INTRODUCTION
Thank you for purchasing a Pro-Flex 120 mower. This product is designed and
manufactured to allow safe and productive mowing of contoured areas. A well-
maintained machine will provide years of reliable service.
FOREWORD
This is the Operator’s Manual for the Pro-Flex 120 mower. Keep it with the
mower at all times. This manual is intended as a guide to the safe use and
maintenance of the machine, so before you operate this machine, study this
manual carefully.
Replace this manual immediately if it becomes lost.
This manual is not considered all-inclusive, so for further information on specific
components, e.g. PTO shafts etc., refer to the respective documents included with
the manual set for this machine.
The Pro-Flex 120 is a contour turf grass finishing mower with a 10 foot cutting
width, and is designed to be pulled by a 30- 40 PTO horsepower utility
tractor. This versatile mower has the ability to mow both contoured and flat
terrain that requires a high quality finished after cut appearance. It can also blow
leaves while backing up or be equipped with optional mulching blades and baffles
to help return nutrients to the turf. High blade tip speed leaves a second-to-none
after cut appearance. Shock absorbers on each mowing deck eliminate deck
bounce as the Pro-Flex 120 follows changing ground contours.
Features:
Five independent floating decks
Cut height can be set on each deck between 3/4 inch and 3 inches
10’ foot cutting swath with all decks down or 6 foot cutting swath with the
outer decks raised
Automatic rubber damped belt tensioners for consistent tension and long life
Combination of swivelling and rigid caster wheels ensures true straight line
tracking and easy turning without scuffing
Automatic mechanical deck locks for transport
Applications:
Golf course roughs
Golf course fairways and bunkers
Corporate and industrial campuses
Park lands and recreational areas
Sports venues
Landscaped venues

are released.
Keep all bystanders well away from the machine when it is operating. Always
maintain a safe operating distance from personnel, other equipment, or vehicles.
Never operate the mower with deflectors or guards removed.
Mower blades can cause small objects and debris to be
thrown 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.
Mower is not intended for transport on public roadways.

11
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 torqued, 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.

12
WELDING AND 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.
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.
Relieve all pressure before disconnecting hoses or tubes.
Tighten all connections before applying pressure.

13
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
REAR MOWER DECK
The center rear mower deck, lift arm and drive belt are placed on a temporary
rack for transportation to the dealer. 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. The hydraulic hose ends should now be attached to a hydraulic source. Stroke the
center cylinder out completely. Remove the cylinder pin by loosening the 3/8”
bolt that holds it in place. 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. This will lock the pin in place.
8. 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.
9. Re-install the shields on the main drive train and the center deck.
10. 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.

MOWER SETUP FOR OPERATION
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 following decal is mounted to the
machine and shows 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.
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.
