Maintenance & Care (Continued)
9. Bottom Flaps
The required seed rate is controlled by both the metering
wheels and the bottom flaps. The seed flows from the seed
box into the metering wheel housings. Inside the metering
wheel housing (1) the seed is caught between the metering
wheel (2) and the bottom flap (3). The metered amount
of seed is transported by the metering wheel to the edge
of the bottom flap where it drops off into the seed guide
tube which leads to the coulter. Varying grain sizes require
the matching of the flap clearance to the different grain
sizes. This matching is done by raising or lowering the
bottom flaps by using the flap adjusting lever on the LH
end of the seed box. If larger foreign particles, e.g. stones
get between the metering wheel and the bottom flap, the
bottom flap can give way downwards. A strong return
spring (4) brings the bottom flap immediately back into the
working position.
The metering system should be checked every 1/2 year
or before any sowing period with an empty seed box
and empty metering housings.
Use the following procedure:
Put the bottom flap setting levers (6) (located on the LH
end of the seed boxes) in position “1” for the front box and
position “1” for the rear box.
By turning the metering wheel shaft by hand check the
flaps are all set to a gap of 0.1 to 0.5mm.
To adjust individual flaps use the spring tensioning screw
(5) .
Note: Maintenance Schedule (page 30)
Where the frequency is given in terms of use (eg. weekly)
or area covered (eg. 75 Ha) perform the maintenance task
based on whichever occurs first.
Preparing the Machine for Storage.
Locate on a dry level surface. The machine should be
stored wherever possible so the rams are not supporting
any weight. The drive chains should be lubricated with
suitable roller chain lubricant before prolonged periods of
storage.
For longer term storage remove seed/fertiliser tubes
from the boot assembly and allow to hang without
deformation. Check tube lengths when replacing.
It is recommended that maintenance be carried out
at the end of the season, giving sufficient time to
obtain spare parts and/or carry out repairs if required.
