First activity in any crop cultivation practice is the tilling of soil to make a desirable seed bed for germination of seeds or seedlings. A major part of tractor energy is utilized in seed bed operation leading to high operating cost for farmers. The Spading Machine developed at CSIR-CMERI reduces the cost of tillage operation and improves the effectiveness of tillage operations. The design of CSIR-CMERI spading mechanism is advantageous in reducing vibration and enhancing the comfort of tractor operator. As compared to other tillage implements, the machine forms no compaction of subsurface soil and improves the aerobic quality and drainage of soil. The machine can also incorporate large organic material due to its homogeneous working and uniform turning of soil. The spading machine is powered by tractor PTO which rotates at standard speed of 540 rpm, power is transmitted to the crank through the speed reduction gear. This machine has a working width of 1800 mm and it can be operated with any tractor having power greater than 45 HP. The main advantage is less compaction in subsurface soil layers thereby eliminating the need for sub-soiling. This is due to the fact that soil breakup during spading is similar to manual hoeing as it imitates the manual soil cutting action.
