The SmartSwitch Ignition is programmed with warning lights 

to indicate when any part of the safety system is not being 

followed.  The engine will not start until all the following 

ignition system faults are resolved:
•  The park brake symbol (CC) will be lit if the parking 

brake has not been engaged during a start attempt.

• 

The blade switch symbol (EE) will blink if the attachment 

clutch control is not in the "DISENGAGED" position 

during a start attempt. 

STARTING
The Briggs & Stratton Endurance engine equipped with 

your tractor features a Ready-Start automatic choke system 

to provide simplified starting in normal conditions.  Please 

read the following starting instruction carefully.
NOTE: For the first time starting after your tractor has sat 

for an extended period of time, or after running out of gas, 

the engine may require an extended start attempt to reprime 

the fuel system.  For an extended start, press and hold 

SSI button for three seconds before releasing.  This will 

prompt the engine to attempt starting for up to ten seconds 

(instead of the normal five seconds), allowing time for fuel 

to be pulled into the engine.

NORMAL STARTING (32°F/0°C and above)
1.  Move throttle control to fast position (

).

2.  Perform procedures outlined in "S

the fast position (

) to warm-up.  The time required 

for warm-up will vary from a few seconds to a minute 

depending upon conditions and temperature.

•  Leave throttle control in fast position (

) while 

mowing.

NOTE: Failure to move throttle from cold weather starting 

position (

) will result in poor engine performance and 

spark plug fouling.

AUTOMATIC TRANSMISSION WARM UP
•  Before driving the unit in cold weather, the trans mis sion 

should be warmed up as follows:
•  Ensure the tractor is on level ground.
•  Release the parking brake and let the brake slowly 

return to operating position.

•  Allow one minute for transmission to warm up. This 

can be done during the engine warm up period.

•  The attachments can also be used during the engine 

warm-up period after the transmission has been warmed 

up.

PRE-START

Ensure freewheel control is in the transmission en gaged 

position.
