CUTTING HEIGHT
The cutting height can be changed by tilting the an-
gle (Z) (fig. A) of the cutterbar. To change the angle,
turn the top link handle (B) (fig. A) until the desired
cutting height is obtained.
For most conditions the skid shoes should be parallel
to the ground. Mowing too close to the ground can
cause excessive wear of the discs and knives, the
crop to be soiled and regrowth can be delayed.
SWATH STICK
The wooden swath stick can be adjusted into 6 posi-
tions for when working in varying crop conditions.
OPERATING THE MOWER
Release lock by applying pressure with the hand
palm (arrow 1) and fold front safety bar (V) downwards
(arrow 2) (photo 36) till it is automatically locked in
working position.
ENSURE THAT THE SAFETY
CURTAIN IS COMPLETELY IN
PLACE AROUND THE CUTTER-
BAR.
Safety curtain will avoid projection of most foreign
objects.
Always allow a few minutes for oil to spread in the
cutterbar before engaging PTO when changing
cutterbar from transport to operating position.
Before cutting, engage tractor PTO and slowly
increase speed up to 540 rpm.
Do not be disturbed by the high pitched whine of the
discs. This will be reduced to some extent when
cutting.
Forward speed must be adapted to working conditions and should be reduced when mowing dense crops.
A slower ground speed may have to be used in heavy down crops.
Check correct fixation of plugs (C) (photo 36) on the outer and inner disc cone.
Replace lost or worn plugs immediately.
ADVERSE FIELD CONDITIONS
NEVER MOW IN STONY OR ROCKY GROUNDS.
Extra care and precautions should be taken in rough or debris-ridden fields. The following adjustments should
be made to the mower in these conditions to minimize the possibility of foreign objects being deflected by the
cutting knives.
1) Tilt the angle (Z) of the cutterbar back towards the horizontal position by turning the top link handle (B)
(photo A) to raise the cutting height of the knives.
