2 - SAFETY PRECAUTIONS
Safety is the primary concern in the design and manufacture of our products.
Unfortunately our efforts to provide safe equipment can be wiped out by a single
careless act of an operator.
In addition to the design and configuration of equipment, hazard control and accident
prevention are dependent upon the awareness, concern, prudence and proper training
of personnel involved in the operation, transport, maintenance and storage of
equipment.
It is the operator's responsibility to read and understand all safety and operating
instructions in the manual and to follow these.
Allow only properly trained personnel to operate the mower. Working with unfamiliar
equipment can lead to careless injuries. Read this manual, and the manual for your
tractor, before assembly or operating, to acquaint yourself with the machines. It is the
mower owner's responsibility, if this machine is used by any person other than yourself,
is loaned or rented, to make certain that the operator, prior to operating, reads and
understands the operator's manuals and is instructed in safe and proper use.
2.01 - Preparation
1. Before operating equipment read and understand the operator's manual and the
safety signs (see fig. 4).
2. Thoroughly inspect the implement before initial operation to assure that all
packaging materials, i.e., wires, bands, and tape have been removed.
3. Personal protection equipment including hard hat, safety glasses, safety shoes,
and gloves are recommended during assembly, installation, operation,
adjustment, maintaining and/or repairing the implement.
4. Operate the mower only with a tractor equipped with an approved
Roll-Over-Protective-System (ROPS). Always wear your seat belt. Serious injury
or even death could result from falling off the tractor.
5. Clear area to be cut of stones, branches or other debris that might be thrown,
causing injury or damage.
6. Operate only in daylight or good artificial light.
7. Ensure mower is properly mounted, adjusted and in good operating condition.
8. Ensure that all safety shielding and safety signs are properly installed and in
good condition.

2.02 - Starting and Stopping
1. Be sure that no one is near the machine prior to engaging or while the machine is
working.
2. Be sure the tractor is in "Neutral" before starting engine.
3. Mower operating power is supplied from tractor PTO. Refer to your tractor
manual for PTO engagement and disengagement instructions. Always operate
PTO at 540 rpm. Know how to stop the tractor and mower quickly in case of an
emergency.
4. When engaging PTO, the engine rpm should always be low. Once engaged and
ready to start cutting, raise PTO speed to 540 rpm and maintain throughout
cutting operation.
5. Check the tractor master shield over the PTO stub shaft. Make sure it is in good
condition and fastened securely to the tractor. Purchase a new shield if old shield
is damaged or missing.
6. After striking an obstacle, disengage the PTO, shut the tractor down and
thoroughly inspect for damage before restarting.
7. Never engage the PTO until the mower is in the down position and resting on the
ground. Never raise the mower until all blades have come to a complete stop.
2.03 - Messages and Signs
1. Read and adhere to all safety and operating decals on this machine (see fig. 4).
2. Before dismounting tractor: allow moving parts to stop, stop engine, set brake
and remove the key of unattended equipment.
3. Keep away from rotating blades and driveline.
4. Keep guards and shields in place and in good condition.
5. Do not mow with bystanders in area.
6. Allow no riders on tractor or mower.
7. Allow moving parts to stop before repair.

3 - OPERATION
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
grooming mower, for tractors up to 30 HP, come in working widths of 4’, 5' and 6'. The
mower can be either tractor front or rear mounted and is available in rear discharge. On
your mower, the tractor PTO transmits 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 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
aspect 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 feet from a rotary mower. Only
properly trained people should operate this machine.
4. 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
