Cracker Disk roller
Field of application
The CDW cracker disc roller is used on medium
to heavy soils.
Method
The steel packer rings of the cracker disc roller
(Fig. 34/1) consolidate the soil in strips. In
combination with a seed drill, the seed is
embedded in the compacted soil. The integrated
cross bars of the steel packer rings provide
additional traction for the roller. The cracker disc
roller has a spring-suspended cutting rail (Fig.
34/2).
Fig. 34
Two adjustment segments (Fig. 35/3) with
integrated springs (Fig. 35/4) are used to adjust
the cutting rail. During operation, the blades can
avoid obstacles in the soil by deflecting upwards.
Upon delivery, the cutting rail is adjusted such
that the ends of the blades are flush with the
edges of the roller.
