With self-propulsion, all you need to do is press a lever located on the handlebar to transfer the motion generated by the engine to the wheels, resulting in the machine moving on its own.

The lawn mower features a four-stroke gasoline engine that 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, exhaust emissions, and high usage and maintenance costs.

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 components 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.

The cutting height adjustment is done centrally via a lever and can be adapted according to the needs of the garden, from 35 to 75 mm.
