Depending on the working width, the hopper capacity is either 3000l (3m and 4m) and 4350l (6m). The hopper of the rigid u-drill is divided lengthwise and the two metering devices are accordingly positioned either side. The proportion: grain and fertiliser is 40 : 60.
The u-drill plus is especially adapted to suite the need of precise fertiliser placement at the seed. These crops can show substantial yield increase when applying fertilser with a relatively high percentage of phosphate together with the seeds. In Scandinavian and Eastern European countries the fertiliser is usaually placed between the rows besides and below the seed, whereas in other countries e.g. Scotland the preferred method is to apply both seeds and fertilser in the same row. In trials of spring sown crops, yields have shown increasses up to 25% compared to crops where ther fertiliser has been applied by other methods.
The u-drill plus is able to deliver fertiliser application rates up to 400kg/ha and 15km/h. The pressurised hopper system of the 6m version ensures these rates are maintained even under the most difficult conditions.
|Working Width||Weight (kg) with front packer + track eradicators|
Working zone 1
A large front wheel packer (ø800mm) improves depth guidance throughout the machine and ensures good soil levelling.
Working zone 2
Two rows of aggressively pitched 18” conical disc harrow - well known from the Kverneland’ “Qualidisc”.
Working zone 3
Packing before seeding by a large off-set wheel packer (ø900mm)
Working zone 4
The new CD-coulter from Kverneland for uniform emergence at any seed depth and high speeds
Working zone 5
Depth guidance and press wheels 380 x 65mm to guarantee the best “seed–to–soil” contact and establishing a capillary system.
Working zone 6
Combing the soil completes the seeding. A choice of S-type/- or finger following harrow ensure an optimum covering of the seeds.
The intensity can be set via 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.
Depending on the individual agronomic requirements, the fertiliser can be applied either directly in the seeding row or in between two rows.
Fertiliser placement by the disc harrow
The fertiliser outlets in the second row of the disc harrow are allocated in such a way that the fertiliser line is applied exactly in between two sowing rows. All plants have exactly the same distance to the incorporated fertiliser depot. By adjusting the working depth of the disc harrow the depth of the fertiliser placement is controlled.
Fertiliser application in the seeding row
The fertiliser application in the seeding row is done by an extra fertiliser outlet. The fertiliser is placed in mixture 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. The special design of the coulter with two exits also allows the seeding of two different crops in just one working pass.
