Activating and adjusting the height of RowDisc hoe protection discs

If you want to use the RowDisc hoe protection discs for a hoeing pass, the RowDisc hoe protection discs must be moved from the passive position A to the active position B and their height must be adjusted.

The height adjustment depends on the design of the hoe protection discs:

For RowDisc SR hoe protection discs with serrated discs and RowDisc RD hoe protection discs with smooth discs, the adjustment of the height depends on the growth stage and size of the crops at the time of the hoeing pass:

  • For younger or small crops, the hoe protection discs should have contact with and be driven by the ground during hoeing operation. During activation, the hoe protection disc is lowered onto the ground. Afterwards, no more adjustments are made to the height.

  • For older or large crops, the hoe protection discs should have contact with and be driven by the leaves of the crops during hoeing operation. After activation, the hoe protection discs must be positioned higher relative to the leaves.

The RowDisc SD hoe protection discs with concave discs should always have contact with and be driven by the ground during hoeing operation. During activation, the hoe protection disc is lowered onto the ground. Afterwards, no more adjustments are made to the height.

CAUTION
Risk of injury due to falling hoe protection disc
Hold onto the hoe protection disc tightly when activating, adjusting and deactivating.
  1. Lower the implement on the field with the three-point power lift.
  1. Grab the RowDisc hoe protection disc 2 by the holder 3 and pull the bar 1 to the rear.

  1. If the RowDisc hoe protection discs should follow the ground contours at a greater depth that the linch pin allows in the rearmost position:

    Pull out the linch pin 1 on the activated RowDisc hoe protection disc and park it in the holes 2.

  1. If the SR and RD type RowDisc hoe protection discs should be used on older or large crops:

    Follow steps 7 to 9.
  2. Pull out the linch pin 1 on the activated RowDisc hoe protection disc.
  3. Lift the RowDisc hoe protection disc 4 to the desired height.
  4. Insert the linch pin through the holes 3 directly behind the retaining lug 2.
  5. Activate and adjust the height of the RowDisc hoe protection discs on all of the parallelograms in the same way.
