  • Page 6: Safety

    SAFETY The safety distance from the spreading discs is at least 30 metres 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

    CONNECTING THE SPREADER When connecting the spreader to the tractor, it is important that it is suspended horizontally or tilts slightly forward to obtain the best possible spreading results. The spreader must not tilt backwards, not even when the hopper is full. The spreader must be mounted directly behind the tractor, i.e. perpendicular to the direction of travel, and it must be centred squarely on the tractor’s central axis.
