A DRUM SEEDER THAT HAS GALLERIES ALONG ITS LENGTH WHICH CONNECT TO A VACUUM AND PRESSURE SOURCES. VACUUM IS APPLIED TO THE HOLES, WHICH PICKS UP THE SEEDS AND CARRIES THEM UNDER TWO AIR CURTAINS TO REMOVE MULTIPLE PICK UPS. THE SEEDS ARE THEN CARRIED ROUND TO THE DISCHARGE POSITION WHERE THE VACUUM IS REPLACED BY LOW PRESSURE AIR TO DISCHARGE THE SEEDS ACCURATELY INTO THE TRAY. FOLLOWING DISCHARGE, A HIGH PRESSURE AIR BLAST CLEANS THE HOLES BEFORE THE CYCLE REPEATS. THE DRUM IS DRIVEN BY A HYBRID STEPPER MOTOR, LINKED ELECTRONICALLY TO A SPEED PICK UP ON THE CONVEYOR. AS THE TRAY PASSES UNDER THE SEEDER IT BREAKS AN INFRA-RED BEAM, WHICH STARTS THE DRUM ROTATING IN PERFECT TIMING WITH THE CONVEYOR BELT.
