OPERATING INSTRUCTIONS 

If you are not completely familiar with the Safety Instruction 
Manual read it now before proceeding with the operation of 
the mower.  REMEMBER THERE ARE CERTAIN 
PRECAUTIONS LISTED IN THIS MANUAL THAT YOU MUST 
NOW TAKE BEFORE STARTING THE MOWER. 

    

WARNING

 

Inspect Mower Before Each Use:

 

Inspection of Mower:

  Do not use the mower if 

any parts are not maintained in good operating 
condition.  Examine all moving parts prior to 
each use.  Look for excessive wear, bald drive 
tires or worn out front tires (normally smooth), 
cracks in parts, loose or missing bolts, cotter, 
linchpin or “hair” pins or cable yoke pins and 
replace before operating the mower.  Make 
sure all safety equipment provided with the 
mower is in good operating order, including all 
warning decals and the operator-presence 
device which stops the engine and blades when 
the foot-operated Operator Presence Control 
(OPC) switch is released.  To test the OPC, 
follow the instructions given later in this manual.  
Inspect the two anti-tip rollers and their 
respective bolts at the rear of the mower for 
tightness and proper operation.  Ensure that all 
parts of the Quad Lever™ control system are 
tight and secure.  This is to reduce the 
possibility that the mower could have a loss of 
control or safety. 
 

Basic Operation:

  The following procedures 

are to guide you through the basic operation of 
the mower.  You should be a qualified mower 
operator according to the safety section of this 
manual.  If this is your first time, operation 
should only be done with the assistance of your 
dealer on a level area.  You should go through 
each step, in the order indicated, every time 
you start the mower. 
 

How to start the mower: 

Before starting the engine 

 

• Make sure the control levers are in the 

exact neutral position 

 

• Apply the parking brake if it is not already 

set. 

 

• Turn OFF the blade engaging switch if it is 

on. 

 

• Turn fuel valve toward tank with fuel in it. 

 

Starting the engine

 

Electric Start: 
•Start the engine according to the engine 

manufacturer’s recommendation, see 
engine manual.  Set the throttle control lever 
near mid throttle, pull out on the choke 
control knob and turn the key to the start 
position.  Do not engage the starter for more 
than ten (10) seconds at a time.  This may 
overheat the starter and the wiring systems.  
Wait ten (10) seconds between attempts.  If 
the engine does not start within ten tries or 
stalls frequently, take the mower in for 
service. 

After starting the engine according to the 
engine manufacturer’s recommendation, push 
in on the choke control knob to open the choke 
valve, let the engine run for several minutes to 
get the hydraulic fluid circulating through the 
pumps, etc. and to allow the engine to warm up.  
Do not over-rev a cold engine. 
 

Unusual noises or irregular operation:

 

As you drive the mower, listen for any unusual 
noises and test for irregular operation and 
adjust or service as necessary. 
 

How to drive the mower:

 

While sitting or standing, both feet should be 
firmly placed on the foot platform.  Set the 
engine speed about a fourth of the way from 
idle.  Release the parking brake.  Now try 
moving the hand control levers, one at a time, 
very slightly, forward and backward.  Check to 
see if the wheels move forward and backward 
according to the position of the levers.  (If not, 
check to see that the pump release valves are 
closed.)  With both feet still firmly placed on the 
foot platform, increase the engine speed to 
about half of the way from idle speed.  Release 
the parking brake.  The higher engine speed 
will make the controls much more responsive 
and the mower much quicker; Use caution if it is 
your first time.  Now try moving the hand control
