A controlled differential-gear system includes an input differential, an output differential, and an idler gear positioned between the two differentials to operate the output differential as a subtractive type when the input differential operates as an additive type. Brake means is arranged to brake one or the other side of the differentials to vary the output speed through an infinite range from maximum reverse, through zero, to maximum forward. Three arrangements of the differentials and two embodiments of the brake means are illustrated in the drawings.
