| Light-Duty Flexible Shaft | 25–27 cc, approximately 0.7–0.9 kW, 2-stroke gasoline engine | Nylon line head; optional 2- or 3-tooth blade | 40–45 cm with line; 20–25 cm with blade | Approximately 6.0–7.5 kg, excluding fuel and cutting attachment | 0.5–0.7 L | Grass, lawn edges, light weeds and residential maintenance | Lower transport weight and fuel use; confirm local noise, emissions and safety requirements before import. |
| Balanced General-Purpose Model | 30–33 cc, approximately 0.9–1.2 kW, 2-stroke gasoline engine | Nylon line head plus 3-tooth grass blade | 40–46 cm with line; 23–25 cm with blade | Approximately 6.5–8.5 kg, excluding fuel and cutting attachment | 0.6–0.8 L | Mixed grass, weeds, field margins and routine landscaping | A practical balance of power, portability and operating time for multiple climate zones and terrain types. |
| Heavy-Duty Brush-Cutting Model | 35–40 cc, approximately 1.2–1.6 kW, 2-stroke gasoline engine | 3- or 4-tooth metal blade; reinforced line head where permitted | 40–45 cm with line; 23–25 cm with blade | Approximately 7.5–10.0 kg, excluding fuel and cutting attachment | 0.7–1.0 L | Dense weeds, tall grass, scrub and demanding commercial maintenance | Higher productivity and cutting capacity; evaluate harness quality, vibration control and spare-part availability. |
| Low-Emission 4-Stroke Configuration | 30–35 cc, approximately 0.8–1.1 kW, 4-stroke gasoline engine | Nylon line head and grass blade, depending on configuration | 38–45 cm with line; 20–25 cm with blade | Approximately 7.5–10.5 kg, excluding fuel and cutting attachment | 0.6–0.8 L gasoline tank; engine oil reservoir is separate | Noise-sensitive areas, municipal work and users preferring gasoline-only fueling | Usually heavier than comparable 2-stroke units; check oil-service procedures and destination-country emissions rules. |
| Professional Long-Run Configuration | 35–45 cc, approximately 1.3–1.8 kW, 2-stroke gasoline engine | Metal brush blade, saw blade where approved, and heavy-duty line head | 40–48 cm with line; 23–30 cm with blade | Approximately 8.0–11.0 kg, excluding fuel and cutting attachment | 0.8–1.2 L | Contract landscaping, roadside vegetation and extended daily operation | Prioritize serviceable flexible shafts, replaceable clutch components, ergonomic harnesses and reliable parts logistics. |
