d.

Turn the electric blade clutch switch “Off”.

e.

Push the throttle control to a position a 
third of the way between slow and fast.

f.

Insert the key in the ignition and start 
switch and turn the switch to “On”.

g.

Gasoline Engine: If the engine is cold, 
push the choke to the on position.

h.

Turn the ignition key in a clockwise direc-
tion to the “Start” position until the engine

Note:

 

Do not hold the key in the “Start”

again.

4.

Operating the Mower: Operating a zero-turn-
ing-radius mower is not like operating a trac-
tor-type riding mower. The zero-turning-radius 
mower is much more maneuverable and 
much less fatiguing to operate. However, get-
ting used to the fingertip control of the zero-
turning-radius mower takes some practice. 
We strongly recommend that you locate a 
“test area” where you can operate the mower 
for about 30 minutes without being disturbed.

a. Get into the operator’s seat.
b.

Start the engine.

c.

Use the transport lever to raise the mowing 

deck to the transport position. Make sure 
the blade clutch switch is off.

d. After the engine has warmed, adjust the 

throttle to the fast position.

e.

Release the parking brake.

f.

Fold in the steering levers to the operating 

position.

WARNING:

When operating this mower forward, do not
allow the steering levers to return to the neu-
tral position on their own. Always maintain a
firm grip on the steering levers, operate them
smoothly and avoid any sudden movements of
the levers when starting or stopping.

g.

To go forward, move both steering levers 
slightly forward and the mower will slowly 
move forward. The farther you move the 
levers forward the faster the mower will go 
forward.

h.

To back up, move both steering levers 
slightly backward and the mower will slowly 

move backward. The farther you move the 
levers backward the faster the mower will 
go backward.

i.

To turn, pull the lever back on the side to 
which you want to turn. The farther back 
you pull the lever, the faster and more 
sharply you will turn. Initially, you will have 
to be careful to avoid turning to fast and 
too far.

j.

After you have mastered operating the 
mower, use the transport lever to lower the 
mowing deck to the cutting position and 
pull on the electric blade clutch switch to 
start the blades rotating.

k.

Practice mowing in straight passes. When 
you feel confident, slowly practice mowing 
around obstacles such as trees.

5.

Parking the Mower:

a.

Push off the electric blade clutch switch.

b.

Use the Deck Lift Handle to raise the mow-
ing deck to the transport position.

c.

Drive the mower to the cleanup or storage 
area.

d.

Move the throttle to slow.

e.

Place the steering levers in the neutral 
position.

f.

Set the parking brake.

g.

Turn off the ignition switch and take the key 
from the switch.

h.

Close the fuel shutoff valves.

MAINTENANCE AND
SERVICE

sion of the springs will go from the deck to the 
lift handle. Not capturing the lift handle while
