🧠 What to Look For in a Slope-Capable Petrol Mower

🚜 1. Self-Propelled Drive Is Key

A self-propelled mower helps pull itself forward, reducing the physical effort required when mowing uphill or over uneven ground. Look for models with adjustable drive speeds so you can match your walking pace.

---

🛞 2. Large, Treaded Wheels Improve Traction

Bigger wheels with deep, grippy tread help keep traction on slopes and uneven patches. Rear wheels slightly larger than front wheels make steering and stability easier on banks.

---

⚡ 3. Strong Engine Power (≥125 cc)

Slopes and thick grass both demand torque. Engines of 125 cc or more deliver the grunt needed to maintain cutting speed without bogging down.

---

📏 4. Adjustable Cutting Heights

Sloped gardens can have varied grass lengths. A mower with multiple cutting heights gives you better control when adjusting to different ground contours.
