Too high a tractor's PTO rpm cause major air swirls which bow the grass against discs, and this
lead straight to impairing mowing quality.
-
Too low a tractor's PTO rpm cause impairing of mowing quality, and in extreme cases the
mower stops operating (due to low line speed of knife).
-
In case of mowing low grasses head guard should be lifted in order to reduce air blows which are
generated on discs and also reduce the guard's pressure onto grass being cut.
-
On soft meadows reduce the cutterbar's pressure onto the ground by adjusting support springs
Fig. 17.
Shape of the stubble
0°, 3° and 5° slope of the cutter bar
NOTE:
Improperly relieved cutting unit of the mower will cause increase of
cutterbar pressure on the ground which will lead to faster wear of sliding
skids, overload of cutterbar, higher fuel consumption, damage to the stubble
and contamination of the fodder.

Mower clogging
When operating the mower pay attention to variable conditions on field, which may influence
the mower clog, such as: terrain unevenness, height and density of grass as well as other objects in
the grass. In order to avoid clogging, mowing speed should be adjusted to the mentioned conditions.
In order to prevent any clogging, also inspect tensioning of belt on belt gear.
In order to remove the machine clogging, lower the cutterbar onto the ground, disconnect the
drive, take ignition key off and pay particular attention, remove excess material using sharp tool.
After clearing the machine check if nothing has been damaged. When eliminating the mower's
clogging, use also safety means for operator, so protective gloves and tight wear, due the risk
wound, abrasion and damage of skin.
CAUTION:
Removing clogs and jams while the machine is in operation can lead to the
accident !
