Checking and Replacing Blades
It is advisable to replace all the blades at the same time to prevent the machine vibrating. When mounting
the new blades, make sure the cutting edges are positioned in the direction the rotor rotates in.
1.
Place the machine at a comfortable height and lock it in position with sufficient support to guarantee the operator’s
safety. Prevent the blade rotating by locking the shaft with a key (the shaft is designed for this with two flat areas im
-
mediately above the blade).
2. Using the key, unscrew the nut 1 and remove the blade.
3. Check the state of wear of the pin and the nut and, if necessary, replace them.
4. Mount the new blade, screw in the nut “1” fully and with force, keeping the shaft locked at the same time as de-
scribed above.
Storing the machine for long periods of time
1. Clean all dirt from the machine. Take particular care to remove any foreign bodies from the blades.
2.
Park the mower on a flat surface, in a sheltered place inaccessible to either children or animals in a stable position
to prevent it from moving (for this purpose it is advisable to stop the wheels with wedges or other suitable means), fall-
ing or being fitted over etc.
3. Check that the weight of the machine is not too heavy for the surface on which it rests
Disposing of the Machine
When scrapping the machine, the procedure to adopt is as follows: remember that it is almost completely made
of ferrous material. The only potentially polluting components on the machine are the lubricants. To prevent them
from polluting the environment, spread a waterproof tarpaulin on the ground, position the machine on this and then
drain out the lubricants, which must be collected in suitable containers. Now dismantle the machine, separating the
components in the following way:
Painted parts;
Ferrous parts;
Plastic parts;
Rubber parts.
Contact those companies that are legally authorised to dispose of such materials.
Trouble Shooting
Fault
Cause
Remedy
Leaves a streak of
uncut or partially cut
grass
Blades dull or bent
Replace blades
Carrier RPM too low
Use correct PTO speed
Field conditions are so wet that the tractor
tire is pushing grass into mud
Too wet to mow. Stop operation and wait until it
is drier
Ground speed too fast
Reduce ground speed by shifting to a lower gear
Grass is down from previous weather
conditions
Mow in only one direction
Possible build-up materials under mower
Clean mower
Blades mounted incorrectly (cutting edge
against direction rotation)
Change blades so that cutting edge is facing
correct rotation.
Material discharges
from mower unevenly;
bunches of material
along with swath
Material too high and too much material
Reduce ground speed but maintain 540rpm at
tractor PTO or make two passes over material.
Raise mower for the first pass and lower to
desired height for the second and cut a 90
degree angle to first pass
Grass wet
Allow grass to dry before mowing. Slow ground
speed of tractor but keep engine running at full
PTO rpm. Cutting lower will help
