Height of Cut Adjustment

Preparation
Height of Cut Range
It is much easier to adjust the two
rear units by swinging them out. In
order to make this easier ensure
that the removable pin is kept clean
and greased. Periodic wire brushing
of this pin prior to greasing will ease
the removal of these pins. You will
also find it easier to remove the pins
and swing out the rear units if the
machine is parked level ground.
The Baroness GM2800 has four
height of cut ranges as indicated on
the decal which is located to the left
of the operators seat. Each range is
selected by changing the height
adjustment brackets . The position
of the bracket retaining bolts
stipulates the range selection as
indicated at the top of the decal.
For example, the column shown
second from the left will allow
heights of cuts from 30mm to
66mm. This is selected by lining up
the bolt holes ‘top right and middle
left’, as indicated by the solid white
dots which signifies bolt positions.
This second column range is the
most popular range for most
applications and is the default
setting of a new machine.

Adjusting the height of cut range
Height of cut Adjustment Bracket
Height of cut adjustment bracket
retaining bolts. This photograph
shows the bracket set in the default
position with the bolts located ‘top
right and middle left’.
Loosen all three height adjustment
shim retaining nuts. It is important
to loosen all three nuts at once and
not to try and adjust one bracket at
a time. Trying to adjust one bracket
at a time will make the task very
difficult as this will have the effect of
trying to twist the deck.
Remove all six of the shims from
above and below the bracket.
Again it is important to do this to
all three positions at once and not
to try doing one adjuster at a time.

This photograph shows all of the
shims removed from above and
below the bracket. This should be
done on all three units before
proceeding.
All three adjusting brackets can now
be moved to their new position.
This can be done one bracket at a
time.
Support the deck underneath the
bracket to be moved using a
suitable item such as a mallet as
shown.
Remove the two bracket retaining
bolts.
With the bolts removed manoeuvre
the bracket up or down until the
desired holes are aligned as
stipulated by the height setting
decal.
With the desired holes lined up, refit
the retaining bolts. Repeat this
exercise for all three brackets.

Changing height of cut
First of all make sure that the height of cut range is correct as explained above.
You can now see that the bolts have been
inserted into their new position of ‘top left and
middle right’. If you refer back to the height
chart decal you will see that this now puts this
deck into the lowest range of 20 to 56mm.
To adjust the height of cut, first of
all loosen all three height
adjustment s shim retaining nuts. It
is important to loosen all three nuts
at once and not try to adjust one
bracket at a time. Trying to adjust
one bracket at a time will make the
task very difficult as it will have the
effect of trying to twist the deck.
Once all three nuts are loose,
remove shims in order to achieve
the desired pattern as stipulated on
the height range decal. If you need
to increase the height of cut you will
need to remove shims from above
the bracket and replace them below
the bracket. To decrease height,
remove them from below the
bracket and replace them above the
bracket.

Repeat this exersice for all five decks.
This photograph shows a shim that has
been removed from above the bracket
being reinserted below the bracket in order
to increase the height of cut. Repeat this
exercise for all three height adjustment
brackets before attempting to tighten the
adjuster shim retaining nuts.
Once the shims on all three adjuster points have
been moved to the desired position, tighten the
retaining nuts firmly. Do not leave them loose
as this will cause the shims to fall out during
operation. This photograph shows the height
range bolts selected to ‘top left and middle
right’ with the shims arranged ‘five below and
one above. This will give a height of cut of
50mm as shown on the height decal.
