Help with Mower Faults
These answers help you describe a fault and identify the next appropriate check. Keep the machine safely stopped for diagnosis and follow its manual before inspection or clearing work.
What should I check if nothing happens when I try to start?
Keep the cutting system in its safe starting state and follow the manual's checks for power, emergency-stop position, controller status and starting interlocks. Note whether there is a display, click or starter movement. Avoid bypassing protective controls. If the cause is not clear, send the model and observed symptoms to support.
Why does the starter turn but the engine not fire?
Possible causes include fuel supply, the starting procedure, ignition, air supply or an engine protection condition. Use the exact engine's fault guidance and note whether the problem began after storage, refuelling or service. Avoid repeated long cranking or improvised fuel tests. Further diagnosis should follow the manual or a qualified technician's instructions.
Why does the engine stall when the blades engage?
Heavy cutting load, obstruction, an engagement problem, belt or bearing resistance, or reduced engine output can contribute. Stop and isolate before examining the cutting system. Note whether it happens without vegetation or only under load. Do not defeat an interlock or repeatedly re-engage a head that may be obstructed.
Does exhaust smoke mean the engine is damaged?
Smoke has several possible causes, including the operating condition, fuel, oil level or a mechanical fault. Its colour, duration and associated symptoms help diagnosis, but colour alone is not conclusive. Stop if smoke is abnormal, persistent or accompanied by loss of power, leaks or unusual noise, and follow engine-specific service guidance.
What should I do if the engine or controller overheats?
Stop work and follow the shutdown and cooling procedure. Check only the items the manual permits, such as debris around cooling paths, after the machine is safe. Record warning indications and the conditions before overheating. Continuing under the same load without finding the cause can produce further damage.
What should I do about sudden strong vibration?
Stop the cutting work and shut down safely. After isolation and complete cessation of movement, inspect according to the manual for damaged or missing tools, loose connections, trapped material or other visible defects. Keep the machine out of service if the cause is uncertain. Do not run it repeatedly to see whether severe vibration disappears.
Why does the mower leave strips or an uneven cut?
Check the cutting height, travel rate, overlap, tool wear and ground condition. Bent, missing or incorrectly fitted tools can also affect the result. Inspect only after safe shutdown. If the issue starts suddenly or includes abnormal vibration, address the mechanical cause before changing the mowing pattern.
How do I remove wire or wrapped vegetation from the rotor?
Stop, isolate and secure the machine using the manual, then wait for all movement to cease. Use the specified safe access and clearing method. Never reach into an energised or unsupported cutting head. Wire may be under tension; uncertain or difficult clearing should be handled with appropriate technical assistance.
What should I do if a track comes off or one side stops moving?
Stop the cutting work and secure the machine against movement by the approved procedure. Do not stand in a position where it could move onto you. Debris, track adjustment, drive components and electrical faults can require different repairs. Record the symptoms and obtain the model-specific recovery or service procedure before attempting further operation.
How can I describe a remote-control or low-voltage fault?
Record the machine model, transmitter status, battery indication and which functions respond. Explain whether the fault appeared during travel, cutting, starting or after storage. Low voltage, pairing and a control fault can look similar from a single symptom. Use the manual's checks and keep the machine safely stopped during diagnosis.
