Key Considerations When Choosing a Self-Propelled Petrol Lawn Mower for Large Gardens
When selecting the right mower, keep the following factors in mind:
- Engine Power and Type: More powerful engines (above 150 cc) are better for larger gardens and tougher grass. Consider the type of engine as well; Honda and Briggs & Stratton engines are known for their reliability and efficiency.
- Cutting Width: Wider cutting widths (above 50 cm) cover more ground quickly, making them ideal for large lawns.
- Drive System: Variable speed self-propelled systems provide more control and comfort, especially on uneven or sloped terrains.
- Grass Collection Capacity: Larger grass bags (70 liters and above) reduce the need for frequent emptying, which is a big plus for large gardens.
- Durability and Build Quality: Look for robust materials like aluminium or high-grade steel decks that can withstand heavy use and rough terrains.
