Border Discs; Maintenance; Sensing Wheels - horsch Tiger AS Series Operating Instructions Manual

Border discs

The edge discs prevent the formation of dams
at both sides of the machine.
Border disc
Setting
The border discs must be matched to the work-
ing conditions.
For this purpose one can adjust the depth of the
discs and their angle of attack via the respec-
tive gate.
Once the cultivator is in working position, the
discs should slightly roll along the surface.
However, they should not stop, since this would
cause single sided wear.
The rotation angle of the discs must be adapted
according to the working speed and the piled up
amount of soil and residue.
Tiger 3 MT
The border discs must be folded down from
transport to working position before work is
started.
Before transportation on public roads
they must be folded up again to maintain
the transport width.

Maintenance

The border disc bearings are maintenance free.
The service notes for disc levelling must be
observed.

Sensing wheels

The Tigers are equipped with support wheels
as required for the working width. The support
wheels keep the machine steady and maintain
the working depth in the ground.
The wheels only have a sensing function. They
are not designed as load bearing transport
wheels.
The side wings must not be lifted by the wheels.
Sensing wheel
The setting is made after the depth setting has
been completed.
When starting work the sensing wheel is raised
or only the lower bolt is removed.
Lower the cultivator into the soil and adjust
the sensing wheels when the working depth is
reached.
The depth stop is set by the lower bolt. The
upper bolt serves as stop, so that the wheel is
lifted at the headland.
Setting
Raise the sensing wheel and pull out the
¾
adjustment bolt.
Lower the sensing wheel to the ground.
