Preface

Sow successfully and harvest successfully

sowing makes the harvest …

... says an old German proverb which is still valid today,

because now, as then, the foundations for consistently

high yields are laid during sowing and so to get the

plant off to a good start the majority of demands

made on the sowing technology should be fulfi lled as

far as possible.

The ground rules for sowing can be clearly defi ned

by the following guidelines:

maintenance of planting depth in relation to crop

type, planting depth should be neither too shallow,

however, nor too deep!

Optimal lateral and longitudinal distribution of the

seed!

Suffi cient seed coverage, no open seed furrows

showing but not buried out of sight!

Creation of suffi cient fi ne soil around the seed!

Suffi cient reconsolidation and restoration of the

capillary water action!

In addition to the usual demands on arable farming

economic factors are becoming increasingly im-

portant and so, making sowing technology that is

infl uenced by both dynamic and economic para-

meters more necessary. These, in detail, are:

high outputs due to larger working widths and/or

higher forward speeds

moderate pulling and tractive power requirements

reduced fuel consumption

low running costs

The Cirrus large area seed drill

Both agronomical and economic parameters were

considered during the development of the Cirrus seed

drill and so two Cirrus series, as a matter of principle,

need to be offered to fulfi l the many, diverse operational

situations found worldwide.

This means that alongside the Cirrus Super the Cirrus

Special is available for light to medium soil types.

With options and supplementary equipment on offer

for both Cirrus series it allows an optimal matching to

individual needs.

The right sowing technology for any spectrum of operation

Cirrus Super –

the best technology with a working

width of 4 and 6 m

At the heart of the Cirrus Super is the PacTeC coulter.

Guided coulter discs connected to the wedge-ring tyres

in a double parallelogram arrangement provide an even

seed placement with a minimum deviation from the

desired planting depth. Four PacTeC coulters in con-

junction with one wedge-ring tyre form one sowing unit.

The individual sowing units are connected via a

hydraulic pressure equalisation system that ensures

an optimum adaptation to the differing soil contours

giving an even soil pressure from the roller and a con-

stant planting depth across the entire working width.

The 400 mm diameter discs ensure a reliable and

smooth coulter travel even at forward speeds of up

to 20 km/h – both guarantors for an even and high

emergence percentages.

The use of hardened boron steel for the discs results

in a long operational life with corresponding low

wearing costs. The following exact harrow levels and

covers the seed with suffi cient fi ne soil. The central

depth adjustment and the hydraulically adjustable

harrow pressure allow the adaptation to changing soil

conditions at any time.

Special

The right sowing technology for any operational situation

Cirrus Special – the new seed drill

with a working width of 3, 4 and 6 m

The Cirrus Special differs from the Cirrus Super in its

use of the RoTeC coulter technology. Depending on

soil type and forward speed two coulter options are

available, the RoTeC or the RoTeC+ coulter.

For operating on medium to heavy soils at forward

speeds faster than 12 km/h the 400 mm diameter

disc RoTeC+ coulter with up to 50 kg coulter pressure

should be the fi rst choice on the Cirrus Special. For

operation on lighter soils and in conjunction with ave-

rage forward speeds slower than 12 km/h the 320 mm

diameter RoTeC coulters with a coulter pressure of up

to 35 kg can be used.

On both coulter executions the planting depth is

maintained by the adjustable depth limiter and cleaning

disc. The coulter pressure, either set manually or, as

an option, hydraulically provides the desired depth in

all conditions. The seed furrow is formed by the angled

sowing disc and the integrated furrow former. In all

cases the discs are made from boron steel and incor-

porate a wear resistant depth limiter and cleaning disc

and a furrow former made from hard cast alloy result

to ensure a minimum of wear and tear costs. The

exact harrow provides the seed coverage.

Cirrus Super and Cirrus Special – Twins with a lot in common

Towing and turning –

all so manoeuvrable

The standard equipped lower link drawbar

in conjunction with the specifi c design of

the swivel headstock allows the Cirrus to

turn on the headland at the full steering limit

and so it’s the turning circle of the tractor

that is the limiting factor. Small headlands

and extremely short turn round times are the

typical characteristics of areas which have

been well thought out with the Cirrus.

To avoid deep wheel marks and thus soil

compaction both Cirrus series, with the

exception of the Cirrus 3001, allow headland

turning on the full width of the wedge ring

tyres.

The narrowest of turning circles – Cirrus

Optimum positioning of the seed hopper –

Filling, calibration and emptying made easy

The arrangement of the seed hopper at the front of

the machine near to the tractor rear axle offers many

advantages. A large portion of the seed hopper weight

is thus transferred directly on to the tractor rear axle

improving traction and so the coulter units are not af-

fected by varying fi ll levels and the quality of planting

depth remains constant at all times. The layout and

the covering of the hopper offer optimum accessibility

for all tasks – including fi lling and calibrating as well

as emptying and cleaning.

Twins

Two-row disc harrow unit – seedbed preparation and sowing in one pass

The two-row disc harrow unit loosens, crumbles and

levels the seedbed prior to sowing. In this way two

operational passes can be combined.

For conservation farming additionally any surface

straw is again distributed and incorporated and a

plentiful clearance, even at high forward speeds, is a

feature of the two-row disc harrow unit. The result?

No blockage from straw or crop residues.

The operational intensity of the discs can be optimised

whilst on the move from the tractor seat and telescopic

side discs provide an even match between bouts

without ridging.

Perfect bearing sealing

The combination of felt rings and extremely high quality

face seals protect perfectly the 2-row angular contact

ball bearing races. These sit in oil fi lled reservoirs

providing lifelong lubrication and avoid the need for

grease nipples and the maintenance time of the disc

elements is substantially reduced. Face seals have

been used in the construction industry for decades

for sealing rollers on the running gear of track-laying

vehicles they’re proven to work reliably under the har-

dest of operational conditions.

Rubber sprung buffer elements –

safe and maintenance-free

The discs are mounted on a sprung rubber suspen-

sion system for individual soil contour following. In

addition the rubber sprung buffers act as an over-

load safety device on stony soils. In this way a safe,

maintenance-free operation of the disc harrow sys-

tem is ensured at a constant, even working depth.

Pre-running wedge-ring tyres

On the Cirrus Super four PacTeC coulters, together

with one wedge-ring tyre, form one sowing unit and

all these sowing units are linked via the hydraulic

equalisation system. Whereas on the Cirrus Special

High seed placement quality due to special coulter guidance

the wedge-ring tyres are arranged rigidly via a separate

coulter frame with each set of 4 RoTeC+ or RoTeC

coulters following the pre-running wedge-ring tyre.

PacTeC coulter system RoTeC+ coulter system

The wedge-ring tyre –

two functions combined

In principle the wedge-ring tyres in the Cirrus have

two tasks:

1. With 12.5 cm row spacing the targeted reconsolida-

tion of the soil under each of the four disc coulters.

2. For road transport and turning on the headlands

four of the wheels are pushed down. This also allows

the machine to safely leave the fi eld even in the

toughest conditions. These four wheels are equipped

with brakes so that it is permissible for the machine

to be transported on the road at up to 40 km/h.

Top marks for contour following, consistency of planting depth and operation – simply ingenious

Pre-consolidating wedge-ring tyres –

roll fi rst, then sow

On both the Cirrus Super and Cirrus Special the pre-

running wedge-ring tyres provide a targeted re-conso-

lidation below the seeding area. Due to the restoration

of the water draw the seedling is suffi ciently supplied

with water resulting in a quick early growth. After

any rainfall superfl uous water is able to drain away

through the un-consolidated soil between the wedge

rings and this is the best protection against surface

capping. The loose soil near to the surface also prevents

unwanted water evaporation.

This mixture of re-consolidated and loose soil also im-

proves the gaseous interchange around the seedling

which is especially important for a healthy and sustai-

nable crop development.

Interchangeable from

machine to machine

The control of all important functions

on both Cirrus series is done via the

AMATRON+ on-board computer.

This includes all operational func-

tions as well as the initial set-up

such as, for example, calibration.

AMATRON+ is an operator terminal

that overlaps from seed drills to fer-

tiliser spreaders and fi eld sprayers,

etc enabling the optimum application

rate control and operation.

AMATRON+ on board computer

As standard the Cirrus is equipped with a mechanical

star wheel drive whereas, as an option, full electric

drive is available. Electric drive allows simplifi ed cali-

bration routines and the individual adjustment of the

seed rate. The comprehensive electro-hydraulic control

via AMATRON+ facilitates the control of all functions

such as headland management or operational intensity

of the disc harrow unit from the tractor cab.

In addition the on-board computer controls and mo-

nitors the tramline functions. Via the serial interface

integrated into AMATRON+ the Cirrus in combination

with a GPS terminal can also be used for part-area

specifi c sowing operations.

AMATRON+

The metering makes the difference

Normal seed

Medium seed

Fine seed

The metering system is suitable for all kinds of seed

and seed rates from 2 to 400 kg/ha. The large diameter

of the metering wheels results in a low circumferential

velocity preventing damage to the seed. Changing

over from fi ne seed to normal seed is done within

seconds just by exchanging the metering cassettes.

All the drivelines, metering system and delivery compo-

nents are already well proven by use in large numbers

in all AMAZONE pneumatic seed drills.

Hopper extension for Cirrus

With the 600l extension the hopper of the Cirrus 3001

or 4001 can be increased to 2800l and that of the

Cirrus 6001 to 3600l. In this way downtime caused by

refi lling is reduced.

In addition the increased hopper size allows the indi-

vidual machine to be matched to the fi lling requirements

of specifi c fi eld sizes.

Wheelmark eradicators for sowing

on the plough furrow

When operating the Cirrus on ploughed, un-reconso-

lidated areas, wheel mark eradicators are offered as

optional equipment. The wheel marks of the towing

tractor are broken up and levelled.

Optional equipment

Post-consolidation roller harrow for oil seeds on dry sites

The cultivation of rape on light and dry sites might

possibly require reconsolidation above the seeding

area. Especially in these cases the following roller har-

row is offered instead of the exact harrow. It does not

have any infl uence on the depth control of the coulter.

Fuel consumption and running costs

are the decisive factors regarding

the attractiveness of specifi c arable

farming techniques. This also includes

such one-pass sowing.

In this context over several years

comprehensive test results have

been gathered in cooperation with

the DLG’s test department. Here,

using the Cirrus large area seed drill

has proven to be extremely profi -

table, depending on the kind of soil

and topography of the terrain. For

sowing with its integrated seedbed

preparation system a fuel consump-

tion of 5.5 to 6.0 l/ha was ascertai-

ned.

Profi tability is their strength –

labour costs when operating the Cirrus

Test results sowing with the Cirrus large area seed drill

Wearing costs can be calculated with an average of

2,00 to 2,50 €/ha. These low values result in the main

from the long lifespan of the front cultivation discs and

the hardened boron steel discs of the sowing units.

In addition the maintenance-free bearings with inte-

grated face seals and the overload safety device via

rubber sprung buffer elements help keep repair costs

at a minimum.
