u Machine 110 4x4 (mowing deck with a mowing coverage of 110 cm):
The drive of the mowing deck blades is provided by belt (2) via an electromagnetic
transmission (1) and belt pulley (3) and furthermore belt pulley (4) under the mowing
deck cover. Because of the demands placed on them, the tension of belts declines over
time and it is necessary to re-tension them.
} Move the mowing deck elevation adjustment lever to the lowest position.
} Tension belt (2) using the tensioning draw bar with nut (5) so that the spring has
a length of 80 mm.
} Tension belt (4) using the tensioning draw bar with nut (6) so that the spring has
a length of 135 mm.
6.3.11 Mowing deck - removing it from the machine
The following procedure applies for both mowing deck models, i.e. for mowing decks with
a mowing coverage of 92 cm and 110 cm.
} Lower the mowing deck to the lowest position.
} Loosen nut (2) to fully loosen spring (1) on both sides of the machine. The spring must
be completely loosened, otherwise there is a risk of a part of the mowing deck being
ejected and causing injury!
} Loosen the tension of the mowing deck drive belt by loosening nut (3). Slide the belt out
of the belt pulley (4).
} On both sides screw out bolts and nuts (5) and (6), connecting the suspension brackets
to the mowing deck.
} Slowly pull the mowing deck to one of the sides out of the machine.
When remounting the mowing deck on to the machine, proceed in reverse order to the
demounting procedure.
After remounting the mowing deck on to the machine, do not forget to set its correct
above ground height
tension the mowing blade drive belt
6.3.12 Checking and adjusting the travel drive belt
The following procedure applies for both mowing deck models, i.e. for mowing decks with
a mowing coverage of 92 cm and 110 cm.
Because of the demands placed on it, the tension of the travel drive belt declines over time and it is
necessary to re-tension it. Therefore, regularly check the level of tension.
When the amount of bend increases, it is necessary to adjust the tension. The belt is
tensioned by a pulley and spring from the underside of the machine.
Perform the belt tension adjustment by tightening the nut on the bolt of the tensioning
draw spring so that the spring is tensioned to a length of 46±1 mm.
Do not over-tension the belt above this level, this will reduce its lifetime and
may also cause damage to the transmission!
( 6.3.7), tension the deck elevation spring
( 6.3.10).
