Massey Ferguson MF 250 Warning Light Symbols

SymbolNameColorWhat it meansWhat to do
Master Warning (Stop)REDThis red stoplight illuminates when a major fault, such as low oil pressure or overheating, is detected in the MF 250's engine or powertrain.Stop the tractor immediately, shut off the engine, and inspect the oil level, coolant level, and belts.
Master CautionAMBERThis amber caution lamp alerts you to a non-critical but important system issue, such as a partially clogged air filter or a hydraulic fluid temperature rise on your MF 250.Check the operator's manual for the specific fault; if safe, continue operation at reduced load until maintenance is possible.
Engine Oil PressureREDWhen lit, this red lamp indicates that the MF 250's engine oil pressure has dropped below safe operating range, risking severe engine damage.Shut off the engine immediately, check the oil level and pressure sending unit, and do not restart until the issue is resolved.
Battery / ChargingREDThis red light comes on when the alternator is not charging the battery on your MF 250, or the charging voltage is too low.Stop the engine, check the alternator belt tension and wiring connections; start the tractor only after the charging system is repaired.
Coolant TemperatureREDIlluminates red when the engine coolant temperature on your MF 250 exceeds the normal range, risking overheating and engine damage.Reduce engine load immediately; if light stays on, shut down, allow the engine to cool, and check the coolant level and radiator fins.
Glow Plug / PreheatAMBERThis amber light stays on while the glow plugs are warming the combustion chambers of your MF 250's diesel engine for cold starts.Wait for the light to go out before turning the key to start; do not crank the engine while it is illuminated.
PParking BrakeREDThis red indicator shows that the parking brake on your MF 250 is engaged; it may also flash if the brake is partially applied while moving.Fully release the parking brake before driving; if the light remains on, check the brake linkage or switch adjustment.
Low FuelAMBERLights up amber when the fuel level in your MF 250's tank drops to about 1/4 full or less, reminding you to refill.Refuel as soon as possible to avoid running out of fuel and drawing air into the injection system.
High BeamBLUEThis blue indicator confirms that the headlights are set to high beam on your MF 250 for enhanced visibility in open fields.Switch to low beam when approaching other vehicles or when working near buildings to avoid glare.
Hydraulic SystemAMBERAn amber light indicates that the hydraulic system temperature or pressure is outside the normal operating range for your MF 250's lift and implement controls.Reduce hydraulic load, check fluid level and cooler; if light persists, inspect for leaks or a faulty relief valve.
PTOPTO EngagedGREENThis green light shows that the power take-off is engaged on your MF 250, delivering power to attached implements.Ensure the PTO is disengaged before starting the engine or leaving the seat, and never operate without the guard in place.
Differential LockAMBERIlluminates amber when the differential lock is engaged on your MF 250, locking both rear wheels together for better traction in slippery conditions.Disengage the differential lock when turning on hard surfaces to prevent driveline damage; use only when needed.
Work LightsGREENThis green indicator shows that the rear or front work lights are turned on for nighttime or low-light operations on your MF 250.Turn off work lights when not needed to conserve battery power and avoid blinding other operators.
Water in FuelAMBERAn amber light alerts you that water has accumulated in the fuel filter water separator on your MF 250, which could cause injection system damage.Drain the water separator bowl as described in the operator's manual; replace the filter if necessary.

Most Important Warning Lights

Engine Overheating

Common causes

  • Low coolant level
  • Blocked radiator fins
  • Faulty thermostat or water pump

What to do

On the MF 250, stop the engine immediately, let it cool, then check the coolant reservoir and radiator for debris. Clean the radiator fins with compressed air and replace the thermostat if the engine still runs hot.

Low Oil Pressure

Common causes

  • Low engine oil level
  • Worn oil pump
  • Clogged oil filter or passages

What to do

Shut off the MF 250 engine and check the oil dipstick. If low, add the recommended viscosity oil. If the light persists, inspect the oil pump drive and replace the oil filter; do not run the engine until pressure is restored.

Charging System Failure

Common causes

  • Loose or broken alternator belt
  • Faulty alternator
  • Battery cable corrosion

What to do

Turn off all electrical loads and check the alternator belt tension on your MF 250. Tighten or replace the belt if needed. Clean battery terminals and check alternator output with a voltmeter; replace the alternator if its output is below 13.5 volts.

Hydraulic System Overheating

Common causes

  • Low hydraulic fluid level
  • Continuous high load without rest
  • Clogged hydraulic oil cooler

What to do

Reduce the hydraulic load on the MF 250, let the system cool, then check the hydraulic fluid level and top up with the correct grade. Clean the oil cooler fins and ensure the fan belt is tight; avoid excessive continuous operation at high pressure.

Frequently Asked Questions

What should I do if the red stop light comes on while plowing with my MF 250?

Immediately disengage the PTO, drop the implement, and idle the engine. Shut down after a brief cooldown period. Check the oil pressure, coolant temperature, and charging system; refer to the critical list above for common fixes.

How long should I wait for the glow plug light on my MF 250 to go out before starting?

Typically 5 to 15 seconds depending on ambient temperature. Wait until the amber glow plug indicator turns off completely; do not crank the engine while it is lit to avoid battery drain and starter wear.

Why does the PTO light on my MF 250 stay on even when the lever is off?

This may indicate a stuck or misadjusted PTO switch. Check the mechanical linkage under the seat and ensure the lever fully returns to neutral. If the light persists, the switch may need replacement to prevent accidental engagement.

Can I continue working if the amber hydraulic warning light flickers occasionally on my MF 250?

Occasional flickering may be due to a temporary overheat or low fluid sloshing. However, if the light stays on or flashes frequently, reduce hydraulic load and check fluid level. Continued operation can damage the hydraulic pump or seals.

How often should I drain the water separator on my MF 250 to prevent the water-in-fuel light?

Drain the separator every 50 hours or at each fuel fill-up, especially in humid conditions. If the light comes on, drain immediately; failure to do so can allow water to reach injectors, causing poor performance and corrosion.

My MF 250's high beam indicator is dim. Is that normal?

A dim high beam indicator typically means a poor ground or low voltage at the bulb. Check the instrument cluster connections and the headlight switch; if the actual high beams work normally, the indicator bulb may need replacement.
