Strength, toughness, machinability, and economy account for the use of ferrous forgings in off-highway and heavy construction equipment, and in mining machinery. In addition to engine and transmission parts, forgings are used for gears, sprockets, levers, shafts, spindles, ball joints, wheel hubs, rollers, yokes, axle beams, bearing holders, and links. Farm implements, in addition to engine and transmission components, utilize key forgings ranging from gears, shafts, levers, and spindles to tie-rod ends, spike harrow teeth, and cultivator shanks.
