GROOMING MOWER
OPERATOR’S MANUAL
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 operation, 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.

GROOMING MOWER
OPERATOR’S MANUAL
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
GM2 series, for tractors up to 50 HP, come in working widths of 5’, 6’ and 7’. The
mower can be either tractor front or rear mounted. 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 GM2 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, are 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. When 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.

GROOMING MOWER
OPERATOR’S MANUAL
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 feet 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 minimize 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.
21.When using a unit, a minimum 20% of tractor and equipment weight must be on
tractor front wheels. Without 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. When attaining a minimum 20% of
tractor and equipment weight on the front wheels, you must not exceed the ROPS
weight certification. Weigh the tractor and equipment. Do not guess or estimate!
22.Inspect the entire machine periodically2. 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 traveling 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 - Set Up
Notice to dealer: Pre-delivery setup and service including lubrication is the
responsibility of the authorized dealer. It is up to him to assure that the machine is in
perfect condition 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 Checklist3 prior to delivering the mower.
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 easily.
As mentioned above, all our grooming mowers may be either tractor front or rear
mounted. Changing our mowers from front mount to rear, or vice versa, can be easily
done at our authorized dealerships. This is accomplished by simply turning the three
point hitch and the gearbox 180 degrees .
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).
Be sure all wheel arms are adjusted equally. This is the only way to ensure a
completely uniform cut.

3.05 - Attaching to the Tractor
Unit may be used on tractors ranging from 20 to 50 HP equipped with a standard PTO
and category 1 three point hitch6. 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. Adjust tractor top link to allow the mower to follow the ground
contour and yet remain as level as possible when raised to 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.
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.

tractor engine or engaging PTO lever.
Lower mower to the ground with the tractor rock shaft control lever. With 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 set for a PTO speed of 540 rpm.
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. Worn or damaged blades should be changed

13.Checking area for stones, branches and other debris that might be thrown.
14.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. Under most conditions a 3 to 8 mph ground speed is best. As a rule of
thumb, and if the conditions permit, grass dispersion is increased by higher ground
speeds.
In order to obtain the best cut possible, always keep the tractor rpm up to the speed
indicated on the mower. When 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.
The mulching kit is an option available for our 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 pulverizes grass and leaves.
Another benefit of the mulching kit is safety. In fact, the kit greatly reduces the
possibility of thrown objects. This is particularly important when mowing around
schools, public parks and golf courses. If you are using a mulching kit, you need to
reduce your ground speed to under 2 mph (see fig. 6).

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.

GROOMING MOWER
OPERATOR’S MANUAL
5. Grass condition, wet or dry.
This mower has been designed to cut grass with heights from 4” to 8”. It is
recommended to avoid cutting grass taller than 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 grass can be cut at a faster ground speed. For cleaner
cuts and efficient mowing, the blades must be kept sharp9.
Always operate PTO at 540 rpm. 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 evenly, 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.
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.
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: 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 finishing 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
DANGER: Be careful of rollover when operating tractor and mower over uneven
ground.
The following precautions should always be observed when working on uneven terrain:
1. In extremely uneven terrain rear wheel weights, front tractor weights, and/or tire
ballast should be used to improve stability.
2. Observe the type of terrain and develop a safe working pattern.
3. Whenever traction or stability is doubtful, first test drive over the terrain with the PTO
disengaged.
4. Operate the implement 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.
5. Pass diagonally through sharp dips and avoid sharp drops to prevent hanging up the
tractor and implement.
6. Slow down on sharp turns and slopes to prevent tipping or loss of control.
7. Avoid tipping the mower while cutting.
8. Watch for holes, roots or other hidden objects. Do not use near the edge of a gully,
ditch or stream bank.
An anti-scalping roller is recommended for uneven ground contours. The roller
rides the nose of the mower over a mound to help keep the nose from bulldozing

CAUTION: Disengage tractor PTO. Set parking brake. Stop engine and remove
key from ignition. Disconnect mower driveline from tractor PTO shaft. Collapse
driveline and store in appropriate place. Disconnect three point linkage and
carefully drive tractor away from mower.
3.11 - Transport
Before raising the mower for transport, the tractor top link must be adjusted so when
lifted, the rear of the machine is higher than the front (the mower’s nose is tilted
downward). To do this, shorten the tractor top link until the top hitch plate is locked
forward and no longer able to pivot. This will keep the mower locked in position and
minimize the shaking and bouncing during transport which can damage the hitch or
frame.

GROOMING MOWER
OPERATOR’S MANUAL
When raising the mower be sure the PTO driveline does not hit either the mower or the
tractor. During transport the mower should not be lifted over 14”-16” from the ground.
CAUTION: Make sure PTO is disengaged and blades have stopped turning before
raising mower to full transport position.
Do not tow tractor and mower behind other vehicles. Use a properly equipped
trailer with heavy tie-downs for towing operations.
Before transporting:
1. Disengage PTO.
2. Shorten tractor top link until top hitch plate is locked.
3. Raise machine and lock rockshaft control lever.
4. Always select a safe ground speed that is appropriate for the terrain.
5. Beware of traffic on public roads. Install a SMV (Slow Moving Vehicle) sign when
traveling on roads or streets.
6. Reduce ground speed when turning and take care that the mower does not strike
obstacles such as trees, fences or buildings.
3.12 - Quick Hitch Adapter Assembly and Operation
Using a iMatch/Quick Hitch system: The GM20 series mowers can be used with a
Quick Hitch system, allowing for quick and easy hookup, by installing an optional
adapter. This optional adapter has floating yokes that will allow the mower to follow the
contour of the ground.
WARNING: When using a Quick Hitch on a PTO driven implement always ensure
there is the proper driveline overlap prior to use. If there is not the minimum 6”
driveline overlap do not use and contact your nearest dealer to purchase a longer
driveline.
Quick Hitch Adapter assembly (see fig. 7):
1. Remove lower hitch arms from grooming mower’s linking plates.
2. Remove bolt M16x140 on top of the three point hitch of the grooming mower.
3. Remove bolts M16x45 that hold the top hitch supports to the linking plates of the
mower.
4. Install the floating yokes of Quick Hitch Adapter assembly to the linking plates of the
mower using the hex bolts M16x65 and the stover nuts M16. Install the floating
yokes in the same hole that the hitch pins were mounted. NOTE: When installing
the quick hitch adapter on the GM2084, the floating yokes need to be installed
on the opposite side than the other models. Install the left yoke on the right
side and the right yoke on the left side of the mower (see fig. 8).
5. For proper operation of the mower, ensure that the floating yokes are parallel to the
ground.

Sharpening blades
Blade sharpening is extremely important in order to get the best cutting results. Sharp
blades permit a high quality cut and also reduce HP thus lowering cost.
To sharpen blades, first remove them following the above instructions.
Place the blade in a vise and sharpen them by using a hand file or grinder. Do not
sharpen the blades to a sharp cutting edge. The cutting edge should be between
1
1/64” to /32” to prevent excessive pitting and dulling of the blades. Sharpen both ends of
the blade equally for balance and always maintain corners. Always keep all three
blades sharpened equally in order to maintain balance.

DANGER: Only use the original driveline supplied with this mower and always
with the safety shielding. Carefully read and file away the driveline operator’s
manual supplied by the manufacturer. The following does not substitute the
information found in the driveline manual.
IMPORTANT: Always check driveline length during initial setup and when connecting to
a different tractor.
In the collapsed position the driveline should be approximately 2” from bottoming out to
prevent possible damage to the tractor or implement. When the driveline is in the
maximum extended position, the ideal minimum overlap of the two halves should be
approximately 6” (see fig. 16).

GROOMING MOWER
OPERATOR’S MANUAL
If determined that the driveline is too long , follow these procedures to adjust the length:
1. Separate the two driveline halves. Connect one half to the tractor PTO and the other
half to the mower.
2. Raise and lower the mower with the 3 point hitch to find the position where the
driveline is shortest. Hold the half shafts side by side and mark the desired length on
the outer female tube guard leaving a 1½” gap between the end of the guard tube
and bell guard.
3. Cut off both guard tubes the same amount as marked in step 2.
4. Shorten both drive tubes the same amount as guard tubes.
5. De-burr and clean filings from drive tubes and apply grease to outside of inner
telescoping tube.
6. Reassemble the driveline halves and connect to tractor and mower. Raise and lower
mower again to be sure driveline does not bottom out in its shortest position and has
a minimum overlap of 6” in the longest position.
7. Install both driveline safety chains. One should be hooked in a hole on the outer
driveline yoke shield and to the tractor to restrict outer shield rotation. The second
one should be hooked in a hole on the inner driveline yoke shield and to the
implement to restrict inner shield rotation.
If determined that the driveline is too short for your tractor, contact your local dealer.
