headland area and spread out progressively
across the field. Consequently, the frame
pitch is not constantly being adjusted unless
field conditions and straw concentrations vary
significantly.
4.3.2 Setting the Tilt Control Circuit
To adjust and then remember a new pitch
setting, firstly reset the circuit as follows.
Fully tilt the rake rearwards. In this position,
set the taps to reset, as below. Pressure
rearwards again fully.
NOTE:
take care when
changing tap settings as
some movement of the
machine can occur which can
reduce the rearward pitch a little.
Turn any
taps off first which will remain off.
Pressure rearwards fully to reset the circuit.
Next, still tilted rearwards fully, set the taps to
fold, which allows the machine to be operated
without the pitch control.
Operate the machine until the desired pitch is
obtained.
Whilst at this pitch, change the taps to the
working setting. The pitch is now memorised.
The machine can be tilted rearwards, upon
releasing this pressure it will return back to
the desired pitch.
4.3.3 Fine tuning the Pitch Setting
Once a pre-set pitch is in use it
can be fine tuned without going
through the resetting procedure.
In the working configuration (above figure),
ensure firstly the machine is fully tilted
forwards, in work. If this is too high or low,
adjust as follows.
Change over the tap settings to the fold
configuration (figure, below, left) and then
adjust the pitch until the required setting is
achieved.
this new position, change the taps back to the
working setting (figure, above) to memorise
the new position.
4.4 Work to transport
Follow the procedure outlined
below to keep the pre-set pitch for
next time before folding and
unfolding.
With the machine
fully tilted rearwards
,
change the taps to the fold setting as
illustrated opposite.
Remember when adjusting tap settings to
turn those off first which will remain off.
Provided the tap settings are
changed over from work to
fold and back with the machine
