Kverneland u-drill

The u-drill - the universal seed drill combination

The u-drill is a trailed seed drill combination available in 3.0m, 4.0m rigid and 6.0m folding working width to carry out seedbed preparation, levelling, reconsolidation, seeding and pressing in one pass.The focus in design has been especially given to high speed operation (10-18km/h) whilst ensuring a perfect seed placement.

The hopper can easily be filled using big bags and a front loader or telescopic handler. For the 6m version a filling auger is available. The hopper has a capacity of 3,000l (3/4m) respectively 4,350l (6m).

The u-drill is extremely user-friendly: Being of course fully ISOBUS compatible, the driver is in full control of all data.  The u-drill is ready for GEOCONTROL in order to control application rate and half-width shut-off. In addition, only one double-acting valve ensures the fully automatic controlled head-land-management.

Highlights

u-drill - Front Wheel Packer

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.. 

u-drill - Disc Harrow

Step 2: Prepare the seedbed

Two rows of  the well-proven short disc harrow with its conical disc shape and individual suspension ensures a fine and uniform seedbed over the entire working width. Thanks to a new hydraulic system, the disc harrow can be adjusted with continuous variability from the cab.

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.

u-drill - CD-coulter

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.

u-drill – Headland Management

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 - the metering device

  • 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.
  • Four standard rotors are delivered for fine and large seeds or fertiliser.
  • A fifth rotor is offered as an option for maize, sunflowers and greening seeds.
  • The exchange of the rotors is quick 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. 

Calibration

  • 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.
