Abstract
A field investigation was carried out to isolate the forces acting on various components of a mole plough using extended octagonal ring transducers. The phenomenon of cutting the soil in stages in order to reduce the draught requirement of cooling operation was applied by cutting a slot at different depths prior to cooling operation and it was observed that a significant reduction in draught (upto 37%) was achieved when a slot was cut at 240, 340, 420 mm depth prior to moling operation. Mole plough leg contributed 74% of the total draught force. Soil disturbance increased at depth when slot was cut prior to moling operation. Total resultant force acted at 8.15° leg resultant at 4.4° and Cartridge resultant at 37.9° to the horizontal.
