Preparation of the disc harrow
The disc harrow is usually supplied for sale in a ready-to-operate condition. Due to
the limitations of the means of transport, it is also possible to deliver it in a partially
disassembled condition – usually by disconnecting the roller.
When preparing the unit for operation for the first time, its components (roller)
must be assembled. To this end, place the disc harrow on a flat hard surface in a position
where the roller can be manoeuvred. A lifting device with a load capacity of at least 500
kg in (700 kg in the case of a rubber roller) must be used for transporting the roller to
ensure stability during transport. Position the arms in the harrow holders and connect the
arms to the roller clamp using screws (Fig. 5).
Fig. 5 Arm and roller clamp connection.
Prior to operation check the technical condition of the disc harrow, in particular that of
the working parts and screw connections.
CAUTION! The correct procedure for mounting the rollers in the arm
clamps requires that the screws are tightened evenly diagonally so that
the entire plane of the arm brackets is flush with the plane of the roller
clamp profile. This provides the most secure way of connecting the roller
arms to the machine!
