You have purchased a three spindle mower designed especially for the mowing of
grassy areas where a highly professional cut is required without wasting time.
This mower is perfect for the maintenance of parks, private lawns, industrial parks,
airports, hospital grounds, schools, highways, golf courses, sport complexes, etc. The
C50 series, for tractors up to 50 HP, come in working widths of 120, 150, 180 and 210
cm. (4', 5', 6' & 7' respectively). The mower can be either tractor front or rear mounted
and is available in both rear and side discharge
2
. On your mower, the tractor PTO trans-
mits its power through a driveline to a speed multiplier gearbox. A pulley is attached to
the pinion gear shaft of the gearbox which, via high resistance belts, transmits power to
pulleys coupled to the three individual spindle shafts. Blades are secured to these
shafts which turn at a high blade tip speed to cut the grass.
Our C50 grooming mower comes equipped with 4 swivel wheels. Aside from regulating
the cutting height, the wheels are set in such a way as to allow the mower to follow the
contour of the terrain and give a precise, level cut even in undulating conditions.
3.01 - Operational Safety
CAUTION: our mowers are designed considering safety as the most important
target and are the safest available in today's market. Unfortunately, human
carelessness can override the safety features built into our machines. Injury
prevention and work safety, aside from the features on our mowers, is very much
due to the responsible use of the equipment. It must always be operated
prudently following with great care, the safety instructions laid out in this manual.
1. The use of this equipment is subject to certain hazards which cannot be
prevented by mechanical means or product design. All operators of this
equipment must read and understand this entire manual, paying particular
attention to safety and operating instructions, prior to using.
2. Do not operate the tractor and mower when you are tired, sick or when using
medication.
3. Keep all helpers and bystanders at least several meters from a rotary mower.
Only properly trained people should operate this machine.

The model C50-210RD is available only in the rear discharge version.

4. hen this machine is operated in populated areas where thrown objects could
injure persons or property, standard equipment safety chain shielding (which is
designed to reduce the possibility of thrown objects) must be installed.
5. The majority of accidents involve entanglements on the driveline, injury of
bystanders by objects thrown by the rotating blades, and operators being
knocked off the tractor by low hanging limbs and then being run over by the
mower. Accidents are most likely to occur with machines that are loaned or
rented to someone who has not read the operator's manual and is not familiar
with a rotary mower.
6. Always stop the tractor, set brake, shut off the tractor engine, remove the ignition
key, lower implement to the ground and allow mower blades to come to a
complete stop before dismounting tractor. Never leave equipment unattended
with the tractor running.
7. Never place hands or feet under mower with tractor engine running or before you
are sure all motion has stopped. Stay clear of all moving parts.
8. Do not allow riders on the mower or tractor at any time. There is no safe place for
riders.
9. Do not operate unless all personnel, livestock and pets are several meters away
to prevent injury by thrown objects.
10. Before backing up, disengage the mower and look behind carefully.
11. Install and secure all guards and shields before starting or operating.
12. Keep hands, feet, hair and clothing away from moving parts.
13. This rotary mower is designed for use only on tractors with 540 rpm power take
off

.
14. Never operate tractor and mower under trees with low hanging limbs. Operators
can be knocked off the tractor and then run over by the rotating blades.
15. The rotating parts of this machine have been designed and tested for rugged
use. However, they could fail upon impact with heavy, solid objects such as steel
guard rails and concrete abutments. Such impact could cause the broken objects
to be thrown outward at very high velocities. To reduce the possibility of property
damage, serious injury, or even death, never allow the cutting blades to contact
such obstacles.
16. Frequently check mower blades. They should be sharp, free of nicks and cracks
and securely fastened.
17. Stop mower immediately upon striking an obstruction. Turn engine off, remove
key, inspect and repair any damage before resuming operation.
18. Stay alert for holes, rocks and roots in the terrain and other hidden hazards.
Keep away from drop-offs.
19. Use extreme care and maintain minimum ground speed when transporting on
hillside, over rough ground and when operating close to ditches or fences. Be
careful when turning sharp corners.
20. Reduce speed on slopes and sharp turns to minimise tipping or loss of control.
Be careful when changing directions on slopes. Do not start or stop suddenly on
slopes. Avoid operation on steep slopes.

A version with PTO at 1000 rpm is available upon request.

21. hen using a unit, a minimum 20% of tractor and equipment weight must be on
tractor front wheels. ithout this weight, tractor could tip over, causing personal
injury or death. The weight may be attained with a front end loader, front wheel
weights, ballast in tires or front tractor weights. hen attaining a minimum 20%
of tractor and equipment weight on the front wheels, you must not exceed the
ROPS weight certification. eigh the tractor and equipment. Do not guess or
estimate!
22. Inspect the entire machine periodically

. Look for loose fasteners, worn or broken
parts, and leaky or loose fittings.
23. Use only the driveline supplied with the mower. Do not use it if it is missing any
shield or safety protection.
24. Pass diagonally through sharp dips and avoid sharp drops to prevent "hanging
up" tractor and mower.
25. Avoid sudden starts and stops while travelling up or downhill.
26. Always cut down slopes; never across the face. Avoid operation on steep slopes.
Slow down on sharp turns and slopes to prevent tipping and or loss of control.
3.02 - Setup
Notice to dealer: pre-delivery setup and service including lubrication is the responsibil-
ity of the authorised dealer. It is up to him to assure that the machine is in perfect condi-
tion and ready to be used. It is his responsibility to ensure that the customer is aware of
all safety aspects and operational procedures for the mower. He must also fill out the
Pre-delivery checklist
5
prior to delivering the mower.

mower, front mounted.

CAUTION: stand clear of bands when cutting as they could be under sufficient
tension to cause them to fly loose. Take care in removing bands and wire, they
often have extremely sharp edges and cut very easy.
As mentioned above all our grooming mowers may be either tractor front or rear
mounted. To change our mowers from front mount to rear, or vice versa, it can easily be
done at our authorised dealerships. This is accomplished by simply turning the three
point hitch and the gearbox 180 degrees (see fig. 3 & 4).
3.03 - Cutting Height Adjustment
WARNING: keep hands and feet away from moving blades.
Be sure tractor engine is off, parking brake is locked, and key is removed before
making any adjustments.
Never rely on the tractor lift system. Install blocks or stands under the mower
deck to prevent it from falling.
The cutting height is the distance from the blades to the ground. The cutting height is
adjusted by moving the spacers on the wheel yokes. Placing spacers between the
wheel arm and the wheel yoke raises the cutting height by the size of the spacer.
Removing the spacers, lowers it by the same height (see fig. 5).
CYCLONE 'C50' OPERATOR'S MANUAL
SAFETY PRECAUTIONS 13 ROTOMEC
Fig. 4

Be sure all wheel arms are adjusted equally. This is the only way to ensure a
completely uniform cut.
IMPORTANT: very low cutting heights should be avoided. Damaging shock loads
occur when the blades strike the ground repeatedly. This can cause damage to
the mower.
Cutting lower than 5 cm. (2") under most circumstances should be avoided.
The cutting height is adjustable from 25 to 125 mm. (1" to 5").
A front anti-scalp roller is also available upon request
6
. This accessory is particularly
helpful when cutting over uneven terrain.
3.04 - Pre-Operational Check

11. hen working, make sure the tractor hitch is in the "float" position, in order to
allow the mower to follow the contour of the ground.
DANGER: stay clear of rotating driveline. Entanglement in rotating driveline can
cause serious injury. Disengage PTO, engage parking brake or place transmis-
sion in "Park", shut off the tractor and remove the key before working around
hitch, attaching or detaching driveline, making adjustments, servicing or cleaning
the machine.
3.05 - Attaching to the Tractor
Only use this model implement with tractors in the correct power range
8
. Never use this
mower with tractors over 50 HP.
CAUTION: check the tractor PTO rpm to ensure it is set at 540 and turns
clockwise.
CAUTION: always ensure that the tractor tire pressure is correct according to the
tractor operator's manual.
DANGER: failure to ensure a secure coupling of the implement to the tractor can
cause injury and damage to the implement or tractor.
To attach the mower to the tractor do the following:
1. back the tractor up to the mower in order to slip the tractor hitch arms over the
hitch pins welded to the mower hitch arms. Turn off the tractor engine. Secure
them in place with the lynch pins.
2. Adjust the tractor sway blocks or chains to remove all side movement.
3. Attach the top link secure it in place with the top hitch pin. Adjust tractor top link
to allow the mower to follow the ground contour and yet remain as level as
possible when raised to the transport position.
4. Install the shielded driveline to the tractor by first lining up the splines and
depressing the snap pin. Push the yoke onto the PTO shaft as far as it will go.
Release the pin and pull back slowly until the pin clicks in place. Repeat this
operation on the implement end.

See table 2, page 29.

5. Attach the driveline chains to the tractor and to the mower to keep the driveline
protection from turning. The chains should not be too tight.
3.06 - Start Up
DANGER: the mower must always be lowered to the ground before starting
tractor engine or engaging PTO lever.
Lower mower to the ground with the tractor rockshaft control lever. ith the engine
idling, slowly engage the PTO drive. Move the throttle lever until the PTO speed
indicated on the mower is obtained.
The mower is normally set for a PTO speed of 540 rpm
9
.
Shift the transmission to a slow speed gear and start forward, increase the ground
speed by shifting upward until the desired speed is obtained. Do not mow in reverse
unless absolutely necessary and only after careful observation of the area behind the
mower.
CAUTION: do not operate this mower at a PTO speed or direction of rotation other
than that shown on the mower. Serious damage can occur to the machine and/or
the operator.
Before starting to mow, never forget that the operator is responsible for the following:
1. safe and correct driving of the tractor and mower.
2. To learn precise, safe operating procedures for both the tractor and the mower.
3. To ensure all maintenance and lubrication has been performed on the mower.
4. To have read and understood all safety aspects for the mower in the operator's
manual.
5. To have read and understood all safety decals on the mower.
6. Checking the condition of the blades. orn or damaged blades should be
changed before starting
10
.
7. Checking to ensure that the cutting edge is the leading edge of the blade
11
.
8. Checking that there is no wire, weed, grass or other material wrapped around
blades.
9. Checking to see, if front weights need to be added to the tractor in order to
maintain balance.

10. Checking the tractor tires for the proper pressure in accordance with the tractor
operator's manual.
11. Checking the side discharge chute (on side discharge mowers only) to ensure
that it is properly in place.
12. Checking that the PTO shield, belt shields and all other shielding are on the
machine and securely in place.
13. Making sure the proper attire is worn. Avoiding loose fitting clothing which can
become entangled. earing sturdy, tough-soled work shoes and protective
equipment for eyes, hands, ears and head. Never operate tractor or implements
in bare feet, sandals or sneakers.
14. Checking area for stones, branches and other debris that might be thrown.
15. Ensuring proper lighting is available, sunlight or good artificial lighting.
3.07 - Working Speed
The mowing speed depends on ground conditions, tractor HP, mowing height and grass
thickness. Only a test run will enable you to gauge the optimal working speed for your
conditions.
CYCLONE 'C50' OPERATOR'S MANUAL
SAFETY PRECAUTIONS 17 ROTOMEC
Fig. 6
The mulching kit is
an option available
for the rear discharge
mowers.
This kit, containing
3 multilevel cutting
edge blades and
add-ons containment
baffling which bolts
to the underside of
the mower deck,
mulches and
pulverizes grass
and leaves.

Under most conditions a 6 to 12 km per hour (4 to 7 mph) ground speed is best. As a
rule of thumb, and if the conditions permit, grass dispersion is increased by higher
ground speeds. This is true for both rear and side discharge models.
If you are using a rear discharge mower with a mulching kit (see fig. 6), you need to
reduce your ground speed to under 4 km per hour (2 mph).
The mulching kit is an optional kit available for the rear discharge mowers. This kit
containing 3 multilevel cutting edge blades and add-on containment baffling which bolts
to the underside of the mower deck, mulches and pulverises grass and leaves.
Another benefit of the mulching kit, is safety. In fact, the kit greatly reduces the possibil-
ity of thrown objects. This is particularly important when mowing around schools, public
parks and golf courses.
In order to obtain the best cut possible, always keep the tractor rpm up to the speed
indicated on the mower. hen increasing or decreasing mowing ground speed, always
use gear selection, not engine speed. This will maintain the constant maximum blade
speed necessary for a clean cut.
3.08 - Operating Techniques
All of the following factors are important in selecting the proper forward speed:
1. height of grass.
2. Type of grass.
3. Density of grass.
4. Type of terrain.
5. Grass condition, wet or dry.
This mower has been designed to cut grass with heights from 10 to 20 cm. (4" to 8"). It
is recommended to avoid cutting grass taller than 25 cm. (10").
For the best results, try cutting the grass at least once per week during growing season.
Tall, dense grass should be cut at low speed, while thin medium material can be cut at
a faster ground speed. For cleaner cuts and more efficient mowing the blades must be
kept sharp
12
.
Always operate PTO at 540 rpm
13
. This is necessary to maintain proper blade speed
and obtain a clean cut.
Under certain conditions, tractor tires may roll some grass down and prevent it from
being cut at the same height as the surrounding area. If this occurs reduce the tractor
ground speed but maintain a 540 rpm engine speed. The lower ground speed will
permit the grass to at least partially rebound. Under some conditions grass will not
rebound enough to be cut even, resulting in an uneven appearance. In general, lower
cutting height gives a more even cut with less tendency to leave tire tracks. If cut is still
not satisfactory, cut the area twice.
OPERATOR'S MANUAL CYCLONE 'C50'
ROTOMEC 18 GENERAL INFORMATION
13
A version with PTO at 1000 rpm is available upon request.
12
See Sharpening Blades in section 4.03 - Blade Maintenance.

Mow extremely tall grass twice. On the first pass use a high cutting height. On the
second pass position the mower at the desired height and when practical, mow at a
right angle in travel to the first pass.
Plan your pattern to travel straight forward whenever possible.
It is better to cut grass more often, than too short. Short grass deteriorates rapidly in hot
weather and invites weed growth during growing season.
hen using the side discharge model, operate the mower with uncut grass to the left.
Clippings will discharge over the cut area. Continued discharging of clippings over the
uncut area could result in the build up of clippings.
If at any time the mower should jam resulting in belt slippage of 2 or more seconds,
raise the mower and continue for 2-3 minutes. This will allow the pulleys to cool and
prolong belt life.
DANGER: never operate the mower without the discharge deflector on side
discharge models properly installed (see #1, fig. 7). The mower blades can throw
objects hundreds of feet which could result in personal or property damage.
Pick up all rocks and other debris before mowing.
Enter new areas carefully. Cut grass higher at first, allowing mower to clear
hidden objects.
CAUTION: for emergency reasons learn how to stop the tractor and mower
quickly. On the Cyclone mowers always disengage the PTO, lock parking brake,

stop engine and allow the mower blades to come to a complete stop before
dismounting the tractor.
3.09 - Uneven Terrain
WARNING: be careful of roll-over when operating tractor and mower over uneven
ground.
In extremely uneven terrain rear wheel weights, front tractor weights, and/or tire ballast
should be used to improve stability.
hen mowing over uneven terrain, observe the type of terrain and develop a safe
mowing pattern. henever traction or stability is doubtful, first test drive over the terrain
with the PTO disengaged.
Operate the mower up and down steep slopes, not across slopes, to prevent the tractor
from tipping. Avoid sudden stops and starts, and slow down before changing directions
on a slope.
Pass diagonally through sharp dips and avoid sharp drops to prevent hanging up the
tractor and mower.
Slow down on sharp turns and slopes to prevent tipping or loss of control.
Avoid tipping the mower while cutting. atch for holes, roots or other hidden objects.
Do not cut near the edge of a gully, ditch or stream bank.
3.10 - Removing Mower from the Tractor
CAUTION: disengage tractor PTO. Set parking brake. Stop engine and remove key
from ignition. Disconnect mower driveline from tractor PTO shaft. Collapse drive-
line and secure it in place with the storage hook on the mower three point.
Disconnect three point linkage and carefully drive tractor away from mower.
