Conversion to Imperial rates and measurements
If you are still more familiar with the imperial rates of lbs/acres and of m.p.h.
the following simple conversion system will be of converiance to you: To find
the rate of lbs/acre deduct 11 % of the given rates in kg/ha (kilogrammes
per hectare). Example: CAN (Calcium Ammon. Nitr.) 27% N
Spread width: 12 m
Tractor speed: 12 k.p.h. (km/h)
Setting: 25
Spread rate: 148 kg/ha
Calculation: 10 % of 148 = 14.8
1 % of 150 = 1.5
11 % of 150 = 16.3
148.0 ./. 16.3 = 131.7 lbs/acre at 12 k.p.h. = 7.5 m.p.h.
Conversion for metric figures of this chart to Imperial figures:
A. Spinner disc heights above ground/crop
1cm = 4/10 inch
2cm = 8/10 inch
3cm = 12/10 inches
5 cm = 2 inches
45 cm = 17 3/4inches
50 cm = 19 2/3inches
55 cm = 21 2/3inches
60 cm = 23 2/3inches
63 cm = 24 8/10 inches
65 cm = 25 9/16 inches
68 cm = 26 3/4inches
70 cm = 27 1/2inches
75 cm = 29 1/2inches
76 cm = 30 inches
77 cm = 30 1/3inches
B. Effective spreading widths
10 m = 32 3/4feet
12 m = 40 feet
15 m = 50 feet
16 m = 52 1/2feet
18 m = 59 feet
20 m = 65 1/2feet
21 m = 69 feet
C. Speeds 1 k.p.h. = 0.6 m.p.h.
6 k.p.h. = 3.7 m.p.h.
8 k.p.h. = 5.0 m.p.h.
D. Weights 1 kg = 2.200 lbs

May we draw your attention to the fact that the individual spreading
characteristicsof thefertiliserhaveabig influenceonthe workingwidths and
spread rate. For this reason setting values can only be taken as a guide.
The spreading properties depend on
- The deviations of the physical data (bulk density, grain sizes, sliding
ability etc.) - even within the same kind and brand.
- The varying fertiliser condition caused by influences of weather or of
storing conditions.
For this reason we can not assume a guarantee that your fertiliser even
with the same name and from the same manufacturer will have the same
spreading characteristics as that of the fertiliser stated in the setting chart.
The stated setting recommendations for the lateral distribution refer
solely to the distribution of the weight (spread rate) and not to the
nutrient distribution (this especially refers to fertiliser blends).
With your ownership of an AMAZONE fertiliser broadcaster you will have
access to the „AMAZONE fertiliser testing service“ because we would
like to assist you to operate in the most cost effective and environmentally
safeway. The„AMAZONE fertiliser test service“ determinesthe individual
spreading characteristics of your fertiliser from a 3 kg fertiliser sample
received and provides setting recommandations for the working widths
required by you. The AMAZONE fertiliser testing service is especially
recommended when uncertainties prevail regarding fertiliser origin, fertiliser
description or fertiliser condition or when the fertiliser has not yet been
included in this setting chart.
Please ask your AMAZONE dealer/distributor for your country’s AMAZONE
Fertiliser Testing Service telephone number and enter it below so that it is
readily available.

Hints for avoiding spreading errors:
1. Storefertiliserproperly(i.e.dry,separatebytypesandbymanufacturers).
2. Set the machine according to the data of this setting chart or accoring
to the recommendations by the AMAZONE fertiliser testing service.
3. Prior to starting to spread conduct a spread rate check.
4. When having unknown types of fertiliser as well as also for a
general check set working widths should be checked with the aid
of the mobile spread width test kit (option).

2.0 Setting the mounting height
Set the machine to the operating height in the field to be spread with a filled
hopperexactlytothesettingsgiveninthesettingchart.Themountingheight
is measured from the spinner discs front- and rear-edge each to the surface
of the ground.
2.1 Normalfertilising
The mounting heights (in cm) stated are valid for normal fertilising. For
normal fertilising the swivel blades of the spinner vanes are usually
in a „downward“ position (Fig. 1).
For fertilising in spring when the crop has grown already to a height of 10 -
40 cm, one half of the grown height should be added to the mounting
heights stated (e. g. 80/80). Thus at a plant height of 30 cm = mounting
height 95/95 should be set. In taller crop heights the machine should be set
upaccordingtothesettingsmentionedforlatetopdressing(para.2.2).When
crops are very dense (rape) the fertiliser spreader should be set with the
mounting height stated (e. g. 80/80) above the crop height. Should this still
be impossible due to a higher plant height, the machine should also be set
up according to the settings for late top dressing (para. 2.2).
2.2 Latetopdressing
For late top dressing the swivel blades of the vanes should be
swivelled in the „up“ position without slackening the nuts and
without the use of any tools (Fig. 2). This will raise the throwing curve
of the fertiliser.
The mounting height of the spreader should be set in the crop by raising the
tractor’s three-point-linkage to such a height that the gap between the ears
of the corn and the spinner discs measures approx. 5 cm (2 inches) (Fig.
3). If necessary the lower link pins may be mounted in the lower link holes
provided in the machine’s main frame.

3.0 Setting the spread rate
Take the shutter slide position directly from the setting chart - under
consideration of the type of fertiliser to be spread, working width, intended
speed of operation and wanted spread rate. The mentioning of (kg/l)
refers to the bulk density of the spreading material.
Example:
Kind of fertiliser: AN 34% N prills (group 4)
Working width: 12 m
Operational speed: 8 k.p.h.
Desired spread rate: 400 kg/ha
Nowchosefromthesettingtableforthespreadrateof406kg/hatherequired
shutter slide position: „28“.
Determiningtheshutterslidepositionforspeeds notmentioned inthe setting
chart:
Example:
Kind of fertiliser: AN 34% N prills (group 4)
Working width: 12 m
Operational speed: 6 k.p.h.
Desired spread rate: 400 kg/ha
desired speed (6) [km/h] x desired spread rate (400)[kg/ha]
10
Then look up at 12 m working width in column 10 k.p.h. for the calculated
value (240) the table value (238) to find the shutter slide position (25).
Determining the shutter slide position for working widths not
mentioned in the setting chart:
Example:
Kind of fertiliser: AN 34% N prills (group 4)
Working width: 8 m
Operational speed: 8 k.p.h.
Desired spread rate: 400 kg/ha
desired working width (8) [m] x desired spread rate (400) [kg/ha]

Thenlookupat10mworkingwidthincolumn8k.p.h.forthecaluclatedvalue
