6.6 Adjustment
of
the
multi-disc spreading discs
6.6.1 Principle of operation
The disc vanes on the spreading discs can be adjusted to accept various types
of fertiliser, different fertiliser operations, as well as different working widths.
Different spreading operation mode possibilities are :
1.
Normal spreading.
2.
Border spreading either to the left- or right-hand side when in the normal
spreading mode.
3.
Late season top dressing.
4.
Border spreading either to the left- or right-hand side when in the late sea-
son top dressing mode.
•
Each disc is equipped with two identical disc vanes.
•
Each vane consists of a main vane with an extension vane.
•
The main vane of the
right-hand
spreading disc is identified with the letters
BR and its corresponding extension vane with the letters AR.
•
The main vane of the
left-hand
spreading disc is identified with the letters
BL and its corresponding extension vane with the letters AL.
•
Each vane angle can be increased or decreased. Also, the vane's effective
length can be shortened or increased.
Decreasing the vane angle means that the vane is moved from higher to lower
numbers. The numbers are stamped into the discs.
Increasing the vane angle means that the vane is moved from lower to higher
numbers. The numbers are stamped into the discs.
Shortening the vane length means that the slidable vane extension is moved
towards the disc centre and locked in place.
Increasing the vane length means that the slidable vane extension is moved
away from the disc centre and locked in place.
