Marker Setup
The V300 and V300F may have optional dual folding
pass markers and dual pre-emergence/tramline markers.
Dual Marker Setup
Although dual markers may have been dealer-installed,
they may not be set to ideal extension length or optimal
operating speed. Check these items before first use.
If there is any question about the state of the marker
hydraulics, see also “Bleeding Marker Hydraulics” on
page 100.
Mark width and throw direction are adjustable.
Dual Marker Extension
Refer to Figure 22
1.
Extend the marker on one side.
2. Lower the drill, and pull forward a meter or so to
leave a mark with both the coulters and the marker.
3. Measure the distance from the mark left by the
outside coulter to the mark left by the marker. Mea-
sure parallel to the hitch tool bars.
For the V300 and V300F in normal configuration (all
row units in use), distance
is:
158 cm or 62.2in ( 1 ⁄
2
swath + 1 ⁄
2
row space).
You can also measure from drill centerline to the
marker, in which case use:
3.00 m or 118.2in
4. If the marker extension needs to be adjusted, first
make sure that the mark is satisfactory, as changing
the disk angle or direction changes marker exten-
sion. See “Dual Marker Disk Setup” on page 26.
Refer to Figure 23
!
CAUTION
Be careful working around marker disks. The blades are often
sharp.
5. Loosen the two nuts securing the U-bolt secur-
ing the marker tube extension in the outer marker
arm tube .
6. Slide the marker tube extension in or out as
needed, and secure nuts.
