Make sure that the permissible total weight is not exceeded. Note the permissible axle load, the approved braking load and the permissible tyre
load capacity; see also "Axle load calculation" on page 123
.
Is the solid fertiliser broadcaster mounted correctly?
z
Could fertiliser be lost while travelling?
Check the fill level of the fertiliser in the hopper.
The metering slides must be closed.
The ball cocks must also be closed on single-action hydraulic cylinders.
z z
Check the tyre pressures and the function of the tractor brake system.
Do the lights and identification on the solid fertiliser broadcaster comply with the national regulations for operation on public roads? Make sure that warning signs, reflectors and auxiliary lights are correctly placed.
Road travel with the solid fertiliser broadcaster
The road handling and the tilting, steering and braking performance of the tractor are all altered by the attached solid fertiliser broadcaster. For example, the high permissible load capacity will reduce the weight on the front axle of the tractor and may affect the steering.
z
Be aware of the changed driving behaviour.
z z
Make sure that you have sufficient vision when driving. If vision is restricted (e.g. when reversing), another person is required to direct the driver.
Do not exceed the permissible maximum speed.
z z z
Avoid sudden turns when driving uphill or downhill or across a slope. The change in the centre of gravity may increase the danger of tipping. Travel over uneven, soft ground (e.g. entering a field, travelling over road edges) with great care.
Set the lower link on the three-point linkage so it is rigid to prevent the machine from rocking.
Passengers are prohibited on the solid fertiliser broadcaster during transport and operation.

Using the calibration charts
Information on the fertiliser charts
The values in the spreading charts have been determined on the solid fertiliser broadcaster test installation.
The fertilisers used have been sourced from the fertiliser manufacturers or from storage depots. Experience shows that your fertilisers - even with identical specifications - may have different spreader properties because of storage, transport and many other reasons.
This means that the solid fetiliser spreading settings specified in the fertiliser charts may result in a different spreading amount and a poorer fertiliser distribution.
Therefore observe the following instructions:
z
Always check the actual spreading amount with a calibration test
(see
7: Calibration test and discharging residue, page 75
).
z
Check the working width of the fertiliser distribution with a practice test kit

– The RAUCH DiS Fertiliser Identification System (special equipment) permits rapid simple determination of the spreader settings when using unknown fertilisers.
– The fertiliser identification can be carried out without problems and using only a few ancillary items, even when in the field.
z
– The fertiliser to be investigated is first grouped according to its constituents. Reference illustrations are then used to identify more closely the properties of the fertiliser. After identification, the spreader setting can be determined from an enclosed table.
Practice Test
– The settings for fertiliser types not listed in the spreading charts can be calculated with this option.

NOTE
On the MDS Quantron M Eco solid fertiliser broadcasters, the calibration test is carried out on the Quantron M operating terminal.
The calibration test is described in a separate operator's manual for the
Quantron M operating terminal. That operator's manual is included with delivery of the Quantron M operating terminal.

Calculating the nominal discharge amount
Calculate the nominal discharge quantity before starting the calibration test.
Calculate exact ground speed
The exact ground speed must be known to calculate the nominal discharge amount.
1 Drive the half full solid fertiliser broadcaster over a 100 m distance in the
field. Note the time required.
2 Read the exact ground speed on the scale of calibration test calculator.
Figure 7.1: Scale for calculating the exact ground speed
75
7 Calibration test and discharging residue
7.1.2
The exact ground speed can also be calculated by the following formula:
Ground speed
(km/h)
= 360 time over 100 m
Example: You require 45 seconds to travel 100 m:
360 = 8 km/h
45 s
Calculating the nominal discharge amount per minute
To calculate the nominal discharge amount per minute you will require: z the exact ground speed, z z the working width, the desired application rate.
Example: You wish to calculate the nominal discharge amount at one discharge. The ground speed is 8 km/h, the working width is set at 18 m and the application rate should be 300 kg/ha.
NOTE
For some application rates and ground speeds the discharge amounts are already shown in the calibration charts.
If you do not find your values in the calibration charts, they can be found with the broadcast test calculator or from a formula.
Calculation with the broadcast test calculator:
1 Move the tab until it is at 300 kg/ha under 18 m.
2 The value of the nominal discharge amount for both discharges can now be read above the value of the ground speed of 8 km/h.
Z
The nominal discharge amount per minute is 72 kg/min.
If the calibration test is conducted at one discharge only, the total value of the nominal discharge amount must be halved to calculate the value for one discharge.
3 Divide the read value by two (= number of discharges).
Z
The nominal discharge amount per discharge is 36 kg/min.
76
Calibration test and discharging residue 7
Figure 7.2: Scale for calculation of the nominal discharge amount per minute
Calculation with formula
The nominal discharge amount per minute can also be calculated with the following formula:
Nominal discharge amount
(kg/min)
= ground speed (km/h) x working width (m) x application rate (kg/ha)
600
NOTE
Calculation for example:
8 km/h x 18 m x 300 kg/ha = 72 kg/min

Constant fertiliser application is only possible at an even ground speed.
Example: 10% higher ground speed results in 10% underfertilisation.

Safety
NOTE
Service and maintenance work involves additional hazards that do not occur during operation of the machine.
Take particular care when carrying out servicing and maintenance work.
Work very carefully and with awareness of the dangers.
Observe the following instructions in particular: z z z z z z
Welding and work on the electrical and hydraulic systems must be carried out by qualified technicians only.
When working on the raised solid fertiliser broadcaster it may be in dan-
ger of tipping. Always secure the solid fertiliser broadcaster with suitable supports.
Always use an appropriate strap for lifting the solid fertiliser broadcaster with lifting tackle.
Power-operated components (adjusting lever, metering slide) may crush
and shear. Make sure that there is no one in close proximity to the movable parts during maintenance.
Replacement parts must at least comply with the technical standards specified by the manufacturer. Original replacement parts, for instance, are manufactured to meet these standards.
Before all cleaning, maintenance and repair jobs, and when repairing faults, turn off the tractor engine and wait until all rotating parts of the machine have come to a stop.
Note the warning in chapter 3: Safety, page 5
. Take particular note of the
instructions in section 3.7: Maintenance and repair, page 10 .

Wearing parts and bolted connections
Checking wear parts
Wear parts are: spreader vanes, agitator shaft, agitator finger , outlet,
hydraulic hoses, deflection and protection device.
z
Check the wear parts.
If these parts show visible signs of wear, deformation or holes, they must be replaced, otherwise the scatter pattern will not be correct.
The durability of the wear parts depends in part on the material spread.

8.2.2
8.2.3
Checking bolted connections
The bolted connections are tightened to the specified torque and locked at the factory. Vibration and shocks, particularly in the first hours of operation, may loosen bolted connections.
z z
Check the solid fertiliser broadcaster when it is new about every 30 operating hours to make certain it is structurally sound.
Check all the bolted connections regularly for tightness, and at least before the start of the spreading season.
Some components (e.g. spreader vanes) are mounted with self-locking nuts.
Always use new self-locking nuts when mounting these components.
Check the flat areas of the spreader discs
IMPORTANT
Do not over-bend the flat spring!
The flat spring tension must securely retain the main and extension vanes on the spreading disc. If the flat spring is over-bent it loses its necessary tension for securing the spreader vanes.
If the spring tension is too low the locking pin disengages and can cause severe material damage.
X
X
When adjusting the spreader vane position push the locking pin care-
fully into one of the position holes.
If the spring tension is too low replace the flat spring immediately.

Cleaning
We recommend cleaning the solid fertiliser broadcaster immediately after every use with a soft water spray to maintain its value.
To facilitate cleaning, the safety mesh guards in the hopper can be folded up
(see chapter 8.4: Opening the safety mesh guard in the hopper, page 86 ).
The following instructions must be observed for cleaning: z z
Clean the discharge ducts and the area of the slide guides from below only.
Clean oiled machines only at washing points with an oil separator.
z
When cleaning with high pressure never direct the water jet directly at warning signs, electrical equipment, hydraulic components and sliding bearings.
After cleaning, we recommend treating the dry solid fertiliser broadcaster,
especially the coated spreader vanes and stainless steel parts, with an environmentally compatible corrosion protection agent.
A suitable polishing kit can be ordered from authorised dealers for use in treating rust spots.

General Information
The modern technology and design of our solid fertiliser broadcasters and comprehensive, continuous testing at our factory fertiliser spreader test area ensures that you will have a perfect scatter pattern.
In spite of the care taken during manufacture of the machines deviations in fertiliser application or some type of fault is always possible even when used as designated.
The reasons for this may be: z z z z
Changes in the physical properties of the seeds or the fertiliser (such as variable grain size distribution, variable density, grain size and surface, treatment, coating, moisture).
Clumping and wet fertiliser.
Wind drift (stop spreading at high wind speeds).
Blockages or bridge formation (e.g. because of foreign objects, bag residue, wet fertiliser ...).
z z z z
Uneven ground.
Wear of wear-out parts (e.g. agitator fingers, vanes, discharge).
Damage from external causes.
Poor cleaning and care to prevent corrosion.
z z
Incorrect drive speeds and ground speeds.
Not conducting broadcast test.
z
Incorrect machine settings.
Pay close attention to the machine settings. Even a slightly incorrect setting may adversely affect the scatter pattern. Therefore, before every use of the spreader and during work check that your machine operates properly and that the application is sufficiently precise (run a calibration test).
Particularly hard fertiliser types, such as Thomas fertiliser and kieserite, increase the wear on the spreader vanes.
The spreading width to the rear is approx. ½ working width. The total broadcast width is approx. 2 working widths with the triangular spreading pattern
(M1 disc: 10-18 m depending on the type of fertiliser).
Always use the supplied sieve to prevent blockages caused by foreign objects or fertiliser clumping.
No claims for compensation for damages that are not part of the solid fertiliser broadcaster itself will be accepted.
This also means that no liability will be accepted for damages resulting from spreading errors.

When continuing spreading in the field after boundary spreading note the following: z
If you are using the TELIMAT swing it out of the spreading area.
The slides are closed and opened at different distances from the edge of the field.
z
Open slides: when moving away from the edge at a distance of approx. 1 working width
(x) from the edge track (T).

Telimat T1 (accessories)
The Telimat T1 is a remote controlled border and edge spreading unit for working widths of 10 - 24 m (20 - 24 m just border spreading).
The Telimat T1 is mounted on the left of the solid fertiliser broadcaster, looking in the direction of travel. It is actuated by a double-acting control valve from the tractor.
NOTE
Attaching the Telimat to the solid fertiliser broadcaster is described in a separate assembly manual. This assembly manual is supplied with the Telimat.
9.5.1
Setting the Telimat
The Telimat T1 is prepared for the spreading work depending on the type of
fertiliser, working width and the desired border spreading type on the basis of the setting table (see sticker). You can choose between border spreading setting (considerable under-fertilisation next to the edge of the field) and edge spreading setting (virtually constant spreading volume up to the edge of the field).

Environmentally optimised boundary spreading at working widths
of 20 - 24 m:
To optimise the scatter pattern we recommend reducing the output on the
boundary side by 30 %.
Version M with hydraulic slide control (FHK 4, FHD 4): single sided volume reduction not possible. The volume must be reduced by 30 % on both sides.
If the symbol - - is entered in a column in the setting table (sticker) of the Telimat T1, then the following applies: z
Edge spreading with Telimat is not possible since the spreading pattern for field spreading is already similar to a spreading pattern for edge spreading. This also applies to edge spreading of 20-24 m.

9.5.2
Correcting the spreading width
The values in the setting chart are standard values. If there are deviations in fertiliser quality it may be necessary to correct the setting.
In order to correct the given setting of the Telimat it is only necessary, in most cases, to change the number scale to optimise the spreading width up to the field edge.
z z
To reduce the spreading width from the standard setting in the setting chart: move the deflector plate position on the number scale towards the
lower number value.
To increase the broadcast range from the standard setting in the setting chart: move the deflector plate position on the number scale towards the
higher number value.
If there are greater deviations it may be necessary to move the Telimat housing along the letter scale.
z z
To reduce the spreading width from the standard setting in the setting chart: move the Telimat along the letter scale towards the lower letters
(in alphabetical order).
To increase the broadcast range from the standard setting in the setting chart: move the Telimat along the letter scale towards the higher letters
(in alphabetical order).
NOTE
Guide plate setting
z
In order to be able to move the guide plates along the number scale you only need to release the outer fixing nut (d).
z
If the guide plates are to be moved along the letter scale both fixing nuts
(d, e) need to be released.

Instructions for spreading with the Telimat
The Telimat is set to the position required for the selected spreading method from the tractor with a double-acting control valve.
z z
Boundary spreading: bottom position,
Normal spreading: top position.
IMPORTANT
Spreading errors caused by not reaching the end position of the Telimat
If the Telimat is not completely at the end position, you may encounter spreading errors.
X
X
Make sure that the Telimat is always in the specified end position.
When switching from boundary spreading to normal spreading, actuate the control valve until the Telimat is completely in the top end position.

Line spreader device RV 2M for growing hops and fruit
The RV 2M line spreading device is inserted in the top link of the clevis hitch.
The line spreading device is arranged in such a way that a row (row pitch: approx. 2-5 m) to the left and to the right of the solid fertiliser broadcaster is spread with a strip approx. 1 m wide, depending on the type of fertiliser.
Because of the small spreading width, the spreader vanes must be set to position A1-A1. Under no circumstances should the spreader vanes be set greater than C4 or D2 since otherwise they will be in contact with the line spreader device.
For safety reasons, after fitting the RV 2M line spreading device the spreader vanes should be turned over by hand.
Small corrections can be made between the steps in the adjustment by mounting the fertiliser spreader higher or lower.
120
Options 11
The spreading volume can be calculated to the effective spreading width using the fertiliser chart.
Calculation
z
Two rows are to be spread.
z
The distance between the two rows to be spread is 3 m.
Z
This means that the effective working width is 6 m.
However, since there are no details for fertiliser setting in the fertiliser chart for a working width of 6 m, it is recommended to take the setting values for
12 m working width from the fertiliser chart.
If you want to spread 200 kg/ha at a working width of 6 m you need to take the setting values for 12 m working width from the fertiliser chart and set the metering slide for 100 kg/ha.
11.9
Border spreading device GSE 7
Limits the spreading width (either right or left) to the range between approx.
75 cm and 2 m from the centre of the tractor track to the outer field edge. The metering slide that points to the field edge is closed. z z
Fold the border spreading device downwards for border spreading.
The border spreading device must be hinged up again before two-sided spreading.

Guarantee and warranty 13
Guarantee and warranty
Rauch units are manufactured with modern production methods and with the greatest care and are subject to numerous inspections.
Therefore RAUCH offers a 12-month warranty subject to the following conditions: z
The warranty begins on the date of purchase.
z z z
The warranty covers material and manufacturing faults. Our liability for third-party products (hydraulic system, electronics) is limited to the warranty of the manufacturer of the equipment. During the warranty period, manufacturing and material faults are corrected free of charge by replacement or repair of the affected parts. Other rights extending beyond the above, such as claims for conversion, reduction or replacement for damages that did not occur in the object of supply are explicitly excluded.
Warranty services are provided by authorised workshops, by RAUCH factory representatives or the factory.
The following are excluded from coverage by the warranty: natural wear, dirt, corrosion and all faults caused by improper handing and external causes. The warranty is rendered void if the owner carries out repairs or modifications to the original state of the object of supply. Warranty claims are rendered void if RAUCH original spare parts were not used. Please follow the directions in the operator's manual. In all cases of doubt contact our factory representatives or the factory directly. Warranty claims must be submitted to the factory by 30 days at the latest after occurrence of the problem. The date of purchase and the serial number are required.
If repairs under the warranty are required, they must be carried out by the authorised workshop only after consultation with RAUCH or the company's appointed representatives. The warranty period is not extended by work carried out under warranty. Shipping faults are not factory faults and therefore are not part of the warranty obligation of the manufacturer.
No claims for compensation for damages that are not part of the solid fertiliser broadcaster itself will be accepted. This also means that no liability will be accepted for damages resulting from spreading errors. Unauthorised modifications to the overload trailer or solid fertiliser broadcaster can lead to consequential damage for which the supplier accepts no liability.
In the event of intent or gross negligence by the owner or a senior employee and in cases where according to the product liability law there is liability for personal injury or material damage to privately used objects in the event of faults in the object of supply, the supplier's liability exclusion will not apply. It will also not apply in the case of faults in properties that are explicitly assured, if the assurance had the purpose of protecting the purchaser against damage that does not arise from the object of supply itself.
