The working width for each body is chan-
ged using wedges (1) that are screwed
between the leg (2) and the frog (3). Three
working widths are possible for each body.
Narrow side of the wedge (1) points for-
wards
=> less working width for each body
Without wedges
=> medium working width for each body
Wide side of the wedge (1) points for-
wards
=> more working width for each body
The tail pieces (2) being positioned at the
end of the mouldboards (1) help to turn the
furrow slice.
Adjust all tail pieces uniformly.
Set too deeply, they can cause soil to fall
back into the furrow.
