Advice on sowing
72 Ver.07/06/01 07/06/01
4.5 Tramlining
The tramline options possible and the settings on the Control Box are described in ”3.16.3 Pro-
gramming the Type III Control Box” on page 54 and ”3.16.8 Tramline options” on page 62.
During sowing, the most important thing to remember about tramlining is to shut off Autostep
before doing anything other than normal sowing or turning in headlands between bouts.
So, remember to switch Autostep off before raising the drill to pass an obstruction.
When stopping to re-fill the hopper or for a rest period, raise the drill out of the last bout and wait
10 seconds. Then turn off Autostep. Autostep does not have to be turned off, however, if no other
lifting is to be done during the rest period. Move the switch back to Autostep before the drill is
raised for the first time once work is resumed.
4.6 Bout markers
The Control Box setting for the markers are described in ”3.16.4 Settings and functions” on page
58. See also ”4.7 Obstructions” on page 72 and ”4.8 Turning with Low lift” on page 72.
Once a reliable setting for the bout markers has been found, it is a good idea to mark this position
using e.g. a centre punch. Check occasionally that the marker tines are securely tightened.
The final tillage operation before sowing should preferably not be done in exactly the same direc-
tion as that intended for sowing, but at a slight angle to it.
4.7 Obstructions
Switch off Autostep, see “Figure 3.43” point 16, before the drill is raised to sow around a post,
well or other obstacle.
NOTE!
When the drill is raised to clear an obstruction during a bout, the drive wheel will also be
raised, which stops the seed feed. This can occur even with very slight raising of the drill.
During sowing, the bout markers can be retracted to avoid an obstruction by moving the Lift stop
switch, see “Figure 3.43” point 17, to the down position and moving the hydraulic lever to lift po-
sition. The markers will now fold in while the drill remains in work. Extend the markers again. In
this case, neither Autostep nor the multiple selector for the markers needs to be moved.
4.8 Turning with Low lift
When the drill is lifted out of work at the headland, the drive wheel is raised and the bout marker
is retracted. If Low lift is activated, the drill will be raised to Low lift height.
When the drill is raised at the headland the bout markers and tramlining sequence is automatically
advanced one position. If the drill will not lift, Lift stop is probably switched on, with the switch
in the down position. If the markers and tramlining do not advance automatically, Autostep is pro-
bably switched off.
When turning in Low lift, the following harrow remains in work during the entire turn.
NOTE!
Before reversing the machine, Low lift must be switched off and the drill raised to the full
lift position.
