instructions to operate the machine. Know controls
and how to stop the machine quickly.
• Watch for traffic when operating near or crossing
roadways.
• Do not put hands or feet under mower deck or near
rotating parts.
• Use extra care when loading or unloading the
machine into a trailer or truck. This unit should not
be driven up or down a ramp onto a trailer or truck
under power, because the unit could tip over,
causing serious personal injury. The unit must be
pushed manually on a ramp to load or unload
properly.
• Clear the area of objects such as rocks, toys, wire,
etc., which could be picked up and thrown by the
blade. A small object may have been overlooked
and could be accidentally thrown by the mower in
any direction and cause injury to you or a
bystander. To help avoid a thrown objects injury,
keep children, bystanders and helpers at least 75
feet from the mower while it is in operation. Always
wear safety glasses or safety goggles during
operation or while performing an adjustment or
repair, to protect eyes from foreign objects. Stop
the blade(s) when crossing gravel drives, walks or
roads.
• Never make a cutting height adjustment while
engine is running if operator must dismount to do
so.
• Wear sturdy, rough-soled work shoes and close-
fitting slacks and shirts. Do not wear loose fitting
clothes or jewelry. They can be caught in moving
parts. Never operate a unit in bare feet, sandals, or
sneakers.
• Be sure the area is clear of other people before
mowing. Stop machine if anyone enters the area.
• Check overhead clearance carefully before driving
under power lines, wires, bridges or low hanging
tree branches, before entering or leaving buildings,
or in any other situation where the operator may be
struck or pulled from the unit, which could result in
serious injury.
• Never carry passengers.
• Disengage blade(s) before shifting into reverse and
backing up. Always look down and behind before
and while backing.
• Be aware of the mower and attachment discharge
direction and do not point it at anyone. Do not
operate the mower without either the entire grass
catcher or the chute guard in place.
• Disengage all attachment clutches, thoroughly
depress the brake pedal, and shift into neutral
before attempting to start engine.
• Your mower is designed to cut normal residential
grass of a height no more than 10". Do not attempt
to mow through unusually tall, dry grass (e.g.,
pasture) or piles of dry leaves. Debris may build up
on the mower deck or contact the engine exhaust
presenting a potential fire hazard.
• Slow down before turning. Operate the machine
smoothly. Avoid erratic operation and excessive
speed.
• Never leave a running machine unattended. Always
turn off blade(s), place transmission in neutral, set
park brake, stop engine and remove key before
dismounting.
• Turn off blade(s) when not mowing.

• Keep children out of the mowing area and in
watchful care of an adult other than the operator.
2. SLOPE OPERATION
• Slopes are a major factor related to loss of control
and tip-over accidents which can result in severe
injury or death. All slopes require extra caution. If
you cannot back up the slope or if you feel uneasy
on it, do not mow it.
• Be alert and turn machine off if children enter the
area.
• Before and when backing, look behind and down
for small children.
• For your safety, use the slope gauge included as
part of this manual to measure slopes before
operating this unit on a sloped or hilly area. If the
slope is greater than 15° as shown on the slope
gauge, do not operate this unit on that area or
serious injury could result.
• Never carry children. They may fall off and be
seriously injured or interfere with the safe machine
operation.
• Never allow children under 14 years old to operate
the machine. Children 14 years and over should
only operate machine under close parental
supervision and proper instruction.
DO:
• Use extra care when approaching blind corners,
shrubs, trees or other objects that may obscure
your vision of a child or other hazard.
• Mow up and down slopes, not across.
• Remove obstacles such as rocks, limbs, etc.
• Remove key when machine is unattended to
prevent unauthorized operation.
• Watch for holes, ruts or bumps. Uneven terrain
could overturn the machine. Tall grass can hide
obstacles.
4. SERVICE
• Use slow speed. Choose a low enough gear so that
you will not have to stop or shift while on the slope.
Always keep machine in gear when going down
slopes to take advantage of engine braking action.
• Use extreme care in handling gasoline and other
fuels. They are extremely flammable and the
vapors are explosive.
• Use only an approved container.
• Follow the manufacturer’s recommendations for
wheel weights or counterweights to improve
stability.
• Never remove fuel cap or add fuel with the engine
running. Allow engine to cool at least two minutes
before refueling.
• Use extra care with grass catchers or other
attachments. These can change the stability of the
machine.
• Replace fuel cap securely and wipe off any spilled
fuel before starting the engine as it may cause a
fire or explosion.
• Keep all movement on the slopes slow and
gradual. Do not make sudden changes in speed or
direction. Rapid engagement or braking could
cause the front of the machine to lift and rapidly flip
over backwards which could cause serious injury.
• Extinguish all cigarettes, cigars, pipes and other
sources of ignition.
• Never refuel the machine indoors because fuel
vapors will accumulate in the area.
• Avoid starting or stopping on a slope. If tires lose
traction, disengage the blade(s) and proceed slowly
straight down the slope.
• Never store the fuel container or machine inside
where there is an open flame or spark, such as a
gas hot water heater, space heater or furnace.
• Never run a machine inside a closed area.
DO NOT:
• To reduce fire hazard, keep the machine free of
grass, leaves or other debris build-up. Clean up oil
or fuel spillage. Allow machine to cool at least 5
minutes before storing.
• Do not turn on slopes unless necessary; then, turn
slowly and gradually downhill, if possible.
• Do not mow near drop-offs, ditches or
embankments.The mower could suddenly turn over
if a wheel is over the edge of a cliff or ditch, or if an
edge caves in.
• Before cleaning, repairing or inspecting, make
certain the blade and all moving parts have
stopped. Disconnect the spark plug wire, and keep
the wire away from the spark plug to prevent
accidental starting.
• Do not mow on wet grass. Reduced traction could
cause sliding.
• Check the blade and engine mounting bolts at
frequent intervals for proper tightness. Also,
visually inspect blade for damage (e.g., excessive
wear, bent, cracked). Replace with blade which
meets original equipment specifications.
• Do not try to stabilize the machine by putting your
foot on the ground.
• Do not use grass catcher on steep slopes.
3. CHILDREN
• Keep all nuts, bolts and screws tight to be sure the
equipment is in safe working condition.
Tragic accidents can occur if the operator is not alert to the
presence of children. Children are often attracted to the
machine and the mowing activity. Never assume that chil-
dren will remain where you last saw them.

• Never tamper with safety devices. Check their proper
operation regularly. Use all guards as instructed in
this manual.
• Do not change the engine governor settings or
overspeed the engine. Excessive engine speeds are
dangerous.
• After striking a foreign object, stop the engine,
remove the wire from the spark plug and thoroughly
inspect the mower for any damage. Repair the
damage before restarting and operating the mower.
• Observe proper disposal laws and regulations.
Improper disposal of fluids and materials can harm
the environment and the ecology.
• Prior to disposal, determine the proper method to
dispose of waste from your local Environmental
Protection Agency. Recycling centers are established
to properly dispose of materials in an environmentally
safe fashion.
• Grass catcher components are subject to wear,
damage and deterioration, which could expose
moving parts or allow objects to be thrown. For your
safety protection, frequently check components and
replace with manufacturer’s recommended parts
when necessary.
• Use proper containers when draining fluids. Do not
use food or beverage containers that may mislead
someone into drinking from them. Properly dispose of
the containers immediately following the draining of
fluids.
• Mower blades are sharp and can cut. Wrap the
blade(s) or wear gloves and use extra caution when
servicing blade(s).
• Check brake operation frequently. Adjust and service
as required.
• DO NOT pour oil or other fluids into the ground, down
a drain or into a stream, pond, lake or other body of
water. Observe Environmental Protection Agency
regulations when disposing of oil, fuel, coolant, brake
fluid, filters, batteries, tires and other harmful waste.
• Muffler, engine and belt guards become hot during
operation and can cause a burn. Allow to cool down
before touching.
WARNING - YOUR RESPONSIBILITY: Restrict the use of this power machine to persons who
read, understand and follow the warnings and instructions in this manual and on the machine.

DRIVE HANDLES
The Drive Handles (Left and Right) are located at the top of the Control Tower. (See Figure 8) The drive handles
are used to move, (propel) steer and stop the Z-series. The drive handles will return toward the neutral position
without driver input. However, the driver should place the Drive Handles in the neutral position. Unless the Drive
Handles are placed in the neutral position the Z-Series may creep. When the Drive Handles are in the neutral
position the unit does not move.

Download from Www.Somanuals.com. All Manuals Search And Download.
When the engine is running, the throttle is set and the Drive Handles are moved from the neutral position, the unit
moves in accordance with the driver’s input (push, pull or both). When the driver releases the handles they
immediately return towards the neutral position and the unit will slow and stop moving (while the engine continues
to run).
The rear wheels propel and steer the unit. The Left Drive Handle controls the Left rear wheel and the Right Drive
handle controls the Right rear wheel. Push a handle forward and the respective wheel turns forward. Pull a handle
back and the respective wheel turns in reverse.
Each Drive handle has a range in the forward position (push) and the reverse position (pull). If a Drive Handle is
moved to the full position (until it stops) the rear wheel turns as fast as the throttle is set. Positions between
neutral and full are proportional across the range based on the throttle setting. The Drive Handles can be moved
together in the same direction or independent of each other in any combination (i.e. Left push, Right pull).
NOTE: The Drive Handles will return toward neutral when released, but they should be placed in neutral by the
driver. If the Drive Handles are not placed in neutral, the tractor may creep.
Speed Control

Wing Nut
Figure 9
SPEED CONTROL BAR
The Speed Control Bar is connected to the console with two wing nuts. (See Figure 9). It is used as a grab bar for
entry or exit from the tractor and allows for pre-set maximum travel speed.
• Loosen the two wing nuts located on either side of the plastic console.
• Rotate speed control bar to desire location.
• Tighten wing nut to secure speed control bar.
NOTE: Limit loosening the wing nuts to 1 1/2 turns. This will insure proper assembly of the screw not visible on
the other side of the plastic console. Refer to parts book if screw fell and wing nuts are no longer tightening.
The Speed Control Bar also aids the drive handles in making “perfect U-turns”. Grasping both Drive Handles and
the Speed Control Bar at the same time to move forward, release the Left Drive Handle to turn left and then re-
grasp to continue straight ahead or release the Right Drive Handle to turn right. Refer also to the Quick

QUICK REFERENCE CHART
The Z-series can turn with a zero radius. The Z-series uses the rear tires to turn. When turning with a zero radius,
the rear tires are used as the pivot point. A conventional tractor can make a circle but it needs a turning radius,
usually based on the distance between the front and rear wheels. With a shorter overall length and a zero turn
radius, the Z-series has excellent maneuverability.
The Z-series does not have a steering wheel, instead drive handles are used to steer and to propel the unit. When
the Drive Handles are in the full positions (pull or push) the wheels turn at full speed based on the throttle setting.
Positions between neutral and full are proportional across the range based on the throttle setting. This is a
departure from what most of us are accustomed. Please take a few minutes to study the diagrams that follows.

DRIVING THE Z-SERIES
1. Start the engine and allow it to idle for a moment.
2. Set the throttle to the fastest position (full open).
3. Release the Parking Brake by depressing the Parking Brake Pedal.
4. Gradually provide input by moving the Drive Handles in the desired direction.
Note: The Z-series speed, while driving, is based on the position of the Drive Handles. Push or pull the handles
to full for maximum speed and positions in between neutral and full for slower speeds.
DRIVING ON SLOPES
Before operating the Z-series on any slope:
1. Use the Slope Gauge to determine if the slope is safe for operation.
2. If safe for operation, walk the slope and look for hazards such as rocks, mounds, ruts, stumps or other
irregularities.
3. After removing debris and identifying irregularities of the slope, back the Z-series up the steepest slope you
intend to work. If it cannot negotiate the slope in reverse, the slope is too steep.
Use the following guidelines when operating on a slope:
WARNING: Do not mow on inclines with a slope greater than 15 degrees (a rise of approximately
2-1/2 feet every 10 feet). Slopes greater can cause the Z-series to overturn and cause serious injury.
• Drive UP and DOWN slopes. Never drive across slopes.
• Avoid turns. If you must turn, turn down the slope. Turning up a slope greatly increases the chance of roll
over.
• Avoid stopping when driving on a slope. If you must stop, start slowly and smoothly to reduce the chance of
flipping the Z-series over backwards.
STOPPING THE Z-SERIES
1. Release pressure on the Drive Handles (guiding them to neutral).
2. Disengage the PTO (down).
3. Depress the parking brake and hold.
4. Push the parking brake handle down. (See Figure 8)
5. Move the throttle lever to the slowest position (toward turtle).
6. Turn the Ignition to the OFF position.
7. Remove the key.
OPERATING THE PTO (POWER TAKE OFF) CLUTCH
Note: The operator must remain seated at all times. If the operator leaves the seat without turning off the PTO,
the engine will automatically shut off.
NOTE: Be sure lift lever is not in the L position when the PTO is engaged.
Note: When the Z-series drives in reverse with the PTO engaged (Up), the PTO is automatically disengaged
(Down).
1. Sit in the seat and start the engine.
2. Move the throttle lever to the FAST position (rabbit).
3. Pull up on the PTO to put it in the RUN position. See Figure 4.

CLEAN THE BATTERY
Clean the battery by removing it from the unit and washing with a baking soda and water solution. If necessary,
scrape the battery terminals with a wire brush to remove deposits. Coat terminals and exposed wiring with grease
or petroleum jelly to prevent corrosion.
BATTERY STORAGE
The battery loses some of its charge each day when the unit is not used. Never store battery without a full
charge. Recharge battery before returning to service or every two months, whichever occurs first. When storing
unit for extended periods, disconnect battery cables. Removing battery from unit is recommended.
TIRES
The two front wheels are caster wheels that are free to swivel to accommodate the direction of the Z-series. The
tires on the caster wheels are made of solid polyurethane that do not require air.
The two rear wheels are used to propel the Z-series in the direction of input from the drive handles. Inflation
pressure of the rear tires is important for stability while the Z-series is in operation. If the tire diameter is not equal
between the two tires, the Z-series will pull to one side.
Use the following guidelines for maintaining the tires:
• Balance inflation pressure between the rear tires to help maintain straight travel (see tire side wall for
proper inflation pressure).
• Keep the valve caps in place and tightened to prevent air pressure loss.

SECTION 10: STORAGE
When storing the Z-series for longer than 30 days, use the following steps:
WARNING: Never store the engine with fuel in the tank if it is stored where fuel fumes can reach an
open flame, spark or pilot light (e.g., furnace, water heater, or clothes dryer).
1. Remove all gasoline from the fuel tank. Gum deposits can form on engine parts causing the engine to
malfunction.
2. Run the engine until it begins to falter.
3. Use the choke to continue operation until all fuel is gone from the carburetor and fuel tank.
4. Drain any remaining fuel from the fuel line at the carburetor or gas tank.
WARNING: Drain fuel into an approved container, in open air, and away from open flames.
Note: Fuel quality deteriorates when fuel is left in engine during warm weather. Poor fuel quality can cause
engine starting difficulties.
5. Crank the engine several times to distribute the oil.
6. Clean the engine and the entire Z-series thoroughly.
7. Lubricate all lubrication points.
8. Follow the battery storage guidelines (refer to BATTERY STORAGE for details).
9. Inflate tires at regular intervals.

SECTION 11: MOWING
For best results, consider the following recommendations:
• Mow the first two laps with the discharge pointing toward the center.
• Mow the next two laps with the discharge pointing outside (away from center) for a balanced cut and
improved appearance.
• Do not cut grass too short. The mower tends to "scalp" the grass. Shorter grass invites weeds and will
yellow quickly in dry conditions.
During some conditions, the mower may leave streaks of uncut material. Streaking can happen when cutting
heavy weeds and tall grass. In these conditions it may be necessary to cut the area a second time for a clean cut.
AVOIDING STREAKING
1. Mow the area often; cutting grass of shorter lengths helps to avoid streaks.
2. Operate the Z-series at full throttle and at a slower forward speed.
3. Maintain sharp blades and replace when worn.
4. Follow the mowing path shown below. (See Figure 29)
