Design specifications Component and Operation overview including power, portability, facility requirements, preventative maintenance and user training requirements

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.

Manufacturer specified performance targets Designer / Manufacturer specified targets

It can cover 0.1-0.12 hectare per day of 8 hours of operation, saving 50% labor and 40% cost.

Performance targets include: low cost, easy to operate, no chemical residue, facilitates good aeration, and enable better development of root system.

Vetted performance Findings of manufacturer evaluations or independent testing centers

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	Difference over commercial weeder, percent
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)
Performance Index	1358.1	2031.90	49.61
Weight, kg	7.5	6.1	-(18.6)
