Engine types and cutting attachments
Matching the engine configuration and attachment to the field job ensures fuel efficiency and high cutting performance.
Key options include:
- 2-Stroke engines: Lightweight, operate at high RPMs on a petrol-2T oil mixture, making them well-suited for steep terraced fields.
- 4-Stroke engines: More fuel-efficient, produce fewer exhaust emissions, operate with reduced vibration, and run on pure petrol with a separate oil sump.
- Circular saw blades (40T/80T): Carbide-tipped blades paired with crop collector shields for harvesting wheat, paddy, and fodder crops.
- 3-Tooth and 2-tooth metal blades: Ideal for slashing thick woody brush, cotton stalks, and tough perennial weeds.
- Nylon trimmer heads: Used for trimming tender lawn grasses, field bunds, and orchard edges near tree trunks.
Safe operation and protective equipment
Motorized cutting equipment requires disciplined safety measures during field operation.
Essential safety practices include:
- Always wear face shields or safety goggles, hearing protection, sturdy work boots, and protective leg guards.
- Inspect the cutting attachment before starting to ensure nuts and locking washers are tightened securely.
- Maintain a minimum clearance distance of 15 metres from bystanders and livestock to prevent flying stone injuries.
- Use the double-shoulder harness properly adjusted to distribute tool weight evenly across the torso.
Maintenance routines and government subsidy
Regularly clean the air filter element, inspect the spark plug gap, and inject lithium grease into the bevel gear case every 25 operating hours. Drain stale petrol from the carburetor before off-season storage. Small and marginal farmers can avail purchase subsidies under the Sub-Mission on Agricultural Mechanization (SMAM) via agrimachinery.nic.in.

Common questions
Can a brush cutter be used to harvest wheat and paddy?
Yes, using a 40-tooth or 80-tooth circular alloy blade fitted with a crop collector attachment allows efficient cereal crop harvesting.
What is the difference between 2-stroke and 4-stroke brush cutters?
2-stroke models are lighter and run on petrol mixed with 2T oil, while 4-stroke models run on pure petrol, produce less noise, and have better fuel efficiency.
Is government subsidy available for buying a brush cutter?
Yes, eligible farmers can apply for subsidies under SMAM and state mechanization schemes through agrimachinery.nic.in.
