10.3 Straw harrow STR 80
The straw harrow (H) will be fitted between the following roller and the hollow
discs (18) and to the lower carrier (T).
By means of the pin (ST) the straw harrow can be adjusted either in working
depth as well as in the distance to the hollow discs (18).
By means of the pins (S2) the angle of the harrow to the soil will be adjusted. The
pin (S1) prevents a swinging back of the straw harrow in lifted position.
For work the straw harrow must be adjusted, so that the straw will be distributed
very well, but not pile up.
It must be ensured, that the tines (Z) of the straw harrow do not touch the
following roller.
The steeper the harrow tines (Z) are positioned, the better is the crumbling.
The less steep the harrow tines (Z) are positioned, the less is the danger of
clogging.
Straw, which will be taken along by the harrow tines, can be taken out by the
rollers again. Therewith the danger of clogging will be minimised.
