A level deck is essential for a uniform cut over the whole lawn.
With the mower on a flat surface, check that the tyre pressure is correct, check the float spring tension, and if
necessary turn the adjuster screw (fig. 7 "D").
lf a satisfactory parallel setup cannot be achieved, adjust the register n' 10 fig. 2.
To adjust the mowing height, set the lever no6 fig. 1 on the lowest setting "40", fit two 30 mm shims at the sides
under the edge of the deck, and set the wire fig. 2 n'12laul.
DRIVE BELTS - HYDROSTATIC
AXLE
These belts are self-adjusting and do not require_ any adjustqent. Simply check the spring tension. To replace
the belts, release the tension springs ("G", fig. 14).
PTO BELT
Caution! This belt is special, use only original belts.
To replace, proceed as already eiplained for replacement of the hydrostatic transmission belt (upper spring "G",
f i s . 1 4 ) :
1) Remove the guard above the deck by unscrewing the two knobs fig. 2 n" 13.
2 ) R e l e a s e t h e s p r i n g f i g . 1 2 , i t e m E .

To adjust the tension, use the register of the wire fig. 2 n" 8 which stretches the spring. When the PTO lever PTO
fig. 1 n' 2 is engaged the spring must be stretched (its length must increase by 30 mm).
Adjust the blade brake on the cutting deck pulley (fig. 12). When the blades are engaged, the shoe must be in line
and 4 mm away from the belt; adjust the hook "F"'fig. 12.
D E C K B E L T
When replacing the belt, adjust the belt as shown in fig. 1B; to set the tension, use the register fig. 19. lf you have
a tool for measuring belt tension, the tension on initial installation is 55 kg. CAUTION! At subsequent adjustments
once the belt has been used, the load must not exceed 38 kb; otherwise, the belt may be damaged. lf no tension
measurement tool is available, proceed as follows:
1) if the belt is new, apply a force of B kg in the longest section; the belt must give way by 15 mm (fig. 20);
2) if the belt has already been used, apply a force of 5.5 kg for a dip of 15 mm (fig. 20).
