Harvest preparation - Haulm topper | KS 75-4

4-row, for row widths from 75 to 80 cm

In order to promote uniform ripening of the tubers, haulm reduction can be carried out two to three weeks before harvesting. In addition to preventing the transmission of viral infections from the haulm into the tuber, a good skin set on the tubers can be achieved to improve storability. Instead of or as a supplement to chemical siccation, GRIMME offers a sustainable solution of haulm topping. By using a haulm topper, the haulm of the potatoes is mechanically crushed and deposited between the ridges. Careful placement of the haulm between the ridges is important. Epecially if the stems of the potato plants are to be treated with other herbicides afterwards. A further advantage is the reduced risk of blockage at the intake of the harvester and the resulting increased throughput capacity in case of extreme masses of haulm.

Uniform power transmission

The 4-fold V-belt drive ensures an even transmission of the required torque.

Cleaning made easy

Two large cleaning flaps allow an easy cleaning of the inside.

Single drive with free wheel

The freewheel in the drive train reduces the load on the PTO shaft and the drive shafts when disengaging at the headlands.

Height adjustable

The support wheels are equipped with a spindle for stepless height adjustment. n addition, pendular support wheels can be selected, which allow steering movements.

End tow kit

For safe transport width less than 3 m.
