Use of the rear equipment
The tractor must be shut down and the parking brake must be applied when
adjusting the rear equipment.
E
F
The position of the following harrow can
be adjusted at points E and F. On clay soil,
the following harrow most effectively turns
fine soil to the right sowing depth if the tines
are nearly perpendicular to the ground and
the harrowing speed is 8–10 km/h.
Spring adjustment
When using a spiral roller for rear equipment, the
roller is loaded by a draw spring. This spring should
not be tightened excessively – the tension is correct
if the soil surface is levelled and no traces of tines
can be seen behind the roller. When the roller is
used, the harrowing speed can be slightly higher
than when using a rearboard, i.e. 8–12 km/h.
The spiral roller and following harrow can also
be used simultaneously.
If necessary, the following harrow can be turned
up and locked with a pin.
Suitable harrowing speed for this combination
is 8–10 km/h.
Control with a linkage bar Control with a dedicated hydraulic circuit
The rearboard control options are as follows:
•
Control with the frontboard hydraulic circuit, in which case
the movement is conveyed to the rearboard via a linkage bar.
In this case, the relative position of the rearboard is adjusted
with a crank connected to the linkage bar.
•
Control with a dedicated hydraulic circuit, in which case the
rearboard is controlled by separate cylinders connected in series.
The hoses for this circuit are marked with yellow.
