It allows the user to check the seed meter’s performance during planting. A possibility for skips and doubled is greatly eliminated with the correct choice of seed disc and disc runner and the inspection window makes it possible for the user to double-check whether the right choice was made. There should be no skips or double seeds in the seed disc as it rotates over the drop out hole. This and the proper exit of the seed from the seed disc can easily be observed through the window.
Three polyurethane ORGANIZERS ( see 1, 2 & 3 ) are positioned at different angles against the running direction of the seed disc ( red arrow ). These ORGANIZERS wipe the seeds gently into the seed disc ensuring each hole in the seed disc is filled with only one seed at a time. The flexibility of the ORGANIZERS prevent seed from being damaged during the organising process.
