from under the mower deck at high speeds, up to 300 ft away.
Objects ejected by the mower blades can cause severe injury.

Never tamper with safety devices or operate the mower with
them removed. Check proper operation regularly.

Always disengage PTO, place all controls in neutral, turn power
unit off, set parking brake, and remove key before dismounting,
for any reason.

Never place hands or feet under mower deck when the mower
is operating or power unit engine is running.

Disengage the PTO when crossing gravel areas or roadways.

Disengage the PTO and turn power unit off upon striking any
object. Inspect mower and repair any damage before
continuing.

If the equipment should start to vibrate abnormally during
operation, stop the mower, shut down power unit, and
immediately check for the cause. Excess vibration is generally
an indication of a problem. Replace bent or damaged parts, do
not attempt to straighten a bent blade.

Use extreme care when operating on uneven terrain.

Reduce speed when operating on slopes during wet conditions,
especially when making sharp turns.

Do not use the mower in limited visibility (e.g. at dusk, in fog,
heavy rain etc.). Mow only in daylight or good artificial light.

Disengage PTO and ensure blades are completely stopped
before raising wings.

Ensure wing and deck safety locks are securely engaged
before transporting mower with wings in raised position.
10
Pro-Flex 120 Series Operator’s Manual

Mower is not intended for transport on public roadways.

Before disconnecting from power unit, always lower equipment
to the ground, place controls in neutral, set park brake, turn
engine off, and wait for all moving parts to stop. Relieve
hydraulic pressure per power unit manufacturer’s instructions.

Ensure mower tongue jack is securely fastened to mower frame
with supplied pin before removing hitch draw pin.
MAINTENANCE SAFETY PRECAUTIONS

Never make adjustments or repairs with the engine running.
Always disengage PTO, engage parking brake, turn engine off,
lower wings to cutting position and relieve hydraulic pressure
before performing any maintenance.

Observe and perform proper lock-out procedures for power unit
if attached to mower during service.

Keep nuts and bolts tight and properly at the proper torque,
especially blade attachment bolts. Check that all cotter pins are
properly installed. Keep equipment in good condition.

Keep mower free of grass, leaves, or other debris build-up.

Never work on raised mower decks without safety locks in
place.

Periodically check condition of safety devices, guards, and
deflectors. Replace only with manufacturer’s recommended
parts.

Inspect and replace damaged blades. Use only original OEM
parts. Blades can fail from poor maintenance practices.

Handle mower blades carefully. They are sharp and can cut
unprotected skin. Use caution and wear gloves when handling
them.

Check to make sure hydraulic hoses are not worn or damaged,
and are routed to avoid chafing.

Immediately replace any hydraulic hose that shows signs of
swelling, wear, leaks or damage so it does not burst.

Do not use your hand to check for hydraulic oil leaks. Use a
piece of cardboard instead. Hydraulic fluid escaping under
pressure can penetrate the skin causing serious injury. If skin
penetration occurs, seek medical attention immediately. Relieve
all pressure before disconnecting hoses.

Do not bend or strike hydraulic lines, tubes or hoses, or reinstall
them in a bent or damaged condition.

Inspect tires daily for wear or damage. Check tire pressures
weekly with an accurate pressure gauge. Do not inflate tires
beyond 35 psi.

Mounting and dismounting tires from rims can be dangerous
and should be performed by trained personnel using correct
tools, equipment and procedures.
11
Pro-Flex 120 Series Operator’s Manual

Do not support the machine on cinder blocks, hollow tiles or
other members that may fail under continuous load.

Never perform service on a machine that is supported solely by
a jack. Always ensure proper blocking is placed to support load
during service.
WELDING / GRINDING WORK PRECAUTIONS
IMPORTANT! A fire extinguisher should be easily accessible
during all welding work.
Welding repairs are to be performed by a trained welder with proper
service instructions. Know the material to be welded and select the
correct welding procedure and materials (electrodes, rods, wire) that
will provide a weld metal strength equivalent to the parent material.
Move the machine to a clean, safe area before welding, grinding or
using a cutting torch on it. This type of work should only be done in a
clean area and not in places that contain combustible liquids, such as
fuel tanks, hydraulic pipes or similar.
Connect arc welder ground as close as possible to work area.
Work with extra care when welding, grinding or torch cutting near
flammable objects.
WORKING ON PAINTED SURFACES
Heated paint gives off poisonous gases. Therefore, paint must be
removed from an area with a radius of at least 4 in (10 cm) before
carrying out welding, grinding, or gas cutting. In addition to the health
hazard, the weld will be of inferior quality and strength if the paint is
not removed.
Methods and precautionary measures when removing paint:
Blasting – use respiratory protective equipment and protective
goggles.
Paint remover or other chemicals – use a portable air
extractor, respiratory protective equipment, and protective
gloves.
Grinding – use a portable air extractor, respiratory protective
equipment, and protective gloves and goggles.
WORKING ON GALVANIZED / PLATED SURFACES
Only qualified welders should attempt a weld repair on galvanized or
plated components.
Proper pre-welding surface preparation is
required.
Always ensure proper ventilation, wear proper respiratory protective
equipment and avoid direct contact with smoke emitted from welding
process.
12
Pro-Flex 120 Series Operator’s Manual
HYDRAULIC SYSTEM SERVICE PRECAUTIONS
Risk of personal injury! Wear safety
glasses and use protective gloves.
Relieve all trapped pressure before performing any service to the
hydraulic system. Pressure can be maintained in the hydraulic circuits
long after the power source and pump have been shut down.
When servicing any hydraulic component of the mower ensure that all
decks and wings are in their lowered position and all hydraulic
pressure is relieved.
Tighten all connections before applying pressure.
It is important that each person who comes in contact with the
machine be alert to any faults.
Follow these basic precautions:

Never adjust a pressure relief valve or other pressure-limiting
device to a higher pressure than specified.

Check to make sure hydraulic hoses are not worn or damaged,
and are routed to avoid chafing.

When connecting mower to tractor ensure hydraulic hoses have
sufficient slack for negotiating turns and uneven terrain.

Immediately replace any hydraulic hose that shows signs of
swelling, wear, leaks or damage so it does not burst.

Do not use your hand to check for hydraulic oil leaks. Use a
piece of cardboard instead. Hydraulic fluid escaping under
pressure can penetrate the skin causing serious injury. If skin
penetration occurs, seek medical attention immediately. Relieve
all pressure before disconnecting hoses.

Do not bend or strike high-pressure lines, tubes or hoses, or
reinstall them in a bent or damaged condition.
HYDRAULIC OIL HANDLING PRECAUTIONS
Oils can irritate and damage the eyes, throat, and sensitive skin.
Avoid contact.
Petroleum based oils are hazardous to the environment. Take special
care not to spill or discharge these fluids. Use approved containers
and methods to handle and dispose of them.
Use an authorized disposal and recycling company.

ASSEMBLY INSTRUCTIONS
Mower assembly must be completed by a qualified technician using
safe work practices and proper tools.
REAR MOWER DECK
The center rear mower deck, lift arm and drive belt are placed on a temporary rack for shipping
purposes. The RH wing deck can be used as an assembly reference.
1. Remove the deck and the lift arm assembly from the rack. A chain hoist or lift truck and straps
will be necessary (deck assembly weight – approx. 250lb).
2. Remove both of the center shields of the main drivetrain by extracting (8) 3/8” bolts in order to
install deck drive belt on to the gearbox.
3. Remove (2) 5/8” bolts and bushings that are installed in the lift arm yoke mounts.
4. Roll the deck assembly into position at the center-rear of the mower and remove the rear deck
shields by extracting (2) 3/8” X 3 3/4” bolts.
5. The rear deck belt is then installed by starting at the drive pulley (rear of gearbox), down behind
the frame and twisting it 1/4 turn to ride on the idlers (both fixed and moveable) and then onto
the deck spindle pulley
6. Position the lift arm so that the 5/8” bolt and bushings can be attached to the frame. Some
alignment of the deck will be necessary to thread both bolts into the frame.
7. Attach hydraulic hoses to a hydraulic power source. Stroke the center cylinder out completely.
Remove the cylinder pin by loosening the 3/8” bolt that holds it in place. Relieve any residual
hydraulic pressure and disconnect from power source.
8. The rod end bushing is placed between the slotted plates on the lift arm. Push the pin through
one slot, through the bushing and through the other slot. Tighten the bolt being sure the bolt
end rests in the indent in the pin at its center. .The pin is now locked in place.
9. The shock absorber is then installed in the threaded hole located on the side of the lift arm near
where the end of the shock rests. Use the fasteners shipped on the loose end of the shock.
10. Re-install the shields on the main drive train and the center deck.
11. There are two rectangular plastic plugs taped to the frame of the mower. They serve to fill the
tube ends on the frame where the temporary transport frame was installed.
INPUT SHAFT – shipped strapped to center rear mower deck (on transport rack)
1. Remove ½” UNC retaining bolt/nut from input shaft.
2. Remove notification tag from intermediate shaft hanger bearing.
IMPORTANT - Ensure gold coloured spacer ring is present against bearing inner race.
3. Disconnect input shaft shield at clamp yoke end and slide shield exposing the clamp yoke (see
input shaft service instructions in mower manual storage tube).
4. Install input shaft clamp yoke on intermediate shaft, ensuring gold coloured spacer ring is in
place between the input shaft yoke and hanger bearing race.
5. Reinstall ½” UNF retaining bolt in input shaft yoke, torque to 85 ft-lb.
6. Reinstall input shaft shield per input shaft service instructions.
7. Fasten input shaft guard retaining chain to mower main frame.
TRANSPORT TIRES

Pro-Flex 120 Series Operator’s Manual
MOWER SETUP FOR OPERATION
Always refer to tractor operator’s manual for specific detailed
information regarding operation of equipment.
Always ensure the tractor controls are in the park position, the
engine is turned off, the parking brake is engaged and hydraulic
pressure to the tractor remote connectors has been relieved
when working around tractor during setup procedures.
HITCH ADJUSTMENT
Before hitching the mower to the tractor, ensure tractor drawbar is set
properly. Having the proper hitching dimensions for the tractor
drawbar and the PTO, will ensure long and trouble free hours of
operation. Incorrect setup may lead to contact between the
mower and PTO shaft, causing damage to the shaft.
The decal shown is mounted to the machine and indicates these
important hitch dimensions.
1) The drawbar length must be adjusted so it is 14” to 15” from
the end of the PTO shaft to the center of the draw pin.
2) The top of the drawbar must be adjusted so it is 6” to 9” from
the center of the PTO shaft to the top of the drawbar.
DRAW
CLEVIS
CLEVIS MTG.
BRACKET
3) The main frame of the mower should be level when hitched to
the tractor. The Pro-Flex 120 features an adjustable height
hitch; the above figure shows the pivoting Draw Clevis and
bolt-on Clevis Mounting Bracket that can be turned to give a
total of 3” in height adjustment.
4) The position of the hose support and hose guide rod may
need to be adjusted to provide clearance to the PTO shaft.
5) To assist in connecting the Pro Flex 120 to the tractor, the
provided hitch pin can be temporarily placed in the hitch
swivel to hold it level while aligning the hitch. Do not operate
mower with the hitch pin in the hitch swivel.
17
Pro-Flex 120 Series Operator’s Manual
HITCHING THE MOWER TO THE TRACTOR
Crushing Hazard between tractor and mower. Never allow
anyone to stand between tractor and mower while backing-up to
the mower
1) With the draw pin placed in the hitch clevis, back the tractor to
the hitch clevis.
2) When the draw pin holes are aligned, place the tractor
controls in the park position, shut the engine off and engage
the parking brake.
3) Remove draw pin from the hitch clevis and place in the draw
pin hole connecting the mower to the tractor.
4) Raise parking jack fully and place in storage position.
STOWING THE JACK
The jack cannot be stowed in the parked position while mowing. A
second storage position is provided along the frame of the mower to
avoid damage to the jack while mowing (shown at right).
CONNECTING THE TRACTOR PTO
1) Ensure that the tractor engine is shut off, the parking brake is
engaged and the mower is securely hitched to the tractor.
2) Lift input PTO shaft from PTO support, ensuring that PTO
support swings down and rests on frame tube.
3) Slide the mower input shaft locking collar backwards, opening
the locking mechanism. Locking collar should remain in an
open position
4) When it is safe to do so, hold the PTO against the end of the
tractor PTO shaft, rotate the tractor PTO by hand until the
shaft slides on slightly.
5) Slide the yoke onto the tractor’s PTO.
6) The locking collar should automatically engage when the
yoke is properly engaged with the tractor PTO.
7) Attempt to move the shaft forward and backwards to ensure
that it is securely locked in place.
8) Attach the PTO cover safety chain to the tractor. Ensure
cover is properly retained by the chain on the mower end.
If the PTO shaft comes off during operation, it may cause
personal injury and damage to the PTO shaft and tractor PTO.
When checking, make sure the locking collar is locked, and that
the shaft is not just jammed against the end of the tractor PTO
shaft.

Pro-Flex 120 Series Operator’s Manual
CONNECTING THE HYDRAULICS
1) Ensure the tractor controls are in the park position, the engine is
turned off, the parking brake is engaged and hydraulic pressure
to the tractor remote connectors has been relieved per the
tractor operator’s manual instructions.
2) When connecting the hydraulic couplers to the tractor, be sure
that both ends are clean. Dirt in the hydraulic system can block
the orifice in the cylinder and cause premature wear of hydraulic
components on the mower and tractor.
3) Ensure the hoses are free to move, between the tractor and
mower. During operation of the mower the distance between
the tractor and mower will change while going up and down hills
or during turns.
Hydraulic fluid escaping under pressure can penetrate the skin
causing serious injury. If skin penetration occurs, seek medical
attention immediately.
CONNECTING THE PULL ROPE
The Pro-Flex 120 mower is equipped with a nylon pull rope that is
connected to the wing deck release mechanism, used for locking the
two outside wings into transport position.
Connect it to the tractor in a position that is easily accessible to the
operator and will release easily if the mower should ever become
disconnected. Ensure there is sufficient slack between the tractor and
mower to allow for proper maneuvering of machine without rope
becoming entangled.
MOWER SAFETY LOCKS
Safety locks are provided on the wings as well as each individual
mower deck to prevent each from lowering in the event of a failure in
the hydraulic system.
WING SAFETY LOCK
(2) spring activated wing safety locks are located behind the deck
drive train, one for each wing. The lock is engaged automatically
when the wings are raised.
In order to lower the wings:
1) Fully raise the wings (they may have settled against the lock
during transport or storage).
2) From the operator station in the tractor, pull and hold the pull
rope to disengage the locks.
3) Lower the wings to the working position using the tractor
hydraulic control (keeping rope pulled).
4) Release the pull rope when the wings are lowered.
19
Pro-Flex 120 Series Operator’s Manual
DECK SAFETY LOCK
Each deck is provided with individual safety locks. These locks have
(2) modes of operation:
TRANSPORT / SERVICE POSITION
1) Ensure the tractor controls are in the park position, the engine
is turned off, the parking brake is engaged.
2) On each deck, pull the silver coloured mowing position tab and
rotate upward until the round pin is above the top of the lock
bar.
3) When all (5) deck locks have the tab in this position, fully raise
mower decks.
4) Locking mechanism will engage automatically preventing decks
from lowering.
MOWING POSITION
1) Fully raise decks using tractor hydraulics (deck cylinders fully
retracted)
2) Ensure the tractor controls are in the park position, the engine
is turned off, the parking brake is engaged
3) On each deck, lift the lock bar, pull the silver coloured mowing
position tab and rotate downward until the round pin is engaged
in the corresponding hole in the lock bar. (The tab in this
position prevents the deck safety lock from engaging during
mowing)

Ensure mowing position tabs are in the Transport / Service
position and locks are properly engaged before attempting to
transport or service mower.
20
Pro-Flex 120 Series Operator’s Manual
CHECK PTO LENGTH - TURNING AND ON HILLS
The Pro-Flex 120 mower is designed for mowing of uneven,
contoured landscape. When negotiating turns, the input PTO shaft
will change in length. During mowing of steep contoured conditions,
when the tractor starts up a hill the PTO shaft will collapse and when
cresting the hill, it will extend. It is important to make sure that the
PTO shaft does not fully collapse, fully extend or contact the hose
shield or hose support rod during turns or when travelling over hills.
To ensure proper setup check the following conditions:
1) With the tractor in the lowest gear and travelling very slowly,
make a sharp turn to the right.
2) 2) Watch the PTO shielding to make sure the PTO shaft does
not totally collapse. There should be a minimum of 9 ½” of the
inner black PTO shielding exposed at maximum turn.
3) 3) Ensure PTO shielding does not come in contact with hose
support or hose support rod.
NOTE: This is not the worst condition. Making turns while the tractor
is angling up a hill will cause the PTO shaft to collapse even more.
Likewise, traveling straight up or down a hill will either extend of
collapse the PTO shaft. The operator should avoid making sharp
turns on uneven terrain.
If the PTO over extends, it will come apart and can cause injury
to the operator or damage to the mower or tractor.
If the input PTO shaft collapses fully, it will force the shaft back
against the hanger bearing. This will cause damage and
premature failure of the bearing.
CHECK TIRE CONTACT DURING TURNS
The Pro-Flex 120 mower features a hose support which also serves
the function to limit the steering angle of the mower without damage
to components. In proper operation, the tractor tire should contact the
hose support first if the operator attempts to turn too sharp without
damage to the drive-line.
To check tire contact:
1) With the tractor in the lowest gear and travelling very slowly,
make a sharp turn.
2) As you turn, watch closely to make sure the tractor tires contact
the hose support. (not other parts of the mower)
3) If the tires do not contact the hose support, adjust tractor tire
width (if possible), so they contact the hose support. Contact us
for a modified guard.
NOTE: Using this setup, with the proper adjustment, the tire will
contact the hose support and will not allow the tractor to turn
any further. This guard is not designed to work with lug style
tires.
21
Pro-Flex 120 Series Operator’s Manual
DISCONNECTING THE MOWER
The mower can be stored with the wings/decks in the raised or
lowered position. If the wings or decks are in the raised position,
ensure the wing and deck locks are securely engaged before
disconnecting the mower from the tractor.
1) Place mower on a level surface for storage.
2) Ensure that the tractor engine is shut off and the parking brake
is engaged.
3) Inspect wing / deck safety locks to ensure they are properly
engaged (if in the raised position).
A
4) While pulling on the lock release rope; relieve pressure in the
hydraulic hoses per tractor manufacturer’s instructions
(normally cycling the tractor control valve in both directions is
sufficient).
5) Chock mower transport tires to ensure mower does not roll
unexpectedly when hitch pin is removed.
6) Disconnect pull rope from rear of tractor and hook on hose
support rod.
7) Disconnect hydraulic couplers from tractor & stow in supplied
locations in the sides of the tire guard (position A as shown).
8) Disconnect input shaft guard chain from tractor. Slide the
mower input shaft locking collar backwards, opening the locking
mechanism. Locking collar should remain in an open position.
9) Remove input shaft from tractor (collapsing sliding shaft) and
stow on supplied support bracket (position B as shown).
10) Remove the tongue jack from the storage location and place in
the parking position. Raise the jack sufficiently to remove all
mower weight from the tractor drawbar. Ensure mower tongue
jack is securely fastened to mower frame with supplied pin
before removing hitch draw pin
11) Remove supplied draw pin from hitch and stow in the hitch
swivel.
LONG-TERM STORAGE
If the mower will not be used for an extended period, certain activities
must be performed. See “Long-Term Storage” in the Maintenance
section (Page 40).

ADJUSTING THE MOWER FOR CUTTING
Ensure safety locks are properly engaged before attempting to
service mower. Make all adjustments with the tractor turned off,
key removed and parking brake set. Mower must be on level
ground before making adjustments.
SETTING CUTTING HEIGHT
Each of the five independent mower decks has its own cutting height
adjustment. Cutting height is set by adjusting the height of the mower
deck wheel arms. Each deck has one fixed wheel arm and one
pivoting wheel arm; ensuring that all four tires remain in contact with
the turf while navigating contoured areas for a more uniform cut.
NOTE: For optimal cutting results, the mower should be set to
remove not more than 1/3 of the total grass height. This will
result in the best cutting performance while minimizing stress
to the grass.
The deck wheel arms are bolted solid to the deck frame in order to
provide positive cutting height control.
Follow these steps to adjust the cutting height from 3/4” to 3”:
1) Place the mower deck safety latch into the locking position on
each deck (See Page 19).
TM
2) Raise the mower decks into the Pro Lift-N-Turn
raised
position (See Page 27).
3) Turn the engine off on the tractor, place all controls in neutral
position and set the parking brake.
4) Using the cutting height decal, determine the hole you wish to
set the axles in according to the desired cutting height.
5) On the fixed arm side, remove the two mounting bolts and
reposition the axle in the desired holes. Be sure to retighten
properly.
23
Pro-Flex 120 Series Operator’s Manual
On the pivoting arm side remove the two axle stop pins and the
center pivot bolt. Reposition the axle to the proper hole for the
desired cutting height. Retighten the center pivoting bolt
properly.
6) Replace the two axle stop pins to the same hole in the pattern
as the axle mounting bolts. This pin is used to limit the travel of
the mower deck and prevent scalping. The pins are not required
for cutting heights of 2 3/4” and 3”. Store pins in one of the
holes for the center pivoting bolt.
SETTING THE DISCHARGE DEFLECTORS
Each mower deck has its own discharge deflector. This is a two
position deflector that can be adjusted by moving the spring clip on
the deflector. When set in the lower position it deflects the cuttings
downwards into the grass, and when set in the upper position, the
discharge fans out more discharging the cuttings straight out.
NOTE: In wet or heavy conditions, the deflector can be set in the
upper most position to help avoid clumping.
WING FRAME ALIGNMENT
When the wings are in the lowered position, the wing frame should be
level with the mower frame (this is pre-set at the factory). A stop bolt
is located on the main frame and can be adjusted so that the wing
stops in a level position when lowered.
IMPORTANT! - Operating with the wings misaligned with the
main frame can cause excess stress on the wing drive belts,
leading to accelerated wear.
24
Pro-Flex 120 Series Operator’s Manual
OPERATING THE MOWER
DAILY CHECK LIST
1) Always wear relatively tight and belted clothing to avoid
entanglement in moving parts. Wear sturdy, rough-soled work
shoes. Never operate tractor or implements in bare feet,
sandals or sneakers. Ensure other required PPE is in good
condition.
2) Ensure all safety shielding is properly installed and check that
all nuts and bolts are secure and pins are properly fastened.
3) Inspect all safety decals and ensure they are clean and in
legible condition.
4) Inspect wing and deck locks and ensure all pivot points and pull
mechanisms have free movement and are in good order.
5) Check condition of blades and security of attachment.
6) Ensure mower is properly connected to the tractor, adjusted
and in good operating condition.
7) Be sure wing release pull rope and hydraulic hoses are properly
secured and will not become entangled in PTO shaft.
8) Tall grass can hide obstacles. Carefully walk the entire area to
be mowed beforehand. Look for debris, rocks, tree limbs etc.
that will damage or be thrown by the mower blades. Identify
objects that cannot be removed. Set mower cutting height to
avoid contact.
9) Never permit any person other than the operator to ride or
board the tractor at any time.
10) Check that all lubrication points with grease fittings have been
lubricated as per schedule (Page 30).
11) Check the gearbox for possible oil leaks.
RAISING / LOWERING THE WINGS & DECKS
The mower wings and decks are raised into transport and service
position by hydraulic cylinders activated by the tractor remote
hydraulic circuit.
A valve is incorporated into the wing hydraulic system to prevent
unwanted movement of the wing cylinders during mowing. The valve
is de-activated at the same time as the wing locks by using the pull
rope.
To lower the wings from the transport position:
1. Ensure the deck transport locks are engaged (Page 19).
2. Pull the rope and hold in this position until the wings are fully
lowered.
3. Place the tractor hydraulic control in the lower position and
lower the wings. The deck cylinders will extend (lower) at the
same time.
4. With the wings are fully lowered, place the tractor hydraulic
control in the raise position to retract the deck cylinders fully.
5. Disengage the deck transport locks.
6. Lower decks to the ground.
25
Pro-Flex 120 Series Operator’s Manual
To raise the wings for transport:
1. Place the tractor hydraulic control in the raise position and
raise the mower decks.
2. Engage deck transport locks.
3. Pull the rope and hold in this position until the wings are fully
raised.
4. Release the rope to engage the wing locks for transport
(when fully raised).
Note that if the rope is released at any point while raising / lowering
the wings, the wings will stop in that position. To continue raising /
lowering, simply pull the rope and engage the tractor hydraulic
function.
ENGAGING THE MOWER
When engaging the mower, it is important to follow this procedure:
1) Lower the wings and decks into the working position. When
lowering decks on turf, travel forward slowly while lowering
wings in order to avoid scuffing the turf.
2) Ensure all deck cylinders are FULLY EXTENDED (pin mid-way
along slot). This allows for proper floatation of the decks during
mowing.
3) Ensure the wing lock lever is fully in the down position.
This will ensure the wings are locked down during mowing.
4) Raise decks into Pro-Lift-N-Turn Position (see Page 27).
5) Set the tractor engine speed at 1000 rpm maximum.
6) Ensure that everyone is clear of the mower.
7) Engage the tractor PTO lever.
8) Select the proper ground speed gear and slowly engage the
clutch.
9) Once the mower has come up to speed, slowly increase the
tractor throttle to desired rpm.
MOWING
The Pro-Flex 120 mower is a very versatile cutting machine that
allows the operator to maintain turf on undulating terrain in a
productive manner. Drive safely, cut safely. Be sure to idle the tractor
back before engaging the PTO, and shut the tractor off before leaving
the tractor.
NOTE:
26
Under normal cutting conditions, it may be desirable to
operate the tractor at less than 540 rpm PTO speed,
reducing fuel consumption and noise levels. Select a
suitable ground speed gear to maintain proper cut quality.
Pro-Flex 120 Series Operator’s Manual
Pro Lift-N-TurnTM SYSTEM
TM
Your Pro-Flex 120 is equipped with the Pro Lift-N-Turn system. This
feature allows the operator to temporarily lift all five cutting decks just
off the turf without shutting down the PTO. Utilizing the Pro Lift-NTM
Turn
system when mowing near cart paths or other roadways,
allows the operator to move from section to section without raising the
wings to the full transport position or disengaging the PTO. Pro LiftTM
N-Turn can also be used to start the mower in tall grass. Engaging
the blades with the decks raised will reduce start-up loading on the
mower drivetrain.
TM
The Pro Lift-N-Turn
system is activated automatically when the
wings are lowered and the pull rope released. The operator can
temporarily lift the mower decks during operation using the tractor
hydraulic valve until the deck cylinders are fully retracted. Once the
mower is again in position to mow, the operator can lower the decks
and continue mowing. It is possible to perform this without
disengaging the PTO.
The mower blades remain at cutting speed while using the Pro
TM
Lift-N-Turn system. Do not proceed into areas that may have
loose debris that may be thrown by the mower blades.
TM
NOTE: The Pro Lift-N-Turn system is designed to be engaged for
short durations only. If travelling over long distances with the decks in
the raised position, disengage PTO before proceeding.
MOWING WHILE REVERSING TRACTOR
The unique design of the hitch and deck mounting allows the mower
to operate equally well in the reverse direction. This is excellent for
cutting in confined areas and cleaning up leaves in the fall.
OPERATING ON HILLY TERRAIN
When operating on hilly terrain, proceed with caution and drive
carefully. If the tractor has four wheel drive, make sure it is engaged.
On two wheel drive tractors equipped with a differential lock, apply
while driving straight on the hills; disengage to allow for normal
turning.
Use care while turning on hillsides in wet conditions. The weight
of the mower behind the tractor may push the tractor
unexpectedly. Drive slowly around sand traps, river banks, etc.
27
Pro-Flex 120 Series Operator’s Manual
CLEARING BLOCKAGES
If a deck discharge chute becomes clogged during mowing:
1) Stop the tractor and set parking brake.
2) Reduce engine speed to idle.
3) Disengage the PTO, let the mower come to a complete stop
and stop the engine.
4) Ensuring that the tractor engine is turned off, approach blocked
discharge chute and clear debris as required.
NEVER attempt to clear blockages with tractor engine running!
Always ensure the engine is OFF and the tractor parking brake is
set before clearing blockages.
STOPPING THE MACHINE IN AN EMERGENCY
All function of the Pro-Flex 120 mower is controlled through the
tractor. In the event of an emergency, follow the measures specified
by tractor manufacturer as outlined in the tractor operator’s manual.
TRANSPORTING THE MOWER
The Pro-Flex 120 mower is NOT designed for use on public
roadways. Use an appropriate transportation method such as a
trailer or float to move mower from site to site if required.
When transporting the Pro-Flex 120 from site to site, ensure the wings
and decks are in the raised position and wing and deck safety locks
are engaged.
Use an appropriate sized vehicle to tow the Pro-Flex 120 mower.
Do not tow with vehicles that are less than 1035lb, vehicle
handling and braking characteristics will be diminished.

LUBRICATION
A properly maintained lubrication schedule will provide a smooth running machine for many
years. Some pivot locations have grease fittings. The following information shows and
describes where lubrication points are located and what types of lubricant are required.
GREASE SPECIFICATIONS
All greases are not compatible. Grease incompatibility will decrease the lubrication
ability of the grease, and can cause premature part failure.
Grease can have mineral or synthetic base oils and thickening agents such as lithium, calcium,
barium, sodium, or aluminum
What We Use:
- Progressive uses Shell Gadus S2 V220 2
- This grease has: - A mineral oil base
- A lithium-12 hydroxy thickener (“lithium” thickener)
- Extreme Pressure additives (EP)
- An NLGI Grade 2
Recommended Grease Properties
The grease you use for this machine must have these properties:
 NLGI grade 2
1
 Lithium thickener (NOT LITHIUM COMPLEX)
 Kinematic Viscosity at 40°C is no greater than 220 cSt
 Dropping Point Less than 400° F
 General Purpose Grease, Not Heavy Duty
2
 No MOLY (molybdenum disulphide) additives in the grease
3
 No synthetic grease
4
 No High Temperature Grease
Notes on grease compatibility:
1) If a thickener other than lithium is used (including lithium complex), the existing grease
will be contaminated and the lubrication properties may be lost leading to component
damage.
2) Molybdenum Disulfide (Moly) is an additive used in slow moving, extreme load
applications. The particles in the “Moly” will actually increase bearing wear in a high
speed mower application. Generally speaking Moly based greases will be grey in
colour.
3) If synthetic base oil is used rather than mineral base oil, the grease will be
contaminated; the lubrication properties may be lost leading to component damage.
4) We do not recommend the use of “High Temperature” greases, mower component
temperature should never reach temperatures above the level at which general
purpose greases can operate. “High Temperature” greases may contain thickeners
that are not compatible with Lithium-12 Hydroxy based thickeners.
Grease with these features is considered to be a “General Purpose Grease”. Use on all grease
point locations on your Progressive Mower. Check the properties of the grease you wish to use
with your supplier prior to use.

“V” BELT DRIVE
BELT TENSION - 100h / Monthly
Proper belt tension is a fundamental factor in successful V-belt
operation. Lack of tension will cause slippage, and too much tension
will cause excessive belt stretch as well as damage to the drive
components, such as bearings and shafts. To assess the condition of
the automatic tensioner, the following procedure is recommended.
At the mid-point of the span, apply a deflection force with a spring
scale in the direction perpendicular to the span until the belt is
deflected the 3/8”.
The recommended force to deflect the belt is a minimum of 5 lbs. to a
maximum of 7 lbs.
The first 24 to 48 hours of operation is the belt “run in” period. To
ensure satisfactory belt performance, belt tension should be checked
during this time period.
BELT ADJUSTMENT
All deck drive belts utilize an automatic rubber torsion tensioning
device. These tensioners are pre-set upon installation and require no
further adjustment or maintenance.
In normal service the tensioner arm angle (see detail at right) should
read between 30 degrees and 15 degrees.
A tool is provided to allow easy release of belt tension using a ½”
drive breaker bar or ratchet.

BLADE SERVICING
Always observe proper lock-out procedures when performing
any maintenance work including changing or servicing the
blades. Always remove and retain the ignition switch key, ensure
parking brake is engaged, and block and or support machine
using equipment designed for the task.
Be sure deck and wing safety locks are engaged when working
on decks in the raised position.
Use gloves when handling mower blades. Blades can be very
sharp.
Inspect blades before each use to determine that they are mounted
tightly and are in good condition. Replace any blade that is bent,
excessively nicked, worn or has any other damage. Small nicks can
be ground out when sharpening.
Use only original equipment blades when replacing worn out
mower blades. They are made of special steel alloys and
subjected to rigid heat-treat and inspection requirements.
Substitute blades may not meet these specifications and MAY
BE DANGEROUS.
BLADE REMOVAL AND INSTALLATION
Replace any blade that is bent, excessively nicked, worn or has any
other damage. Small nicks can be ground out when sharpening.
When replacing mower blades, be aware of blade rotation as blades
rotate in opposite directions. Ensure the cutting edge is facing in the
correct direction
The Pro-Flex 120 is equipped with 4 left hand (LH) rotation blades
and 1 right hand (RH) rotation blade*:
 4 LH ROTATION BLADES painted BLACK.
 1 RH ROTATION BLADES painted RED
*RH & LH rotation is determined by the top blade tip travel direction
when viewed from above. RH = Clock-wise, LH = Counter Clock-wise
See Page 7 for individual deck blade rotation direction.
A 1” diameter pilot centers the blade on the spindle with two 1/2”
grade 5 fasteners. When installing blades, be sure that the spindle
pilot is properly seated in the blade and the fasteners are in good
condition and properly tightened per the chart on at the beginning of
this section.
36
Pro-Flex 120 Series Operator’s Manual
BLADE SHARPENING
Use gloves when handling mower blades. Blades can be very
sharp.
IMPORTANT! When sharpening blades, be sure material removed is
equal on both sides of the blade. Unbalanced blades will cause
excessive vibration leading to cracks in machine components.

Clean all material from the blade prior to sharpening and
balancing.

Grind or file blades following original pattern as shown.
 Sharpen to a razor edge. Do not sharpen back side of blade.
Use the supplied cone balancer to verify blade balance. When
the blade is correctly balanced, the blade will remain horizontal.
SPINDLE SERVICE
Each spindle is supported by two ball bearings. No adjustment of
clearance is required. Running clearance is pre-set during assembly
by tightening the 1” NF left hand nut on top of the pulley.
Periodically inspect blade spindles by grasping pulley, and moving
from side to side. If any free play is noted, replace or repair.
SPINDLE ASSEMBLY REMOVAL
1) Relieve tension from belt, and remove belt from the spindle
pulley.
2) Raise the mower decks into the service position and ensure the
deck safety locks are secure
3) Remove blade from spindle.
4) From under the deck, loosen the four nuts that hold the spindle
assembly to the deck.
5) Remove the complete spindle assembly and pulley out through
the hole in the deck.
SPINDLE ASSEMBLY INSTALLATION
Reverse above procedure. Be sure spindle mounting area of deck is
clean of any foreign material before attaching spindle assembly.

Pro-Flex 120 Series Operator’s Manual
SPINDLE ASSEMBLY REPAIR
Note: A video showing this rebuild procedure is available on our
website: http://www.progressiveturfequip.com/service
Spindle repair requires special skills and tools, a shop press is
required.
If your shop is not properly equipped or your
mechanics are not properly trained in this type of repair,
complete spindle assemblies are available as service parts.
1) Remove LH Nut (3), lock washer (2), pulley (1), spacer (12),
washer (8) & shim (4) from spindle assembly. The spindle nut
is left-hand thread.
Make sure that the press ram and bed 100% square to each
other. If bearings are not square in housing, bearings will wear
out prematurely.
2)
Place assembly in shop press with support under spindle
housing flange and press spindle down through housing.
3) Remove bottom bearing from spindle and top bearing from
housing
IMPORTANT! Removing bearings from spindle / housing
causes permanent damage to the bearings. New bearing
must be used in re-assembling the spindle.
4) Inspect bearing spacer faces for wear. If any wear is present,
replace spacer with new.
IMPORTANT! Failure to replace a worn or damaged spacer
will lead to premature top bearing wear.
5) Place housing in press (upside down). Pressing on outer
race; install bottom bearing (11) into housing.
6) Place spindle in press. Place dirt shield (8) and shim (7) on
spindle.
7) Pressing on inner race of bottom bearing, press housing /
bearing on to spindle. A steel tube will be required to slide over
the spindle and press on inner race.
8) Install bearing spacer (6) with hole end up.
9) Set top bearing on to spindle. Pressing on inner race, press
top bearing on to spindle.
IMPORTANT! Due to design tolerances, the top bearing
may appear to be loose in the housing. This is normal and
is not detrimental to the operation of the spindle.
10) Install shim washer (4), dirt shield (8), pulley spacer (12), key
(15), pulley (1) and set screw (14) on to spindle.
11) Install LH lock washer (2) and LH nut (3) and torque to 60 ft-lb.
Rotate the housing six revolutions by hand and check for smooth, free
movement.
The assembly is now ready for installation into the mower deck.

HYDRAULICS
Hydraulic Oil – Conventional Anti-Wear Tractor-Hydraulic Fluid
Biodegradable Oils – Consult Factory for compatibility analysis.
Hydraulic fluid escaping under pressure can penetrate the skin.
Seek medical attention at once if injured by escaping fluid.
During your daily inspection repair all leaks before they create a major
problem. Do not use your hand to check for hydraulic oil leaks. Use a
piece of cardboard instead. Hydraulic fluid escaping under pressure
can penetrate the skin causing serious injury. If skin penetration
occurs, seek medical attention immediately. Relieve all pressure
before disconnecting hoses.
When servicing any hydraulic component of the mower ensure that all
decks and wings are in their lowered position and all hydraulic
pressure is relieved. Pressure can be maintained in the hydraulic
circuits long after the power source and pump have been shut down.
Relieve all pressure before disconnecting hoses or tubes.
Tighten all connections before applying pressure.
When connecting the hydraulic couplers to the tractor, be sure that
both coupler ends are clean. Dirt in the hydraulic system can block
the orifice in the cylinder ports or cause premature wear & failure of
hydraulic components on the mower or tractor.
The hydraulic system on the Pro-Flex 120 mower is divided into 2
simple systems; one to operate the deck lift cylinders, the other to
operate the wing lift cylinders.
NOTE- A quarter-turn ball valve is located in the wing cylinder circuit
(at the wing lock release arm). This valve is used to shut off the
hydraulic system to the wing lift cylinders while mowing to avoid
unwanted wing movement during mowing. The valve is automatically
closed when the wing lock pull rope is released. If the lock release
arm fails to return to a horizontal position, the valve may stay open
leading to uneven cutting & reduced belt life.
VALVE CLOSED
VALVE OPEN
BALL VALVE
All hydraulic cylinders are equipped with a .040” diameter orifice in
one of the elbow connectors. This orifice is present to throttle the
cylinder speed to an acceptable level. When repairing the hydraulic
system ensure that this orifice elbow is present and free of debris that
could block the orifice.

Pro-Flex 120 Series Operator’s Manual
SUPPORTING MACHINE FOR SERVICE
(2) Points are available to lift the mower off of the ground for servicing
the transport tires / wheels / bearings at the base of the axle as shown
in the accompanying illustration. Use a bottle or service jack to raise
the wheel from the ground and place a wooden block or other suitable
support under the rectangular tube.
Do not support the machine on cinder blocks, hollow tiles or
other members that may fail under continuous load.
Never perform service on a machine that is supported solely by a
jack. Always ensure proper blocking is placed to support load
during service.
Transport tires must be changed with the wings in the raised
position. Ensure the machine is on a flat, level surface and the
wing locks are fully engaged before attempting to lift the
machine.
TRANSPORT TIRES
Inspect tires daily for wear or damage. Check tire pressures weekly
with an accurate pressure gauge. Do not inflate tires beyond 35 psi.
Mounting and dismounting tires from rims can be dangerous and
should be performed by trained personnel using correct tools,
equipment and procedures.
LONG-TERM STORAGE
If the mower is not to be used for an extended period of time (4
months or longer) it is recommended that the following maintenance
steps are followed:
1) Thoroughly wash mower, removing all grass clipping residue
from deck undersides & mower framework.
2) Add grease to all grease points.
3) Check gearbox oil for proper level.
4) Relieve tension on all V-belts by removing belt from tensioner
pulley.
5) Inspect all drive belts & pulleys.
6) Inspect all blade spindle bearings for excessive play.
7) Inspect all blades for serviceable condition.
When returning the mower to service after long-term storage:
1) Check tightness of all blade fasteners.
2) Add grease to all grease points.
3) Re-install all V-belts on tensioner pulleys.
4) Ensure all pivot points move freely.
5) Change gearbox oil.
