When tramlining the number on both sides of the colon is the same. In addition, the
controller indicates that tramlining has started by giving an audible signal. Also, the
wheel track value will flash five time. When the machine is next lifted, the counter
will be reset to 1 and the symbol will stop blinking. After the next lifts, the first value
will indicate the current rhythm position and the second the tramlining rhythm. (E.g.
For example, 2/3 indicates that the current tramlining rhythm position is 2 and that a
tramline will be created after every third lift. These kinds of settings are used when
the width of the seeder is 4 m and the spraying width is 12 m.
Every lift of the machine increases the counter value by one. In order to avoid such
unintended increase of the counter value which is caused by the machine rocking
strongly, for example, the system has a delay-time feature which ensures that the
counter value will not be increased by successive impulses during the delay time.
When seeding a whole field, for example, it is necessary that the counter value in the
counter of the tramlining device does not increase with every lift of the machine, such
as at field corners. Neither should the counter value increase due to obstructions, such
as big rocks, which may make it necessary to lift the machine during driving. If you
have to raise the machine in this kind of situation, you can either let the tramline
change when the machine is raised and correct it manually later, or, before raising the
machine, you can press and hold the Stop/OK key for more than 4 seconds, which
puts the system into stop mode, meaning that the marker changer will not react even
though the seeder is being raised and lowered.
Remember to exit stop mode immediately after an additional lift or, when seeding
the whole field, after the whole round.
If you want to start tramlining, the counter value must be set to match the tramlining
rhythm value (for example 5/5). A blinking tramlining number indicates that
tramlining mode has been turned on. To indicate that tramlining mode is being
activated, the system sounds five beeps.

Down-pressure (only in Tume Nova models)
In Tume Nova models, coulter down-pressure is transferred to the coulters when the
seed fertilizer’s container section is lowered. When this happens, the springs between
the coulter bars of coulter carriers will push the coulter carriers towards the ground.
The lower the container is lowered, the higher the down-pressure. Agrocont stops the
lowering at a set height. This height limit can be adjusted by changing settings. The
down-pressure can be adjusted from 0-15: 0 is the lowest down-pressure, meaning
that the middle part of the seed fertilizer will remain relatively high when the
container part of the seed fertilizer is lowered, and 15 is the highest down-pressure,
meaning that the container will be relatively low.
Selecting the maximum down-pressure
When you press the down-pressure key (key 6, shown in Figure 9), the green light
above the key and the amount of down-pressure (e.g. P=11) will start blinking on the
screen. You can change the down-pressure by pressing the plus and minus keys. The
mode where the light and the down-pressure value blink will be turned off after 5
seconds if the value is not changed before that by using the plus and minus keys or if
the value on the screen is not accepted with the Stop/OK key.
