The Massey Ferguson MF 175 is a classic utility tractor renowned for its robust Perkins diesel engine and simple, reliable design. The instrument cluster consists of basic warning lights to monitor critical systems, using a standard color code for quick identification.
Massey Ferguson MF 175 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Engine Oil Pressure | RED | This red light illuminates when engine oil pressure drops below safe operating level, often due to low oil or a faulty pump on your MF 175. | Stop the engine immediately and check oil level; if full, do not restart and consult a mechanic. | |
| Battery / Charging | RED | Glowing red when the alternator is not charging or the battery voltage is too low, common on MF 175 with worn belts or aging alternator. | Check alternator belt tension and battery connections; if persistent, replace the alternator. | |
| Coolant Temperature | RED | This red warning signals that the engine coolant temperature is too high, often from a clogged radiator or low coolant on the MF 175. | Pull over, idle engine to cool, then check coolant level and radiator for debris. | |
| Glow Plug / Preheat | AMBER | Amber light comes on when glow plugs are activated for cold starting; typical on Perkins diesel engines in MF 175. | Wait until the light goes out before turning the starter; if it stays on, glow plugs may need replacement. | |
| Low Fuel | AMBER | Amber indicator warns that the fuel level is low; on MF 175, it's essential to avoid air ingress in the fuel system. | Refuel as soon as possible; do not run the tank dry to avoid bleeding the system. | |
| High Beam | BLUE | Blue light shows the high-beam headlights are on, useful for field work at night on the MF 175. | No action required unless blinding oncoming traffic; dip to low beam when necessary. | |
| Parking Brake | RED | Red light indicates parking brake is engaged; on MF 175, it's a mechanical lever that must be released before driving. | Release the parking brake fully before moving the tractor. | |
| Hydraulic System | AMBER | Amber light signals a problem with the hydraulic system, such as low fluid or a clogged filter on the MF 175. | Check hydraulic fluid level and condition; inspect filter if light persists. | |
| Differential Lock | AMBER | Amber light indicates the differential lock is engaged, providing extra traction on the MF 175 for slippery conditions. | Disengage when turning on hard surfaces to prevent driveline binding. | |
| PTO Engaged | GREEN | Green light shows the power take-off is engaged, driving implements like mowers or balers on the MF 175. | Disengage PTO before servicing or when not in use. |

Most Important Warning Lights
Low Engine Oil Pressure
Common causes
- Low oil level
- Oil pump failure
- Worn engine bearings
What to do
Stop the engine immediately on your MF 175. Check oil level and top up with 15W-40 diesel oil. If light stays off after restart, monitor; if it returns, inspect oil pump or seek professional service.
Engine Overheating
Common causes
- Low coolant
- Clogged radiator fins
- Faulty thermostat
What to do
Let the MF 175 idle to cool, then carefully remove radiator cap (when cool) and add 50/50 coolant mix. Clean radiator exterior with compressed air; if overheating recurs, replace thermostat.
Charging System Failure
Common causes
- Loose alternator belt
- Faulty alternator
- Corroded battery terminals
What to do
On your MF 175, tighten or replace the alternator belt if loose. Clean battery terminals with a wire brush. If the light stays on, alternator may need replacement.
Hydraulic System Leak
Common causes
- Damaged hydraulic hose
- Loose fitting
- Worn pump seal
What to do
Inspect hydraulic hoses and fittings on the MF 175 for leaks. Tighten connections or replace damaged hoses. Check fluid level in the hydraulic reservoir; use UTF (Universal Tractor Fluid).
Fuel System Air Lock
Common causes
- Running out of fuel
- Loose fuel line
- Clogged fuel filter
What to do
On the MF 175, bleed air from the fuel system by loosening the injector line nuts and cranking until fuel spurts. Replace the fuel filter if clogged.
Frequently Asked Questions
What does the red oil light mean on my MF 175?
The red oil light indicates low engine oil pressure. Stop the tractor immediately to prevent engine damage, check oil level, and add oil if needed. If the light remains on, consult a mechanic.
How long should the glow plug light stay on?
On a cold MF 175, the amber glow plug light typically stays on for 5-15 seconds depending on engine temperature. Wait until it goes out before starting. If it stays on longer, glow plugs may need testing.
Why is my battery light on while running?
The battery light on while the MF 175 is running means the alternator is not charging. Check the belt tension and battery connections. If okay, the alternator may be faulty.
Can I drive with the parking brake light on?
No, the red parking brake light means the brake is engaged. Driving with it on can overheat brakes and cause damage. Always release the parking brake fully before moving the MF 175.
What causes the hydraulic light to come on?
The amber hydraulic light on the MF 175 warns of low hydraulic fluid, a clogged filter, or a leak. Check fluid level and look for leaks under the tractor. Top up with UTF as needed.
How do I know if my MF 175 is overheating?
The red coolant temperature light will illuminate. You may also see steam from the radiator. Stop the tractor, let it idle to cool, then check coolant level after the engine is cool enough to touch the radiator cap.
