Description
A 4 stroke brush cutter is a powerful petrol-powered machine designed for cutting grass, weeds, shrubs and light bushes in farms, gardens, roadsides and commercial landscapes. Unlike traditional 2-stroke models, a 4-stroke brush cutter runs on pure petrol, with engine oil kept separately in the crankcase. This results in lower fuel consumption, quieter operation, reduced exhaust emissions and longer engine life.
The machine can be fitted with different cutting attachments such as a nylon trimmer head, metal grass blade, brush blade or circular saw blade, making it suitable for both light trimming and heavy vegetation clearing.
Modern 4-stroke brush cutters are widely used by landscapers, farmers, contractors, county maintenance teams and homeowners because they combine reliable performance with improved fuel efficiency. Typical engine sizes range from 35 cc to 50 cc, producing approximately 1.0–1.8 kW of power, depending on the model.
