III. CUTTING HEIGHT
Cutting height adjustment changes the
angle (S) of the cutterbar in respect to
the ground (fig. 20). This is done by
changing the length of the top link (V)
(photo 19).
When working in normal conditions, the
length of the top link should be adjusted
so as to have an angle (S) of about 6@
which corresponds to a cutting height of
5 to 7 cm (2" to 2 3/4"). When it is
required to cut lower, the length of the
top link should be shortened.
When it is required to cut higher,
increase the length of the top link. This
is recommended when working in rough
conditions.
When it is required to cut higher still,
replace the 4 wear plates initially
mounted on the FC with 4 raised wear
plates supplied with the machine for
this purpose.
IV. SAFETY BREAKAWAY.
In rough field conditions the ground
speed should be reduced. The machine is
protected with a safety breakaway and if
an obstruction is encountered the unit
must swing to the rear. The resistance
of the breakaway is determined by the
spring washer length which must be
positioned as shown in fig. 21.
The nominal length (Y) should be 73 mm
(3") but this length can be adjusted as
necessary to suit the varying condi-
tions.
NOTE : DO NOT OVERTIGHTEN.
To reset the machine, reverse the
tractor.
