The Cub Cadet LM1 AP46 features a four-stroke gasoline engine that rotates the cutting blades. An important advantage over other engines is the increased power and torque for many hours of work on large areas. Inevitably, engines of this type have some disadvantages such as noisy operation 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 fuel 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 designed to withstand more wear and tear.
• They produce less noise and vibrations during operation.
• They are less polluting because they do not require the mixing of oils or lubricants with fuel.

Disadvantages:

• Due to the fact that lawn mowers with four-stroke engines have more components and valves, repairs and maintenance are more expensive.
• Since they only generate power as the piston rotates every four revolutions, this design is less powerful than an engine with a similar two-stroke engine.

The cutting height can be adjusted from 28 to 92 mm.

• Read the user manual carefully 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, seat belts, and engine operation.
• Wear appropriate clothing and protective accessories such as gloves, goggles, and helmet.
• Pay attention to the area around the machine and make sure there are no children, pets, or other objects in its path.
