LS Tractor MT125 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A serious fault has been detected that demands immediate engine shutdown on your MT125 to prevent damage. | Stop the tractor safely, turn off the engine, and consult the operator's manual. | |
| Master Caution | AMBER | A non-critical system requires attention on your MT125; check other warning lights for details. | Identify and address the additional illuminated light. | |
| Check Engine (MIL) | AMBER | The engine control system has detected a fault that could affect emissions or performance on your MT125. | Have the tractor diagnosed by a dealer; continued use may reduce power. | |
| Engine Oil Pressure | RED | Engine oil pressure is too low, risking severe internal damage on your MT125. | Immediately stop the engine and check oil level and pressure. | |
| Battery / Charging | RED | The charging system is not maintaining battery voltage on your MT125, which may lead to a stall. | Check alternator belt and connections; seek service if light stays on. | |
| Coolant Temperature | RED | Engine coolant is overheating on your MT125, which can cause major engine damage. | Stop the engine, let it cool, and check coolant level and fan operation. | |
| Parking Brake | RED | The parking brake is engaged on your MT125; this light should be off when driving. | Release the parking brake before moving the tractor. | |
| Glow Plug / Preheat | AMBER | The glow plugs are preheating the engine for cold starts on your MT125; wait for it to turn off before cranking. | Turn the key to the preheat position and wait until the light goes out. | |
| Low Fuel | AMBER | Fuel level is low on your MT125; you may run out soon if not refilled. | Refuel with clean diesel to prevent air in the system. | |
| High Beam | BLUE | The high-beam headlights are activated on your MT125 for improved visibility. | Switch to low beam when approaching other vehicles. | |
| Cold Coolant | BLUE | Engine coolant is below normal operating temperature on your MT125; allow the engine to warm up. | Run the engine at low speed until the light goes off. | |
| Hydraulic Oil | RED | Hydraulic oil temperature is too high or pressure is low on your MT125, risking system damage. | Reduce load and allow the hydraulics to cool; check fluid level. | |
| Fuel Filter / Water Separator | AMBER | Water has been detected in the fuel or the filter needs service on your MT125. | Drain the water separator or replace the fuel filter. | |
| Service / Hour Meter | AMBER | A scheduled maintenance interval has been reached on your MT125; e.g., engine oil or filter change due. | Perform the required service and reset the light if applicable. | |
| Work Lights | GREEN | The rear or front work lights are turned on for your MT125. | Turn off when not needed to conserve battery. | |
| Differential Lock | GREEN | The differential lock is engaged on your MT125 for increased traction. | Disengage when turning on hard surfaces. | |

Most Important Warning Lights
Engine Overheating
Common causes
- Low coolant level
- Clogged radiator fins
- Faulty thermostat
What to do
On the MT125, stop the engine immediately and let it cool. Check the radiator and coolant reservoir; clean debris from the radiator screen with compressed air or water.
Low Oil Pressure
Common causes
- Low engine oil level
- Oil filter clogged
- Oil pump failure
What to do
Stop the MT125 engine right away. Check the dipstick and top off with the recommended 10W-30 diesel oil. If light persists, inspect the oil filter and pump.
Charging System Failure
Common causes
- Loose or broken alternator belt
- Faulty alternator
- Battery terminal corrosion
What to do
Check the alternator belt tension on your MT125; tighten or replace if worn. Clean battery terminals and ensure connections are tight. Test the alternator output.
Hydraulic Oil Overheat
Common causes
- Low hydraulic oil level
- Excessive load on hydraulics
- Blocked hydraulic oil cooler
What to do
Reduce the load on your MT125's hydraulics and operate at lower RPM. Check the hydraulic oil level and add LS tractor hydraulic fluid. Clean the cooler fins.
Water in Fuel
Common causes
- Contaminated diesel fuel
- Condensation in fuel tank
- Faulty fuel cap seal
What to do
Drain the water separator bowl located on the fuel filter housing of your MT125. Replace the fuel filter if contaminated. Fill with clean diesel from a trusted source.
Frequently Asked Questions
What does the red stop light mean on my MT125?
The red master warning light indicates a critical fault; you must stop the tractor and shut off the engine immediately to prevent damage.
Why is the glow plug light flashing on my MT125?
A flashing glow plug light may indicate a fault in the preheat system; have the glow plugs and relay checked by a dealer.
How do I reset the service interval light on the MT125?
On the MT125, after completing the service, turn the key to the 'ON' position without starting, then press and hold the hazard button for 5 seconds until the light goes out.
Can I drive with the amber check engine light on?
Yes, but you may experience reduced power; schedule a diagnostic check soon to avoid potential engine damage on your MT125.
What should I do if the hydraulic oil light comes on?
Immediately reduce the load on the hydraulics; if the light persists, stop the tractor and check the hydraulic fluid level. Allow the system to cool before resuming work.
How often should I service the fuel filter on my MT125?
Every 200 hours or annually, whichever comes first; drain the water separator more frequently if you suspect contaminated fuel.
