Abstract
The mechanization of Indian farms is imperative to enhance input use efficiency, reduce human drudgery, cost of production and to address issues of labour scarcity and timeliness of farm operations. Digging of trenches for laying pvc pipes in sprinkler and drip irrigation system has become drudgery by human labour, more expensive and time consuming. Commercially available machines are high capacity, more cost of operation and not affordable to the small and marginal farmers. To overcome this problems, a small tractor operated trencher was designed and developed. The developed trencher was evaluated in the field at a 1.5,2,2.5 km/h forward speeds. During field trails it was observed increase in forward speed from 1.5 to 2.5 km/h resulted in decrease in depth of trench, fuel consumption and capacity of auger. Increased in forward speed resulted in increase in length of trench.
