyre diameter of 900mm significantly reduces the tractive power required by the machine and thus ensures a consistently good work result.
Step 4: Drill and pack at constant seeding depth
The narrow profile of the coulters with their slightly offset steel discs allow easy penetration into the soil. Thus, little pressure is required at this point with only little soil being displaced. The coulter pressure of 100kg can, therefore, be primarily used for the pressing by the integrated press wheels. The result: a uniform seeding depth even at high working speeds! The seeding depth and the coulter pressure can be centrally controlled by the push of a button from the tractor cab – this saves additional time.
The stable depth control and the pressing of the seed produce a capillary system in the soil that ensures access to water and excellent germination
Step 5: Closing
Harrowing the soil completes the drilling. S-shaped or finger harrows ensure an optimum covering of the seeds. The working intensity can be set by the stepless pressure adjustment and at three different angles. To prevent damage to the harrow when reversing, it is equipped with an effective reversing device.
The u-drill comes with a fully automated headland management system. This saves the driver lots of time and eases the operation. Using just one button, the driver can initiate a headland sequence with wheels, discs and coulter bar all capable of automatic operation in timed stages. The lifting sequence starting with the disc section ensures a constant depth control until the headland.
As the headland sequence starts, the metering device stops automatically – avoiding double seeding. The seed hoses are empty at the headland. This saves up to 5% of seed.
The driver can concentrate on steering the machine and the correct operation. In addition double and/or missed seeding is prevented. With headland management the job can be done more quickly, precisely and efficiently. The drill requires only one double-acting spool to operate.
- ELDOS is electric driven by e-com and is fully ISOBUS compatible.
- GEOCONTROL by GPS signal is possible which avoids double seeding.
- Special sensors ensure functionality from the tractor cab.
- Five standard rotors are delivered: for fine and large seeds or fertiliser.
- The exchange of the rotors is quickly and easily done without any tools.
- Application rates from 1 to 400kg/ha are possible (depending on working speed and width).
- The metering device is always easily accessible.
- Very simple calibration test due to the separate seed guidance.
- A remote control allows the driver to operate the calibration process at the metering device.
- No gear has to be adjusted. The driver simply enters the desired values into the terminal, presses one button to start at the metering device and that’s it.
- The calibration is done automatically.
- A calibration flap with an integrated gate prevents any seed from dropping into the hose.
The u-drill plus has been designed for precise fertiliser placement whilst sowing. It is able to apply fertiliser rates up to 400kg/ha (depending on speed and width). The pressurised hopper system of the 6.0m version ensures that these rates are maintained even under the most difficult conditions. Depending on the individual agronomic requirements, the fertiliser can be applied either directly in the seeding row or in between two rows.
Fertiliser placement within the disc harrow section
The outlets within the second row of the disc harrow section apply the fertiliser exactly in between two sowing rows. All plants have exactly the same distance to the incorporated fertiliser placed. By adjusting the working depth of the disc harrow, the depth of the fertiliser placement is determined.
Fertiliser placement within the seeding row
The fertiliser application within the seeding row is done by the double-entry CD coulter. The fertiliser is placed together with the seeds. This is especially suitable for phosphoric fertiliser in order to support the initial germination and development of the plants in the most efficient way.
Sowing of two different crops
The special design of the double-entry CD coulter with two exits also allows the sowing of two different crops in just one working pass.
