Blade/Cut Adjustment

BARONESS LM180 TRIPLE MOWER –BLADE/CUT ADJUSTMENT
Before commencing any blade adjustments it is important that the cutting units are
thoroughly cleaned and dry.
To check that the blades are cutting
correctly, use a strip of paper as shown.
With the strip of paper held square to the
bottom blade, rotate the cutting cylinder
and see if the blades cut the paper. Never
rotate the cutting cylinders using your
hands as the blades are very sharp and
can cause serious injury. Use a short
length of wooden pole to rotate the
cylinder.
If the paper is not cut then you will
need to lower the cutting cylinder
down onto the bottom blade.
To do this, first of all loosen the top
locking nut on the cylinder adjustment
mechanism. Repeat this for both sides
of the cutting unit.
Once the top locking nut is loosened you need to
lower the cylinder down slightly onto the bottom
blade.
To do this firstly lower the bottom adjusting nut
by turning it clockwise a couple of flats.
Then repeat his exercise with the top nut, turning
it clockwise a couple of flats.
This will have the effect of lowering the cutting
cylinder.
Repeat this procedure for both ends of the cutting
unit.

Check the cut again by using a strip of paper
as previously explained. Check both ends of
the blades and not just in the middle. Once
again please remember to never put your
hand into the cutting cylinder.
If the paper is still not cut correctly, repeat
the blade lowering procedure as described
above.
If one end of the cutting cylinder cuts the paper but the other end does not, then only adjust the end
that is not cutting, but be aware that this could have an effect on the other end so always check both
ends with paper after making any adjustment.
Keep adjusting both ends until the paper is cut right across the length of the bottom blade.
Once the blades are cutting paper right across
the length of the bottom blade then you need
to check that you do not have excessive blade
contact.
To do this you need to use another strip of
paper but this time hold it flat along the
surface of the bottom blade.
When you rotate the cylinder the paper
should not be cut but should just leave an
indentation line. If it does this it is set ok. If it
cuts the paper then the contact is too great
and the blades will need adjusting to provide
slightly less contact. This is done by turning
the blade adjuster nuts anti-clockwise by a
very small amount in order to increase the
gap slightly.
Only adjust the side which is too tight. If both
sides are too tight then adjust them both but
remember to only use very small adjustments
and keep checking both sides.
The blades are correctly adjusted when both
sides cut paper when it is held square to the
bottom blade but only leaves an indentation
in the paper when it is held flat along the
bottom blade.
