SAFETY PRECAUTIONS AND DECALS  
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 is capable of amputating hands and  
feet, and throwing objects. Failure to observe the following safety instructions could  
result in serious injury or death.  
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 accidentally 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. Keep clear of the discharge  
opening at all times.  
Do not mow in reverse. Always look down and behind before and while backing.  
Turn off the blades when not mowing. Before leaving the machine, turn off the  
blades and stop the engine.  
Watch for traffic when operating near or crossing roadways.

Turn off the blades when not mowing. Before leaving the machine, turn off the  
blades 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.  
Do not operate the machine while under the influence of alcohol or drugs.  
Operate self-propelled machines up and down slopes. There is significant risk of  
overturns when operating across slopes. Operate walk-behind machines across  
slopes. There is a significant risk of slipping under a walk-behind machine when  
operating up and down slopes.  
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.

OD45 – WARNING DECAL  
D55 – DANGER DECAL  
D29 – SPINNING BLADE DECAL  
OPERATING YOUR NEW CUTTER  
The operation of any cutter 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 before starting any cutting machine and while operating such  
a machine.  
The operation of any cutter 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 CUTTER (Cont)  
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-  
1/2” in diameter or less.  
PROPULSION  
The Predator is self-propelled, and is controlled by a “GROUND CONTROL” bail. To  
engage the drive, put the transaxle in a gear and activate the lower bail. Releasing the  
bail 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” bail, placing the transaxle in neutral, and pushing the machine.  
TRAVEL 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 blades engaged. To shift the cutter into reverse, release  
“GROUND CONTROL” bail, disengage blade, and rotate the shift lever to the left.  
Blade  
When the lever stops lift up and continue to turn it to the left until it stops again.  
will not engage while cutter is in the “reverse” gear.  
BLADE ENGAGE  
An “OPERATOR PRESENCE” bail and a “BLADE ENGAGE” lever control engaging  
the Predator’s blade. Both devices must be activated before the blade will work.  
Releasing the “OPERATOR PRESENCE” bail will disengage both the blade and the  
“BLADE ENGAGE” lever.  
STARTING THE ENGINE  
See engine manufacturer’s instructions for the type and amount of oil and fuel  
used. Engine must be level to accurately check and fill oil.  
Make sure unit is level, blades disengaged, and transaxle in “NEUTRAL”.  
Check spark plug wire, oil, and fuel.  
Turn key switch to the “ON” position.  
Set engine idle to the “CHOKE” position.  
With feet clear of cutter deck, pull engine coil rope. Do not pull rope recklessly.  
Set engine speed by moving “CHOKE” to the desired RPM.

STOPPING  
Bring cutter to a complete stop.  
Disengage the blade.  
Place transaxle in the “NEUTRAL” position.  
Turn key to “OFF” position.  
Remove keys to avoid irresponsible usage.  
CUTTER HEIGHT ADJUSTMENT  
There are two height settings.  
Place two 6” wooden blocks under the deck on the side being adjusted.  
Remove nuts and bolts from the side runner.  
Slide runner to the other position.  
Replace the nuts and bolts making certain they are secure.  
Repeat to other side. Runners should be at the same height.  
BREAKING IN YOUR CUTTER  
Start engine properly.  
Slowly, engage blade control.  
Under supervision, allow blades to rotate and engine to idle for 5 minutes.  
Disengage blades.  
Shift through each gear. While in each gear engage the “GROUND CONTROL”  
and travel 20 yards to ensure transaxle works properly.  
CAUTION!  
CAUTION!  
Chock wheels  
when parking  
on a hillside.  
Disconnect spark  
plug wire and place  
the wire where it  
cannot connect the  
spark plug before  
servicing unit.  
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, setting desired engine speed.  
Slowly, engage blade.  
Move transaxle into low gear and activate “GROUND CONTROL” bail.  
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.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
BACKING UP  
Disengage blade.  
Check safety behind you.  
Move transaxle into “REVERSE” position.  
Activate “GROUND CONTROL” bail.  
TRANSPORTING  
Disengage blade.  
Shut off engine and remove keys.  
Using 3 persons to lift cutter is recommended.  
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 out. 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.
