Development and optimization of mini tractor mounted cod crusher cum planker

In tillage tools used in India faces problem like, poor soil-tire interface, clod formation, compaction due to heavy traffic and timeliness in operation. Overcome to this practical problem, it was planned to develop a clod crusher cum planker for better seed bed preparation. To achieve this objective a prototype implement consisting of three different types of clod crusher rollers’ like square spike, round spike and spiral arrangement of spike were developed. The developed implement was tested in the field to evaluate its performance. Their results were analyzed in terms of breaking of clods and machine parameters. The effects of treatments on soil physical properties like soil bulk density, clod MWD were evaluated. Machine performance parameters like fuel consumption, field efficiency and cost of operation were also studied. The optimum values of clod MWD, clod crushing field efficiency and fuel consumption were found 13.64 mm, 78.37 % and 7.02 l/ha respectively. The operating cost were found 882, 1050 and 988 ₹/ha in case of square spike, round spike and spiral arrangement respectively. Better performance in terms of breaking of clods was obtained using clod crusher of square spike. Using clod crusher a farmer can save money in comparison to traditional methods of preparation of seedbed. | Development and optimization of mini tractor mounted cod crusher cum planker
