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.

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.

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 –

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.

For road transport the machine can quickly be
folded to a transport width of 3 m. The oversized
tyres provide an especially smooth run also on
the road. As standard the Cirrus comes with a full
braking system and corresponds in all respects
to the German traffi c regulations for permissible
forward speeds of up to 40 km/h.
