or replace them if necessary.
BELT PROBLEMS
PROBLEM
POSSIBLE CAUSES
REMEDY
THE TRAVEL DRIVE
BELT OF THE
MACHINE IS SLIPPING
The travel drive belt is insufficiently
tensioned
Check the tension of the belt and tension it if
necessary
(
6.3.12
)
The travel drive belt is damaged or
worn out
Check the condition of the belt - replace it if necessary.
The engine belt pulley or transmission
belt pulley is damaged.

The clutch mechanism is blocked by
a foreign object
Check the clutch and remove any foreign objects
THE TRAVEL
DRIVE BELT OF
THE MACHINE IS
CREAKING

)
Check the working order of the brakes. If they are not
in order
have them adjusted at an authorised service
centre.
THE TRAVEL DRIVE
BELT JUMPS OUT
DURING OPERATION
The travel drive belt is insufficiently
tensioned
Check the tension of the belt and tension it if
necessary
(

MOWING DECK PROBLEMS
PROBLEM
POSSIBLE CAUSES
REMEDY
THE MOWING DECK
MOWS UNEVENLY
Grass and dirt accumulated inside the
mowing deck
Check the condition of the blades and sharpen or
replace as necessary (
6.3.6
)
Blunt or deformed blades
Check the condition of the blades and sharpen or
replace as necessary (
6.3.6
)
Damaged or worn out blade shaft
Check the condition of the shaft.
One or both the belts are insufficiently
tensioned
Check the tension and tension it if necessary (
6.3.8
a
6.3.9
).
AN UNMOWED STRIP
REMAINS BETWEEN
THE BLADE ROTORS
Blunt or deformed blades
Check the condition of the blades and sharpen or
replace as necessary (
6.3.6
)
Damaged bearing housing
Check the condition of the bearings and based on
findings perform a repair or replacement. When
mowing thick grass or grass that is too wet, an
unmowed strip may remain. The travel speed should
be adjusted to respect the mowing conditions by
shifting into a suitable gear. The engine should not run
with the throttle valve fully open.
THE MOWING DECK IS
RIPPING OUT TURF
Bent blades
Check the condition of the blades and replace as
necessary (
6.3.6
)
Damaged bearing housing
Check the condition of the bearings and based on
findings perform a repair or replacement.
The drive belt is insufficiently tensioned
Check the tension of the drive belt (
6.3.8
and
6.3.9
)
and tension it if necessary.
Inappropriate mowing height
Check the mowing height and adjust if necessary. Turf
is ripped out more frequently on uneven terrain.
THE MOWING DECK
DOES NOT EJECT
GRASS
Grass has accumulated inside the
mowing deck
Remove the grass from the underside of the mowing
deck. In wet conditions, the ejection chute and the
lower side of the outlet from the mowing deck may
clog up with grass. Do not mow wet grass.
The drive belt is insufficiently tensioned
Check the tension of the drive belt (
6.3.8
and
6.3.9
)
and tension it if necessary.
Inappropriate travel speed
The travel speed should be adjusted to respect the
mowing conditions by shifting into a suitable gear.
The enginAe should not run with the throttle valve fully
open. When mowing high grass, first mow once at
a high mowing height, then once more at the normal
height. Follow the information in chapter
5.5.3
.
Incorrectly installed blade
Check, particularly after replacing blades, that the
blade is installed correctly.
