Bottom Flaps (Fig 19)
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 (Fig 19).
The metering system should be checked every half
year or before any sowing period with an empty seed
box and empty metering housings.
Use the following proceedure:
Put the bottom flap setting levers (Fig 20/1) (located on the
LH end of the seed boxes) in position ‘1’.
By turning the metering wheel shaft by hand check the
flaps are all set to a gap of 0.1 to 0.5mm (refer Fig 19).
To adjust individual flaps use the spring tensioning screw
(Fig 20/5).
Storage
Preparing the Machine for Storage.
Locate a dry level surface. Refer also to host machine manual.
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
coulters and allow to hang without deformation. Check tube
lengths when replacing.
