The cones are comprised of plastic material and the steel blades are embedded in it. It has a single row and is operated by a single person in a push and pull operation. It has two conical rotors mounted in tandem with opposite orientation. Smooth and serrated blades are mounted alternately on the rotor to uproot and bury weeds when the rotors create a back and forth movement. Each cone has 6 serrated blades and 6 plain ones, each of 2 mm in thickness. Design Specifications

Manufacturer Specified Performance Parameters
Vetted Performance Status
Through field evaluations in lowland paddy fields the effective field capacity, weeding index, pushing force and other factors were measured for KSNM cono weeder with moulded cones and compared to commercial ones with mild steel cones. Results are shown in the table.
|Type of weeder||Difference over commercial weeder, percent|
|Commercial weeder||Cono weeder with plastic moulded cones|
|Effective field capacity, m2/h||190.0||265.0||28.30|
|Weeding index, per cent||75.2||81.1||7.04|
|Pushing Force, N||43.3||37.50||-(13.39)|
|Plant damage, percentage||6.1||5.90||-(3.27)|
Safety hazards related to this product include blades on the cones.
