  • Page 5: Foreword

    The latest settings for the most common types of available fertilizer can be downloaded at any time from Bredal’s website. It is advisable to always do a spreading test using the type of fertilizer to be spread to test the settings recommended by Bredal.

  • Page 6: Safety

    SAFETY The safety distance from the spreading discs is at least 30 meters when these are rotating. If people or animals are within this distance, the tractor’s PTO must be disengaged. Never operate the headland gear or adjust the spreader while the spreading discs are rotating. When loading the spreader, keep foreign objects, such as stones, etc., from getting in the machine’s hopper, as they can cause damage and be very hazardous for the surroundings.
  • Page 7 CONNECTING THE SPREADER When connecting the spreader to the tractor, it is important that it stands horizontally or slightly forward to obtain the best possible spreading results. It is possible to slightly adjust the height by moving the hitch in its bolt holes on the spreader’s undercarriage. The light plug is inserted in the tractor’s light outlet.

    DRIVING DEPENDENT BELT DRIVE, KB3 (SPREADERS WITH MECHANICAL LANDWHEEL DRIVE) To connect, attach the spreader’s hydraulic hose to the tractor’s hydraulic outlet. Engaging and disengaging the application will now be done using the tractor’s hydraulic system. A pilot-operated check valve is installed. This prevents the application wheel from being accidentally engaged if there is a leak in the tractor’s hydraulic system.

  • Page 13: Spreading

    > Application principle Bredal K spreaders are configured with forced application, comprising an adjustable shutter (application door) and a wide belt in the bottom of the container that forces the application of fertilizer. The application rate (belt speed) is driving dependent and the belt on the standard model is driven by an application wheel that is interconnected with the spreader wheel.
  • Page 14 HOW TO USE THE APPLICATION CHART (FOR SPREADERS WITH MECHANICAL LANDWHEEL DRIVE) To use the application chart, you must know the preferred volume in terms of kg/ha as well as the fertilizer’s bulk density in terms of kg/liter. After this, find the setting based on the instructions below. To determine the setting, first convert the volume from kg/ha to liter/ha by dividing kg/ha by the fertilizer’s bulk density (calibration kit).

Adjust the spread-unit position to setting 110 (see the next section ‘Lime spreading adjustment’). Disassemble the fertilizer distributor and screen before spreading lime. Remember that spreading discs used for spreading lime should not be used to spread fertilizer.

  • Page 21: Spreading With Reversed Spread Unit

    IF EXCESSIVE LIME IS DEPOSITED BETWEEN THE WHEEL TRACKS Adjust the spread unit away from the tractor (increase the setting). Adjust 10–20 scale steps at a time. IF EXCESS LIME IS DEPOSITED BEHIND THE SPREADER Adjust the spread unit towards the tractor (decrease the setting). Adjust 10-20 scale steps at a time.
  • Page 22 ATTACHING FERTILIZER EQUIPMENT FOR A DISCS 1. Disassemble the K discs and lime downchute. 2. Attach the fertilizer downchute. Center the downchute on the rubber belt. The distance (A=B) must be the same from the right to the left side. Measure the distance from the side element (A) to the center of the downchute (B).
  • Page 23 6. Adjust the guide plate until the distance from the guide plate to the center bolt is 40–45 mm. Do this by loosening the two bolts and then adjusting the guide plate until it touches the stainless steel top. Make sure that it is possible for the guide plates to tilt up without hitting the stainless steel top disc.

  • Page 24: Spreading Of Fertilizer

    > settings for various types of fertilizer The most precise settings are obtained by using the spreading settings for the type of fertilizer to be used from Bredal’s website www.bredal.com. It is advisable to use these spread charts wherever possible.

  • Page 25: Recommended Universal Settings

    > recommended universal settings If you are unable to find the fertilizer to be used or similar on the website, as an alternative, you can use the recommended universal settings for ordinary NPK, NS, PK and N fertilizers. Spread charts with universal settings for field spreading are found on the following pages. For spreading special fertilizers such as potash, granular urea, ammonium sulfate and N34, the downchute setting must typically be 1–3 scale steps higher than the recommended universal setting.

  • Page 26: Spreading With K Discs With Top Disc (12-24 Meters)

    > spreading with K discs with a top disc (12–24 meters) K discs with a top disc (12–24 meters) can be used instead of A discs, however. Use the lime downchute for spreading of fertilizer with K discs. If K discs are used for to spread fertilizer, it is advisable to have two sets of spreading discs if the spreader is also used for spreading lime: one set for spreading lime and one set for spreading fertilizer.

  • Page 36: Engaging/Disengaging In Headland (Manually)                                                                                          36

    ENGAGING/DISENGAGING IN HEADLAND (MANUALLY) Engage and disengage the spreading in the headland at the right time. General rule: When the discs pass the headland’s tracks, disengage them (for working widths above 24 meters, slightly before this, however). Re-engage when the discs are one working width from the headland’s tracks.

  • Page 37: Late Application With Late Application Equipment                                                                                      37

    -150 Example: A 30-meter working width will be used. According to the settings on Bredal’s website, the PTO rpm should be set at 1000 rpm and the down- chute position at 5.0. According to the table under 30 meters, subtract 150 rpm from 1000 rpm, so that the spreader operates at 850 rpm.

  • Page 38: Driving With A Bogie

    DRIVING WITH A BOGIE For trailers with a bogie, the bogie MUST be locked at all times during road transport, because otherwise there is a risk that the vehicle will begin to sway and cause an accident. Also, the bogie MUST always be locked when driving in reverse as otherwise there is a risk of damaging the lock cylinder.

  • Page 39: Hybrid Power Unit

    HYBRID POWER UNIT Spreaders with hydraulic spread units are available with a PTO-driven hydraulic pump unit. The pump unit is a separate system whose sole purpose is to drive the discs. OPERATION PTO working range: 800–1000 rpm, depending on the disc rpm preferred. Check the following daily: The oil must be visible in the sight glass.

  • Page 40: Troubleshooting

  • Page 41: Incorrect Application Rate (Computer-Controlled Spreaders)

    The application rate is 6 % too low. Change the flow factor from 1.00 to 1.06. The application rate is 3 % too high. Change the flow factor from 1.00 to 0.97. OTHER FAULTS ON COMPUTER-CONTROLLED SPREADERS: See the ‘K Series ISOBUS’ manual.

  • Page 42: Calibrating The Spread-Unit Position                                                                                                      42

    CALIBRATING THE SPREAD-UNIT POSITION To verify whether the scale setting on a K spreader is correct, use the ‘calibration figure’ (scale 120). The ‘calibration figure’ must follow the plate for the downchute as shown in the center photo, and at the same time it must touch the disc and the edge of the cone beside the disc center.

  • Page 43: Floor Belt Adjustment

    FLOOR BELT ADJUSTMENT Normally, the belt does not need to be tightened unless it slips on the rollers and cannot keep up. In many cases, this may be necessary after the first few days of operation, as the belt stretches a little when new. If the belt needs to be tightened, tighten the bolts on both sides of the belt one revolution at a time until the belt moves with the rollers.

  • Page 44: Adjusting Scraper And Downchute                                                                                                         44

    ADJUSTING SCRAPER AND DOWNCHUTE A nylon strip is attached to the rear side of the plate for the downchute which scrapes the belt clean. Adjust the plate for the downchute so the scraper fits snugly against the belt. Do this by loosening the two bolts (A) on each side. It must not be possible for fertilizer to flow between the nylon strip and the belt.

  • Page 45: Centering The Spread Unit

    CENTERING THE SPREAD UNIT The spread unit must be centered. Set the downchute at the same scale value on each side. Make a diagonal measurement from the bolt head (A) on the cone to the bottom tip of the downchute on the opposite side (B). This dimension must be identical when measuring from the right and from the left.

  • Page 46: Checking The Rear Door And Its Basic Setting                                                                                            46

    CHECKING THE REAR DOOR AND ITS BASIC SETTING The basic setting of the rear door must be correct in order for the spreader to apply correctly. It is possible to check the setting by setting the scale at 40 and placing two 40 mm square pipes on the belt underneath the door. If the setting is incorrect, adjust the door on its tension rod. Set the rear door's scale at 40 Place two square pipes underneath the door on each side.
