Subsoilers model 707-813 made by DONDI (Italy)

Basic equipment:

• Type:
  Mounted subsoiler, designed for autumn tillage after harvesting grain and industrial crops (sunflower, corn, rapeseed, etc.). An alternative to plowing, the machine allows loosening up to depths up to 60 cm. The main functions of tillage are: destruction of the plow pan, creation of uniform soil density, mixing of crop residues with the top layer of the earth to create moisture and snow retention.

• Frame:
  With three crossbeams and strong reinforcements. For tough working conditions. Amplifiers and racks are attached to the beams with the help of stepladders. Category III three-point linkage in front, mount for additional equipment rollers in the back

• Stands:
  Rigid  high-strength steel steel with safety mechanism -shear bolt (tensile work) that prevents breakdown of the machine. Tips of racks have bolt fastening for replaceable chisels. The chisels are reversible; when one side is worn, they turn over.  Supplied with side wings for more efficient and uniform loosening.

• Packers: double
  gear, with mechanical adjustment (models 809, 811, 813 with hydraulic
  adjustable), installed at the back.

• Fertilization: allows you to simultaneously apply granular fertilizer under the anchor leg while deep loosening. The bunker is mounted on a frame (it is possible to complete the old subsoilers with an application system). The application rate is regulated by an electronic hydraulically driven dispenser (as standard). Connection of the 1st hydraulic port of the tractor is required. The rate is regulated within 50 – 390 kg/ha.

• WEIGHT, kg — 1840.0 (model 707), 2490.0 ( Model 807), 2670.0 (Model 807 with fertilizer), 3100.0 (Model 809), 3310.0 (Model 809 with fertilizer), 4750.0 (model 811), 5900.0 (model 813).
