SAFETY PRECAUTIONS
This Safety Alert Symbol indicates important messages in this
manual. When you see this symbol, carefully read the message that
follows and be alert to the possibility of personal injury.
Read this manual completely. This machine can amputate hands and feet, and
throw objects. Failure to observe the following safety instructions could result in
serious injury or death.
Thank you for choosing Swisher’s 24” Walk Behind Rough Cut. Before
operating your Walk Behind, please read, understand and follow all of the safety
precautions and other instructions explained in this manual. As with all power
equipment, lawn mowers can be potentially dangerous if not properly used.
3
• Read the manual. Learn to operate this machine safely.
• Always disconnect the spark plug wire and place the wire where it cannot contact the
spark plug, to prevent accidental starting the engine when setting up, transporting,
adjusting or making repairs.
• Keep all shields and guards in place.
• Understand the speed, steering and stability of this machine. Know the positions and
operations of all controls before you operate this machine. Check all of the controls in
a safe area before starting to work with this machine.
• Allow only responsible adults who are familiar with these instructions to operate this
machine. Never allow children to operate this machine.
• Clear the area of objects such as rocks, toys, wire, etc. that can be picked up and
thrown by the blade.
• Be sure the area is clear of other people before mowing. Be aware of the mower
discharge direction and do not point at anyone. Stop the machine if anyone enters the
mowing area. Children are often attracted to the machine and the mowing activity.
Never assume that children will remain where you last saw them. Keep children
under the watchful care of another responsible adult.
•No riders!
• Do not put hands or feet near or under rotating parts.
• Do not mow in reverse. Always look down and behind before and during backing.

• Turn off the blade when not mowing. Before leaving the machine, turn off the blade
and stop the engine.
• Watch for traffic when operating near or crossing roadways.
• Do not operate the mower if it has been dropped or damaged in any manner or if the
mower vibrates excessively. Excessive vibration is an indication of damage. Repair mower
as necessary.
• Dress properly. Do not operate the mower when barefoot or wearing open sandals. Wear
only solid shoes with good traction when mowing.
• Never allow operation by untrained persons.
• Do not operate the machine while under the influence of alcohol or drugs.
• Do not operate on slopes greater than 15 degrees.
• Never tamper with safety devices. Check their proper operation regularly.
• Stop and inspect the equipment if you strike an object. Repair, if necessary, before
restarting. Never make adjustments or repairs with the engine running.
• Mower blades are sharp and can cut. Wrap the blades or wear gloves, and use extra
caution when servicing them.
• Do not operate at too fast a rate.
• Disengage spark plug wire and place where it cannot make a connection.
• Check engine oil. All engines are filled with oil at the factory. Verify oil level and
add if necessary before starting engine (See Engine Owner’s Manual).
• Verify fuel level and add if necessary before starting engine.
• Reconnect spark plug wire.
• Refer to pages 5-7 in this manual for proper operating procedures.
PRE-OPERATING INSTRUCTIONS
4

The operation of any mower can produce foreign objects to be thrown into the
eyes, resulting in severe eye damage. Always wear certified safety glasses or
wide-vision safety goggles over spectacles before starting any cutting machine and
while operating such a machine.
The operation of any mower produces sound waves that are damaging to the
human ear. Ear protection is recommended.
CAUTION!
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 children will remain where you last saw them.
OPERATING YOUR NEW WALK BEHIND
INTENDED USE
This is not a lawn mower. The Predator is designed for cutting overgrown brush, weeds,
and other types of organic growth. This unit is capable of clearing small saplings of 1.5”
in diameter or less.
TRAVEL SPEED
Speed can be varied by choosing a higher or lower gear using the gearshift lever at the
rear of the machine or by changing the engine speed with the engine throttle. Do not
adjust speed with the blade engaged. To shift the cutter into reverse, release the
“GROUND CONTROL” lever, disengage the blade, and rotate the shift lever to the left.
When the lever stops, lift up the reverse lockout latch and continue to move the shift
lever to the left until it stops again.
PROPULSION
The Predator is self-propelled and is controlled by a “GROUND CONTROL” lever. To
engage the drive, shift the transaxle to a gear and activate the left lever by squeezing it
against the handle. Releasing the lever will disengage the self-propel.
Under most conditions cutting should be done in a low gear (1st or 2nd). Upper gears
should be used for conditions where weeds and brush are thinned out or not as tall. In
confined areas the machine can be pushed forwards or backwards by releasing the
“GROUND CONTROL” lever, shifting the transaxle to neutral, and pushing the
machine.
ENGAGING BLADE
An “OPERATOR PRESENCE” lever and a “BLADE ENGAGE DRIVE” control work
together to engage the Predator’s blade. Both devices must be activated before the blade
will work. Releasing the “OPERATOR PRESENCE” lever will disengage both the blade
and the “BLADE ENGAGE DRIVE” control.
5

STARTING THE ENGINE
See engine manufacturer’s recommendations for the type and amount of oil and fuel used.
Engine must be level to accurately check and fill oil. Do not overfill.
• Make sure unit is level, blade is disengaged, and transaxle in “NEUTRAL”
• Check spark plug wire, oil level, and fuel level.
• Check all electrical connections for build-up of debris.
• If needed set “CHOKE” to choke position.
• Flip the engine control switch to “ON” position.
• Set engine throttle control to ½ throttle position.
• Pull rope with a single fluid motion.
• After engine has started set “CHOKE” to “RUN” position.
STOPPING
• Bring the Walk Behind to a complete stop by releasing the “GROUND CONTROL”
lever. (left).
• Disengage mower blade by releasing the BLADE ENGAGE DRIVE” control (right).
• Reduce engine idle speed, and allow engine to run momentarily for cooling.
• Place transaxle in the “NEUTRAL” position.
• Flip the engine control switch to “OFF” position.
HEIGHT ADJUSTMENT
• Place two 6” wooden blocks under the deck on the side being adjusted.
• Remove nuts and bolts from the side runner.
• Slide skid up or down to preferred position.
• Replace the nuts and bolts making certain they are tightened securely.
• Repeat for the other side. Runners should be at the same height.
BREAKING IN YOUR WALK BEHIND
• Start engine properly.
• Slowly engage blade control.
• Under supervision, allow blade to rotate and engine to idle for 5 minutes.
• Disengage blade.
• Shift through each gear. While in each gear engage the “GROUND CONTROL” lever
and travel 20 yards to ensure transaxle works properly.
BEGIN CUTTING
• Make sure area is clear of all bystanders.
• Make sure that all guards, belt guides, and the spark plug wire are properly attached.
• Start engine, set engine throttle control at maximum engine idle speed for best results.
• Allow engine to run a few moments and slowly engage blade.
• Move transaxle into low gear and activate “GROUND CONTROL” lever.
• Turning is done by rotating the handles left or right. This machine has significant
weight and may take more effort to turn than one may expect. Turning could take
practice.
BACKING UP
• Disengage blade.
• Check behind you for safety.
• Move transaxle into “REVERSE” position.
• Activate “GROUND CONTROL” lever.

IMPORTANT: This engine may not be equipped with a spark arrester muffler. It is a violation of
California Public Resource Code Section 4442 to use or operate the engine on any forest-covered,
brush-covered, or grass-covered land. Other states or federal areas may have similar laws.

TRANSPORTING
• Shut off engine.
• Secure in place while unit is being transported.
• Unit should be left in low gear to avoid any slight rolling.
SUGGESTED PRACTICES
• Always operate engine at full throttle when cutting to assure the best cutting
performance and proper discharge of material.
• If grass is wet, allow it to dry. Wet grass clumps will collect on the bottom of the
deck.
• Go slow when cutting dense areas. Some dense areas may need to be gone over
twice. Better results occur if the second cut is 90 degrees to the first cut.
BEFORE EACH SEASON
A new spark plug and clean air filter assure proper air-fuel mixture and help your engine run
better and last longer.
• Replace the spark plug.
• Clean or replace the air filter.
• Check blades and belts for wear.
BEFORE EACH USE
• Check engine oil level. Do this twice to ensure an accurate reading.
• Check condition of air filter and clean or replace if necessary.
• Check blade operation.
• Check for loose fasteners.
DAILY MAINTENANCE
Make sure all nuts and bolts are tight and cotter pins and retainer springs are secure.
Keep blades sharp. Observe all safety precautions.
BLADE CARE AND SERVICE
For best results blades must be kept sharp. The blades can be sharpened with a few strokes of a
file or grinding wheel. Do Not attempt to sharpen blades while they are on the machine.
Important: Replace blades that have been damaged or deeply nicked.
Important: Check blade and spindle hardware on a regular basis to make sure nuts are
tight.
