Heavy-Duty Farm Brush Cutters & Trimmers
Explore 2-stroke & 4-stroke sidepack and backpack models (35cc, 52cc, 58cc) with crop harvest blades, tap-and-go nylon heads, and COD.
Choosing between a 2-stroke (52cc/58cc) and a 4-stroke (35cc GX-35 type) brush cutter is the single most common decision Indian farmers face when clearing weeds, trimming bunds, or harvesting fodder.
Key Differences for Field Work
| Feature | 2-Stroke (52cc / 58cc) | 4-Stroke (35cc / 50cc) |
|---|---|---|
| Power & RPM | 9,000–10,500 RPM (High snap torque) | 7,000–8,000 RPM (Smoother, linear) |
| Weight | 7.5 kg (Lighter, easier on bunds) | 9.0–10.2 kg (Heavier engine block) |
| Fuel Requirements | Petrol + 2T Oil (40:1 ratio) | Pure Petrol + Sump Oil (Separate) |
| Field Slopes | 360° operation without oil starvation | Risk of oil starvation if tilted >45° |
2T Oil Mixing Precautions
If you choose a 2-stroke machine, never guess the oil ratio by eye. Running lean (e.g. 60:1) seizes the piston rings within 15 hours. Running too rich (e.g. 15:1) fouls the spark plug with black carbon.
