Common Mistakes And Misconceptions
| Mistake/Misconception | Correct Viewpoint |
|---|---|
| 2-stroke engines are more powerful than 4-stroke engines. | This is not necessarily true as the power output of an engine depends on various factors such as its size, design, and intended use. Both types of engines can be designed to produce high levels of power. |
| Zero-turn mowers with 2-stroke engines are cheaper than those with 4-stroke engines. | The cost of a zero-turn mower depends on several factors such as brand, model, features, and engine type. While some models with 2-stroke engines may be less expensive than those with 4-stroke engines, this is not always the case and should not be assumed without proper research. |
| Maintenance for a zero-turn mower with a 2-stroke engine is easier than that for one with a 4-stroke engine. | The maintenance requirements for any machine depend on its specific design and components rather than just the type of engine it has. Some models may have simpler or more complex maintenance needs regardless of their engine type so it’s important to check the manufacturer‘s recommendations before making assumptions about ease-of-maintenance based solely on the type of engine used in a particular model. |
| A zero-turn mower with a 2-stoke engine will last longer than one with a four stroke-engine. | The lifespan of any machine depends on many factors including how well it is maintained over time, how often it is used and under what conditions (e.g., wet vs dry grass), etc.. Neither two nor four stroke-engines inherently last longer or shorter periods; both can provide long-lasting performance if properly cared for by their owners. |
