Description:
BACKGROUND
Field of Invention
[001] Embodiments of the present invention generally relate to a paddy weeder and particularly to a multi-row paddy weeder.
Description of Related Art
[002] In traditional agriculture, a process of weeding paddy fields, particularly in multi-row setups, has been labor-intensive and time-consuming. Conventional methods often rely on manual labor or engine-powered machinery, which can be costly, environmentally unfriendly, and do not effectively target weeds in multi-row configurations.
[003] However, existing engine-powered paddy weeders are cumbersome, require frequent maintenance, and contribute to noise pollution and carbon emissions. Furthermore, the use of engines in agricultural equipment poses safety risks and is not economically viable for small-scale farmers or in remote areas with limited access to fuel and maintenance services.
[004] Moreover, there is a growing need for a sustainable, cost-effective, and efficient alternative for weed management in multi-row paddy fields. An engine-less solution could significantly reduce operational costs, minimize environmental impact, and improve safety while enhancing productivity in agriculture.
[005] There is thus a need for an improved and advanced multi-row paddy weeder that can administer the aforementioned limitations in a more efficient manner.
SUMMARY
[006] Embodiments in accordance with the present invention provide a multi-row paddy weeder. The weeder comprising: a frame. The frame comprises a wheel shaft adapted to enable a rotation of wheels upon application of an external force on the frame and a first disk arranged with the wheel shaft.
