Engine configurations and cutter attachments
Modern brush cutters support diverse cutting heads tailored to specific vegetation.
Key equipment configurations:
- 2-Stroke engines: Lightweight and high-revving, running on petrol-oil mixes; well-suited for steep hillsides and terraced orchards.
- 4-Stroke engines: More fuel-efficient, produce lower exhaust fumes, operate with less vibration, and use separate engine oil reservoirs.
- Circular saw blades (40T/80T): Carbide-tipped circular blades fitted with crop collectors for harvesting wheat, paddy, and fodder crops.
- 2-Tooth and 3-tooth metal blades: Heavy-duty blades designed for slashing thick woody brush, cotton stalks, and tough perennial weeds.
- Nylon trimmer heads: Flexible monofilament nylon lines for trimming tender lawn grasses and weeds along stone borders and tree trunks.
Safe operational guidelines and protective gear
Operating high-speed cutting implements requires strict protective measures.
Essential safety practices:
- Always wear a full face shield or safety goggles, hearing protection earmuffs, heavy-duty gloves, and sturdy protective work boots.
- Adjust the double-shoulder harness so the machine's balance point rests naturally at your hip without straining your back.
- Maintain a minimum safety distance of 15 metres from bystanders and livestock to prevent injury from thrown pebbles.
- Inspect and tighten blade lock-nuts and deflector shields before starting field operations.
Maintenance routines and SMAM government subsidy
Clean the air filter after every 10 hours of operation, lubricate the bevel gear head with lithium grease every 25 hours, and drain stale fuel before off-season storage. Small and marginal farmers can avail purchase subsidies under the Sub-Mission on Agricultural Mechanization (SMAM) at agrimachinery.nic.in.

Common questions
Can a grass cutting machine be used to harvest wheat and paddy?
Yes, using an 80-tooth or 40-tooth circular alloy blade fitted with a crop collection guard allows efficient harvesting of wheat and paddy crops.
What is the difference between a 2-stroke and 4-stroke brush cutter?
2-stroke models are lighter and require petrol mixed with 2T oil, while 4-stroke engines run on pure petrol, have better fuel economy, and produce lower noise.
Is government subsidy available for grass cutting machines in India?
Yes, capital subsidies are available under the SMAM scheme and state agriculture department mechanization portals via agrimachinery.nic.in.
