Pneumatic seed drills MISTRAL are designed for sowing cereals (wheat, barley, rye, oat), leguminous, oil plants (pea, bean, soya bean, rape) and grass with seed sizes ranging from 1 mm to 10 mm.
Centralised seed metering is the heart of the whole system. It maximises the precision of drilling process. A precise volume of seed is metered by metering wheel (2). The volume metered is regulated with the shroud (2a) and continuously cleaned with the nylon brush (2b). Metering precision does not depend on variation in seed, slope of a field or vibration. The profile of the metering wheel eliminates inaccuracy and blockages. The tank can be quickly and easily emptied by the central fast emptyin flap. Fine seeds can be drilled nearly completely out with only a small amount of seed left in the botton of the hopper (half a kilogram for maximum). The contents of the metering device should always be cleaned out thoroughly to prevent inaccuracy especially when drilling fine seeds or prevent rodent damage when the dril lis left standing for long periods.
