Types of mechanical weeding tools
Weeding tools are selected according to crop geometry, row spacing, and soil moisture.
Major implement categories:
- Hand hoes and grubbers (Khurpi / Kudali): Ergonomic handheld blades for seated, close-proximity weeding in dense vegetable beds.
- Wheel hoes: Pushed manually along line-sown crop rows, equipped with reversible sweeps, V-blades, or tines that slice weeds at shallow root depths.
- Cono weeders (rotary paddy weeders): Specifically designed for wet direct-seeded and SRI paddy, utilizing conical rollers that churn weeds into the mud as green manure.
- Motorized power weeders (power tillers / rotary cultivators): Small petrol or diesel-engine units that cultivate between wide rows of sugarcane, cotton, and orchards.
Agronomic benefits of mechanical weeding
Mechanical weeders provide essential soil physical benefits in addition to weed eradication.
Core benefits include:
- Soil aeration: Loosens compacted surface soil, improving oxygen diffusion into active root zones.
- Capillary breakdown: Creates a dry surface dust mulch that conserves deep sub-soil moisture during dry weather spells.
- Herbicide-free: Essential for certified organic farms, zero-budget natural farming, and preventing chemical-resistant weed development.
Subsidies under Sub-Mission on Agricultural Mechanization
Under SMAM and state mechanization programs, the Government of India provides capital subsidies for purchasing manual wheel hoes, cono-weeders, and power weeders. Farmers can apply online through the centralized mechanization portal at agrimachinery.nic.in.

Common questions
What is a cono-weeder and where is it used?
A cono-weeder is a manually pushed implement with conical rotating rollers used for weeding and soil churning in line-planted wetland paddy fields.
How does mechanical hoeing conserve soil moisture?
It breaks up surface soil capillary pores, forming a loose soil mulch that interrupts evaporative water loss from the root zone.
Are subsidies available for purchasing motorized power weeders?
Yes, capital subsidies are available under the SMAM scheme accessible through agrimachinery.nic.in.
