. Introduction:
A Disc plow consists of a series of individually mounted, inclined disk blades on a frame supported by furrow wheel. A tractor –mounted disk plow has only a rear furrow wheel. Disk plows are most suitable for conditions under which mould board plows do not work satisfactory, such as in hard, dry soils, in sticky soils where a mould board plow will not scour, and in loose, push-type soils such as peat lands. A mould board plows, in soils and moisture conditions where it works properly, does a better job than a disk plow and has a lower specific draft.
