Abstract: Mouldboard ploughs are used widely for primary tillage. There are two types of mouldboard ploughs according to turn the furrow slices: one-way version and a two-way version. One-way versions are designed to turn the furrow slices only to the right. Two-way versions or reversible mouldboard ploughs are designed to turn the furrow slices to the right and left. The two sets of bottoms are mounted on a common frame that is rotated 180o about a longitudinal axis to change from one set to the other. The swing plough was developed as an alternative to the conventional reversible mouldboard plough. The energy requirements of mouldboard ploughs are high. Energy requirement of mouldboard ploughs depend on working depth of the plough, working witdh, number of bottoms, type of mouldboard, soil moisture content, soil bulk density, draft force, soil penetration resistance, forward speed. This study aimed at comparing total energy requirement in relation to the inputs of fuel-oil energy, machine production energy and human labour energy for the standard mouldboard plough, conventional reversible mouldboard plough and swing plough. Mouldboards of standard mouldboard plough and conventional reversible plough used in the study have cylindroid and the bottoms of swing plough have square shaped. The ploughs examined are tractor mounted type and have two bottoms. The total weights of standard mouldboard plough, conventional reversible mouldboard plough and swing plows are 205, 402 and 270 daN respectively. During the tests, the ploughs was operated at 25 cm average furrow depth in condition of medium heavy soil. Fuel-oil energy, machine production energy, human labour energy and total energy requirement of ploughs were calculated by using equations. As a result of the study, it was determined that the total energy requirement per unit area (926.00 MJ ha-1 ) of the swing plough was lower than the standard mouldboard plough (1085.49 MJ ha-1 ) and conventional reversible plough (1244.25 MJ ha-1 ). The total energy requirement of the swing plough is 14.69% less than that of the standard mouldboard plough and 25.58% less than that of the conventional reversible plough.
