Starting the Engine

WARNING: 

Do not operate the tractor if 

the interlock system is malfunctioning. 
This system was designed for your safety 
and protection.

NOTE

Refer to the 

SETTING UP

 YOUR LAWN TRAC-

TOR on page 8 of this manual for Gasoline and Oil fill-up 
instructions. 

IMPORTANT

: Your tractor is shipped with motor oil in the 

engine. However, you MUST check the oil level before 
operating. Be careful not to overfill. Refer to the Engine 
Operator’s Manual included with this unit for complete 
instructions for checking and filling the motor oil.
1.  Insert the tractor key into the ignition switch.
2.  Place the PTO (Blade Engage) lever in the disen-

gaged (OFF) position.

3.  Engage the tractor’s parking brake.
4.  Activate the choke control.
5.  Turn the ignition key clockwise to the START position. 

After the engine starts, release the key. It will return to 
the ON position.

IMPORTANT

: Do NOT hold the key in the START posi-

tion for longer than ten seconds at a time. Doing so may 
cause damage to your engine’s electric starter.
6.  After the engine starts, deactivate the choke control 

and place the throttle control in the FAST position.

NOTE

Do NOT leave the choke control on while operat-

ing the tractor. Doing so will result in a “rich” fuel mixture 
and cause the engine to run poorly. 

Stopping the Engine

WARNING: 

If you strike a foreign object, 

stop the engine, disconnect the spark plug 
wire(s) and ground against the engine. 
Thoroughly inspect the machine for 
any damage. Repair the damage before 
restarting and operating

1.  If the blades are engaged, place the PTO (Blade 

Engage) lever in the disengaged (OFF) position.

2.  Turn the ignition key counterclockwise to the STOP 

position. 

3.  Remove the key from the ignition switch to prevent 

unintended starting.

Operating 

Your Lawn 

Tractor

WARNING

Do not operate the 

tractor if the interlock 

system is malfunction-

ing. This system was 

designed for your 

safety and protection.

If you strike a foreign 

object, stop the 

engine, disconnect 

the spark plug wire(s) 

and ground against 

the engine. Thoroughly 

inspect the machine 

for any damage. Repair 

the damage before 

restarting and operat-

ing.

Driving The Tractor

WARNING: 

Avoid sudden starts, ex-ces-

sive speed and sudden stops.

WARNING: 

Do not leave the seat of the 

tractor without first placing the PTO (Blade 
Engage) lever in the disengaged (OFF) 
position, depressing the brake pedal and 
engaging the parking brake. If leaving the 
tractor unattended, also turn the ignition 
key off and remove the key.

1.  Depress the brake pedal to release the parking brake 

and let the pedal up. 

2.  Move the throttle lever into the FAST (rabbit) position.

IMPORTANT

: Do NOT use the shift lever to change the 

direction of travel when the tractor is in motion. Always 
use the brake pedal to bring the tractor to a complete 
stop before shifting.
3.  To move forward, place the shift lever in the FOR-

WARD position, then slowly depress the drive pedal 
until the desired speed is achieved.

4.  To move in reverse, place the shift lever in the 

REVERSE position, check that the area behind is 
clear then slowly depress the drive pedal.

Driving On Slopes

Refer to the SLOPE GAUGE on page 3 to help determine 
slopes where you may operate the tractor safely.

WARNING: 

Do not mow on inclines with 

a slope in excess of 15 degrees (a rise of 
approximately 2-1/2 feet every 10 feet). The 
tractor could overturn and cause serious 
injury.

•  Mow up and down slopes, NEVER across.
•  Exercise extreme caution when changing direction on 

slopes.

•  Watch for holes, ruts, bumps, rocks, or other hidden 

objects. Uneven terrain could overturn the machine. 
Tall grass can hide obstacles.

•  Avoid turns when driving on a slope. If a turn must be 

made, turn down the slope. Turning up a slope greatly 
increases the chance of a roll over.

•  Avoid stopping when driving up a slope. If it is 

necessary to stop while driving up a slope, start up 
smoothly and carefully to reduce the possibility of 
flipping the tractor over backward.

Do not leave the seat 

of the tractor without 

first placing the PTO 

(Blade Engage) lever in 

the disengaged (OFF) 

position, depressing 

the brake pedal and 

engaging the parking 

brake. If leaving the 

tractor unattended, 

also turn the ignition 

key off and remove the 

key.
