Shutters
Shutters (24/A) have 2 functions:
- Closing / Opening the hopper outlet
- Setting the seed stock height in the sowing roller for
overseeding.
Shutters are not designed to regulate the seed rate!
An incorrect shutter setting can result in variations in seed rates
when sowing on a slope.
Shutter Settings for Undersowing:
The shutter must always be fully opened (
24/2
).
Shutter closed = position 1 (
24/1
)
Do not use intermediary settings.
Shutter Settings for Overseeding:
(Additional accessory.)
Here the shutters on the sowing roller are used to set the seed
level.
This shutter setting depends on how well the seed stock flows. This
may be determined by a seed test. (See also page 2 of the Seed
Chart)
Seed Test for Overseeding
Preparations for seed test:
- Close shutter
- Fill hopper with seed (rape seed)
- Put emptying trays in place
- Secure shutter in position
a
- Gate remains in position 0
- Turn the sowing shaft for at least 10 rotations
Seed test procedure:
Catch the seed from one or more spouts while continuing to turn the
hand crank until the sowing shaft has made exactly one rotation.
The shutter setting is correct
(Fig. 25)
when
36 +/- 4
seeds are
released during one rotation of the sowing shaft.
The seed is not suitable for overseeding if more than
40
seeds are
released per rotation of the sowing shaft with the shutter in the
position
a
.
If fewer than
32
seeds are counted per rotation, secure the shutters
in the next highest position (first „
b
“,
then „
c
“ or „
d
“). (
Fig. 25
)
The seed test must be repeated each time.
- Important Note:
- After each change of shutter position, turn the sowing shaft for
at least 10 rotations!
- The seed test should also be performed during
operation to ensure proper overseeding.
Clogged cups may sometimes cause a decrease in
seed rate. Clean cups with a brush!
