Master Warning (Stop)REDA serious fault requires immediate engine shutdown on your 6130R.Stop the tractor safely, turn off engine, and consult the operator’s manual or dealer.
Master CautionAMBERA non-critical issue needs attention; the 6130R's electronic system has detected a fault that should be checked soon.Review the display messages and service the tractor at your earliest convenience.
Check Engine (MIL)AMBERThe engine control unit on your 6130R has detected a fault – could be emissions, fuel, or sensor related.Reduce load and have the engine diagnosed by a John Deere technician.
Engine Oil PressureREDOil pressure is below safe operating level for the 6130R engine; continued operation can cause severe damage.Shut off engine immediately and check oil level and pressure system.
Battery / ChargingREDThe alternator is not charging properly or battery voltage is low on your 6130R.Check alternator belt, connections, and battery condition; service if needed.
Coolant TemperatureREDEngine coolant temperature is above safe limit – the 6130R's cooling system may be blocked or low on coolant.Stop engine, let cool, check coolant level and radiator fins.
ATTransmission TempAMBERTransmission oil temperature is elevated; on the 6130R this often occurs during heavy PTO work or high loads.Reduce load or shift to a lower gear; allow transmission to cool.
Brake SystemREDA fault in the 6130R's service brakes – could be low brake fluid or worn pads.Check brake fluid reservoir; if low, top off and inspect for leaks.
PParking BrakeAMBERThe parking brake on your 6130R is engaged; release before moving.Release the parking brake lever or button before driving.
Glow Plug / PreheatAMBERThe preheat system is active on the 6130R; wait for the light to go out before starting in cold conditions.Turn ignition to position, wait for glow plug light to extinguish, then start.
DPF / RegenerationAMBERThe diesel particulate filter on your 6130R is performing active regeneration to burn off soot.Keep engine running and avoid idling; do not interrupt the process.
DEF / AdBlueAMBERDEF level is low or system fault; on the 6130R this will eventually limit engine power.Refill DEF tank using approved fluid; if light persists, service the SCR system.
Water in FuelAMBERWater has accumulated in the fuel filter/water separator of the 6130R.Drain the water separator bowl or replace the fuel filter.
Low FuelAMBERFuel level is low in the 6130R tank; refuel soon to avoid air in the system.Add diesel fuel; ensure high quality to prevent injector issues.
High BeamBLUEHigh beam headlights are active on your 6130R for field work.Dim when approaching other vehicles on road.
Hydraulic SystemAMBERA hydraulic system fault has been detected in the 6130R – possibly low oil or a filter issue.Check hydraulic oil level and condition; inspect for leaks.
Fasten Seat BeltREDSeat belt is not fastened; the 6130R requires it for operator safety.Fasten your seat belt before operating.
Reduced Power (Limp Mode)AMBEREngine power is reduced to protect the 6130R’s drivetrain – likely due to high temp or emissions issue.Stop and diagnose the underlying cause; possible regen or sensor fault.
Hydraulic OilAMBERHydraulic oil temperature is high on your 6130R – check oil level and cooler function.Reduce hydraulic load and allow oil to cool; check level.
Engine Oil TemperatureAMBEREngine oil temperature is above normal on the 6130R – could be from heavy load or low oil.Reduce engine load and check oil level and cooling.
Air FilterAMBERAir filter restriction indicator on the 6130R shows filter needs cleaning or replacement.Replace or clean the air filter element.
Fuel Filter / Water SeparatorAMBERFuel filter is clogged or water separator needs draining on the 6130R.Replace fuel filter and drain water from separator.
Service / Hour MeterAMBERService interval is approaching or due based on engine hours on your 6130R.Perform scheduled maintenance as per operator’s manual.
Work LightsGREENWork lights on the 6130R are turned on for nighttime operation.Turn off when not needed to save battery.
Beacon / Rotating LightGREENBeacon is active on the 6130R to warn others of slow-moving vehicle.Ensure beacon is operational when traveling on roads.
Differential LockGREENDifferential lock is engaged on the 6130R for better traction in slippery conditions.Disengage when turning on hard surfaces to prevent driveline damage.
PTOPTO EngagedGREENThe rear PTO on the 6130R is engaged; be cautious of rotating shafts.Disengage PTO when not in use and always use shielding.
TrailerGREENA trailer is connected and recognized by the 6130R’s electrical system.Check trailer lights and brakes before towing.

Most Important Warning Lights

Engine Overheating

Common causes

  • Low coolant level
  • Radiator blockage
  • Broken fan belt

What to do

Stop and shut down the 6130R engine immediately. Once cooled, check coolant level, clean radiator fins, and inspect belt tension. If persistent, have the cooling system serviced.

Transmission Overheat

Common causes

  • Excessive PTO load
  • Low transmission oil
  • Clogged cooler

What to do

Reduce load or shift to a lower gear on the 6130R to allow cooling. Check transmission oil level and condition; clean the cooler fins. If it continues, consult a dealer.

DEF System Fault

Common causes

  • Low DEF fluid
  • DEF pump failure
  • NOx sensor malfunction

What to do

Refill the DEF tank on your 6130R with approved fluid. If warning persists, the dealer may need to diagnose the SCR system and replace faulty components.

DPF Clogged

Common causes

  • Frequent short trips
  • Excessive idling
  • Low exhaust temperature

What to do

Perform a stationary regeneration on the 6130R by engaging the regen switch (if equipped) or take the tractor for a long highway run at high load. If light remains, service is required.

Battery/Charging Failure

Common causes

  • Alternator belt slip
  • Worn alternator
  • Corroded terminals

What to do

Check and tighten alternator belt on the 6130R, clean battery terminals, and measure charging voltage. Replace alternator if output is low.

Frequently Asked Questions

Why does my 6130R show a red Master Warning light?

The red Master Warning indicates a critical fault that requires immediate engine shutdown. Check the display for a specific message (e.g., low oil pressure, high coolant temp) and follow the appropriate action outlined in the manual.

How do I perform a DPF regeneration on the 6130R?

When the DPF light is amber, the tractor may be performing automatic regeneration. If it requests manual regen, park safely, engage the regen switch (if equipped), and let the engine run at high idle until the light goes out – typically 20-30 minutes.

What does the amber Hydraulic System light mean?

On the 6130R, this light signals low hydraulic oil level, a clogged filter, or high oil temperature. Check the sight glass and top off with Hy-Gard oil; also inspect the filter for blockage.

The Check Engine light is on – can I continue working?

You may continue if performance is okay, but reduce load and have the 6130R diagnosed soon. The light could indicate minor sensor issues or a developing problem that may lead to reduced power or shutdown.

Why does my 6130R have a amber Glow Plug light when it's warm?

The glow plug light may stay on briefly for post-heating to reduce emissions. If it remains on constantly, suspect a glow plug relay or controller fault – have it checked by a dealer.

How do I reset the service hour meter on the 6130R?

The hour meter cannot be reset by the operator; it is a maintenance reminder. After performing the required service, the dealer can reset it using Service Advisor.
