Gehl RT175 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A serious fault has been detected in the RT175 that requires immediate engine shutdown to prevent damage. | Stop the engine safely and consult the RT175 service manual. | |
| Master Caution | AMBER | A non-critical issue or system fault has been detected in the RT175, requiring attention soon. | Check other warning lights and service the RT175 as needed. | |
| Check Engine (MIL) | AMBER | The engine control module (ECM) has detected an emission or performance fault in the RT175's Yanmar engine. | Have the engine diagnosed by a Gehl dealer to avoid reduced power. | |
| Engine Oil Pressure | RED | Engine oil pressure in the RT175 has dropped below safe operating levels, risking engine seizure. | Shut off the engine immediately and check oil level and pressure sensor. | |
| Battery / Charging | RED | The RT175's charging system is not supplying sufficient voltage; the battery may be discharging. | Check alternator belt, connections, and battery condition. | |
| Coolant Temperature | RED | Engine coolant temperature in the RT175 has exceeded safe limits, risking overheating damage. | Stop the engine, let it cool, and inspect the cooling system. | |
| Transmission Temp | AMBER | The hydrostatic transmission fluid in the RT175 is too hot; performance may be reduced. | Reduce load and allow the transmission to cool; check fluid level. | |
| Brake System | RED | A fault in the RT175's brake hydraulic system has been detected, potentially reducing braking performance. | Do not operate; inspect brake fluid and system components. | |
| Parking Brake | AMBER | The parking brake on the RT175 is engaged or not fully released. | Release the parking brake before moving the machine. | |
| Seat Belt | RED | The operator's seat belt on the RT175 is not fastened; the machine may not start or may be in a warning state. | Fasten your seat belt before operating the RT175. | |
| Glow Plug / Preheat | AMBER | The glow plugs in the RT175's diesel engine are preheating for cold start; wait for the light to turn off. | Turn the key to the on position and wait for the light to extinguish before cranking. | |
| DPF / Regeneration | AMBER | The diesel particulate filter (DPF) in the RT175 requires regeneration to clear soot buildup. | Operate at high engine speed to perform active regeneration or take to dealer. | |
| Low Fuel | AMBER | The fuel level in the RT175's tank is low; refuel soon to avoid running out. | Add diesel fuel to the tank. | |
| High Beam | BLUE | The high-beam headlights on the RT175 are activated. | Dim when approaching other vehicles. | |
| Hydraulic System | RED | A serious fault in the RT175's hydraulic system could cause loss of lift or drive functions. | Stop operation and inspect hydraulic fluid and components. | |
| Hydraulic Oil | AMBER | Hydraulic oil temperature or level in the RT175 is abnormal; performance may degrade. | Check hydraulic oil level and temperature; allow cooling if hot. | |
| Air Filter | AMBER | The engine air filter on the RT175 is restricted; clean or replace to maintain performance. | Inspect and replace the air filter if dirty. | |
| Service / Hour Meter | AMBER | The RT175 has reached a scheduled maintenance interval based on engine hours. | Perform the required service as per the operator's manual. | |
| Work Lights | GREEN | The work lights on the RT175 are turned on for improved visibility. | Turn off when not needed to conserve battery. | |
| Beacon / Rotating Light | GREEN | The rotating beacon on the RT175 is active to alert nearby personnel. | Use when operating in areas with pedestrian traffic. |

Most Important Warning Lights
Engine Overheat
Common causes
- Low coolant level
- Radiator blockage
- Faulty cooling fan
What to do
Stop the Gehl RT175 immediately and allow the engine to cool. Check coolant level and radiator fins for debris. If the issue persists, have the cooling system inspected by a Gehl technician.
Hydraulic System Failure
Common causes
- Low hydraulic oil
- Leaking hoses
- Contaminated fluid
What to do
Park the RT175 on level ground, engage the parking brake, and inspect hydraulic fluid level and hoses. Add approved hydraulic oil and repair leaks before resuming operation.
Transmission Overheat
Common causes
- High load operation
- Low transmission fluid
- Clogged cooler
What to do
Reduce load on the RT175 and allow the transmission to cool. Check fluid level and condition; clean the transmission cooler fins if blocked.
Low Engine Oil Pressure
Common causes
- Low oil level
- Oil filter clogged
- Oil pump failure
What to do
Shut down the RT175 engine immediately. Check oil level and add oil if needed. Inspect for leaks and replace oil filter if overdue. If light persists, seek dealer service.
Electrical Charging Fault
Common causes
- Faulty alternator
- Loose battery cables
- Blown fuse
What to do
Check battery connections on the RT175 for tightness and corrosion. Test alternator output and inspect fuses related to charging. Replace damaged components as needed.
Frequently Asked Questions
What does the amber master caution light mean on my Gehl RT175?
It indicates a non-critical fault has been detected. Check the other warning lights on the dash for more details. Common causes include low fuel, high transmission temperature, or a service reminder.
Why won't my RT175 start when the glow plug light is on?
The glow plug light indicates the engine preheat cycle is active. Wait until the light turns off before turning the key to start. If the light stays on, a glow plug or relay may be faulty.
How do I reset the service hour meter light?
After performing the required maintenance on your RT175, the light can be reset by pressing and holding the hour meter reset button (if equipped) or through the diagnostic menu. Refer to your operator's manual for exact steps.
Can I continue operating with the DPF regeneration light on?
The RT175's DPF light means soot load is high. You can continue operating but should maintain high engine RPM to promote passive regeneration. If the light stays on, active regeneration may be needed; consult your dealer.
What should I do if the hydraulic system warning light comes on?
Stop the RT175 immediately and check the hydraulic oil level. Look for visible leaks around hoses and cylinders. If low, add recommended hydraulic fluid. If the light stays on, do not operate until inspected by a technician.
Why does the parking brake light stay on after releasing the brake?
The light may indicate a faulty parking brake switch or that the brake is not fully disengaged. Check the lever and sensor. If the light remains, have the brake system checked by a Gehl dealer.
