The Massey Ferguson MF 245 is a classic utility tractor from the 1970s, equipped with a simple but essential dashboard indicator set. These lights help the operator monitor engine health, hydraulics, and basic systems during field work. Understanding them is key to reliable operation.
Massey Ferguson MF 245 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Stop (Master Warning) | RED | Illuminates when a critical fault occurs, such as low oil pressure or engine overheat, requiring immediate engine shutdown on the MF 245. | Stop the tractor immediately and identify the underlying issue before restarting. | |
| Engine Oil Pressure | RED | Lights when engine oil pressure drops below safe levels, common on the MF 245 if oil level is low or the oil pump fails. | Stop engine, check oil level and top up if low; if persistent, inspect oil pump and lines. | |
| Battery Charge | RED | Glows when the alternator is not charging, often due to a broken belt or faulty regulator on the MF 245's Lucas electrical system. | Check alternator belt tension and connections; if still on, test alternator output. | |
| Coolant Temperature | RED | Activates when engine coolant exceeds safe temperature, a risk during heavy PTO work or if the radiator is clogged on the MF 245. | Reduce load, let engine idle; check coolant level and fan belt; clean radiator fins if needed. | |
| Brake System | RED | Indicates brake fluid low or system pressure loss, which can occur on the MF 245's mechanical/hydraulic brakes if there is a leak. | Check brake fluid reservoir and inspect lines for leaks; do not operate until repaired. | |
| Parking Brake | AMBER | Stays on when the parking brake lever is engaged, reminding the operator to release it before driving the MF 245. | Release the parking brake fully before moving the tractor. | |
| Glow Plug (Preheat) | AMBER | Lights during cold start preheating on diesel MF 245 models; goes out when the cylinders are ready to start. | Wait for the light to turn off before cranking the engine. | |
| Low Fuel | AMBER | Illuminates when the fuel level in the tank is low, typically with 10-15% remaining on the MF 245. | Refuel as soon as possible to avoid running out during operation. | |
| High Beam | BLUE | Blue indicator that lights when the headlights are switched to high beam for better field visibility at night on the MF 245. | Dim to low beam when approaching other vehicles or in dusty conditions. | |
| Work Lights | GREEN | Green light that illuminates when the rear or auxiliary work lamps are activated for implement lighting on the MF 245. | Turn off when not needed to save battery and bulb life. | |
| Hydraulic System | AMBER | Warns of low hydraulic oil level or filter blockage, affecting the MF 245's three-point hitch and remote valves. | Check hydraulic oil level and clean/replace filter; inspect hoses for leaks. | |
| Differential Lock | GREEN | Indicator shows when the rear differential is locked for better traction in slippery conditions on the MF 245. | Disengage on firm ground and when turning to avoid driveline strain. |

Most Important Warning Lights
Engine Overheat
Common causes
- Low coolant level
- Clogged radiator
- Broken fan belt
What to do
Stop the MF 245 immediately, let engine cool, then check coolant and belt. Clean radiator fins with compressed air. If persistent, check water pump.
Low Oil Pressure
Common causes
- Low oil level
- Oil pump failure
- Worn bearings
What to do
Stop engine right away. Check dipstick and add oil if low. If light stays on, do not run engine – inspect oil pump and pressure relief valve on the MF 245 engine.
Brake Failure
Common causes
- Brake fluid leak
- Worn brake linings
- Air in system
What to do
Do not move the tractor. Check brake fluid reservoir; if empty, inspect lines for leaks. Bleed brakes if air is present. Replace worn shoes as needed on the MF 245.
Alternator Not Charging
Common causes
- Broken fan belt
- Faulty alternator
- Loose wiring
What to do
Check belt tension and replace if frayed. Test alternator output with a voltmeter at the battery; if less than 13.5V, repair or replace alternator (common Lucas unit on MF 245).
Hydraulic System Malfunction
Common causes
- Low hydraulic oil
- Clogged filter
- Leaking hose
What to do
Stop implement use. Check oil level at dipstick, top up with correct fluid. Replace hydraulic filter if dirty. Inspect hoses for leaks and tighten fittings on the MF 245.
Frequently Asked Questions
Why does my MF 245 battery light stay on after starting?
It usually means the alternator isn’t charging. Check the fan belt tension and wiring connections. If okay, the alternator or voltage regulator may need replacement.
What does the amber glow plug light mean on my MF 245?
That light indicates the preheat system is active for cold starting. Wait until it goes out before turning the key to start – typically 10–15 seconds in cold weather.
How do I know if my MF 245 is overheating?
The red coolant temperature light will come on, and the gauge may be in the red zone. You’ll also see steam or hear coolant boiling. Stop the tractor immediately and let it cool.
The brake warning light is on but fluid level is fine – what now?
There could be air in the brake lines or a faulty pressure switch. Bleed the brakes according to the MF 245 manual. If the light stays on, replace the switch.
My MF 245’s hydraulic light comes on when using the loader. Is that serious?
It indicates low oil level or a clogged filter. Check the hydraulic dipstick with the loader lowered. Add oil if low, and change the filter. Avoid heavy use until fixed.
What should I do if the oil pressure light flickers at idle?
That could be normal on a warm engine, but if it stays on, stop immediately. Check oil level and pressure switch. If the pressure is truly low, inspect the oil pump or relief valve.
