Cub Cadet LTX1042KW User Manual

This tractor is equipped with a safety interlock system for the 

protection of the operator. If the interlock system should ever 

malfunction, do not operate the tractor. Contact your Cub Cadet 

dealer.
• 

The safety interlock system prevents the engine from 

cranking or starting unless the parking brake is engaged, 

and the PTO (Blade Engage) knob is in the disengaged 

(OFF) position.

• 

The engine will automatically shut off if the operator leaves 

the seat before engaging the parking brake.

• 

The electric PTO (Blade Engage) clutch will automatically 

shut off if the operator leaves the tractor’s seat with the 

PTO (Blade Engage) knob in the engaged (ON) position, 

regardless of whether the parking brake is engaged.

• 

With the ignition key in the NORMAL MOWING position, 

the electric PTO (Blade Engage) clutch will automatically 

shut off if the PTO (Blade Engage) knob is moved into the 

engaged (ON) position with the drive pedal in position for 

reverse travel.

Do not operate the tractor if the 

interlock system is malfunctioning. This system was 

designed for your safety and protection. 

 

NOTE: Refer to the Assembly & Set-Up section of this manual for 

Gasoline and Oil fill-up instructions.
1. 

Insert the tractor key into the ignition switch module.

2. 

Place the PTO (Blade Engage) knob in the disengaged (OFF) 

position.

3. 

Engage the tractor’s parking brake.

4. 

On some models, activate the choke control by moving the 

throttle/choke control all the way forward into the choke 

position. On other models, pull the Choke Control Knob 

outward to activate the choke with the throttle control 

moved midway between its SLOW and FAST positions. 
NOTE: If the engine is warmed up, it may not be necessary 

to place the choke control in the choke position.

5. 

Turn the ignition key clockwise to the START position. 

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

NORMAL MOWING position.

Do NOT hold the key in the START 

position 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.

NOTE: Do NOT leave the choke on while operating the tractor. 

Doing so will result in a “rich” fuel mixture and cause the engine 

to run poorly.

If you strike a foreign object, stop the 

engine and disconnect the spark plug wire(s). 

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 

knob in the disengaged (OFF) position.

2. 

Place the throttle control near the SLOW position.

3. 

Turn the ignition key counterclockwise to the STOP 

position.

4. 

Remove the key from the ignition switch to prevent 

unintended starting.
