REMOVING SCARIFIER SHANKS
Scarifier shanks have four operating positions in
the box blade. They may be removed if scarifying
action is not needed.

x 10 cm) blocks under each side-frame of the box
blade (see Page 11, Figure 4).
2. Lower the box blade to rest securely on the
blocks.
NOTE: Do not block the machine any higher than
necessary to remove the shanks or cutting
edge.
