Cleaning, maintenance and repairs
12.5 Replacing the spreading vanes and swivel vanes
•
The technical condition of the spreading vanes, including their
swivel blades, is essential for uniform lateral distribution of the
fertiliser on the field (i.e. forming strips).
•
The spreading vanes are made of especially wear-resistant
stainless steel. Nevertheless, we remind you that the spreading
vanes and their swivel vanes are wear parts.
Replace the spreading vanes and / or swivel blades as soon as holes
from abrasion are visible.
12.5.1 Replacing the spreading vanes
WARNING
Danger of ejection of spreading vanes caused by the uninten-
tional release of fixing bolts and quick-release screw connec-
tions!
•
When replacing the spreading vanes, it is essential to replace
used self-locking nuts of the fixing bolts with new ones. A used
self-locking nut no longer has the required clamping force to
produce a secure screw connection.
•
Ensure that the open side of the disc spring is toward the
spreading disc before tightening the wing nut. Only in this posi-
tion can the disc spring pretension and secure the quick-release
screw connection.
It is essential to ensure that the spreading vanes are installed correct-
ly! The open side of the U-shaped spreading vane must be facing the
direction of rotation.
When exchanging the spreading vanes and swivel blades, use the
assembly paste provided. This is the only way to ensure that the
specified tightening torque is sufficient.
