Weeding is one of most important operation in crop cultivation.
Although, there are several methods are available of mechanical
weeding, but weeding operation
poses a special problem in ridge
planted crop. Therefore, to address
this problem a ridge profile power
weeder was developed with 2.20
kW petrol-start kerosene-run engine
and evaluated for its performance
in terms of weeding efficiency,
plant damage percentage and field
capacity. Weeder comprised of main
frame, handle, cutting blades, rotor
shaft, belt and pulley, engine and
ground wheel. Experiments were
conducted at three different levels
of each parameter viz, soil moisture
content (15.26 ±0.96, 12.42 ±0.52
and 9.44 ±0.68%), blade types (Ltype, C-type and Flat-type) and
gang speed (160, 180 and 200 rpm).
Results revealed that, C-type blades
were most suitable at gang speed of
200 rpm and 15.26 ±0.96% (d.b) soil Weeding is one of most important operation in crop cultivation.

Results revealed that, C-type blades
were most suitable at gang speed of
200 rpm and 15.26 ±0.96% (d.b) soil moisture content with average weeding efficiency, plant damage, actual
field capacity of 83.93%, 1.77%, and
0.066 ha h-1, respectively. The total
estimated cost of machine was Rs.
27,600 ($460) and its cost of operation was Rs. 640/- per ha. The saving in cost of operation was 88.3%
as compared to manual weeding
(Rs. 5,470). Time saving with ridge
profile power weeder as compared
to manual weeding was 93.93%.
The ridge profile power weeder had
a breakeven point at 179.38 h yr-1
with a payback period of 2.74 years.
