Abstract:
Spading machine is a tillage implement which loosen and break up the soil. The principle of spading machine is similar to digging of soil by spade. Spading machine is designed to approximate the effect of proven smaller-scale hand digging tool for the purpose of deeper aeration and effective integration of organic matter. The machine was developed in research workshop, Department of Farm Machinery and Power Engineering, KCAET Tavanur, KAU Thrissur. The evaluation of machine was conducted in soil bin which, is containing laterite soil with 13.87% moisture content and 1.73 gcc^-1 bulk density. The minimum and maximum field capacity of spading machine were 0.03 and 0.064 ha h^-1 with forward speed 1 and 3 km h^-1 respectively. The efficiency of spading machine was varied from 75 to 80% at 1 and 3 km h^-1 respectively. The depth of operation 13 cm obtained at low crank speed 165 rpm.
