Listen to Your Machine: How to Recognize Worn Parts in Agricultural Machinery? A Guide from GĄSKA Company

Every agricultural machine, even the highest quality and regularly serviced, undergoes natural operational wear over time. The key to avoiding serious, costly breakdowns and unplanned downtime during the busiest field work period is the ability to recognize early symptoms indicating the wear of individual components. At GĄSKA, as your partner in the field of agricultural machinery parts, we believe that knowledge and awareness in this area are fundamental to efficient and safe farming. We have prepared a practical guide to help you “listen” to the signals sent by your equipment.

Why is Early Recognition of Wear So Important?

Ignoring the first, often subtle, signs of wear is a direct path to escalating the problem. A small defect, if not addressed in time, can lead to:

• More serious damage: A worn part can cause the failure of other, more expensive components (the so-called domino effect).
• Costly repairs: Repairing an advanced failure is always more expensive than replacing a single, worn part.
• Dangerous situations: Damaged brakes, play in the steering system, or cracked elements can lead to accidents.
• Decreased machine efficiency: The equipment does not operate at optimal efficiency, which translates into losses of time and fuel.
• Shortening the lifespan of the entire machine.

Your Senses – The Best First-Contact Diagnostic Tools

Before you reach for specialized diagnostic tools, use what you always have with you – your own senses. Regular and careful observation of the machine can reveal a lot:

Sight – What Can You See?

• Fluid leaks: Traces of oil (engine, hydraulic, gear), coolant, fuel under the machine or on its components. Look for fresh spots, streaks, or dampness.
• Cracks and deformations: On frames, housings, working elements, welds.
• Excessive wear: Worn surfaces, material loss on gear teeth, knives, shares, chains.
• Corrosion: Advanced rust on key structural or moving elements.
• Damaged lines: Cracks, abrasions, kinks in hydraulic, fuel, or electrical lines.
• Loose or missing elements: Bolts, nuts, pins, covers.
• Color change: Overheated metal parts can change color. Smoke from the exhaust pipe (white, blue, black) can indicate various engine problems.
• Tire condition: Uneven tread wear, cracks, bulges.

Hearing – What Can You Hear?

• Unusual sounds during operation:
  • Knocking, tapping: May indicate play in the engine, suspension, or gears.
  • Squealing, whistling: Often related to worn or poorly tensioned V-belts, turbocharger problems, or leaks in the intake system.
  • Grinding, friction: May indicate worn bearings, problems with the clutch, brakes, or transmission.
  • Whining, humming: Often a symptom of a worn hydraulic pump, wheel bearings, or other rolling elements.
• Uneven engine operation: “Coughing,” misfiring, difficulty maintaining RPMs.
• Change in operating volume: Sudden silencing or louder operation of a specific component.

Touch (and Sensations) – What Can You Feel (Exercise Caution!)?

• Excessive vibrations: Noticeable on the steering wheel, floor, control levers – may signal imbalance of rotating elements, play, or tire problems.
• Excessive play: Check (on a switched off and secured machine!) for play in wheels, steering system components, suspension, shaft bearings.
• Elevated temperature: After operation, carefully touch (or use a non-contact thermometer) bearing housings, hubs, engine, gearbox. Excessive heat is a sign of friction, lack of lubrication, or overload.
• Resistance during steering: Hard-to-operate steering wheel, gear shift levers, pedals.

Smell – What Can You Smell?

• Smell of burning: May come from an overheating clutch, brakes, electrical system, or burning oil.
• Smell of fuel or oil: Indicates leaks.
• Sweet smell of coolant: May indicate a leak in the cooling system.

Observation of Operation – How is the Machine Working?

• Decrease in power and performance: The machine reacts slower, has trouble climbing hills, its work output decreases.
• Problems starting the engine.
• Increased fuel or oil consumption.
• Hydraulic problems: Slow lifting/lowering of implements, lack of power, “foaming” of oil.
• Improper operation of working elements: E.g., the seeder sows unevenly, the baler ties poorly, the combine loses grain.
• Braking problems: Extended braking distance, pulling to one side.

Examples of Symptoms for Specific Part Groups:

• Bearings: Noise (hum, whine, friction), radial or axial play, vibrations, overheating.
• V-belts/Multi-rib belts: Squealing (especially when starting or changing load), visible cracks, frayed edges, worn working surface.
• Filters: (Often no direct symptoms from the filter itself, but the effects of its clogging) Decreased engine power (air, fuel filter), oil pressure problems (oil filter), incorrect hydraulic operation (hydraulic filter).
• Cutting elements (knives, blades): Dulled edges, chipping, cracks, uneven cutting, increased power demand.
• Clutch: Slipping (engine RPMs increase, but speed does not), jerking when starting, difficulty changing gears, smell of burning.

What to Do When You Notice Alarming Symptoms?

1. Don’t ignore the signals! Even a minor symptom can be a precursor to a bigger problem.
2. Stop the machine in a safe place and turn off the engine before a more thorough inspection.
3. Try to locate the source of the problem. Compare your observations with the information in the operating manual.
4. Assess the seriousness of the situation. Can you continue working, or does the problem require immediate intervention?
5. If in doubt, consult an experienced mechanic or specialist.
6. Plan the replacement of the damaged or worn part. Contact GĄSKA – we will help you select the right components and ensure their quick delivery.
