🔥 Petrol Lawn Mowers

🧠 Overview

Petrol lawn mowers are driven by a small combustion engine and don’t need cables or batteries. They’re powerful, good for large lawns, and handle thick, damp, or uneven grass well.

✅ Pros

• High power & torque — excellent for tough grass and large spaces
• No run-time limits — just add fuel and keep mowing
• Great for slopes & uneven terrain
• Durable & long-lasting with regular maintenance

❌ Cons

• Heavier and louder than electric/cellular models
• Requires petrol storage and engine care
• Higher emissions and less eco-friendly
• More maintenance (spark plugs, filters, oil changes)

🔍 Best For

• Large lawns (500 m²+)
• Thick, long, or damp grass
• Slopes and rough ground
• Gardeners prioritising power and stamina

⚡ Electric (Corded) Lawn Mowers

🧠 Overview

Electric mowers plug into a mains socket with a cable. They offer a continuous power supply without petrol, but the cable can limit reach.

✅ Pros

• Low noise compared to petrol
• No fuel or battery charging needed
• Cleaner operation with zero emissions at the mower
• Low maintenance

❌ Cons

• Cable limits movement — not great for large lawns
• Cord safety needed to avoid cuts as you mow
• Less power than petrol for very thick grass

🔍 Best For

• Small to medium lawns (especially flat)
• Gardens close to power outlets
• Mowers who want fewer moving parts and simple upkeep

🔋 Cordless (Battery) Lawn Mowers

🧠 Overview

Cordless mowers use rechargeable batteries (usually lithium-ion). In 2026 the tech has improved — offering longer run times and stronger motors — but there are trade-offs.

✅ Pros

• No cables — full freedom of movement
• Quieter than petrol
• Zero on-site emissions
• Low maintenance — no fuel or cords

❌ Cons

• Run-time limits — depends on battery size and condition
• Slower on thick or wet grass than petrol
• Batteries degrade over years and are costly to replace
• Higher upfront price for good performance models

🔍 Best For

• Small to medium lawns
• Gardeners who value convenience and low noise
• Spaces near storage so batteries can recharge easily
