Note: These charts are relating to “standard” seed size and shape. Some seeds, such as peas and beans, tend to vary
in size that it is recommended to make calibration tests with care to adjust the required seed rate. Flap position must
be adjusted depending on size and shape.
Note: For variator settings of 0-60 the recommended drill speed is 8-9 mph. For variator settings 60-90 the recommend-
ed drill speed is 5-6 mph.
