The HEADLAND spreading system, FROM BORDER, is developed
for considering the environment as much as possible – and
considering at the same time the demands for optimum yield.
• Please consider that the distance between the tramlines must be equal to the
spread width.
• If first tramline is placed 1 metre from border – the distance from border
to next tramline must be equal to the spread width + 1 metre.
See the above pattern: First tramline = 1 metre from border.
Second tramline = (18 + 1) = 19 metres from border.
REDUCED SPREAD WIDTH
In case it is necessary to reduce the spread width, for instance when spreading on
a narrower final bout in the field, or in connection with non rectangular parts in the
field – the spread width can be limited by either tilting the spreader negatively or by
reducing the PTO- rpms.
REDUCED PTO- speed:
• When reducing by 75 rpm. the NORMAL spread width is reduced by 2 metres.
• At the same time the quantity must be reduced to the relation between the
NORMAL spread widht and the REDUCED spread width.
• The reduction of quantity can be adjusted by increasing the driving speed
respectively, if this is easier.

Reduction
12 metres 10 metres (540 – 75) = 465 (12/10) x 10,0 = 12,0 - 17 %
15 metres 13 metres (540 – 75) = 465 (15/13) x 10,0 = 11,5 - 13 %
18 metres 16 metres (540 – 75) = 465 (18/16) x 10,0 = 11,3 - 11 %
18 metres 14 metres (540 – 150) = 390 (18/14) x 10,0 = 12,9 - 22 %
REDUCED TILT- angle:
• If the tractor is equipped with hydraulic top link a reduction of the tilt-angle of
-2° will reduce the NORMAL spread width with 2 metres.
• At the same time the quantity must be reduced according to the above
instruction.
