Weed management is a tedious task. If weeds aren't effectively controlled, it will negatively affect crop output, quality, and harvest costs. To grow a successful crop, weed management frequently requires significant resource inputs. Review and discussion of inter-row and intra-row mechanical weeding, two different mechanical weed control techniques. In particular, reviews and comparisons of the most popular manual inter-row mechanical weeding tools are made in accordance with their functional principles. The more challenging area of intra-row mechanical weeding is reviewed, and manually operated intra-row mechanical weed control tools are compared. Along with various cutting edge solutions for intra-row mechanical weed control discovered in industry and the research community, the state of the art in automated mechanical weeding is being explored. Highlights:  The majority of mechanical weeders have weeding efficiency between 60 and 80 percent. Review Article
