Repair garden machinery.

Neglecting these machines often leads to difficult starting, poor cutting performance, and eventually, expensive engine failure. Professional repair and servicing not only extend the life of your equipment but also prevent the frustration of a breakdown when the weather finally clears for gardening.

What Does the Work Involve?

• Full Diagnostic Inspection: Checking for mechanical wear, fuel leaks, and electrical faults.
• Engine Servicing: Draining old oil, replacing air and fuel filters, and installing new spark plugs.
• Blade Maintenance: Professional sharpening and precision balancing of mower blades or hedge trimmer teeth.
• Fuel System Cleaning: Removing "stale" fuel deposits and cleaning the carburettor to improve starting.
• Drive System Check: Inspecting and adjusting belts, cables, and gearboxes on self-propelled models.
• Safety Testing: Ensuring operator presence controls (dead man's handles) and guards are functioning correctly.

Typical Costs

Prices are primarily influenced by the complexity of the machine and the cost of genuine manufacturer parts. High-end brands like John Deere or Honda may incur higher parts costs compared to budget supermarket brands, while mobile "on-site" repairs often carry a premium for convenience.

How Long Does It Take?

• Routine Service (Small Tools): 1 to 2 hours for handheld equipment like chainsaws or trimmers.
• Standard Mower Service: 2 to 3 hours, including blade sharpening and oil changes.
• Complex Engine Repair: 3 to 5 hours, depending on whether the carburettor needs ultrasonic cleaning.
• Ride-on Mower Full Service: 4 to 6 hours due to multiple blades and complex drive systems.
• Parts Lead Times: If specific components aren't in stock, wait times can extend by 3 to 7 working days.

DIY or Professional?

Homeowners can easily handle basic tasks like cleaning the deck, checking oil levels, and replacing simple air filters. However, engine diagnostics and blade balancing require specialised tools and knowledge of "torque settings" to ensure the machine is safe to operate.

Warning: Never attempt to repair a chainsaw or the internal components of a high-voltage cordless mower battery unless you are specifically trained, as the safety risks are significant.

Professional technicians have the equipment to safely dispose of hazardous waste like old engine oil and stale petrol, which cannot be put in domestic bins. For petrol machinery, a professional "tune-up" often pays for itself through improved fuel efficiency and easier starting.

Choosing the Right Tradesperson

• Brand Authorisation: Check if they are an authorised service centre for your specific brand (e.g., Stihl, Husqvarna, Mountfield).
• Insurance: Ensure the technician or workshop has public liability insurance and "goods in trust" insurance if they take your machine away.
• Warranty: Ask if they provide a guarantee on both the labour and the parts fitted (typically 3–6 months).
• Questions to Ask: Do you use genuine OEM parts or cheaper pattern parts? Is there a diagnostic fee if the machine is beyond economical repair? How do you dispose of old oil and fuel?

UK Regulations

• PUWER (1998): While mainly for commercial use, these regulations set the standard for the safe maintenance of work equipment in the UK.
• Waste Regulations: Professionals must follow strict rules for the disposal of hazardous liquids like engine oil and lead-acid batteries.
• Noise & Emissions: Modern machinery must meet specific UKCA/CE standards; a professional will ensure your machine isn't running "rich" and producing excessive fumes.

Common Problems

• Stale Fuel: Modern E10 petrol degrades within 30 days, causing gumming in the carburettor; always use a fuel stabiliser or drain the tank for winter.
• Unbalanced Blades: Sharpening a blade unevenly causes severe vibration, which can snap the crankshaft or destroy engine bearings.
• Blocked Air Filters: A common cause of "hunting" (the engine speed surging up and down) and overheating.
• Incorrect Oil: Using car oil instead of specific 4-stroke garden machinery oil can lead to premature engine wear in air-cooled engines.
• Snapped Pull Cords: Often caused by "kickback" from a bent blade or timing issues, rather than just a weak rope.
