Weeding and other post-planting intercultural operations are quite labour intensive and use of herbicides is both expensive and undesirable. An inter-row rotary cultivator with high ground clearance and adjustable row spacing and operated by tractor is an ideal choice for weeding/intercultural operations. The distance between the rows depending upon the condition and the type of the crop can be adjusted by sliding each unit on the main frame since each unit is independent of the others.
