Operation and adjustment
Start working with the roller by making the first trial passage. During this task, check
roller adjustment and manner of operation.
If necessary, adjust the length of the tractor
fastener so that the roller frame is positioned horizontally. The working depth of the knife
roller is adjusted by means of the turnbuckles (Fig. 8). The
knives
should operate on the
field surface. The knife roller shall not penetrate into the soil deeper than 2
-
3 cm.
The
working speed on the field with the roller attached should not exceed 15 km/h. A correctly
hitched and adjusted roller should evenly travel before or behind the tractor and evenly
shred the post
-
harvest residue at its entire working width.
