This model features a four-stroke engine. The machine is powered by gasoline and does not require electricity, so you can work remotely.

The gasoline engine rotates the cutting blades. A significant advantage over other engines is the increased power and torque for many hours of work on large areas. Inevitably, this type of engine has some disadvantages such as noisy operation, emission of exhaust gases, and high cost of use and maintenance.

What is a four-stroke engine and what are its advantages/disadvantages in a lawn mower?

It is an internal combustion engine that operates with a circulation of oil and air in four operating cycles.

Advantages:

• Lawn mowers with four-stroke engines do not require additional oil.
• They consume fuel only once every four strokes, making them a more economical choice.
• They are built to withstand more wear and tear.
• They produce less noise and vibration during operation.
• They are less polluting because they do not require mixing oils or lubricants with the fuel.

Disadvantages:

• Because lawn mowers with four-stroke engines have more parts and valves, their repairs and maintenance are more expensive.
• Since they get their power only as the piston rotates every four strokes, this design is less powerful than a similar two-stroke engine.
