The Cub Cadet XT2 LX42 is a compact lawn tractor with a liquid-cooled V-twin engine and hydrostatic transmission. Its instrument cluster provides essential warning lights to help you monitor key systems during mowing or towing.
Cub Cadet XT2 LX42 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A serious fault has been detected in the engine, transmission, or electrical system, demanding immediate engine shutdown to prevent damage. | Stop the engine safely as soon as possible, then consult the operator's manual or contact a Cub Cadet dealer. | |
| Check Engine (MIL) | AMBER | The engine control module has detected a problem with the emissions or performance system on your XT2 LX42. | Contact your Cub Cadet dealer for diagnostic service; you may continue mowing at reduced speed if no drivability issues. | |
| Engine Oil Pressure | RED | Engine oil pressure has dropped below safe levels, risking severe engine wear or seizure on your XT2 LX42. | Immediately shut off the engine and check the oil level; if low, add oil and restart; if light stays on, do not run the engine. | |
| Battery / Charging | RED | The charging system is not supplying voltage to the battery, which may cause the battery to drain and stop electrical functions on your tractor. | Check battery connections and alternator belt; if still on, have the charging system tested by a dealer. | |
| Coolant Temperature | RED | Engine coolant temperature has exceeded the safe limit, risking overheating and engine damage on your XT2 LX42. | Stop the engine and allow it to cool; check coolant level and radiator for debris; if recurring, have the cooling system inspected. | |
| Transmission Temp | AMBER | Hydrostatic transmission fluid temperature is high, reducing performance and potentially damaging the transmission on your XT2 LX42. | Reduce mowing speed or stop and let the transmission cool; check fluid level and ensure cooling fan is unobstructed. | |
| Parking Brake | AMBER | The parking brake is engaged; the tractor will not move until it is released. | Disengage the parking brake before attempting to drive. | |
| Low Fuel | AMBER | Fuel level is low; you have approximately 1 gallon remaining in the tank. | Refuel as soon as possible to avoid running out during operation. | |
| High Beam | BLUE | The headlights are on high beam, providing increased forward illumination. | Switch to low beam when approaching others to avoid glare. | |
| PTO Engaged | GREEN | The power take-off (PTO) is engaged, driving the mower deck or attachment. | Disengage the PTO before getting off the tractor or working near the attachment. | |
| Service / Hour Meter | AMBER | Maintenance is due based on engine hours; the indicator reminds you to perform scheduled service on your XT2 LX42. | Refer to the owner's manual for the next service interval and perform the required maintenance. |

Most Important Warning Lights
Engine Overheating
Common causes
- Low coolant level
- Radiator debris or blocked airflow
- Faulty radiator fan or thermostat
What to do
Let the engine cool completely; then check coolant level and add 50/50 mix if low. Clean the radiator fins and engine screens with compressed air. If light reappears, have the cooling system serviced by a Cub Cadet dealer.
Low Engine Oil Pressure
Common causes
- Insufficient oil level
- Oil filter clogged
- Oil pump failure or internal leak
What to do
Stop the engine immediately. Check oil level with the dipstick; add 10W-30 oil if low. If light stays on after filling, do not start the engine again—have it towed to a dealer for diagnosis.
Battery Not Charging
Common causes
- Loose or corroded battery cables
- Broken alternator belt
- Faulty voltage regulator or alternator
What to do
Inspect battery terminals and clean if needed. Check the alternator belt tension and condition; replace if worn. If light persists, test the charging system output and consult a dealer if under 13 volts.
Transmission Overheating
Common causes
- Contaminated or low hydrostatic fluid
- Clogged transmission cooling fan or screen
- Extended heavy load operation
What to do
Stop and allow transmission to cool for 15 minutes. Check fluid level with the dipstick at the rear axle; add Cub Cadet Hydrostatic Fluid to the full mark. Clean the cooling fan and screen of debris. Reduce mowing speed or load.
Check Engine (MIL) Active
Common causes
- Oxygen sensor fault
- Loose fuel cap
- Engine emissions control malfunction
What to do
Ensure the fuel cap is tight. If light stays on, the engine may run in a safe mode; limit to light mowing until a dealer can read the fault code and perform repairs.
Frequently Asked Questions
What should I do if the Master Warning light comes on while mowing?
Stop the mower immediately and turn off the engine. Check the owner's manual for the specific meaning—common causes include low oil pressure or overheating. Do not restart until the issue is resolved.
Can I run a Cub Cadet XT2 LX42 with the Check Engine light on?
Yes, but you should limit operation to light duty and lower RPM until the fault is diagnosed. The light indicates an emissions or engine management issue that may affect performance or fuel economy.
How often should I check the transmission fluid on my XT2 LX42?
Check the transmission fluid level every 25 hours of operation or before each mowing season. Use only Cub Cadet Hydrostatic Fluid and fill to the 'Full' mark on the dipstick.
Why does my battery light come on at idle but go off when revving?
The engine may be idling too low, or the alternator belt might be slipping slightly. Check belt tension and idle speed (should be around 3200-3300 RPM with PTO off). If the light stays on at high RPM, have the charging system tested.
What does the amber Transmission Temp light mean?
It means the hydrostatic transmission fluid is getting hot. Reduce mowing speed and avoid tall grass or heavy loads. If the light turns red, stop the tractor and let it cool for 15 minutes before resuming.
Is it normal for the PTO light to stay on when the mower deck is disengaged?
No, the PTO indicator should only be on when the PTO switch is engaged. If it stays on when disengaged, there may be a faulty switch or wiring issue—have it inspected by a dealer.
