Caution! Before starting sowing, the relative position of coulters and harrow tines to each
other must be ensured with a tow test. This can be carried out in a field or in soft sand. Each
fertilizer coulter must always travel at a distance half-way between two seed coulters under
direct tow. The gap between seed coulters must be approximately 125 mm, and the harrow
tines must travel between the seed rows. Move the coulters and tines laterally as required.
This check must be performed at least once per usage period.
Driving instructions
Driving instructions for transport
The machine is kept in its upper position by means of the tractor hydraulic valve. For this reason, it must be
ensured during any transport that there are no leaks in the tractor hydraulics, and that the hydraulic lever
controlling the raising or lowering of the machine is not moved accidentally.
Keep the lift cylinder safety
taps open during transport as well as during sowing, see Fig. 39.
During transport, the maximum permissible speed is 30 km/h. See general safety instructions, Section 2.
Driving instructions for sowing work
If the ground wheel is in its raised position with the transport support (Fig. 5), lower it to its usage position,
see Fig. 14.
Caution! Always move forward when lowering the machine. Otherwise the coulter arms
may become damaged or the coulters may become clogged.
Avoid unnecessary driving in the sown area. Select a driving technique that ensures that only minimal tire
tracks are left in the sown area. It is usually good to start seeding on the basis of a single block, so that
sufficiently wide tracks can be generated (usually 1-2 times the width of protective plant spraying). Sowing
is then performed back and forth, driving in the direction of the longest side of the block.
Caution! Try wherever possible not to sow the corners of the block in a circular motion,
and raise the machine at corners. Making steep turns with the machine and coulters
on the ground will cause unnecessary wear to the machine tow-bar and coulters!
All-around sowing is used on irregular blocks. Lift the machine at all corners! Only sow in a gentle circle in
the ground on clearly wide corners!
Because of the hydraulic structures, the machine must always be lifted all the way to its upper position. Only
then can the machine be lowered again. Conversely, when lowering the machine, the lower position must
be reached before the machine can be raised again. When sowing, care must be taken not to lift the machine,
as it cannot be lowered back to its correct working depth unless it is first raised high enough that the depth
control valve (Fig. 31) is reopened.
Fig. 31 shows the valve controlling raising and lowering, moving with the wheel support arm. When the valve
lever reaches the up and down positions of the guiding pins, the valve closes and the lifting or lowering
motion is stopped.
Ensure that the harrow is raised sufficiently when lifting the machine. See Section 16, adjusting the harrow.
Caution! Never reverse when the harrow tines are in contact the ground. Similarly, do
not reverse into contact with the earth formation at a field edge or other obstacles.
The machine must be able to work on even terrain in a horizontal position. See Section 14, fertilizer
application depth adjustment. If the machine is angled forward as it moves (this can happen if towed in any
other way than with the tow-triangle) the towing device push-bar must be extended. If the machine is angled
backwards as it moved, the push-bar must be shortened.
Note the push-bar adjustment area! Check the
