In the competitive field of brushcutter retailing, knowing your product inside and out is critical. As a delars, you sell not only tools, but also solutions for landscape designers and gardeners. The two major players in this space are two-stroke and four-stroke brush cutters—similar in appearance, but very different in performance and application.
This article aims to dissect the core differences between these two brush cutters to give you the knowledge to make an informed purchasing decision. Whether your customers are professional landscapers who demand high performance or home gardeners who prioritize ease of use, understanding each brush cutter's unique attributes, advantages and potential disadvantages can reshape your inventory strategy. Read on to learn about the special features of two-stroke and four-stroke brush cutters.
Generally speaking, brush cutters run on two types of engines, two-stroke or four-stroke. Brush cutter engine is simply an internal combustion engine.
A cycle is the number of strokes a piston completes in an internal combustion engine. A four-stroke engine needs four strokes of the piston to burn fuel and generate power:
Intake: Downstroke draws in fuel
Compression: Upstroke expels exhaust gasses
Combustion (power): Another downstroke brings more fuel and ignites it
Exhaust: Another upstroke compresses and expels fuel
Two-stroke brush cutters cut the number of strokes in half by combining compression and ignition on the upstroke while simultaneously combining power and exhaust on the downstroke. Two-stroke engine requires only two efficient steps (and fewer moving parts) to generate power:
Ignition/compression: The piston moves up, sucking in fuel and compressing it
Combustion/Exhaust: When fuel is ignited, the piston is forced down, expelling exhaust gasses.
Under the same conditions, the internal structure of the four-stroke engine is complex, and the overall weight will be 0.3-0.7kg heavier than the two-stroke engine, which is also reflected in the overall weight of the brush cutter. For long-term professional users, the 4-stroke brush cutter may be more laborious. Considering the weight, many users choose two-stroke brush cutters.
Regarding the comfort of use, the four-stroke brush cutter’s overall low exhaust, low vibration, and low noise will be better than the two-stroke brush cutter. Pull cord reels are also a factor that many people will consider, and four-stroke brush cutters will also be easier to pull and start better than two-stroke brush cutters.
Two-stroke engines require a mix of oil and fuel that is pre-mixed before being added to the engine. This can be a bit more complicated and messier than dealing with a four-stroke engine. On the other hand, four-stroke engines have separate compartments for oil and fuel, making them easier and cleaner to handle.
Generally, two-stroke brush cutters are often less expensive due to their simpler design and fewer moving parts. They also tend to be more lightweight, which might be a consideration for cost as well.
Four-stroke engines are much more efficient due to less fuel demand. Fuel is consumed every four strokes, not every two strokes. Four-stroke engines are best for the environment because of reduced emissions. However, two-stroke engines can generate more torque at higher RPMs, which might make them more effective for certain kinds of heavy-duty work.
|Two-Stroke brush cutter||Four-Stroke brush cutter|
|Weight||Lighter due to fewer moving parts, making them easier to maneuver.||Heavier because of more complex engine components.|
|Ease of Use||Generally easier to start and operate due to simpler design.||May require a bit more effort to start, but typically run smoother.|
|Oil||Requires a mix of oil and fuel that is pre-mixed before being added to the engine. This can be messier.||Has separate compartments for oil and fuel, making it cleaner and easier to handle.|
|Price||Typically less expensive because of their simpler design.||Generally more expensive due to their more complex design and better performance.|
|Efficiency||Can generate more power for their size, but tend to run less efficiently overall. They also produce more emissions.||More efficient at both low and high speeds, produce less exhaust, making them more environmentally friendly.|
Choosing between 2-stroke and 4-stroke brush cutters depends on the specific needs of your project. Two-stroke brush cutters are generally simpler, lighter, and more compact, ideal for hand-held power tasks, and easier to service due to fewer moving parts. They also generally produce more torque at higher rpm. On the other hand, four-stroke brush cutters offer better user comfort due to lower exhaust, vibration and noise levels. They also tend to be cleaner and produce higher torque at lower rpm.
