4.3 OPERATION
After having correctly hitched the machine, sit down in the driving
seat and proceed in the following way:
- Lower the machine to the ground on its wheels by means of the
power lift.
- Engage the power take-off whilst the engine idles.
- Engage the forward speed gear and begin to work with the
power take-off at full rate.
CAUTION
Do not depress the accelerator pedal too sharply when the power
take-off is engaged.
- Drive a short distance and then check that the grass is being
cut at the required height.
A few factors must be considered in order to choose the right
mowing height:
- the type of grass being cut;
- the tractor’s ground speed;
- optimum mowing height regulation.
A good cut is obtained with a low ground speed and with the tool
rotor spinning at high speed.
CAUTION
To avoid breakages or damage, the speed of the tractor must
not exceed 6-8 kph when the mower is operating.
Never turn sharply or reverse when the mower is operating, even
if the wheels are the swiveling type.
Never ever reverse with the machine resting on the ground.
DANGER
The spinning tools may throw up stones or other sharp objects
as the mower operates.
Constantly check to make sure that there are no bystanders,
children or animals within the machine’s range of action.
4.3.1 MOWING ADJUSTMENT
DANGER
Mowing height adjustment is a dangerous operation. Wear work
gloves and use suitable tools in a good condition.
Proceed in the following way to adjust the mowing height:
- Stand the tractor on flat ground, hitch the machine, then lift it
with the power lift;
- Adjust the mowing height as follows:
a) remove the spacers from the wheel axles and position them
below or above the fixed hub until the required mowing height
has been obtained.
b) make sure that all four wheel pins have the same mowing
height setting.
The mowing height is obtained by the position of the spacers on
the wheel pin (Fig. 7). Remove the plug (1 Fig. 7) from all the
pins to change the position.
DANGER
Mowing height adjustment is a dangerous operation. Wear
work gloves and use suitable tools in a good condition.
4.3.2 USEFUL TIPS
Here are a few useful suggestions on how to resolve some of the
problems that may occur during work.
Cut plants shredded to much
- Slightly lift the cutter from the ground, adjusting the height with
the wheels (the blades of the cutter must not touch the ground).
- Increase the ground speed.
Cut plants not shredded enough
- Slightly lower the machine towards the ground.
- Reduce the ground speed.
- Do not work in soil that is too wet.
Rotor clogged
- Soil too wet to work.
- Raise the machine from the ground.
- Reduce the ground speed.
- Do not work where the grass is too tall. If necessary, remove
any material that has built up at the sides of the rotor to prevent
overheating.
The machine jolts over the ground or vibrates
- Foreign bodies locked between the knives.
- Knives incorrectly mounted.
- Worn or broken knives.
- Rotor misshapen owing to blows received during work from for-
eign bodies in the central part.
Other faults
The machine fails to work evenly along its length, shredding ei-
ther too much or too little on one side, for example on the right:
shorten the right link.
Work on hilly ground
Proceed “upwards” in the direction of the slope.
4.4 TINES
The knives with which the machine is equipped are suitable for
work with soil/plants of normal conformation. Check their condition
each day to make sure they are not worn. If them should
accidentally bend (or break) during work, they must be immedi-
ately replaced and mounted in the identical position.
DANGER
Tool replacement (knives) is a dangerous operation.
Proceed in the following way to replace the tools:
- Park the tractor on a flat surface with the machine hitched, then
raise the machine with the power lift;
- Insert two strong bearing stands at the sides of the machine;
- Lower the machine on to the stands, turn off the tractor engine
and apply the parking brake.
