5.3 GRASS CUTTING
5.3.1 Engaging the blade and forward movement
When you have reached the area to be mowed,
– put the accelerator into the «FAST» position;
– engage the blade by putting the lever into position «B»;
– to begin moving, operate the speed regulation controls taking care to release the
pedal very gradually and with particular caution as already described.
Engage the blade with the cutting deck in the highest position, and then gradually
lower to the height required. To achieve good collection and even cutting of the grass,
choose a forward speed to suit the quantity of grass to be cut (height and density) and
the lawn's humidity, in line with the following indications ( ➤
for mechanical drive models):
– High and dense grass - wet lawn 1st speed
– Average condition grass 2nd - 3rd speed
– Low grass - dry lawn 4th speed
NOTE The fifth gear is solely for moving from one area to another on
horizontal surfaces.
➤ Hydrostatic drive models:
The speed has to be adapted to the condition of the grass in a gradual and progressive
way by moving the speed change lever.
The speed should always be reduced if you note a reduction in engine speed, since a
forward speed that is too fast will not cut the grass well.
Disengage the blade and put the cutting deck in the highest position whenever you
need to get past an obstacle.
5.3.2 Cutting height adjustment
The height is adjusted by moving the lever with 7 height positions.
5.3.4 Lawn maitenance
1. To keep a lawn green, soft and attractive, it should be cut regularly without damaging
the grass. A lawn can be composed of different types of grass. If the lawn is
cut frequently, grass and roots grow more vigorously, forming a solid grassy bed.
