The new disk-type cultivator-sower unit is dedicated to pre-sowing cultivation of soil during post-ploughing and post-stubble cultivation. The new model is designated U741/1 and its major characteristics include a service width of as much as 4 m. The machine is suitable for coupling with a drill sower.
Due to the extended service width, as compared with U741, the machine offers improved performance. Unit efficiency in this case is in the range 4 to 6.5 ha per hour. For comparison: the smaller variant of this model offers the performance in the range 3 – 5 ha per hour.
The unit is furnished with the set of 32 disks. Diameter of 30 disks is 510 mm. Two extreme (outer) disks are smaller, their diameter is 460 mm. Disks are mounted in two rows. The machine’s working depth is adjusted with a hydraulically-operated packer roller. The maximum working depth is 15 cm, which means 5 cm deeper penetration of soil. The machine is noticeably larger and heavier as compared with the smaller variant U741. Due to its larger dimensions the machine is to be operated with a tractor with a power output of 110 – 150 KM.
