Metering | Conveying system

Precis – The new conventional metering system

The AMAZONE Precis metering system with integrated hopper inserts ensures minimum residual amounts and even sowing. The seed shaft is driven either mechanically by the land wheel drive or, as an option, electrically via ElectricDrive. Across a wide range of seeds, an outstanding consistency of distribution is ensured. The centralised calibration flap makes for an easy changeover from calibration to drilling.

Thanks to the integrated discharge funnels hardly any residual amounts remain in the seed hopper so that even a change of seed can be carried out quickly and conveniently. The conversion from fine to normal seed is possible via the shutter slide. Even an exchange of the seed wheels is, due to the accessibility of the metering system, possible without any problem.

The adjustable fill level sensor monitors the fill level of the seed hopper. Sight glasses and internal hopper lighting moreover also allow the quick visual check of the fill level.

SmartCenter – Centralised and comfortable actuation

The AMAZONE Precis metering system with integrated hopper inserts ensures minimum residual amounts and even sowing. The seed shaft is driven either mechanically by the land wheel drive or, as an option, electrically via ElectricDrive. Across a wide range of seeds, an outstanding consistency of distribution is ensured. The centralised calibration flap makes for an easy changeover from calibration to drilling.

“The SmartCenter has been inspiring. For calibration one opens the large access door on the side and finds there everything one needs. [...] Fantastic.“

The calibration concept

The calibration trays, directly positioned under the seed hopper, can both be removed from the left hand side via the SmartCenter. Thanks to the two-part calibration trays the decanting into the provided folding bucket is done quickly, simply and comfortably. After the calibration process the calibration trays are simply turned into the storage position with their opening facing downwards.

The digital weighing scales provided as standard enable the exact weighing of the calibrated seed. Thanks to the additional storage space in the SmartCenter of Cataya Super for the standardly-supplied equipment, such as the folding bucket and the digital scales, these are safely stored and immediately at hand. With the Cataya Special, the folding bucket and the digital scales are conveniently stored in the hopper lid.


“The Cataya sets new standards in calibration and adjustment. Here, two aspects have to be especially positively emphasised. For all manual adjustments, the already mentioned 19 mm spanner fits everything – calibration and the adjustment of coulter pressure, sowing depth and harrow heights – is comfortably carried out at the left hand machine side – great.“

Mechanical land wheel drive – reliable drive technology

The mechanical land wheel drive is a reliable but simple and cost-effective solution for the Cataya Special. The mechanical land wheel runs on the right hand side of the seed drill in the driving direction. The driver can therefore easily see the land wheel and can reverse completely into a corner of the field to sow cleanly. The large drive wheel ensures an even, uninterrupted drive to the metering.


Advantages of the mechanical land wheel drive

  • Mounting the wheel on the right hand rear corner ensures a good overview and facilitates easy reversing in field corners
  • Optional control and monitoring via the AmaLog+ in-cab terminal
  • Optional seed deactivation through machine lift-out using the hydraulic top link
  • Transport holder on the rear

ElectricDrive electric metering drive

The harrow-mounted seed drill is equipped with electric drive and also has the ElectricDrive, an electrical metering drive. When equipped with ElectricDrive, the harrow-mounted seed drill has an electrically-driven metering system, the drive is optionally available for the left side, right side or for both sides. The twin drive system allows for automatic switching of eachside separately.

In conjunction with the electric drive, calibration is comfortable and fully automated. The electric drive also offers additional functions such as the pre-metering of the seed in field corners and the increase and decrease of the seed rate during operation. The Cataya features different signal sources for detection of the speed. In addition to the radar sensor or GPS signal, also the speed signal of the tractor can be utilised.

Comfort-Pack 1 with TwinTerminal 3.0

To further simplify the pre-metering, calibration and residue emptying, AMAZONE offers for the Cataya, Comfort-Pack 1 with TwinTerminal 3.0. The TwinTerminal is fitted directly on the seed drill in the SmartCenter. This position offers a decisive benefit: The driver now can carry out the actuation and data input for the calibration procedure directly at the machine and thus the repeated climbing up and down the tractor is no longer necessary.

The TwinTerminal 3.0 consists of a water and dust-proof housing with a 3.2 inch display and four large keys for actuation.

Working position and speed signals

The electric drive offers multiple options for a speed source as well as the working position signal. In this way, depending on the application, a flexible choice between the different sources is possible.

Tramline control

The tramline control can be used to switch off up to 2 x 5 seed rows, so that a tramline can be easily established. The tramline control is made possible via a counter shaft which drives the tramline seed wheels. If a tramline is being created, the counter shaft is locked and stops the tramline seed wheels freely rotating on the seed shaft. The ability to cope with wider tramline gaps satisfies the use of husbandry tractors with tyre widths of up to 900 mm at 15 cm row spacing or 750 mm at a row spacing of 12.5 cm.

Half-side shut-off

Via the half-side shut-off control, asymmetrical tramline rhythms can be created. The half-side control is implemented in the Cataya by means of a centrally divided seed and counter shaft. When the half-side control is activated, the seed and the counter shaft are simply shut off on that side. If the Cataya Super is equipped with the optional twin-sided electric metering drive, the selection of which side is working can be made from the cab.
