If the roll 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 Simba 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.
4. Adjustment / Operation
4.6 Using Shims
Before using shims to alter machine settings
ensure the machine is stationary and the
tractor is turned off with the keys out. Ensure
that all operators are clear of the machine
and that no load is being held on any existing
shims in the cylinder / depth control rod.
To fit the shims hold them by the handle and,
using a firm action, clip them onto the rod
as shown in Fig. 4.05. They are removed by
using a finger to pull firmly on the handle.
Check the cylinder / depth control
rod for damage and debris before
fitting shims.
Only attempt to add or remove
shims using the handle. Trying to
manipulate shims using the jaws
could result in injury.
When changing machine settings
ensure both sides of the machine
mirror each other. The left hand
cylinder should contain the same
amount of shims as the right, for
example. Failure to do this could
result in damage to the machine.
