Trailed Fertiliser Spreader

For precision farming

All the features of our AC2 mounted models are reproduced in the AD range of trailed fertiliser spreaders. Strength and simplicity of management come together in all our AD models.

The product is fed to the discs by gravity to ensure a high degree of accuracy in the desired dose.

SPREADER UNIT

The AC2 spreader unit, included in our AD range, is made from nodular cast iron. It features gears and axles hardened in a watertight casing in oil bath. The devices in contact with the fertiliser are made from high quality stainless steel.

It is very strong to ensure the long life of the unit.

Its power take off has universal grooves with six channels and the rotation rate is 540 r.p.m., duplicating this speed in the spreading discs.

Adjustment of the working width is carried out through a combination of several devices: blades on the spreading disc and variation in the product dropping point. A comprehensive instruction manual explains, for each type of fertiliser, how to select our chosen working width and allows us to work with precision and safety.

For AGUIRRE no fertilisers are impossible – there is always a specific adjustment for each case, and, of course, with high rates of accuracy.

Its maximum flow rate is 180 kg per minute which allows the operator to work at high doses and speeds.

An agitator constantly cleans the product through holes, slowly rotating in order to not generate dust at the bottom of the hopper.

REGULATION

The AD models incorporate the following regulation elements:

Dosage in kg/ha. We can choose from several systems:

Constant flow. A millimetric index indicates the position of the opening of the product outlet windows from the hopper to the spreading discs. Our working speed should be constant. The opening/closing of the passage of fertiliser is made by a hydraulic on/off system.

A variant of this system is that of electrical control via the cab console. Manually, but without stopping the progress of the tractor, we can increase the of fertiliser drop flow and, therefore, the kg/ha.

Flow proportional to the speed. By means of electronic positioning control of the electric actuators that open and close the passage of fertiliser to the discs. This allows us to vary the working speed while maintaining the kg/ha desired.

Working width. To adapt to any need of the farmer based on the type of land farmed. This is done very simply with the help of the Instruction Manual. Adjustable from 12 to 24 m for the majority of fertilisers and maintaining a coefficient of variation below 10% as required by the European standards.

ELECTRONICS

The regulating systems are assisted by electronic devices that command and manage:

RMA 220 for constant flow regulations for its electric management from the cab.

MCK 2000 for systems with flow proportional to progress via wheel sensor or, as an option, GPS antenna, for managing the following:

Necessary flow at each moment based on the forward speed

To modify the dose during the work

Hopper level and rotation control of the devices

Hectare counter and speed counter

Edge of field work

EDGE WORK

With a view to achieving a correct fertilization of the edges with the least possible loss of fertiliser (for economic and environmental reasons), the AD models can work under two different edge systems:

BORDER SX

To move along at the very edge of the fields and to distribute the fertiliser only inside of these. Without any fertiliser waste.

BORDER TX

To move along the inside of the fields usually coinciding with the tracks of the sprayer. The device can be adjusted for the various working widths of our sprayer, choosing in each case the option of efficiency, environmental or intermediate.

Both systems comply with the European standard not to spread more than three parts per thousand of the product outside the field.

DISTRIBUTION CURVES

The quality of product distribution (whether fertiliser or seeds) is compared by the EUPA Testing Station in Palencia.

All the regulation proposed in the instruction manuals of the machine relates to actual tests performed in this official and independent laboratory and with coefficients of regulation within the European rules.

The instruction manual shows the types of curves obtained for each fertiliser and at each possible dose and working width. This is of great help to the user for deciding between the different regulations that are possible.
