1.05 - Quick Hitch Adapter Assembly and Operation  
Using an iMatch/Quick Hitch system:  
The GM1 series mowers can be used with an iMatch/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 an iMatch/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” overlap do not use and contact your nearest dealer to purchase a  
longer driveline.  
iMatch/Quick Hitch Adapter assembly (see fig. 4):  
1. Remove hitch pins from grooming mower’s linking plates.  
2. Remove M16x140 bolt on top of the three point hitch of the grooming mower.  
3. Remove M20x45 bolts that hold the top hitch supports to the linking plates of the  
mower.  
4. Attach the floating yokes of quick hitch adapter assembly to the linking plates of the  
mower. Note: Two ½” long bushings for the floating yokes are provided in the  
hardware bag of the quick hitch adapter kit. Ensure these spacers are installed onto  
the M16x60 bolt.

5. Attach the floating top link to the top hitch arms using the M16x90 bolt and stover  
nut.  
6. Attach the A-frame support to the floating top link using the M16x110 bolt with stover  
nut.  
7. Install the M20x110 bolt with the 1-1/8” spacer into the A-frame support.  
8. Insert the M20x140 bolt into the floating yokes. The order should be as follows: bolt,  
first half of floating yoke, 1-3/8” bushing, A-frame support, M20 jam nut, second half  
of floating yoke, M20 stover nut. The two M20 jam nuts need to be jammed against  
each side of the linking plates of the grooming mower. This will allow some motion in  
the bushing.  
9. Loosen the M16x40 bolts that secure the top hitch arms to the rear support plates of  
the mower. Only loosen slightly. The arms must be able to move slightly up and  
down.  
10.Tighten all hardware, ensuring all bolts and nuts have enough play to allow quick  
hitch adapter to move up and down.  
Fig. 4 - Quick-Hitch Adapter assembly.  
iMatch/Quick Hitch adapter operation:  
After completing assembly of the adapter, the tractor lift arms should be raised and  
locked in a position so the floating yokes are horizontal. Ensure that the M16x60 bolt is  
approximately in the center of the slot on the floating yoke. Positioning the bolt in this  
location allows the mower to have maximum float both up and down.

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. 5).  
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.

GROOMING MOWERS  
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  
GM1 series, for tractors up to 30 HP, come in working widths of 4’, 5’ and 6’  
respectively. 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 grooming mowers 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. 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.

GROOMING MOWERS  
OPERATOR’S MANUAL  
5. 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.  
6. 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.  
7. Do not allow riders on the mower or tractor at any time. There is no safe place for  
riders.  
8. Do not operate unless all personnel, livestock and pets are several feet away to  
prevent injury by thrown objects.  
9. Before backing up, disengage the mower and look behind carefully.  
10.Install and secure all guards and shields before starting or operating.  
11.Keep hands, feet, hair and clothing away from moving parts.  
12.This rotary mower is designed for use only on tractors with 540 rpm power take off.  
13.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.  
14.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.  
15.Frequently check mower blades. They should be sharp, free of nicks and cracks and  
securely fastened.  
16.Stop mower immediately upon striking an obstruction. Turn engine off, remove key,  
inspect and repair any damage before resuming operation.  
17.Stay alert for holes, rocks and roots in the terrain and other hidden hazards. Keep  
away from drop-offs.  
18.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.  
19.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.  
20.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!  
21.Inspect the entire machine periodically2. Look for loose fasteners, worn or broken  
parts, and leaky or loose fittings.  
22.Use only the driveline supplied with the mower. Do not use it if it is missing any  
shield or safety protection.

GROOMING MOWERS  
OPERATOR’S MANUAL  
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 (see fig. 6 & 7).  
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.  
Fig. 8  
The cutting height is  
adjusted by moving the  
height adjustment spacers  
on the wheel yokes above or  
below the wheel arm.  
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. 8).  
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 2” under most circumstances should be avoided.  
The cutting height is adjustable from 1” to 4”.  
A front anti-scalp roller is also available upon request. This accessory is particularly  
helpful when cutting over uneven terrain.  
3.04 - Pre-Operational Check  
IMPORTANT: Check each of the following, carefully, prior to engaging the equipment:  
1. The spindle bearings have been greased.  
2. The belts for proper tension.  
3. The oil in the gearbox.  
4. The driveline cross and bearings have been greased.  
5. No wrappings or foreign objects are around the blades, belts or driveline.  
6. The blades are properly installed and the blade bolts properly torqued4.  
7. All hardware is tight.  
8. The tractor, to ensure correct direction of PTO and rpm speed.  
9. All safety shields and guards are in place and tightly attached.  
10.No people or animals are in the work area.  
11.When 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  
transmission 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  
Unit may be used on tractors ranging from 18 to 30 HP equipped with a standard PTO  
and category 1 three point hitch5. Never use this mower with tractors over 30 HP.

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.  
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 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.

GROOMING MOWERS  
OPERATOR’S MANUAL  
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  
before starting6.  
7. Checking to ensure that the cutting edge is the leading edge of the blade7.  
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 that the PTO shield, belt shields and all other shielding are on the  
machine and securely in place.  
12.Making sure the proper attire is worn. Avoiding loose fitting clothing which can  
become entangled. Wearing 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.  
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 the GM1 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. 9).

The mulching kit is an  
available option,  
consisting in 3  
multilevel cutting edge  
blades and add-on  
containment baffling  
which bolts to the  
underside of the mower  
deck, to mulch and  
pulverize grass and  
leaves.  
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 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 sharp8.  
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

GROOMING MOWERS  
OPERATOR’S MANUAL  
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.

GROOMING MOWERS  
OPERATOR’S MANUAL  
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  
or the blades from scalping the ground.  
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  
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.  
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. Always select a safe ground speed that is appropriate for the terrain.  
2. Beware of traffic on public roads. Install a SMV (Slow Moving Vehicle) sign when  
traveling on roads or streets. Comply with all federal, state and local laws.  
3. Reduce ground speed when turning and take care that the implement does not strike  
obstacles such as trees, fences or buildings.  
4. Always disengage PTO before raising the implement to transport position.  
5. When raising the mower be sure the PTO driveline does not hit either the mower or  
the tractor.  
6. During transport the mower should not be lifted over 14” to 16” from the ground.

Installing or removing blades  
If the mower blades need to be installed, do the following:  
1. The blade turns in a counter clockwise direction when viewed from the bottom of  
the deck. The cutting edge must be towards the direction of rotation. The lift wing of  
the blades is closest to the deck and the cutting edge away from it (see fig. 12).  
2. Install the cup washer (see fig. 12) over the blade bolt and secure the blade in place  
as described above.  
3. With a wrench, block the spindle and tighten the bolt to 103 lb. ft. (see fig. 13).

DANGER: Proper torque must be used when tightening the blade retaining bolt. If  
these safety precautions are not followed, the blade could come off during  
operation and be thrown hundreds of feet from the mower.  
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 1/64”  
1
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.

Belt tension adjustment  
The mower has an automatic belt tensioner. The tension is created by a spring  
connecting a tensioner pulley to a fixed hitch plate with 3 positions (see fig. 14). Upon  
delivery, the spring is located in the first position. When the belt stretches after use,  
adjust the tension by relocating the spring in the other two holes. If the belt has  
stretched to the point that the belt is not tight enough even in the last hole, then it is  
necessary to replace the belt.

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).

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.  
CAUTION: Always work with the driveline as straight as possible. This will  
prolong its life and that of its components. It is advised, not to work at an angle  
greater than 15 degrees.
