Parking the forage wagon
Achtung: When the forage wagon is detached, the pick-
up should be lowered to the ground so that there is no oil
pressure in the hydraulic hoses. This makes coupling and
uncoupling at the tractor easier. Insert the uncoupled
hydraulic hoses in the holders provided at the front of the
wagon to prevent contamination of the couplings.
WHAT TO DO IF ...
1. ... the overload protection feature actuates during
loading?
Check:
a) Is the conveyor drum blocked?
b) Are the blades damaged or blunt?
c) Is the crop pressed excessively in the upper
channel?
Rectification:
Loading speed is too high.
a) Turn cutter drum back with key and free channel,
remove foreign body or turn blade control to
intermediate position.
b) Remove defective or blunt blades and replace or
sharpen.
c) Switch on advance.
2. ... loud noises are produced by the conveyor drum?
Check:
a) Are the blades defective?
b) Are the scrapers aligned?
c) Are the conveyor drum tines bent?
Rectification:
a) Replace defective blades.
b) Align or replace scrapers.
c) Straigten conveyor drum tines.
3. ... the hydraulics do not function?
Rectification:
Cause of error can be located using emergency
manual operation, see chapter on hydraulic block. If
the valve functions can be switched manually, the
electrical system must be checked.
