Sowing Fine Seeds
For sowing fine seeds the Vineyard Seeder is equipped as
standard with a combined normal and fine seed “Elite” metering
wheel (1). During grain sowing and other larger varieties of seed
both the normal and fine seed metering wheels are coupled and
both rotate. In order to convert the seed drill to sow fine seed insert
the crank handle and rotate clockwise until the holes (2) of the fine
seed wheel are visible (Fig 10).
Using the tool supplied (Fig 11/1) disengage the the pin inside
the hole so that the normal metering wheel rotates freely on
the metering shaft.
At this time it would be advisable to close any shutter slides
not required for the fine seed sowing.
When seed is to be sown again using the normal metering wheel
press the pin, from the normal metering wheel side (opposite
direction to before), using the tool, back into the hole of the fine
seed wheel thus reconnecting the drive between the two.
