If the trailer is pneumatically connected with the tractor in a correct manner (line 1 and 2), the
black push-button should be pulled out; the trailer's wheels are blocked by pulling the red
push-button out – figure (3.18).
4.5 LOADING OF MATERIAL
Load box can be loaded only when the trailer is connected to the tractor and positioned
horizontally. Always aim at distributing the load uniformly in the load box. This will ensure
trailer stability when travelling and correct wheel axle and drawbar loads. When loading the
load box, it is recommended to use a loader or belt conveyor. When loading silage directly
from a self-propelled forage harvester or combine harvester, the load can be compacted by
pressing with the sliding wall - consequently, much more silage can be transported.
When compacting the load, the sliding wall should be moved very slowly so as not to apply
excessive pressure to the tailgate.
Before loading, check that the tailgate and chute slide gate are closed. Confirm that there are
no objects in the load box. Avoid throwing material into the load box from a great height
