Engine types and mounting configurations
- 2-Stroke engines: Lightweight, economical units operating at high RPM; requires pre-mixing 2T engine oil with petrol.
- 4-Stroke engines: Run on pure petrol without oil mixing; deliver smoother engine sound, lower vibration, cleaner exhaust, and superior fuel economy.
- Backpack brush cutters: The engine rests on a padded backpack harness with a flexible drive shaft, reducing arm fatigue during long harvesting sessions.
- Side-mount (straight shaft) cutters: Classic rigid straight shaft carried on a shoulder strap, offering direct power transfer and high maneuverability.
Cutting attachments and field applications
Equipped with interchangeable cutting heads: 2-tooth or 3-tooth steel blades for tall green fodder (Napier grass, lucerne, sorghum) and wild brush; 40 to 80-tooth tungsten carbide-tipped (TCT) circular saw blades for cutting wheat and paddy stubble cleanly; nylon trimmer lines for mowing grass along orchard bunds and stone walls without blade breakage; and mini-cultivator weeder attachments for shallow weeding between vegetable rows.
Operator safety and SMAM government subsidy
- Always wear safety eye goggles, a face shield, heavy-duty shoes, and ear protection to guard against flying stones and debris.
- Grease the gearbox head at the blade spindle every 25 to 30 operating hours.
- Brush cutters qualify for 40% to 50% purchase subsidies under the Sub-Mission on Agricultural Mechanization (SMAM) on agrimachinery.nic.in.

Common questions
What is the primary benefit of a 4-stroke grass cutter over a 2-stroke model?
4-stroke models run on pure petrol without needing oil mixing, produce less exhaust smoke, have lower vibration, and offer better fuel efficiency.
Which cutting blade is best for harvesting green fodder like Napier grass?
A 2-tooth or 3-tooth heavy-duty steel blade slices cleanly through thick fodder stalks without shredding or lodging.
Where can farmers apply for government subsidies on brush cutters?
On the central SMAM portal (agrimachinery.nic.in) or their state department of agriculture mechanization DBT portal.
