Operator Safety
Slope Operation
Safety
Operation on slopes can be dangerous. Using the unit on a slope
that is too steep where you do not have adequate wheel traction
(and control) can cause sliding, loss of steering, control, and
possible rollover. You should not operate on a slope greater than a
5.4 foot rise over a 20 foot length (15 degrees).
Controls
Always mow across slopes, not up and down (to maintain traction
on the wheels) and avoid sudden turns or rapid speed changes.
Reduce speed and use extreme caution on ALL slopes.
Also, note that the surface condition you are on can greatly impact
your ability to safely operate this machine. Operating on wet or
slippery slopes can cause sliding and loss of steering and control.
Do not operate on slopes that are slippery, wet, or have soft soil
conditions.
If you feel unsure about operating the unit on a slope, don’t do it.
It’s not worth the risk.
Operation
Thrown Objects
This unit has spinning mower blades. These blades can pick up and
throw debris that could seriously injure a bystander. Be sure to clean up
the area to be mowed and remove objects that could be thrown by the
blade BEFORE you start mowing.
Maintenance
Do not operate this unit without the entire grass catcher or discharge
guard (deflector) in place.
Also, do not allow anyone in the area while the unit is running! If
someone does enter the area, shut the unit off immediately until they
leave
Moving Parts
Troubleshooting
This equipment has many moving parts that can injure you
or someone else. However, if you stay in the operator zone
(stay seated in the seat), and follow the safety rules in this
operator’s manual, the unit is safe to operate.
The mower deck has spinning mower blades that can
amputate hands and feet. Do not allow anyone near the unit
while it is running! Keep safety devices (guards, shields,
and switches) in place and working.
Specifications
To help you, the operator, use this equipment safely, it is
equipped with an operator-present safety system. Do NOT
attempt to alter or bypass the system. See your dealer
immediately if the system does not pass all the safety
interlock system tests found in this manual.

Operator Safety
Roll Bar Use
Keep the roll bar in the raised position and fasten the seat
belt. There is no roll over protection when the roll bar is
down! Do not jump off if the mower tips (it is safer to be
secured by the seat belt with the roll bar raised.)
Controls
Lower the roll bar only when necessary (such as to
temporarily clear a low overhanging obstacle) and NEVER
remove it. Do NOT use the seat belt when the roll bar is
down. Raise the roll bar as soon as clearance permits.
Retaining walls and drop-offs around steps and water are a common
hazard. Give yourself a minimum of two mower widths of clearance
around these hazards and hand-trim with a walk behind mower or
string trimmer. Wheels dropping over retaining walls, edges, ditches,
embankments, or into water can cause rollovers, which may result in
serious injury, death, or drowning.

Operation
WARNING
Towed Equipment (Ride-On Units)
Safety
Slopes are a major factor related to loss-of-control and tipover accidents, which can result in severe injury or death.
Operation on all slopes requires extra caution. If you cannot
back up the slope or if you feel uneasy on it, do not operate on
it.
Control of a walk-behind or ride-on machine sliding on a
slope will not be regained by the application of the brake. The
main reasons for loss of control are: insufficient tire grip on
the ground, speed too fast, inadequate braking, the type of
machine is unsuitable for its task, lack of awareness of the
ground conditions, incorrect hitching and load distribution.
1. Mow across slopes, not up and down.
2. Watch for holes, ruts, or bumps. Uneven terrain could
overturn the unit. Tall grass can hide obstacles.
3. Choose a slow speed so that you will not have to stop or
change speeds while on the slope.
4. Do not mow on wet grass. Tires may loose traction.
5. Avoid starting, stopping, or turning on a slope. If tires
lose traction (i.e. machine stops forward motion on a
slope), disengage the blade(s) (PTO) and drive slow off
the slope.
6. Keep all movement on slopes slow and gradual. Do not
make sudden changes in speed or direction, which could
cause the machine to rollover.
7. Use extra care while operating machines with grass
catchers or other attachments; they can affect the
stability of the unit. Do not use on steeps slopes.
8. Do not try to stabilize the machine by putting your foot
on the ground (ride-on units).
9. 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.
10. Do not use grass catchers on steep slopes.
11. Do not mow slopes if you cannot back up them.
12. See your authorized dealer/retailer for recommendations
of wheel weights or counterweights to improve stability.
13. Remove obstacles such as rocks, tree limbs, etc.
14. Use slow speed. Tires may lose traction on slopes even
though the brakes are functioning properly.
15. Do not turn on slopes unless necessary, and then, turn
slowly and gradually uphill, if possible. Never mow
down slopes.

Zero-Turn Driving Practice
The lever controls of the Zero Turn rider are responsive,
and learning to gain a smooth and efficient control of the
rider’s forward, reverse, and turning movements will take
some practice.
Operation
Controls
Spending some time going through the maneuvers shown
and becoming familiar with how the unit accelerates,
travels, and steers — before you begin mowing —is
absolutely essential to getting the most out of the Zero
Turn rider.
Locate a smooth, flat area of your lawn — one with
plenty of room to maneuver. (Clear the area of objects,
people and animals before you begin.) Operate the unit at
mid-throttle during this practice session (ALWAYS operate
at full throttle when mowing), and turn slowly to prevent
tire slippage and damage to your lawn.
We suggest you begin with the Smooth Travel procedure
to the right, and then advance through the forward,
reverse, and turning maneuvers.
You must release the parking brake prior to moving the
control levers inward.
Smooth Travel
The lever controls of the
Zero Turn rider are
responsive.
The BEST method of
handling the ground speed
control levers is in three
steps — as shown in Figure
7.
FIRST place your hands
onto the levers as shown.
SECOND, to go forward
gradually push the levers
forward with your palms.
THIRD, to speed up move
the levers farther forward.
To slow down smoothly,
slowly move the levers
toward neutral.

Forward Travel Practice
Reverse Travel Practice
Gradually move both ground speed control levers — evenly
FORWARD from neutral. Slow down and repeat.
LOOK DOWN & BEHIND, then gradually move both ground
speed control levers evenly BACK from neutral. Slow down
and repeat.
NOTE: Straight forward travel takes practice. If necessary,
top speed can be balance-adjusted — see the Speed
Balancing Adjustment in the Adjustments section near the
back of this manual.
Forward
Travel
NOTE: Practice backing up for several minutes before
attempting to do so near objects. The rider turns sharply in
reverse as well as forward, and backing up straight takes
practice.

Executing an End-Of-Row Zero Turn
Your Zero Turn Rider’s unique ability to turn in
place allows you to turn around at the end of a
cutting row rather than having to stop and Y-turn
before starting a new row.
For example, to execute a left end-of row zero
turn:
Troubleshooting
1. Slow down at the end of the row.
2. Move the RIGHT ground speed control lever
forward slightly while moving the LEFT ground
speed control lever back to center and then
slightly back from center.
3. Begin mowing forward again.
This technique turns the rider LEFT and slightly
overlaps the row just cut—eliminating the need to
back up and re-cut missed grass.
Specifications
As you become more familiar and experienced
with operating the Zero Turn rider, you will learn
more maneuvers that will make your mowing time
easier and more enjoyable.
Remember, the more you practice, the better your
control of the Zero Turn will be!

Tall Grass Requires Incremental Cutting
7. Stop the engine (see Stopping the Rider).
Mowing Recommendations
For extremely tall grass, set the cutting height at maximum
for the first pass, and then reset it to the desired height and
mow a second or third time.
Several factors can affect how well your machine cuts grass,
Following proper mowing recommendations can improve
the performance and life of your machine.
Don’t cover the grass surface with a heavy layer of
clippings. Consider using a grass collection system and
starting a compost pile.
Operation
5. Begin mowing. See Mowing Recommendations
section for tips on mowing patterns and lawn care.
See Troubleshooting section for information on
troubleshooting common cutting problems.
Height of Grass
Cut Here On
First Pass
Cut
Here On

Maintenance
Often cutting height is a matter of personal preference.
Typically, you should mow the grass when it is is between
three and five inches high. The proper cutting height
range for a specific lawn will depend upon several factors,
including the type of grass, the amount of rainfall, the
prevailing temperature, and the lawn’s overall condition.
Cutting the grass too short causes weak, thin grass plants,
which are easily damaged by dry periods and pests. Cutting
too short is often more damaging than allowing the grass to
be slightly higher.
Troubleshooting
Letting grass grow a bit longer—especially when it is hot
and dry—reduces heat build-up, preserves needed moisture
and protects the grass from heat damage and other
problems. However, allowing grass to grow too high can
cause thin turf and additional problems.
Figure 15. Incremental Cutting
Cutting off too much at one time shocks the plant’s growth
system and weakens the grass plants. A good rule of thumb
is the 1/3 rule: to cut no more than one third of the grass
height, and never more than 1 inch at a time.
Specifications
The amount of grass you are able to cut in one pass is
also effected by the type of mowing system you are using
(for example, broadcasting with side discharge decks can
process a much larger volume of grass than mulching
does).
23
Operation
Safety
When and How Often to Mow
The time of day and condition of the grass greatly affect the
results you’ll get when mowing. For the best results, follow
these guidelines:
Controls
1. Mow when the grass is between three and five inches
high.
2. Mow with sharp blades. Short clippings of grass one
inch or shorter decompose more quickly than longer
blades. Sharp mower blades cut grass cleanly and
efficiently, preventing frayed edges which harm the
grass.
3. Mow at time of day when the grass is cool and dry.
Late afternoon or early evening often provide these ideal
mowing conditions.
Where possible, make one or two passes around the outside
of the area discharging the grass INTO the lawn to keep the
cut grass off fences and walks.
Operation
4. Avoid mowing after rain or even heavy dew, and never
mulch when the grass is wet (moist grass does not
mulch well, and clumps beneath the mower deck).
Mowing Patterns
Always start mowing on a smooth, level area.
The size and type of area to be mowed will determine the
best mowing pattern to use. Obstructions such as trees,
fences and buildings, and conditions such as slopes and
grades must also be considered.
2. Where possible, change patterns occasionally to
eliminate matting, graining or a corrugated appearance.
3. For a truly professional cut, mow across the lawn in one
direction, then recut the lawn by mowing perpendicular
to the previous cut.
Mowing Methods
Note: Always operate the engine at full throttle when
mowing.
Broadcasting, or side-discharging, disperses fine clippings
evenly over the entire lawn. Many golf courses use this
method. Your mower has a deep dish deck to allow freer
circulation of clippings so they are broadcast evenly over the
lawn.
If you hear the engine slowing down, you are mowing
too fast—using a slower ground speed will improve the
cutting efficiency of the blades and prevents many common
cutting problems. Use an appropriate ground speed for the
thickness and height of the grass you are cutting (3rd gear
or slower for manual gear models). If you hear the engine
slowing down you are mowing too fast, use a slower ground
speed.
Proper Broadcast Mowing
Engine Speed & Ground Speed for Broadcasting
Always operate the engine at full throttle when mowing. If
you hear the engine slowing down, you are mowing too
fast—using a slower ground speed will improve the cutting
efficiency of the blades and prevents many common cutting
problems.
ALWAYS use an appropriate ground speed for the thickness
and height of the grass you are cutting (3rd gear or slower
for manual gear models). If you hear the engine slowing
down you are mowing too fast, use a slower ground speed.
Specifications
Troubleshooting
Maintenance
1. Cut long straight strips overlapping slightly.
The remainder of the mowing should be done in the
opposite direction so that the clippings are dispersed OUT
onto the area of lawn previously cut.
How Much Grass to Cut Off When Broadcasting
Mow when the grass is 3-5 inches long. Do not cut the
grass shorter than 2 to 2-1/2 inches. Do not cut off more
that 1 inch of grass in a single pass
24
www.simplicitymfg.com
Operation
Attaching a Trailer
Mulching consists of a mower deck which cuts and recuts
clippings into tiny particles and which then blows them
down INTO the lawn. These tiny particles decompose rapidly
into by-products your lawn can use. UNDER PROPER
CONDITIONS, your mulching mower will virtually eliminate
noticeable clippings on the lawn surface.
The maximum weight of a towed trailer should be less than
200 lbs (91kg). Secure the trailer with a appropriately sized
clevis pin (A, Figure 17) and clip (B).
NOTE: When mulching under heavy cutting conditions, a
rumbling sound may be present and is normal.
Mulching mowers cannot function properly if the grass is
wet, or if the grass is simply to high to cut. Even more than
normal mowing, mulching requires that the grass be dry and
the the appropriate amount is cut.
A
Operation
Do not use the mower as a mulching mower during the first
two or three mowings in the spring. The long grass blades,
quick growth, and often wetter conditions are more suitable
for broadcasting (side-discharging) or grass bagging
operation.
Engine Speed & Ground Speed for Broadcasting
B
Maintenance
Use full engine throttle matched with a slow ground speed
so that clippings will be finely cut. Ground speed while
mulching should be HALF of the speed that would be
used when broadcasting (side discharging) under similar
conditions. Since mulching requires more horsepower
than broadcasting, using a slower ground speed is vitally
important for proper mulching operation.
How Much Grass to Mulch
Figure 17. Trailer Weight Recommendations
A. Clevis Pin
B. Clip
Troubleshooting
The best mulching action typically results from cutting only
the top 1/2 inch to 3/4 inch of grass blade. This provides
short clippings which decompose properly (much more
quickly than longer clippings). The ideal cutting height will
vary with climate, time of year, and quality of your lawn. We
recommend that you experiment with both the cutting height
and ground speed until you achieve the best cut. Start with
a high cutting height and using progressively lower settings
until you find a cutting height that is matched to your
mowing conditions and preferences.
Controls
Mulching Requires EXCELLENT Mowing Conditions
Excessive towed loads can cause loss of traction and loss of
control on slopes. Reduce towed weight when operating on
slopes. The surface being driven on greatly impacts traction
and stability. Wet or slippery surfaces can greatly reduce

Troubleshooting
1. Warm engine by running for a few minutes. (Refer to
the engine operator’s manual for oil & filter replacement
instructions.)
2. Remove the oil drain hose (A, Figure 18) from the cable
clamp (B) on the right-hand side of the frame and route
the hose through hole in the engine deck as shown in
Figure 15.
3. Place a small pan under the oil drain hose to catch the
oil. Using the appropriate tools, remove the cap (B)
from the oil drain hose (A) and drain the engine oil.
4. After draining, replace the cap and wipe up any spilled
oil. Reinstall the oil drain hose into the cable clamp to
retain the hose during normal operation.
5. Place an absorbent shop cloth under the engine oil filter.
Remove the engine oil filter and replace with a new one.
6. Remove the shop cloth and wipe up any spilled oil.
Operation
The fuel filter is located in the fuel line between fuel tank and
carburetor, near the fuel pump. If filter is dirty or clogged,
replace as follows:
1. Disconnect the negative battery cable.
2. Place a container below the filter to catch spilled fuel.
3. Using a pliers, open and slide hose clamps from fuel
filter.
4. Remove hoses from filter.
5. Install new filter in proper flow direction in fuel line.
6. Secure with hose clamps.
7. Reconnect the negative battery cable when finished.
• Gasoline is highly flammable and must be handled with
care. Never fill the tank when the engine is still hot from
recent operation. Do NOT allow open flame, smoking or
matches in the area. Avoid over-filling and wipe up any
spills.
• Do NOT remove fuel filter when engine is hot, as spilled
gasoline may ignite. Do NOT spread hose clamps further
than necessary. Ensure clamps grip hoses firmly over
filter after installation.

5. Install the drive belt on the PTO pulley, the spindle
pulleys and all idler pulleys except the stationary pulley
(B, Figure 47).
6. Carefully rotate the breaker bar counter-clockwise and
install the belt on the stationary idler pulley (B).
7. Carefully release the tension on the breaker bar.
8. Run the mower under no-load condition for about 5
minutes to break-in the new belt.
C
Operation
Use extreme caution when rotating the idler arm with the
breaker bar, due to the increased tension in the spring
as the idler arm is being rotated. Injury may result in
the breaker bar is prematurely release while the spring is
under tension.

The gross power rating labels for individual gas engine models meet or exceed SAE (Society of Automotive Engineers)
code J1940 (Small Engine Power & Torque Rating Procedure) and rating performance has been obtained and corrected in
accordance with SAE J1995 (Revision 2002-05). Actual gross engine power may be lower and is affected by, but not limited
to, ambient operating conditions and engine to engine variability. Given both the wide array of products on which engines
are placed, and the variety of environmental issues applicable to operating the equipment, the gas engine will not develop the
rated gross power when used in a given piece of power equipment (actual “on-site” or net horsepower). This difference is due
to a variety of factors including, but not limited to, accessories (air cleaner, exhaust, charging, cooling, carburetor, fuel pump,
etc.), application limitations, ambient operating conditions (temperature, humidity, altitude), and engine to engine variability.
