A hydrostatically power-splitting transmission (10), particularly for agricultural and construction equipment, comprises at least two hydrostats (H2), which are hydraulically connected to each other and operate as pumps or as motors, wherein at least one of the hydrostats (H2) can be adjusted or pivoted by means of a controller (16, 20, 21; SK1,...SK4), mechanical coupling means (K1, K2; Z1,...,Z12), which couple the hydrostats (H1, H2) to an inner drive shaft (W1) and an inner driven shaft (W7), a housing (14, 31) comprising a cover (14) and a housing bottom part (31), wherein the hydrostats (H1, H2), the inner drive and driven shafts (W1, W7), and the mechanical coupling means (Z7, Z9) are disposed and attached on the bottom of the cover (14), and in the lower housing part an outer drive shaft accessible from the outside and a driven shaft are supported, which are operatively connected to the inner drive shaft or driven shaft when the housing is assembled. In such a transmission, a compact design, while sim
