The Pro-Flex series mowers are contour turf grass finishing mowers with a 10 foot cutting width, and
are designed to be pulled by a 30- 40 PTO horsepower utility tractor. These versatile mowers have the
ability to mow both contoured and flat terrain that requires a high quality finished after cut appearance.
They 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 control deck bounce as the Pro-Flex follows changing ground
contours.

Five independent floating decks
Cut height can be set on each deck between 3/4 inch and 3 inches
10’ foot cutting width with all decks down or 6 foot cutting width with the outer decks raised
Automatic rubber damped belt tensioners for consistent tension and long belt life
The Pro-Flex 120 features a combination of swivelling and rigid caster wheels ensures true
straight line tracking and easy turning without scuffing
The Pro-Flex Roller 120 features urethane rollers front and rear of each deck to better
follow contours and leave a pleasant striped finish on the turf.
Automatic mechanical deck locks for transport

GENERAL SAFETY PRECAUTIONS
The operator of this machine must have sufficient knowledge
and instructions in the care and operation of this mower and the
power unit being used before he / she uses the machine. Do
not allow unauthorized persons or children to operate the
machine. Do not allow riders on the machine.
It is the obligation of the operator to make sure that all guards
and shields are in place on the machine. Safety decals must be
in place and be readable –accidents may otherwise occur.
Contact your dealer or the manufacturer for replacement
manuals or decals.
Never use a machine that does not have an operator’s manual
available. Learn and understand the safety signs and symbols
on the machine and the operator instructions before you begin
to use the machine.
Wear personal protective equipment. Know and use the
protective equipment that is to be worn when operating or
servicing the machine. Hard hats, protective glasses and face
shields, protective shoes, gloves, reflector type vests, and ear
protection are types of equipment that may be required.
Prolonged exposure to loud noise can cause hearing damage.
Never operate a mower while under the influence of drugs or
alcohol. These make reflexes slow and put you and others in
grave danger. Always make sure you have full concentration
while mowing.
Adhere strictly to all regulations at the worksite pertaining to the
operation of this equipment.
Always disengage power takeoff (PTO) when transporting or
traveling between work sites.
Be prepared for emergencies. Have a first aid kit, fire
extinguisher and emergency contact information available at the
work site.
POWER UNIT SAFETY
The operator must have sufficient knowledge in the care and
operation of the power unit (tractor) before connecting power
unit to mower. Read and understand power unit operator’s
manual before connecting mower.
Power unit must be equipped with ROPS and seat belt.
Foldable ROPS must be secured in the upright position. Follow
recommendations of power unit manufacturer. Seat belt must
be worn at all times.
Power unit must be equipped with a 1-3/8” 6 spline 540 RPM
PTO connection. Never use PTO adapters to connect
implements. Never connect mower driveline to 1000 RPM
PTO.

Pro-Flex 120 Series Operator’s Manual
12
Hydraulic circuits to control mower functions must be set to
2000psi maximum working pressure.
OPERATING EQUIPMENT SAFELY
Never allow persons to stand between power unit and mower
while backing power unit up to hitch the mower.
Before hitching mower to power unit, place transmission in
neutral, set park brake, and turn engine off. Remove the
ignition key.
Make sure locking collar on PTO shaft is properly locked. If the
PTO shaft comes off during operation, personal injury or
equipment damage could result.
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.
Ensure that no bystanders are within 10 ft of mower when wing
transport locks 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.

Pro-Flex 120 Series Operator’s Manual
13
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.
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.

Pro-Flex 120 Series Operator’s Manual
14
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 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.

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.
