A Study on Dimensional Variations in Commercial Cultivator Tines and Reversible Shovels in Comparison to Bureau of Indian Standards Norms

Accelerated demand for farm equipment has encouraged many producers to initiate production of farm machinery. Bureau of Indian Standards (BIS) provide standards for cultivators but commercial agricultural machinery manufacturers design based on trial and error basis without knowing the concept of optimization, which in turn leads to unnecessary design and cost and also affects equipment performance. With respect to this, study was undertaken to check the dimensions of commercially available cultivator tines (Rigid and spring) and reversible shovels. Based on the usability and availability commercially available rigid and spring cultivator tines and also reversible shovels were selected by conducting survey around Udaipur region. The dimensions of selected cultivator tines and reversible shovels were measured by using vernier calliper and measuring tape. The dimensions of selected rigid and spring cultivator tines found almost higher values as compared to BIS recommended value. Also among shovels, shovel 1 (Sh1) and shovel 2 (Sh2) measured higher values as compared to BIS recommended value, whereas shovel 3 (Sh3) found minimum values as compared to BIS recommended value.
