5.3 Test folding of the grassland harrow (with hydraulic folding)
Couple the hydraulic line plugs (ensure that they are always kept clean). Fill the
cylinder with oil. The cylinder is filled as soon as the safety chains are relieved. Unhook
the safety chains and hook onto the other end of the chain. Ensure that no one is
standing in the danger area and that you only fold the implement when it is lifted from
the ground. When folding into transport position, the implement must also be lifted from
the ground. Do not forget to hook on the safety chains or to close the stop tap.
6 Working position and setting the working depth
The height-adjustable levelling plate removes coarse unevenness in the grassland and
spares the tines unnecessary strain.
Due to the narrow line distances of these individual tines (75 mm for 10/12 mm tines
and 50 mm for 8 mm tines), the sward is optimally prepared and the plants can
germinate rapidly after reseeding.
The two front tine rows tear up the sward. The rear tine rows produce an optimal
seedbed for the new grasses.
If the rear tines should work more
aggressively, you can choose one of four
levels. At an optimal forward speed, the
tines make an elliptical motion. The
steeper the position of the tines, the
smaller the motion. The flatter the position
of the tines, the larger the motion. If the
sward is dense and intense tillage is
required, the tines should be positioned
more steeply (see Fig.: 2).
The front and rear tine rows should
penetrate the soil to the same depth
(working depth).
If the 10/12 mm tines should work more intensively, position the feeler wheels higher
up.
If the 8 mm tines should work more intensively, extend the top link.
The tine aggressiveness is set using an adjustment lever. One adjustment lever per
row and array (Fig.: 2). Depending on the soil type, more load can be applied to the
tines through the array and the frame.
