WARNING
FAILURE TO FOLLOW SAFE OPERATING PRACTICES MAY RESULT
IN SERIOUS INJURY OR DEATH.
Read this manual completely as well as other manuals that came with your mower.•
DO NOT operate on steep slopes. To check a slope, attempt to back up it (with the•
cutter deck down). If the machine can back up the slope without the wheels slipping,
reduce speed and use extreme caution.
Under no circumstances should the machine be operated on slopes greater than 15•
degrees. ALWAYS FOLLOW OSHA APPROVED OPERATION.
Stay two cut widths away from slopes, drop offs, ditches and retaining walls.•
DO NOT mow on wet grass. Wet grass reduces traction and steering control.•
Keep all shields in place, especially the grass discharge chute.•
Before performing any maintenance or service, stop the machine and remove the•
spark plug wire and ignition key.
If a mechanism becomes clogged, stop the engine before cleaning.•
Keep hands, feet and clothing away from power-driven parts.•
Keep others off the mow• er (only one person at a time).
REMEMBER - YOUR MOWER IS ONLY AS SAFE AS THE OPERATOR!
HAZARD CONTROL AND ACCIDENT PREVENTION ARE DEPENDENT UPON THE AWARENESS,
CONCERN, PRUDENCE, AND PROPER TRAINING OF THE PERSONNEL INVOLVED IN THE
OPERATION, TRANSPORT, MAINTENANCE, AND STORAGE OF THE EQUIPMENT.
This manual covers the operating instructions and illustrated parts list for:
SFZ61-30BS with a serial number of G6800001 to G6899999

OPERATION CONSIDERATIONS2.4
Know the function of all controls and how to stop1.
quickly.
WARNING
DO NOT operate on steep slopes.To check a slope,
attempt to back up it (with the cutter deck down).
If the machine can back up the slope without the
wheels slipping, reduce speed and use extreme
caution. Under no circumstances should the
machine be operated on slopes greater than 15
degrees. See Figure 2-2, Page 7 to determine
approximate slope of area to be mowed. ALWAYS
FOLLOW OSHA APPROVED OPERATION.
Reduce speed and exercise extreme caution on2.
slopes and sharp turns to prevent tipping or loss
of control. Be especially cautious when changing
directions on slopes.
Stay two cut widths away from slopes, drop offs,3.
ditches and retaining walls.
To prevent tipping or loss of control, start and stop4.
smoothly, avoid unnecessary turns and travel at
reduced speed. Use caution when operating the
mower on an incline with the optional grass catcher
installed.
Immediately apply the parking brake if you lose5.
steering control while operating. Inspect the machine
and correct the problem before continuing to operate.
When using any attachment, never direct the6.
discharge of material toward bystanders or allow
anyone near the machine while in operation.
Before attempting to start the engine, with the7.
operator in the seat, disengage power to the cutter
deck, place the steering control levers in the neutral
position and engage the parking brake.
If the mower discharge ever plugs, shut off the8.
engine, remove the ignition key, and wait for all
movement to stop before removing the obstruction.
WARNING
DO NOT use your hand to dislodge the clogged
discharge chute. Use a stick or other device to
remove clogged material after the engine has
stopped running and the blades have stopped
turning.
Be alert for holes, rocks, roots and other hidden9.
hazards in the terrain. Keep away from any drop-offs.
Beware of overhead obstructions (low limbs, etc.)
and underground obstacles (sprinklers, pipes, tree
roots, etc.). Cautiously enter a new area. Be alert for
hidden hazards.
Disengage power to cutter deck before backing up.10.
Do not mow in reverse unless absolutely necessary
and then only after observation of the entire area
behind the mower. If you must mow in reverse,
maintain a constant lookout to the rear of the
machine and mow slowly.
DO NOT turn sharply. Use care when backing up.11.
Disengage power to cutter deck before crossing12.
roads, walks or gravel drives.
Mow only in daylight or good artificial light.13.
NEVER raise the deck with the blades engaged.14.
Take all possible precautions when leaving the15.
machine unattended, such as disengaging the
mower, lowering the attachments, setting the parking
brake, stopping the engine, and removing the key.
Disengage power to the attachments when16.
transporting or when not in use.
The machine and attachments should be stopped17.
and inspected for damage after striking a foreign
object, and damage should be repaired before
restarting and operating the machine.

engine is running or immediately after stopping.
These areas may be hot enough to cause a
burn.

Section 2
Any or all parts of the Roll-Over Protection System MUST
NOT be removed. Failure to adhere to this guideline could
result in injury or death.
The potential exposure of the seat belt to severe
environmental conditions make it crucial to inspect the seat
belt system regularly.
It is recommended that the seat belt be inspected on a
daily basis for signs of damage. Any seat belt system that
shows cuts, fraying, extreme or unusual wear, significant
discoloration due to UV exposure, dirt or stiffness, abrasion
to the seat belt webbing, or damage to the buckle, latch
plate, hardware or any other obvious problem should be
replaced immediately.
WARNING
Failure to properly inspect and maintain the seat
belt can cause serious injury or loss of life.
Check the full length of the seat belt webbing for1.
cuts, wear, fraying, dirt and stiffness. See Figure 2-1.
Check the seat belt webbing in areas exposed to2.
ultra violet rays from the sun or extreme dust or
dirt. If the original color of the webbing in these
areas is extremely faded and/or is packed with dirt,
the physical strength of this webbing may have
deteriorated. If this condition exists, replace the seat
belt system.
Check the buckle and latch for proper operation3.
and determine if the latch plate is excessively worn,
deformed, or if the buckle is damaged or cracked.
See Figure 2-1.

DANGER
DO NOT run the engine inside a building or
a confined area without proper ventilation.
Exhaust fumes are hazardous and contain
carbon monoxide which can cause brain injury
and death.
Keep hands and feet away from cutter blades and18.
moving parts. Contact can injure.
Transport the mower using a heavy duty trailer19.
or truck. Ensure the trailer or truck has all of the
necessary lighting and markings as required by
laws, codes, and ordinances. Secure a trailer with a
safety chain.
Be cautious when loading and unloading onto20.
trailers or trucks. Use only a full width ramp. Ramp
angle should be no more than 15 degrees. Back up
the ramp and drive down forward.
When transporting the mower, make sure the park21.
brake is engaged, the steering control levers are in
the neutral position, the engine is off with the key
removed, and the wheels have been blocked.
Tie the mower down securely using straps, chains,22.
cable, or ropes. Both front and rear straps must be
directed down and outward from machine.
Use care when approaching blind corners, shrubs,23.
trees, or other objects that may obscure vision.
NEVER leave the machine running unattended.24.
ROLL-OVER PROTECTION SYSTEM2.5
WARNING
The seat belt must be securely fastened during
operation. Failure to do so could cause serious
injury or loss of life.
This mower has been designed for good traction and
stability under normal mowing conditions. However, caution
must be used when traveling on slopes, especially when the
grass is wet. Do not mow on wet grass.Wet grass reduces
traction and steering control.
