Another way to improve the discharge capacity is to fine-tune the setting of the drum base (1)
using the setting screw (2).
The drum base is adjusted in the factory.
- The distance from the blades (4) to the drum base at the rear (3) is a = 6-7 mm.
The nature of the crop (for example, a dry crop) may require readjustment of the drum base.
Measuring the distance between the drum base and blade
Prerequisites:
– Lifting unit is fully raised.
– The machine is shut down and secured, see page 41.
Work steps:
• Walk under the machine.
• At the rear edge of the drum base (3), use a hexagon wrench (5) to check along the entire
length that the distance to the blades (4) is the dimension a = 6-7 mm.
