Deutz-Fahr Agrotron 6150 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A serious fault has been detected that demands an immediate engine stop to prevent damage on your Agrotron 6150. | Stop the tractor safely and consult the display for the specific fault code. | |
| Master Caution | AMBER | A non-critical system anomaly has been registered; check the center display for additional warnings on your 6150. | Review warning messages and address the underlying issue soon. | |
| Check Engine | AMBER | The engine control unit has detected an emission or performance fault in the Deutz TCD 6.1 L6 engine. | Have the fault codes read by a dealer; avoid heavy load if flashing. | |
| Engine Oil Pressure | RED | Oil pressure has dropped below safe levels in the 6150’s engine, risking severe wear. | Stop immediately, check oil level and for leaks; do not restart. | |
| Battery / Charging | RED | The alternator is not charging the battery properly on your Agrotron 6150. | Check connections and belt tension; if light stays, replace alternator. | |
| Coolant Temperature | RED | Engine coolant temperature has exceeded the safe threshold of the 6150’s cooling system. | Reduce load and idle to cool; check coolant level and fan operation. | |
| Transmission Temp | RED | The ZF transmission oil is overheating, which can damage the gearbox on your 6150. | Stop and let transmission cool; check oil level and radiator cleanliness. | |
| Brake System | RED | A fault in the hydraulic brake circuit has been detected on the Agrotron 6150. | Stop and check brake fluid level; do not operate until repaired. | |
| Parking Brake | GREEN | The parking brake is engaged on your 6150. | Release the parking brake before moving. | |
| Glow Plug / Preheat | AMBER | The preheat system is active for cold starting the Deutz engine in your Agrotron 6150. | Wait for the light to go out before cranking (typically below 0°C). | |
| DPF / Regeneration | AMBER | The diesel particulate filter is loading and needs regeneration to clear soot from the exhaust system. | Drive at medium load (PTO > 1500 rpm) to initiate active regen; if flashing, see dealer. | |
| DEF / AdBlue | AMBER | AdBlue level is low or quality is poor, affecting SCR emission control on your 6150. | Refill with genuine Deutz-Fahr DEF; if light persists, have system checked. | |
| Water in Fuel | AMBER | Water has accumulated in the fuel pre-filter water separator on your Agrotron 6150. | Drain the water separator immediately; replace filter if contaminated. | |
| Low Fuel | AMBER | The fuel level in the tank is low; the 6150 has a 300-liter capacity. | Refuel as soon as possible to avoid air in the system. | |
| High Beam | BLUE | The high-beam headlights are activated for forward illumination. | Dim when approaching other vehicles. | |
| Hydraulic System | RED | A hydraulic system fault (e.g., low oil or filter restriction) has been detected on the 6150. | Stop and check hydraulic oil level and filter; if light persists, seek service. | |
| Fasten Seat Belt | RED | The driver’s seat belt is not fastened; on Agrotron 6150 this light may flash with a chime. | Fasten your seat belt for safety and to silence the alarm. | |
| Reduced Power (Limp Mode) | AMBER | Engine power is automatically reduced to protect the transmission or engine on your 6150. | Slow down and get to a service area; check for overheating or transmission codes. | |
| PTO Engaged | GREEN | The rear PTO is engaged and turning; the 6150 has a 540/1000 rpm two-stage system. | Disengage before working near the shaft. | |
| Differential Lock | GREEN | The rear differential lock is engaged for improved traction. | Disengage when turning on hard surfaces to avoid driveline stress. | |
| Air Filter | AMBER | The engine air filter restriction indicator shows the filter is partially clogged on your 6150. | Replace the air filter element soon to maintain engine performance. | |
| High Exhaust Temp (HEST) | AMBER | The exhaust temperature is high during DPF regeneration on your Agrotron 6150. | Keep the tractor away from flammable materials; do not stop the engine during regen. |

Most Important Warning Lights
Engine Overheating
Common causes
- Low coolant level
- Radiator blockage (chaff, dust)
- Faulty thermostatic fan clutch
What to do
Stop immediately, let engine idle with park brake on. Check coolant reservoir and clean the radiator grille using compressed air. If light persists, inspect the fan clutch (common on 6150).
Transmission Overheating
Common causes
- Low transmission oil level
- Clogged oil cooler fins
- Excessive clutch slippage in low range
What to do
Park and let transmission cool. Check oil level at the dipstick (located left side of transmission). Clean the transmission oil cooler with a pressure washer. If light remains, have the hydraulic system tested.
DPF Regeneration Failure
Common causes
- Frequent light-load operation below 1500 rpm
- Faulty exhaust temperature sensor
- Fuel quality issues (high sulfur)
What to do
Manually initiate a stationary regeneration via the dash menu (press Info button for 3 seconds). If light flashes, take to a dealer for forced regen; avoid idling for long periods on the 6150.
Low Engine Oil Pressure
Common causes
- Oil level too low
- Oil pump failure
- Clogged oil filter or relief valve stuck
What to do
Stop engine immediately. Check oil level with dipstick (right side of engine). If level OK, do not restart; tow to dealer. On the 6150, a sudden drop may indicate a failed oil pump gear.
Frequently Asked Questions
Why does the DPF light flash amber while I'm light-loading my Agrotron 6150?
The DPF light flashes when soot load is high and passive regen cannot occur due to low exhaust temperature. Increase engine load (e.g., PTO work at 1800 rpm) for 20 minutes to trigger active regeneration.
My 6150 shows a red master warning and the check engine light after a cold start. What should I do?
Check the instrument display for a specific code (e.g., 'Engine Oil Pressure' or 'Coolant Temp'). If no other light is present, it may be a false code from the ECU. Allow the engine to warm up for 2 minutes; if light persists, read codes with a diagnostic tool (common on 6150 for glow plug faults).
How do I reset the service interval light on the Deutz-Fahr Agrotron 6150?
Switch ignition off, press and hold the 'Info' button on the right-hand steering column, then turn ignition on. Keep holding until the service symbol clears (about 5 seconds). Release and confirm with the 'Enter' key.
What does the green diff lock light mean when I'm driving in the field?
The diff lock is engaged, which is normal when pulling a heavy load in soft soil. It will automatically disengage when turning if the tractor is equipped with the auto diff lock option. If it stays on while steering, check the switch or solenoid on the rear axle.
My DEF level light came on even though I refilled it yesterday. Is it a sensor issue?
On the 6150, the DEF tank has a float sensor that can stick if urea crystals form. Drain the tank and refill with fresh DEF. If the light stays, have the sensor replaced under warranty. Also, ensure you use only Deutz-specified AdBlue to avoid system damage.
The PTO warning light stays on after disengaging the PTO. Is this normal?
No, the light should go out. This usually indicates a faulty PTO engagement switch on the left rear fender. Try toggling the switch a few times; if light remains, the switch or control unit needs replacement. Do not operate the tractor as the PTO may re-engage unexpectedly.
