Centaya Special harrow-mounted seed drill

The centre of gravity of the seed hopper of the Centaya Special is close to the tractor and ensures comfortable working conditions. The 1,000 litre hopper capacity can be expanded to 1,500 litres using an extension to ensure that the tank size is adequate. The hopper is made of metal and is easily accessible via the ladder and loading board. The deep hopper tip and steep hopper walls reliably guide the seed down to the metering unit to leave minimal residual quantities.

The advantages of the Centaya Special hopper:

• Large seed hopper with spacious hopper opening
• Optimum machine centre of gravity
• Good accessibility

The seed hopper can be filled effortlessly from a big bag, front loader bucket or sacks through the large 2.30 x 0.84 m filling opening. 

The loading board with handrail and ladder makes it easy to fill the seed hopper from sacks. The sieves of the seed hopper can be used to put the sacks down on.

The fill level can be comfortably monitored on the machine terminal via an adjustable fill level sensor. An optional low level sensor can be fitted in the metering unit housing to indicate when the hopper is empty.

The dual chamber hopper on the Centaya-C Special offers the option of sowing companion crops and undersown crops in addition to the main cash crop. These are of great benefit for weed control and for increasing erosion control and biodiversity. In addition, the simultaneous application of fertiliser is an efficient solution that leads to rapid seedling development and high field emergence.

Accurate metering

On the Centaya Special or Centaya-C Special, a wide variety of applied materials can be metered accurately via the infinitely adjustable electric metering units with seed rates from 0.5 to 400 kg/ha.

The hopper capacity of the Centaya-C Special of 1,500 l is divided in the ratio of 70: 30. Two different materials can be filled in volumes of 1,050 and 450 l. The conveying system feeds the different materials to the coulters via the segmented distributor head. Here, materials are applied to a delivery point in the soil using the Single-Shoot method. The two metering units mean that different seed rates can be simultaneously metered using the appropriate metering rollers.

The Micro plus micro-granular applicator can be used to place even small quantities of micro-fertiliser directly alongside the seed during sowing. The micro-granular applicator meters the fertiliser into the seed tube of the drill. The fertiliser is thereby delivered to the seed row via the conveying system together with the seed using the Single-Shoot process.

Micro plus is equipped with a central electric metering system under the easily accessible 110 l hopper. The filling opening with a diameter of 195 mm enables quick and easy filling. The micro-granular applicator is controlled via the ISOBUS software of the seed drill.
 

Also the combination of the Micro plus micro-granular applicator allows the driver to apply a third material in the seed furrow in a single pass. The application utilises small quantities of micronutrients or low seed rates, for example, which are sown into the same seed tube as the other applied materials.

Single-Shoot - the simultaneous application of more than one seed type or fertiliser at the same entry point in the soil – can be a powerful tool for yield-guaranteeing, future-oriented arable farming.

Advantages of the Single-Shoot method for applying different seeds:
No de-mixing for ideal plant distribution of the various crops in just one pass
