Rape brushes
The rape brushes clean the metering discs in
the roller for sowing small seeds.
Prior to sowing small seed, the rape brushes
must be installed in the rear cover and tested
for correct operation.
Rape brushes fitted
Check for true running and correct securing.
Check the condition and cleaning efficiency
of the brushes.
Fit the side cover with brushes into the meter-
ing unit.
The brushes must make good contact with the
metering wheels and rotate with the roller.
The rape brushes must be checked for
function and cleaning efficiency prior
to commencing sowing and then at
regular intervals.
Clogged metering wheels cause metering errors
when sowing. Fewer seeds are distributed.
The side cover with the rape brushes can also
be removed when the seed hopper is full.
At the same time, clogged metering discs can
be cleaned in situ.
The rape brushes should be removed when
sowing normal-size seed. The bolt holes must
be closed again.
Large seed
In the case of large seed (maize, beans, peas,
etc.), a deflector is installed instead of the rape
brushes.
This deflector prevents large seeds from becom-
ing jammed and ground up between the roller
and the housing and from blocking the roller.
Deflector
A high partition plate is installed in some meter-
ing units.
This plate must be cut off at the lower edge of
the inspection window to enable the scraper to
be installed.
