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 PM4830 features a gasoline engine, which 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 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 the mixing of 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 four-stroke Euro 5 engine is an internal combustion engine that meets the emission standards of the Euro 5 regulations. The Euro 5 regulations are a series of rules 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.

The 65-liter collector bag allows you to mow for extended periods before needing to stop and empty the bag.

The cutting height can be adjusted to 6 different positions, from 22 to 65 mm.

The self-propelled lawn mower is used for cutting grass in large gardens and rural areas. To use it safely and effectively, follow these instructions:

• Carefully read the user manual and follow all instructions for starting, using, and maintaining the machine.
• Before you start using it, check all functions and safety systems such as brakes, safety belts, and engine operation.
• Wear appropriate clothing and protective gear such as gloves, glasses, and a helmet.
• Be aware of the area around the machine and ensure there are no children, pets, or other objects in its path.
