Battery operated heavy disc harrow, two-row folding Demetra BDTS series, model BDTS-6,3

The BDTS series harrows are designed for surface tillage to a depth of up to 18 cm, shredding crop residues and weed killing.
The working bodies of the harrow are spherical discs with cutouts assembled in a battery. Each battery is mounted on two stands with an inclination to the vertical. The upper part of the stand is shaped, closed with a shaped cover, and elastomers are located in the corners of the formed quadrilateral. The presence of elastomers reduces shock loads on the bearings and allows the disc battery to bypass insurmountable obstacles. Differences of the Demetra® BDT and BDTS harrows compared to two-row disc harrows with discs on an individual stand:
Battery harrows are easier to set up and maintain the implement and contain fewer bearing units.
In order to keep costs down, the Demetra® BDT and BDTS harrow (Patent No. 2756406) is made as simple as possible. No packer rollers. No unnecessary hydraulic cylinders.
