The correct adjustment of the discs leaves the field level with no visible traces of the
harrow tines. Fine adjustment of the discs is done with the spindle (A) and not until
actually in the field. Discs must be adjusted to work the topsoil, so that a suitable
quantity of earth is thrown back after the harrow tine.

The angle of the tine
Adjusting the penetration angle in two different positions (A, B) makes it possible to
have a soil-searching tine all the time.
Fig. 3
On dry and hard soil use the most soil-searching/aggressive adjustment (A, fig. 3). On
light and moist soil use the front hole (B). Due to wear and tractive force the
penetration angle should not be larger than necessary to obtain a satisfactory
outcome.

The safety bolt (A) must be a
16x80 4.6, because it must break
if the tine is overloaded.
