DISC COULTER KITSET
The Disc Coulters are designed to help cut trash/residue or stubble that may be
present in the field. This trash/residue or stubble is cut into short lengths by the Disc
Coulters, allowing the trash/residue or stubble to flow more efficiently past the Seed
Openers resulting in fewer blockages. The Disc Coulters will also help prevent
surface tearing in existing pastures when under sowing.
Setting up the Disc Coulter Kit
If your Seedmatic drill has a Disc Coulter Kit, it is important that this is adjusted
correctly to get the best performance from your drill.
The Disc Coulters are usually set to the same depth as the Seed Openers or slightly
shallower depending on ground conditions. To adjust the depth of the Disc Coulters
turn the Ratchet Link attached between the disc coulter bar and the Headstock frame.
In very hard ground conditions the Disc Coulters may hold-up the drill preventing the
Seed Openers being at the correct depth, if this occurs reduce the depth of the Disc
Coulters.
In very soft/damp ground the Disc Coulters may roll up a strip of turf, if
this occurs reduce the depth of the Disc Coulters.
Tine Alignment
To get the best from your Disc Coulter kit check that the Seed Openers are tracking
behind the Disc Openers. Failure to do so could result in severe tearing of your
pasture. To make these adjustments loosen the top Tine Clamp and slide the Tine
along the mainframe tool bar until alignment is achieved.
