Check battery terminals, wiring, drive belts, and charging voltage if this light remains on.

Best for: Electrical maintenance, battery testing, charging system inspections.

Engine Coolant Temperature Warning: Preventing Overheating

When the coolant temperature symbol turns red, the engine is overheating.

Common causes include:

• Low coolant
• Dirty radiator
• Faulty thermostat
• Cooling fan problems
• Blocked airflow

Allow the engine to cool before opening the radiator cap. Never remove the cap while the engine is hot.

Best for: Cooling system maintenance, engine safety, seasonal inspections.

Fuel Warning Light: Time to Refuel

The fuel symbol appears when the fuel tank reaches a low level.

Running completely out of fuel can introduce air into diesel fuel systems, requiring additional priming before restarting.

Planning refueling before the warning appears helps avoid unnecessary downtime.

Best for: Fuel management, long workdays, field operations.

PTO Indicator: Power Take-Off Status

The PTO icon shows whether the Power Take-Off is engaged.

This reminder helps prevent accidents while attaching or removing implements such as mowers, balers, tillers, or rotary cutters.

Always confirm the PTO is disengaged before servicing attached equipment.

Best for: Equipment safety, mowing, baling, tilling, implement operation.

Four-Wheel Drive Indicator: Extra Traction

The 4WD symbol confirms that four-wheel drive is active.

Using 4WD improves traction on muddy fields, steep slopes, loose soil, or snowy conditions. However, many tractors recommend disengaging it during normal road travel to reduce tire wear.

Best for: Farming, snow removal, loader work, difficult terrain.

Parking Brake Indicator: Secure Parking

This dashboard symbol reminds the operator that the parking brake is engaged.

Driving with the brake applied can reduce performance and increase brake wear. Before moving, always verify the indicator has turned off.

Best for: Safe parking, loading, transport, maintenance work.

Hydraulic System Warning: Fluid Pressure Alert

Hydraulic systems power loaders, steering, and many implements. A hydraulic warning light may indicate:

• Low hydraulic fluid
• Pump issues
