8.TYPES OF DISTRIBUTION
8.1 SEED DISTRIBUTION BY MECHANICAL FAN
To ensure that seeds are supplied
to the tine coulters' sowing shoes,
it is essential that the fan speed
is between 4200 and 4500 rpm.
For this purpose, the PTO shaft
must be plugged into the 1000
rpm vent.
If the turning speed is lower then
some seeds are likely to remain in
the seed hoses.
Before the wheel controlling the distributor's transmission starts turning,
please ensure that the fan's turning speed is between 4200 and 4500. When
raising the machine, never decrease the fan's turning speed until the wheel
is detached from the ground.
Please note that if you work with the machine while the fan is off, seeds will
block the collecting pipe of the venturi injector sluice. In case this happens,
the collector should be taken out and emptied before using the seed drill
again.
IF THE FAN'S TURNING SPEED IS ABOVE OR BELOW 4200 AND 4500 RPM,
THEN TURNING THE WHEEL THAT CONTROLS THE DISTRIBUTOR'S TRANS-
MISSION CAN CAUSE A BLOCKAGE INSIDE THE SEED HOSES.
