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.
u Machine 132 4x4 (mowing deck with a mowing coverage of 132 cm):
The drive of the mowing deck blades is provided by driving belt (2) via an electromagnetic
transmission (1) and belt pulley (3) and furthermore via distribution belts (5) and (7)
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 (4) so that the spring has
a length of 85 ± 1 mm.
} Tension belt (5) using the tensioning draw bar with nut (6) so that the spring has
a length of 85 ± 1 mm.
} Tension belt (7) using the tensioning draw bar with nut (8) so that the spring has
a length of 75 ± 1 mm.
6.3.11 Mowing deck - removing it from the machine
The assembly and disassembly of the cutting deck, being a complicated and
dangerous, must be performed by an authorized Service Centre.
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!
