COULTEr ExCHAngEr
Coulter Exchanger
In the case of the „Vitasem, Aerosem", the shoe and broad-shoe
coulters may be exchanged without tools.
Unhook the spring (
61/1
) and pull the spring-secured pin (
61/2
).
Re-secure the pin after mounting.
Shoe Coulter (Fig. 61) – Normal 0
For shallow seed placement, adjustable depth limiters may be attached
to the shoe coulters at any time (
61/4
).
Broad-Shoe Coulter (Fig. 62) – Approx. 8,5 cm wide
For wide, yield-increasing seed spread; suitable for clean soils with
fine tilth.
Shoe and broad-shoe coulters have a clogging-protection support;
fold forwards elastically to avoid bending while lowering.
Single-Disc Coulter (Fig. 63)
Ideal for crop residue with long stalks.
The rotating scraper (
63/1
) cleans sticky soil off the inner side of the
clearing disc (
63/2
). The curved outer side cleans itself.
The rubber skirt (
63/3
) prevents the seed from jumping out of the
furrow.
The pressure of the rotating scraper may be adjusted by screwing
the threaded axle (
63/4
) in or out. Secure the threaded axle with
lock nut.
Ensure that the PVC disc of the rotating scraper does
not connect in front, as this would produce a braking
effect on the clearing disc.
Pinch Roller (Fig. 64)
(Additional equipment)
Press roller on the seed drill
• Seeds in the drill are pressed lightly into the ground
Press roller near the seed drill
Only for machines with at least a 14 cm gap between rows
• Seed drill is pressed shut by roller
With that roller (64/1) can be screwed again to its holder (64/2)
Depth setting of single-disc coulters
Single-disc coulters are guided deep by press roller. Depth setting
can be adjusted by inserting spring pin (64/) in 1 cm stages
