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.

|u-drill fold||6.0m||4350 litres|
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
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.
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

Depth guidance and press wheels 380 x 65mm to guarantee the best “seed–to–soil” contact and establishing a capillary system.
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.
