23 Flatliner 500
Operating Instructions
If the crumbler is exerting too much pressure
for the conditions, but if raised will cause the
machine to operate too deeply, then draft
control may have to be used. The operating
depth can be controlled to a certain extent by
lengthening the tractor top link. This causes
the implement to run tail down and reduces
the downward thrust on the points and wings,
reducing the shattering effect of the tines.
The lowest draught requirement is achieved
when the machine is slightly tail down (all points
touching the ground at the same time).
However the best shattering effect is
achieved when the main frame is running level,
this attitude being more desirable.
Hard/Dry Conditions
The Flatliner 500 achieves best results in dry
conditions but under very hard/dry conditions
it may produce large clods of soil at the
surface. If the roll unit is unable to break these
clods down effectively this may be overcome
by removing the tines and increasing the
spacing, or an initial precultivation at 50 to
100mm (eg. Disc) depth to eliminate the
possibility of forming large clods from soil at
this depth.
Surface Trash
The ‘ V ‘ shape of the Flatliner frame is ideal
for fields with surface trash as there are few
places for blockages to occur, but under
extreme conditions fouling may still be
evident. This can be overcome by either
increasing the mainframe to ground
clearance of the implement (by lowering the
tines in their clamps) or by removing some
tines if necessary.
