  • Page 5: Introduction

    This operating manual contains instructions and guidance for operating the machine and setting it for spreading of common types of fertilizer. Since the fertilizer quality can variate quite a lot from year to year and from batch to batch, it is recommended that there shall always be per- formed a spreading test, if there is a slightest doubt about characteristics of the given fertilizer type in relation to its ability to spread on the required working width performing a good result. The newest settings for most common types of fertilizer can be downloaded from Bredals homepage. It is recommended that there always shall be undertaken a spreading test with the type of fertilizer that has to be spread. The spreading test shall be performed with that type of fertilizer that shall be spread in order to try out the required settings by Bredal. It is the operator´s responsibility to make sure that the machine is set correctly and works like it should, so that acceptable spreading pattern could be achieved. Bredal takes no responsibility for spreading errors. Isobus terminal in the tractor and its software: The user surface looks different every time the machine gets connected to another ISOBUS terminal. The reason for this is that terminals have different solutions. Some functions of the spreader depend on the type of software the terminal has. The functions are dependant on that the terminal shall contain the necessary software. In order to perform headland spreading it is necessary to make sure that the terminal contains section control program along with track following program. If the application rating shall be based on the field map, the terminal must also include the software which is able to operate field maps. When the spreader gets connected to the tractor, the spreader’s jobcomputer starts to exchange data with the tractor’s terminal, and only the functions supported by the tractor’s terminal would be active. In case the terminal...

  • Page 6: Security Regulations

    SECURITY REGULATIONS The secure distance from the spreader’s discs is minimum 30 meters when they are in operation. In case there are people or animals within this distance, the tractor’s PTO shall be at once disconnected. Never try to service headland device or make setting adjustments on the spreader when the discs are in operation. Under loading avoid the situation when foreign objects like stone or similar come in contact with the machine’s hopper, as they might cause damage and inflict great danger for the surroundings.

  • Page 7: Connecting The Spreader

    CONNECTING THE SPREADER When the spreader is connected to the tractor, it is important that it is positioned horizontally, or slightly hunched, in order to reach the best possible spreading results. It is possible to adjust a little bit the height by moving the tension in the bolt holes on the spreader frame. The hydraulic hoses for operating the dosing shall be connected to a double-acting tractor outlet. 50-60 l/min shall be used. The hydraulic hoses for operating headland spreading shall be connected to a double-acting headland gear.

  • Page 8: First Time Installation / Set-Up Of Müller Terminal

    FIRST TIME INSTALLATION / SET-UP OF MÜLLER TERMINAL In case an ISOBUS terminal from Müller is delivered together with the machine, some basic set-up shall be done before applying the function of section control. For montaging the tractor assembly kit with GPS antenna, you get directed over to instructions provided by Müller, where it is possible to refer to Müller instructions for operating the programs not relating to spreader’s operation, such as Track-leader, Field-nav, Farmpilot, or other software that can be bought additionally for Müller terminal. The basic set-up of GPS receiver, its activation and the basic encoding for GPS antenna location can be equally found in montage and operating instructions from Müller. When the terminal, tractor assembly kit and GPS antenna are mounted, the socket from the spreader’s ISOBUS is connected, the basic set-up encoding is finished and the spreader can be set into action, press the button for about 3 seconds.

  • Page 9: First Time Set-Up On Existing Terminal In The Tractor

    The encodings shall be used for the spreader to start and stop the dosing at the right time, when turning at headland. Bredal program already contains this information, but not every tractor terminal uploads this data from the spreader when connected. Some terminals apply the encodings correctly. In some cases the tractor´s terminal applies only one or two of the encoded distances.

  • Page 46: Fertilizer Quality

    Try again on other granules, big as well as small, and calculate after that medium granule strength. Granule size can be measured by Bredal sorting box. Fill the space above the sieve, place back the top and shake until there is no more changes to be seen in distribution pattern. Position the box with the top looking upwards again. Now the granule size distribution can be determined.
  • Page 47 density of about 1,0 kg/liter or a bit more. Some fertilizer types have lower density (0,7-0,75kg/liter), with these types it will be difficult to achieve spreading width on 36 meter. Crushed or knobby fertilizer has worse aerodynamic characteristics, therefore it doesn´t fly so far. Large spreading widths require fertilizer that flies very good. These abilities are hard to measure in practice, but a visual evaluation is enough while not difficult to make, it is particularly smooth surface and roundness of the grain that provide the best flying properties.

  • Page 48: Settings For Different Types Of Fertilizer

    Spreading table on the right of the screen shall be chosen. Choose F8/F10 under machine type. Either A or H discs can be chosen (as standard F8/F10 are equipped with A discs) Choose the fertilizer type that is to be spread Choose the working width the spreader will spread on Press to see the result Now the result page appeares, along with the settings that fit for the chosen fertilizer type.

  • Page 49: Spreading Tests And Adjusting Application Rate

    SPREADING TESTS AND ADJUSTING THE APPLICATION RATE There shall always be performed a spreading test in the field to ensure that the spreading result is satisfying. The following factors shall be taken into consideration in connection with a spreading test: • The test shall be taken under dry conditions (field/machine) • The test shall be performed in the field covered with good-size crops - approx. 10 cm vigorous plant cover to avoid offspringing. • Make sure that you perform the test on a flat part of the field, as well as that the trays are positioned as horizontally as possible. • The test shall be performed at the forward speed which is normally chosen for spredning (optimally 14-15 km/t, if the field allows that). • Let approx. 100 -> 200 kg fertilizer through the spreader before the start of the test. There might be layers of old fertilizer, rust etc. on the spreader´s discs and vanes, which must be worn off before the spreader starts to show a constant spreading pattern. • The trays are placed at 1/2 working width at both sides from the middle track (of 3 tracks). Move forward along the 1st track back to the 2d and forward again along the 3d.

  • Page 50: In Case There Is Too Much Fertilizer In Between The Tracks

    >If there is too much fertilizer in the middle between tracks Encode a smaller value under downchute position. Encode about 2 scale intervals less. In case the following test shows that 2 intervals is too much, the difference between the two tests indicates how much the scale shall be moved back for. > If there is too much fertilizer behind the spreader Encode a bigger value under downchute position.

  • Page 51: Connecting/Disconnecting At Headland (Manual)

    CONNECTING/DISCONNECTING AT HEADLAND (MANUAL) If spreading is done without applying section control, the spreading shall be connected and disconnected at the right time. A common rule is: When the discs go past the headland track, spreading has to be disconnected. The connecting is necessary when the discs are at one working width away from headland track.

  • Page 52: Density

    DENSITY Fill the calibration bucket with fertilizer, tap it a few times lightly against the floor and fill it fully. Swipe off the top. Then hang the bucket on the weighing installation onto checkmark (X1). Set the counterweight so the arm balances. Read the fertilizer´s density next to the bolt end. (Calibration kit belongs to additional equipment) If the weight gets out of adjustment or when a control weighing has to be done, it is performed by filling the bucket with water. When the weight arm has acquired the balance, the bolt end shall point out at 1,0 at the scale. If not, the bolt shall be adjusted until the setting fits.

    -2,0 -200 -1,0 -100 -1,0 -150 -0,5 -100 -0,5 -150 -150 Example: The given working width is 30 meter. PTO revolutions and downchute settings for the fertilizer to be spread is according to Bredal homepage 1000 rev/min and for downchute 5,0. As per the table under 30 meter there shall be deducted 150 rev/min from the 1000, which gives the optimal PTO of 850 rev/min. Downchute position is normally 5,0, according to the table 0,5 shall be deducted, so the optimal downchute setting is 4,5.

    ERROR IN APPLICATION In this section there can be found description of the most common mistakes that might appear, along with causes to different error messages, and some help on searching for errors among the spreader´s electronic components. > Error in application rate The most common error appears when the spreader’s conveyor belt is not moving with the correct speed, or isn´t moving at all. The alarm can often go off quite briefly and disappear automatically again as soon as the mistake has disappe- ared, this case is not a sign of any mistake on the spreader, but is conditioned by the fact that application rate has been shortly out of application rate area.

  • Page 56: Basic Settings And Adjustment Of Downchute Positions

    BASIC SETTINGS AND ADJUSTMENT OF DOWNCHUTE POSITION In order to achieve the best possible spreading picture it is important that basic settings for downchute are correct. Turning points for both downchutes shall be centered over the middle of the plates, downchutes position shall also be adjusted correctly. This control and adjustment shall be performed if parts of spreading unit or downchute have been separated.
  • Page 57 Downchutes shall be separated, as the base plates need to be used for adjustment. Loosen M8 bolt inside, then unscrew the unbraked unbraco screw out. Make sure that control disc, that centers downchute in the hole, comes back at its place when downchutes shall be put back together.
  • Page 58 After adjustment downchutes have to be put together, they shall be able to easily turn, when the central screw has been tightened; when they appear to turn rather easily, the counter screw shall be tightened. Make sure you get both the central disc and the big tightening disc exactly at their places. Mount downchutes and a drawbar back at place. Now the basic settings for downchute scale shall be controlled / adjusted.

  • Page 59: Control/ Adjustiment Of Downchute Scale

    > Control / adjustment of downchute scale Use the following procedure to make sure that downchutes are correctly positioned. Working width on ”36” meters is encoded into the computer. ”Auto, no flow control” shall be chosen under downchute control. Go back to operating picture and click ”start spreading” Note, headland spreading may not be activated, as downchutes would then not assume the right position, all sections shall be on. After ”start spreading” has been clicked on, the downchutes will move out and po- sition themselves in front of the little arrow cut in the bottom plate of downchutes. Unless the arrows are right across each other, they shall be adjusted so that basic settings are fitting.

  • Page 68: Maintenance And Lubrication Of Spreading Unit

    MAINTENANCE AND LUBRICATION OF SPREADING UNIT It is very important that spreading unit is properly maintained/lubricated. There exists a generall rule interval for frequency of spreading unit lubrication, besides it is relevant that e.g. headland device is lubricated, esp. after washing and before the spreader is put away after the season. Moreover it is important to test the headland gear function every time the tightening on the spreader takes place, and after a long standstill period. Tightness of the belts shall also be controlled regularly. Below it is described in a detailed way how the spreader shall be inspected and maintained.

  • Page 69: Lubrication

    > Lubrication There are 2 lubrication places inside of the spreading unit, they shall be greased every 200 operating hours. If the spreader has been thoroughly washed inside, it shall anyway be processed and headland gear shall be lubricated as well. Headland gear shall be sprayed with oil on the axle where the claw-coupling slides up and down.
