OPTILINE<br />
UNIDISC version : even<br />
better suited to simplfied drilling<br />
For drilling onto plant trash<br />
■ Better flow of long trash thanks to the wide clearance<br />
between rows ( >300 mm)<br />
■ Total vertical clearance : better flow of soil and better<br />
anti-bounce effect from the springs placed overhead<br />
(protected against blockages from soil or trash)<br />
■ A large diameter disc (300 mm), to easily get through<br />
plant trash and firmly open a furrow even with deep<br />
drilling.<br />
Anti-blockage<br />
downspout<br />
“Double effect” spring fitted<br />
over the drilling element arm<br />
Extra-strong sowing arm<br />
with Ø 43 mm angled tube<br />
Seed placement worthy<br />
of a Suffolk coulter<br />
■ The combination of a curved disc/castiron<br />
coulter forms a V in the soil<br />
similar to that of a Suffolk coulter, it<br />
improves depth control and enables<br />
the seed to be placed at the required<br />
depth<br />
■ The attacking angle (5,5°) ensures<br />
excellent disc rotation, even on<br />
loose soils<br />
New coulter with<br />
integrated depth<br />
control :<br />
it also guarantees the<br />
inside of the disc is<br />
kept clean<br />
