High levels of crop residues present a constraint to the adoption of conservation tillage, because residues mechanically interfere with seeding operations. Improved seedling equipment or residue removal may be necessary for successful direct drilling practices. Many equipment modifications have been done to overcome these problems, but still there are many drawbacks. An approach that has not been well explored is the use of powered devices to move the residue. Powered residue manipulating devices also offer flexibility in design alternatives. They could be designed to skim above the ground to avoid soil disturbance and are not limited in speed to the drill travel speed. With speed and control over the direction of rotation a variety of residue cutting, chopping and pushing devices can be considered. Furthermore, a powered device can be adjusted to direct residue where desired. Keeping the above aspects in view the present work was undertaken to develop a suitable attachment for seeding machines, which can help in sowing wheat crop in various field residue conditions.
