Design Principles of Basin Lister Cum Seeder

M. Muthamilselvan, R. Manian, K. Kathirvel

Abstract


The creation of a multitude of small basins in the cultivated field is an effective way of retaining moisture and controlling both wind and water erosion and hence boosting crop yield in areas of low rainfall. The simplest way to create these basins is to set the land up in ridges and furrows, used to build a small dam wall at specified intervals in the furrow with a mechanical device and that is known as basin lister.  So if a basin lister cum seeder as an attachment to tractor drawn cultivator is developed, it can perform ploughing, basin formation and sowing simultaneously.  Keeping the abovefact in view, the basin lister cum seeder was designed as a rear mounted attachment to four wheel tractor.  It is seenfrom the statistics of sale of tractors that 35-45 hp range tractors occupied the major share in the agricultural sector and hence the implement was designed to suit the 35-45 hp tractors and help the major percentage of tractor users.  The formation of basins will be in between two adjacent rows of 0. 45 m. The top width of basin was restricted to 0. 30 m and the bottom width of basin considered is 75 mm. The width of the unit is arrived as 1. 80 m which is the normal width of tractor drawn cultivator.  In this paper, the design requirements for the basin lister, the step by step procedure to design the functional components required for basin lister as an attachment to tractor drawn cultivator and constructional features are described.
