7.1 Tips for correct usage
- Preparing the combined implement for work:
soil preparation tools, running gear, lane mar-
kers, fan speed / hydraulic motor.
- Check settings (as in turning test): Dosing-
wheel setting (coarse-dosing wheel blocked
when using fine seed), agitator shaft (agitator
fingers removed when handling rapeseed),
turning cover, seed-quantity settings,
- Switch on the electronic system.
- When starting up prior to use, run the motor
at half-speed at least, then maintain a constant
turning speed,
- Start sowing operation. Note that seed takes a
certain time to get from the dosing mechanism
to the sowing coulters (approx. 1 s / 2 m). This
should also be taken into account when stop-
ping briefly. Raise the implement and carry out
a reset (see “Pre-dosing”).
- Check all coulters for blockages before star-
ting to sow, and re-examine at regular intervals.
- Check sowing depth
- Match drive speed to working conditions so
that the seed is evenly spread.
- Always leave the hydraulic control device for
the lane markers in “float” mode during opera-
tion (see also “Lane markers”),
- When filling up, ensure that no foreign bodies
(waste paper, sack ties) get into the hopper.
Keep the hopper cover closed during opera-
tion. Monitor the filling level (low-level indica-
tor),
- Given the hygroscopic characteristics of seed
(including dressing agent), the hopper should
be emptied before a long period without opera-
tion. Note that dressing agent is a toxic irritant.
- Emptying the remains: Lower the drilling
machine and place a collection container
under the discharge hopper. After emptying,
turn all dosing wheels slightly (with star grip)
and/or press the button to run the fan briefly to
remove all remains of seed (so as not to attract
rodents and other pests).
7. Checking of sowing accuracy on
drilling machines with elec. dosing
wheel drive.
Rule 1
The electrical turning system and manual
turning system at the tail wheel must always
produce the same turn readings.
(Only slight fluctuations are permitted)
(Only possible on machines with tail wheel)
Rule 2
The electronic Ha counter setting
must match the working width of the
machine.
Rule 3
The turning procedure should only be carried
out without enabling the additional amount.
Rule 4
Select the recommended dosing-wheel setting.
Rule 5
Use calibrated scales (domestic scales). Do
not use a spring balance or sack scales.
The above points must be observed if best-
possible performance is to be guaranteed.
