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 Nakayama Pro PM5860 lawn mower is a self-propelled gasoline-powered mower, so it does not require electricity, allowing you to work remotely.

The gasoline engine it features 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 an oil and air circulation 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 vibrations 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 can be adjusted to 6 different positions, from 25 to 75 mm, making it extremely easy to best adapt the machine to the height of the grass.

The four-stroke Euro 5 engine is an internal combustion engine that meets the specifications of the Euro 5 emission regulations. The Euro 5 regulations are a series of regulations that impose stricter limits on vehicle pollutant emissions.

Euro 5 engines are designed to reduce pollutant emissions through the use of more efficient combustion systems and fuels. This means that these engines emit less CO2 and other pollutants into the atmosphere compared to older generations of engines.

Overall, the four-stroke Euro 5 engine is a more environmentally friendly option for a vehicle, as it reduces its impact on the atmosphere and climate.

The consumption of the Nakayama Pro is reduced by up to 40% and it has lower exhaust emissions due to better combustion.
