Kubota BX23S Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning | RED | A general stop signal triggered by a serious system fault on your BX23S, such as engine shutdown or critical hydraulic failure. | Stop the engine immediately and refer to the operator's manual for the specific fault code. | |
| Engine Oil Pressure | RED | Indicates low engine oil pressure, which can cause immediate engine damage if ignored. | Stop the engine, check oil level, and inspect for leaks. | |
| Battery/Charging | RED | The alternator is not charging the battery or there is a charging system fault. | Stop the engine and check battery connections and alternator belt tension. | |
| Coolant Temperature | RED | Engine coolant temperature is too high, risking overheating and engine damage. | Stop the engine, allow it to cool, and check coolant level and radiator screen for debris. | |
| Parking Brake | AMBER | Reminds you that the parking brake is engaged, which must be disengaged before driving. | Release the parking brake before moving the tractor. | |
| Seat Belt | AMBER | Indicates the operator's seat belt is not fastened. | Fasten your seat belt for safety. | |
| Glow Plug/Preheat | AMBER | Glow plugs are preheating the engine for cold starts; wait until it turns off before cranking. | Wait for the light to go out, then start the engine. | |
| Low Fuel | AMBER | The fuel level is low; refuel soon to avoid running out during work. | Add diesel fuel to the tank. | |
| High Beam | BLUE | Indicates the high beam headlights are on. | Dim your lights when approaching other vehicles. | |
| Work Lights | GREEN | The work lights (rear or front) are turned on. | No action needed; use as needed. | |
| Differential Lock | AMBER | The differential lock is engaged, providing equal traction to both rear wheels. | Disengage when turning on hard surfaces to avoid driveline binding. | |
| PTO Engaged | AMBER | The power take-off (PTO) is engaged and rotating. | Ensure PTO-driven attachments are clear before starting the tractor. | |
| Hydraulic System | RED | The hydraulic system has low pressure or a fault, affecting loader and three-point hitch operation. | Stop the engine and check hydraulic fluid level and filter condition. |

Most Important Warning Lights
Engine Overheating
Common causes
- Low coolant level
- Clogged radiator screen
- Faulty thermostat
What to do
Stop the engine, let it cool, clean the radiator screen, and check coolant level in the recovery tank. If recurring, inspect the thermostat or water pump.
Low Oil Pressure
Common causes
- Low oil level
- Oil filter clogged
- Oil pump failure
What to do
Stop the engine immediately. Check oil level with the dipstick; top up if low. If level is correct, have the oil pressure switch or pump checked by a dealer.
Charging System Failure
Common causes
- Loose or corroded battery terminals
- Alternator belt broken
- Alternator failure
What to do
Stop the engine. Tighten battery connections; if belt is loose, adjust or replace. If the light remains after restart, the alternator may need replacement.
Hydraulic System Warning
Common causes
- Low hydraulic fluid
- Hydraulic filter clogged
- Internal hydraulic pump wear
What to do
Stop the engine. Check hydraulic fluid level at the reservoir; add if low. Replace the hydraulic filter as per maintenance schedule. If problem persists, consult a technician.
Master Warning Light On
Common causes
- Multiple system faults
- Engine shutdown condition
- Critical hydraulic or electrical fault
What to do
Stop the engine immediately. Note any other warning lights and check the owner's manual for fault codes. Contact your Kubota dealer for diagnosis.
Frequently Asked Questions
Why does my glow plug light stay on for a long time?
The BX23S glow plug system may take longer in cold weather; if it stays on for more than 10 seconds after ignition, your glow plugs or controller may be faulty.
What does the PTO light mean?
The amber PTO light indicates the rear PTO lever is engaged; always disengage when not using attachments to avoid accidental operation.
Is it normal for the battery light to flash briefly at startup?
Yes, a brief flash is normal as the alternator self-checks; if it stays on, the charging system needs inspection.
Can I operate the tractor with the hydraulic warning light on?
No, continued operation may damage the hydraulic pump or implements; stop and check fluid level or filter.
Why does my differential lock light stay on?
The diff lock may be stuck engaged; try disengaging while moving slowly and gently. If it stays on, inspect the linkage for binding.
How do I reset the master warning light?
The master warning light is tied to a fault code; you must resolve the underlying issue and restart the engine. If it persists, have the system scanned by a dealer.
