As the South African summer fades, our lawns (dominated by hardy species like Kikuyu and Buffalo grass) begin to slow their growth. For many homeowners, this is the signal to put the mower away. However, simply pushing your machine into the back of the garage until September is a recipe for expensive repairs come spring.

At Smith Power Equipment, we know that the harsh South African climate, from the dusty Highveld winters to the humid coastal air, can take a toll on your machinery. Here is how to troubleshoot common problems and ensure your mower survives the winter.

Quick Troubleshooting Guide

If you are facing an immediate issue, use this table to find a fast solution:

1. The Engine Won’t Start

The most common frustration in South Africa is a “dead” mower. Because our fuel can degrade quickly in the heat, “stale” petrol is often the culprit.

• The Fix: Drain old fuel and replace it with fresh petrol. Check the spark plug for carbon buildup. If the plug is black or oily, it is time for a replacement.
• Pro Tip: If you have an electric-start model, ensure the battery is charged, as cold winter nights can drain lead-acid batteries quickly.

2. Poor Cutting Performance

Does your lawn look “frayed” or brown at the tips after mowing? This usually means your blades are tearing the grass rather than cutting it.

• The Fix: Always disconnect the spark plug wire first, then tip the mower with the carburettor side facing up to inspect the blades. Sharpen them or replace them if they are notched.
• Local Factor: Thick South African Kikuyu grass requires sharp blades to maintain a healthy lawn.

3. Engine Stalling or Running “Rough”

If your engine “hiccups” or loses power in thick grass, it is likely gasping for air.

• The Fix: South Africa is dusty. Check your air filter regularly. A clogged filter starves the engine of oxygen, leading to overheating and stalling. Clean or replace it before winter storage.

4. Excessive Smoke

Do not panic yet.

• White Smoke: This usually means you tilted the mower the wrong way and oil leaked into the exhaust. It should burn off after a few minutes of use.
• Black Smoke: This indicates the engine is burning too much fuel. Check the air filter immediately.

Winter Storage Checklist: 5 Steps to a Perfect Spring Start

Preventative care is the best way to extend the life of your equipment. Follow these steps before the first winter frost:

1. Stabilise the Fuel: Petrol left in a tank for three months turns into a gummy residue that clogs carburettors. Either drain the tank or add a fuel stabiliser.
2. Clean the Under-Deck: Dried grass traps moisture, which leads to rust and corrosion on your mower deck. Scrape it clean before storing.
3. Oil Change: Winter is the perfect time to change the oil. Fresh oil protects internal engine components from corrosion during the damp months.
4. Battery Care: For battery-powered or electric-start mowers, store the battery in a cool, dry place. Avoid leaving it on a cold concrete floor, as this can discharge it.
5. Lubricate: Apply a light lubricant to any moving cables or pivot points to prevent them from seizing up in the dry winter air.

When to Call the Professionals

While DIY maintenance is great for minor issues, certain problems require the specialized tools and expertise of a technician:

• Crankshaft Damage: If you hit a stump or rock and the mower vibrates violently.
• Electrical Failures: Complex wiring issues in modern electric mowers.
• Internal Engine Knocking: This could signal a major mechanical failure.
