manufactured to meet or exceed all industry standards for

safety.

Do not operate this machine unless you have been trained.

Reading and understanding this operator’s manual is a way to

train yourself.

Power equipment is only as safe as the operator. If it is

misused, or not properly maintained, it can be dangerous!

Remember, you are responsible for your safety and that of

those around you.

Use common sense, and think through what you are doing.

If you are not sure that the task you are about to perform can

be safely done with the equipment you have chosen, ask a

professional: contact your local authorized dealer.

Read the Manual

The operator’s manual contains important safety information

you need to be aware of BEFORE you operate your unit as

well as DURING operation.

Safe operating techniques, an explanation of the product’s

features and controls, and maintenance information is

included to help you get the most out of your equipment

investment.

Be sure to completely read the Safety Rules and Information

found on the following pages. Also completely read the

Operation section.

Children

Tragic accidents can occur with children. Do not allow them

anywhere near the area of operation. Children are often

attracted to the unit and mowing activity. Never assume that

children will remain where you last saw them. If there is a risk

that children may enter the area where you are mowing, have

another responsible adult watch them.

Slope Operation

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 15 degrees (a 5.4 foot rise

over a 20 foot length).

Avoid turning down slopes; if possible turn up slopes. 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.

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.

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

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.

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.

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.)

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, Drop-Offs and Water

Retaining walls and drop-offs around steps and water are

a common hazard. Do NOT operate down slope towards or

near water, retaining walls, or drop-offs.

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.

Overhead Obstacles

Check for overhead clearances before driving under any

objects. Do not allow the roll bar to contact low overhanging

obstacles such as tree branches and guide wires.

Fuel and Maintenance

Always disengage all drives, shutoff the engine, and remove

the key before doing any cleaning, refueling, or servicing.

Gasoline and its vapors are extremely flammable. Do not

smoke while operating or refueling. Do not add fuel while

engine is hot or running. Allow engine to cool for at least 3

minutes prior to adding fuel.

Do not add fuel indoors, in an enclosed trailer, garage, or any

other enclosed area that is not well ventilated. Gasoline spills

should be cleaned up promptly and before operation begins.

Gasoline should be stored only in sealed containers approved

for fuel.

Proper maintenance is critical to the safety and performance

of your unit. Keep the unit free of grass, leaves, and excess

oil. Be sure to perform the maintenance procedures listed in

this manual, especially periodically testing the safety system.

Enclosed Areas

Not for

How to measure the slope of a lawn surface with a

smartphone or an angle finder tool:

WARNING

Do not operate on slopes greater than15degrees.

1. Use a straight edge at least two (2) feet long (A,

Figure2). A 2x4 or a straight piece of metal works well.

2. Angle finder tools.

a. Use your smartphone:Many smartphones (B,

Figure2) have an inclinometer (angle finder) located

under the compass application (app). Or, search an

app store for an Inclinometer app.

b. Use angle finder tools:Angle finder tools (C and

D, Figure2) are available at local hardware stores

or online (also called inclinometer, protractor, angle

meter, or angle gauge). Dial type (C) or digital type

(D) work, others may not.Read and obey the user

instructions supplied with the angle finder tool.

3. Put the two (2) feet long straight edge along the steepest

part of the lawn slope. Put the board up and down the

slope.

4. Lay the smartphone or angle finder tool on the straight

edge and read the angle in degrees. This is the slope of

your lawn.

be replaced. Small undetectable cracks can reduce the

effectiveness of the ROLL BAR. Never weld, straighten,

or repair the ROLL BAR.

• Never alter the ROLL BAR by welding anything to it or by

drilling additional holes.

• BEFORE FIRST TIME USE - Inspect the ROLL BAR

structure and mounting hardware for:

1) Check to make sure the machine GVW (Gross Vehicle

Weight), including attachments, restrained payload, fuel

and operator, is not in excess of the maximum weight

specified on the ROLL BAR label.

2) Make sure there isn’t any missing, damaged, or loose

mounting hardware.

3) Make sure the ROLL BAR has been correctly and

completely installed.

• EVERY 100 HOURS - Inspect the ROLL BAR structure

and mounting hardware for:

1) Any cracks in the structure (structural members and/or

welds).

2) Significant corrosion on any part of the ROLL BAR

structure or hardware.

3) Missing, damaged, or loose mounting hardware

4) Mounting hardware that is of a grade lesser than

specified.

5) Machine GVW (Gross Vehicle Weight), including

attachments, restrained payload, fuel and operator, in

excess of the maximum weight specified on the ROLL

BAR label.

6) Any modifications that have been made, such as

unauthorized welds and holes.

7) Any permanent deformation or twisting of the ROLL

BAR structure.

8) That the ROLL BAR label is still in place and is

readable.

9) That the ROLL BAR on-product warning labels are still

on the ROLL BAR and are readable.

• If there is any doubt as to the condition of the ROLL BAR,

remove the machine from service and contact your dealer

for assistance.

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.

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 12.

12

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.

Basic Driving

Forward Travel Practice

Not for

Reproduction

19

13

Gradually move both ground speed control levers — evenly

FORWARD 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.

Reverse Travel Practice

14

LOOK DOWN & BEHIND, then gradually move both ground

speed control levers evenly BACK from neutral. Slow down

and repeat.

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.

Practice Turning Around A Corner

15

While traveling forward allow one handle to gradually return

back toward neutral. Repeat several times.

NOTE: To prevent pivoting directly on the tire tread, it is best

to keep both wheels going at least slightly forward.

Practice Turning in Place

16

To turn in place, “Zero Turn,” gradually move one ground

speed control lever forward from neutral and one lever back

from neutral simultaneously. Repeat several times.

NOTE: Changing the amount each lever is pulled—forward or

back, changes the “pivot point” you turn on.

Advanced Driving

Executing an End-Of-Row Zero Turn

Not for

Reproduction

20 snapperpro.com

17

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:

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.

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!

Mowing

1. Engage the parking brake. Make sure that the PTO

switch is disengaged, the ground speed control levers are

locked in the NEUTRAL position and the operator is in the

seat.

2. Start the engine. See Starting the Engine.

3. Set the mower cutting height.

4. Set the throttle to the 1/2 throttle position.

Note:It is best practice to engage the PTO with the throttle

set at the minimum throttle position necessary to engage the

deck drive system without stalling the engine.

5. Engage the PTO by pulling up on the PTO switch.

6. Move the throttle to the "FAST" position and begin

mowing.

7. When finished, reduce throttle speed so that the engine

idles and push the PTO switch down to shut off the PTO.

8. Stop the engine. See Stopping the Rider.

Mowing Recommendations

Several factors can affect how well your machine cuts grass,

Following proper mowing recommendations can improve the

performance and life of your machine.

Height of Grass

Often cutting height is a matter of personal preference.

Typically, you should mow the grass when it 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.

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.

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.

18

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).

Tall grass requires incremental cutting. For extremely tall

grass, set the cutting height at maximum for the first pass (A,

Figure 19), and then reset it to the desired height and mow a

second (B) or third time.

Don’t cover the grass surface with a heavy layer of clippings.

Consider using a grass collection system and starting a

compost pile.
