The John Deere Compact 1025R features a straightforward instrument cluster with warning lights that alert you to machine status. Understanding these indicators is key to safe operation and preventing costly repairs. This guide covers every genuine warning light found on the 1025R.
John Deere Compact 1025R Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | This red stop symbol indicates a critical fault—such as low oil pressure or overheating—and requires you to shut down the engine immediately on your 1025R. | Stop the tractor safely, turn off the engine, and consult the operator's manual for the specific fault. | |
| Master Caution | AMBER | An amber caution light on your 1025R means a non-critical system needs attention, like a transmission temperature warning or a service reminder. | Check the LCD display or instrument panel for the specific caution message and address it before continuing heavy work. | |
| Check Engine (MIL) | AMBER | This amber engine icon signals an emissions or engine control issue specific to the 1025R's Yanmar diesel engine. | Schedule a diagnostic check with your John Deere dealer; you may continue limited operation if no performance loss is noticed. | |
| Engine Oil Pressure | RED | A red oil can icon on the 1025R indicates low engine oil pressure, which can cause severe engine damage if ignored. | Immediately stop the engine, check the oil level and add oil if low; if the light remains, call for service. | |
| Battery / Charging | RED | This red battery symbol warns that the 1025R's charging system is not working, possibly due to a failing alternator or loose belt. | Check battery connections and alternator belt tension; if the light stays on, have the charging system tested. | |
| Coolant Temperature | RED | A red thermometer with waves indicates the 1025R's engine coolant is overheating, risking engine seizure. | Pull over immediately, let the engine cool, then check coolant level and radiator fins for debris. | |
| Transmission Temp | AMBER | An amber transmission temperature light on the 1025R warns that the hydrostatic transmission fluid is too hot from heavy use. | Reduce load and operate at lower speed to allow cooling; if it persists, check transmission fluid level. | |
| Brake System | RED | A red brake warning light on your 1025R indicates a problem with the hydraulic brake system, such as low brake fluid or excessive wear. | Check brake fluid reservoir and inspect brake pads; do not operate until the issue is resolved. | |
| Parking Brake | AMBER | An amber parking brake symbol on the 1025R reminds you that the parking brake is engaged and should be released before driving. | Release the parking brake lever fully before moving the tractor. | |
| Glow Plug / Preheat | AMBER | This amber coil icon lights during cold starts on the 1025R to indicate the glow plugs are preheating the combustion chamber. | Wait until the light goes out before cranking the engine; typically takes a few seconds in cold weather. | |
| Low Fuel | AMBER | An amber fuel pump icon on the 1025R glows when the diesel fuel level is low, warning you to refill soon. | Add diesel fuel to the tank as soon as possible to avoid running out and introducing air into the system. | |
| High Beam | BLUE | A blue headlamp symbol on the 1025R indicates that the high-beam headlights are turned on for better visibility. | Switch to low beams when approaching other vehicles or when working in well-lit areas. | |
| PTO Engaged | GREEN | A green PTO symbol on the 1025R shows that the power take-off is engaged and the rear shaft is turning. | Ensure all PTO-driven implements are properly attached and that no one is near the shaft before engaging. | |
| Differential Lock | AMBER | An amber differential lock icon on the 1025R indicates the rear differential is locked for increased traction on slippery surfaces. | Disengage the differential lock when turning or on hard surfaces to prevent driveline damage. | |
| Hydraulic System | AMBER | An amber hydraulic system warning on the 1025R signals low hydraulic oil level or a partially clogged filter. | Check hydraulic fluid level and clean or replace the filter; avoid heavy usage until corrected. | |
| Service / Hour Meter | AMBER | This amber wrench icon on the 1025R appears when a scheduled maintenance interval—like an oil change or filter replacement—is due. | Refer to the operator's manual for the required service and perform it promptly to keep the warranty valid. | |
| Seat Belt | RED | A red seat belt icon on the 1025R reminds you to fasten your seat belt for operator safety, especially on slopes. | Secure the seat belt before operating the tractor. |

Most Important Warning Lights
Engine Overheating
Common causes
- Low coolant level
- Radiator debris or clogged fins
- Faulty thermostat or water pump
What to do
On your 1025R, stop the engine immediately, allow it to cool, then clean the radiator screen with compressed air. Check coolant level in the recovery tank and add a 50/50 mix of antifreeze and water if low.
Low Oil Pressure
Common causes
- Insufficient engine oil level
- Worn oil pump or bearings
- Clogged oil filter
What to do
Shut down the 1025R right away. Check the dipstick and add SAE 15W-40 oil (or recommended grade) to the full mark. If the light persists, have the oil pressure sensor and pump inspected by a dealer.
Transmission Overheating
Common causes
- Prolonged heavy load operation
- Low transmission fluid level
- Blocked transmission cooler
What to do
Reduce the load and drive at lower RPM to cool the hydrostatic transmission. Check the transmission dipstick and add John Deere Hy-Gard fluid if needed. Clean the cooler fins with a soft brush.
Brake Failure
Common causes
- Low brake fluid level
- Worn brake pads or shoes
- Air in the hydraulic brake lines
What to do
Park the 1025R safely and check the brake fluid reservoir beside the steering column. Top off with DOT 3 brake fluid. If the light remains, brake components need replacement or the system must be bled.
Hydraulic System Malfunction
Common causes
- Low hydraulic oil level
- Clogged hydraulic filter
- Leaking hose or fitting
What to do
Inspect the hydraulic oil sight glass on the rear of the 1025R; add John Deere Hy-Gard oil if low. Replace the hydraulic filter (part number LVU4141) if the light stays on. Check for visible leaks.
Frequently Asked Questions
Why does the glow plug light stay on for so long on my 1025R?
In cold weather, the glow plugs need extra time to heat the combustion chamber. On the 1025R, the light may stay on for up to 10 seconds below 32°F. If it stays on longer, the glow plug relay or plugs may need replacement.
What should I do if the master warning light comes on while mowing?
Immediately stop the PTO and drive to a safe spot, then shut off the engine. Check the LCD display for the specific fault code. Common causes include low oil pressure or overheating—address those before restarting.
Does the 1025R have a DEF or DPF warning light?
No, the 1025R is a Tier 4 (non-final) engine that uses a DOC and a passive regeneration system without a DPF or DEF tank. There is no DPF or DEF light on this model.
How do I reset the service light on my 1025R?
After performing scheduled maintenance, turn the key to the ON position without starting the engine. Press and hold the hour meter reset button (on the dash) for 10 seconds until the wrench icon blinks and then turns off.
The PTO light is on but the PTO is disengaged—what's wrong?
Ensure the PTO lever is fully in the disengaged position. If the light remains on, the PTO switch may be faulty or the clutch plate is sticking. Have a dealer check the electrical switch and mechanical linkage.
Why does the hydraulic warning light come on when using the loader?
When operating the loader heavily, the hydraulic oil heats and expands, which can trigger the low-level sensor if the oil is slightly low. Top off the hydraulic fluid with Hy-Gard to the proper level on the sight glass.
