Key types of agricultural threshers
- Multi-crop thresher: Versatile tractor-PTO driven unit capable of handling wheat, mustard, soybean, chickpea, and millets by switching concave sieves and adjusting drum speed.
- Spike tooth thresher: Employs spiked peg cylinders, widely adopted for wheat and pulses to effectively shatter pods without cracking seeds.
- Axial flow thresher: Feeds crop material axially along the cylinder, commonly utilized for wet paddy and soybean crops with minimal grain damage.
- Harambamba thresher: Heavy-duty tractor-drawn thresher designed for fast wheat threshing with high output capacity and straw crushing capability.
Operational safety and maintenance rules
Operators must wear fitted clothing, avoid loose scarves, and always feed crop material into the hopper using wooden pushers rather than bare hands. The tractor PTO shaft must be protected by a rotating safety shield. Regular lubrication of bearings, checking V-belt tension, and cleaning the blower assembly prevent grain clogging and overheating.
Subsidy under SMAM scheme
The Sub-Mission on Agricultural Mechanization (SMAM) offers capital subsidies to farmers for purchasing government-approved threshers tested by Central Farm Machinery Training and Testing Institutes (CFMTTI). Applications are submitted online through the national agricultural machinery portal.

Common questions
How does a multi-crop thresher adjust for different crops?
Operators change the concave sieve size, adjust the cylinder clearance, and modify drum RPM according to the crop grain size.
What is the critical safety rule while feeding a thresher?
Never feed crops with bare hands or loose sleeves; always use the mechanical feeding chute and standard wooden pushers.
Where can farmers apply for thresher subsidies?
Eligible farmers can apply online via the official SMAM portal (agrimachinery.nic.in) or their respective state agriculture engineering department.
