2.8 Heights and Levelling
All frame sections must be at the correct
height and level to maintain even planting
depth. The hitch height sets the mainframe
level, and must be at a consistent height
to both maintain level, and maintain radar
speed calibration.
Periodic frame-levelling adjustments
should not be necessary. If you are having
problems with uneven depth, level drill if
necessary.
To ensure consistent seeding depth the
frame should be set level while planting.
Failure to do so may result in implement
not producing desired results.
2.9 Checking Drill Height
The implement frame should be level with
the ground during planting, this will allow
the row units to operate at their most
consistent planting depth.
Your crop, soil conditions, disc wear and
other factors may create a need to use a
different toolbar height.
Cultivation disc and levelling board height
is controlled hydraulically ahead of the
tyre packer. On machines fitted with the
weigh cell option, wing weight transfer is
controlled automatically. The pressure can
be monitored using the upper gauge at the
front of the machine.
When checking toolbar height:
1. Move the drill to representative planting
soil conditions.
2. Set linkage height.
3. Lower and unfold the implement (page
26).
4. Pull forward 10 metres or so to put
openers in the ground.
5. Check toolbar height across drill.
2.9.1 Boutmarker Setup
Prior to first use the marker extension
should be set or reviewed. See “Boutmarker
Adjustments” on page 38.
Prior to each planting session, check and
adjust “Boutmarker Disc Adjustment” on
page 39.
