6.6. Use of top link
IMPORTANT: When using a top link turn the
bracket towards the tractor until it is fully touching
the top link. Then there is no danger that the
bracket fouls the holder pin and damages the
hydraulic top link.
1) If the hydraulic lift cannot raise the implement,
this may be due to incorrect position of the top
link.
NOTE: The lifting force and lifting height are
dependant on which hole the top link is connected
to in the brackets on the tractor and on the
implement.
Maximum lifting height (and minimum lifting force) =
top link in lower attaching hole on tractor and in
upper attaching hole on implement.
Maximum lifting force (and minimum lifting height) =
top link in upper attaching hole on tractor and in
lower attaching hole on implement.
When you are using a hydraulic top link, ensure that
it operates normally when you are attaching an
implement.
2) The hydraulic lift has a greater lifting force when
the top link is moved upwards on the tractor and
downwards on the implement.
3) Top link set too long giving poor lifting height on
rear end of the implement.
4) Lifting height large at rear end since top link has
been lowered on the tractor and raised on the
implement.
5) Draft control does not function since top link
comes too low on the tractor. The wheels spin.
6) The plough does not sink to the required depth
(the top link must be adjusted horizontally). If the
top link is shortened in order to further the plough’s
depth into the ground, care must be taken to hold
the plough straight.
When ploughing, it is important that the plough’s
body is in the same direction with the ground
surface both length ways and sideways. If you alter
ploughing depth, the top link length and the lift link
gear must be readjusted. As a basic rule, the top
link’s end situated towards the plough is set clearly
higher than the end situated towards the tractor.
WARNING: Mounted machinery must be
lowered on the ground before leaving the
tractor
NOTE: See also manufacture’s
instructions.
